Issues with setting attrs and Media when creating my own widget
I'm trying to subclass the Select widget, so that I can create an
editable scrolling list (done via JavaScript code that I found).
My entire class is as follows:
--Code--
from django import forms
class ComboBox(forms.Select):
class Media:
js = ("/js/wise/comboBox.js",)
def __init__(self, choices=()):
# Set up calls to the combo box JavaScript
attrs = {
"onFocus": "return combo_focus(this);",
"onChange": "return combo_change(this);",
"onKeyDown":"return combo_keydown(this, event);",
"onKeyPress": "return combo_keypress(this, event);",
"onKeyUp": "return combo_keyup(this, event);",
"onClick": "return combo_click(this, '');"
}
super(ComboBox, self).__init__(attrs, choices)
--Code--
The form that uses it looks like:
--Code--
class TestTargetForm(forms.Form):
# Family name
fname = forms.ModelChoiceField(
queryset=TargetFamily.objects.all(),
required = False,
label = "Family Name",
empty_label = "[Match All]",
widget = ComboBox
)
--Code--
Issue #1:
I figured out that I can add HTML attributes by setting the 'attrs'
variable. Which means I only need to create __init__() and not
render(). That works fine except that I want to call a JavaScript
function with a string (the onClick attribute).
The single quotes get escaped. How would you pass a string to a
JavaScript function using 'attrs'?
Issue #2:
The 'class Media' definition is being ignored when running through the
Django server. I can import my class in python, instantiate the class,
and print the media:
python manage.py shell
>>> from share.widgets import ComboBox
>>> print ComboBox().media
but when I look at the web page source coming back from the Django
server, that text isn't there. Did I need to do
anything else?
I would appreciate any help either by example or pointers to examples or
docs. I looked in the Django source and it looks like the admin stuff
sets Media just like I'm doing. The Django doc page for Media also
shows an example that looks just like what I'm doing (doesn't mention
that I have to do anything else).

Re: Your IDE of choice
I have omnicomplete working (haven't used it too much yet). I have this
in my $HOME/.vimrc file:
--.vimrc--
if has("autocmd")
autocmd BufRead *.py set smartindent
\ cinwords=if,elif,else,for,while,try,except,finally,def,class
autocmd FileType python set omnifunc=pythoncomplete#Complete
autocmd FileType javascript set
omnifunc=javascriptcomplete#CompleteJS
autocmd FileType html set omnifunc=htmlcomplete#CompleteTags
autocmd FileType css set omnifunc=csscomplete#CompleteCSS
endif
" Allow to be used instead of like other IDE's do
" for auto-completion
inoremap
--.vimrc--
All 'autocmd' lines should be single lines.
Also, I have vim starting automatically importing the Django db. I have
a little script (below) that will automatically find my settings.py file
and start vim. I do this by starting at the location of the file on the
vim command line and working upwards in the directory structure until I
find it:
--dvim--
#!/packages/bin/python
"""
Start vim for Django files
"""
import os
import sys
args = sys.argv
# Get our starting directory to look for the settings file. If no
# filename is given, start in the current directory
if len(args) > 1:
# If multiple filenames are given on the command line, we assume
# the same Django settings apply to all
dir = os.path.realpath(os.path.dirname(args[1]))
else:
dir = os.path.realpath(".")
# Start looking for the settings file, going up one directory if we
# don't find it until we hit the top of the filesystem
while not os.path.exists(dir + "/settings.py"):
if dir == "/":
# We are as far as we can go and didn't find anything
dir = None
break
# Go up one directory
dir = os.path.dirname(dir)
if dir != None:
# Found the settings file
os.putenv("PYTHONPATH", os.path.dirname(dir))
os.putenv("DJANGO_SETTINGS_MODULE", os.path.basename(dir) +
".settings")
os.system("/packages/bin/vim '+python from django import db' " + \
" ".join(args[1:]))
else:
raise IOError("Django settings file not found")
sys.exit(0)
--dvim--
I'm sure some lines are probably getting wrapped.
I only use Django on Unix/Linux so I'm guessing it would need some
tweaking for Windows.

Glad it was of use. Except for the script which I wrote myself, all the

Re: What do you use as a build tool (like Ant or make)
I'm not doing unit tests at the moment, but for build and release I use Waf (http://code.google.com/p/waf/), which happens to be written in Python (including the configuration files).

Looking for an example on how to use us.forms.USZipCodeField
Using Django v1.0. One of my models is a standard address table. I knew about us.models.PhoneNumberField, so I used that for a phone number field. It uses us.forms.USPhoneNumberField so that validation works nicely on an Admin form. Same thing for USStateField. While there is are phone number and US state model fields, there doesn't seem to be the equivalent zip code field, even though there is a zip code form element. Not sure why that would be. I've searched around, but the best I get are syntax errors (at least Python/Django complains about a syntax error when I try to set up a form and have my zip code field use USZipCodeField). Given that, how do you actually tell the Admin form to use us.forms.USZipCodeField for a given model field or somehow associate the zip code model field with USZipCodeField? Right now my zip code model is a CharField() for lack of a better choice.

Re: Looking for an example on how to use us.forms.USZipCodeField
Thanks for the information. I eventually stumbled across a web page that mentioned formfield_for_dbfield(). I wound up doing this: class AddressAdmin(admin.ModelAdmin): def formfield_for_dbfield(self, db_field, **kwargs): if db_field.name == "Zipcode": return USZipCodeField(**kwargs) else: return super(AddressAdmin,self).formfield_for_dbfield(db_field, **kwargs) where my field name is "Zipcode". Since this was the only zipcode field, this seemed like the easiest solution.

Re: http links without using URLs.py
I ONLY use it for development with the Django server. I only set up to serve static pages when DEBUG = True (as they show toward the bottom of the page). No need to change links on the production server (apache + mod_python) because the URLs are a different location than what I have set up for mod_python. You set up mod_python using if you are using Apache. This tells apache that ONLY what matches the specified location will use mod_python. An example: SetHandler python-program PythonHandler django.core.handlers.modpython PythonInterpreter my_arbitrary_unique_name_here PythonPath "['/my/django/code'] + sys.path" SetEnv DJANGO_SETTINGS_MODULE WebSite.settings SetEnv PYTHON_EGG_CACHE /tmp/.python-eggs PythonDebug On With this setup, only those URLs that have /my_django_site/ will go to Django (via mod_python). Any other URLs will get serviced by Apache as normal. It is quite discouraged to have Django serve static pages on a production server since it's not meant for that, so it's slow and inefficient.

Re: http links without using URLs.py
Eggs seems to be something related to python packages, not sure exactly what they are used for. I needed the PYTHON_EGG_CACHE because my web server could not write to the default egg cache directory and so I had it use a temp place. Perhaps somebody else can better explain eggs.

Any way to NOT escape a percent sign using 'contains'?
According to the docs, when using 'contains' in filter() a percent sign or underscore is automatically escaped. However, in my case I want the resulting SQL to use the percent sign. I know 'contains' will fill in the outside percent signs, but it escapes the percent sign in my string. So that calling: Entry.objects.filter(headline__contains='a%b') will result in: SELECT ... WHERE headline LIKE '%a\%b%'; but I want it to be this instead: SELECT ... WHERE headline LIKE '%a%b%'; This there an easy way to do this? I could use regexp, but I didn't want people to know that they would have to use "a.*b" instead of "a*b", just trying to make it simplier for myself and the people using the system. -- Adam Stein @ Xerox Corporation Email: a...@eng.mc.xerox.com Disclaimer: Any/All views expressed here have been proven to be my own.

Re: Any way to NOT escape a percent sign using 'contains'?
Thanks for the advice. I was kinda thinking I would have to use regex.
I hadn't thought of puting the replace() in a custom cleaning method,
but I agree that sounds like a good place to put it.

Re: Changing default app url in development server
I do something similiar where I have an extra item in the url. To get Apache and the Django server to match, I just add the extra part in urls.py that I'm matching. So instead of something like: (r'^admin/(.*)', admin.site.root) in Alex's case, it would be: (r'^peergw/admin/(.*)', admin.site.root) The same would go for any other match, just add the 'peergw' in front. That way, the exact same URL can be used in both places.

Any way to show progress during a short process job?
Maybe somebody can suggest how to get the functionality I'm trying to
duplicate. I looked and can't find anything that seemed similiar.
I have a form with checkboxes. User selects one or more and submits the
form. The processing currently goes like this:
1) Write JavaScript to display moving progress bar
2) Process based on checked boxes (which in my specific example is to
copy the specified databases into a sandbox area)
3) Write JavaScript to turn off progress bar
The database copying is short, up to about 20 seconds. Short enough to
let the user wait, long enough that I want to indicate the computer
hasn't frozen :-{}
It seems that I can only return HTML to be displayed once from a view.
Is there a way to get the functionality described above somehow?

Re: Any way to show progress during a short process job?
Thanks Kevin and Malcom for responding.
Kevin is right in that I don't need AJAX. I came up with a different
method that also allows me to change the string above my progress bar to
reflect what I'm actually doing at the moment.
My method (roughly) involves setting the HTTPResponse content to an
iterator and having the iterator split a rendered template. It yields
the first part which would load the progress bar and display it. Then
it calls a passed in callback function to do the actual processing, then
yield the last part of the rendered template which would turn the
progress bar off. If anybody is interested, I can post code and go
through exactly what I do.
Another thing I tried for fun was passing in a reference to a Python
function to the template. Had the template call a tag I made myself
which then calls the passed in Python function. Turns out, you can do
that but the display wasn't updated properly.

Can I limit the choices in a ContentType field in admin?
Trying to create a generic FK using ContentType. In admin, the menu lists all the models. Since I only ever need to select 1 of 2 different models, anyway to limit the choice? Setting the choices attribute as Django complains must be a "ContentType" instance ContentType.objects.get() returns an instance of a particular model, not ContentType (as one would expect), so I'm not sure how to create an instance with the particulars I need to point to something specific in the choices list. Here's what I have: from django.db import models from django.contrib.contenttypes.models import ContentType from django.contrib.contenttypes import generic class GenericFKExample(models.Model): CHOICES = ( (ContentType.objects.get(model="model1"), "Model 1"), (ContentType.objects.get(model="model2"), "Model 2"), ) content_type = models.ForeignKey(ContentType, choices = CHOICES, null = True, ) object_id = models.PositiveIntegerField( null = True, ) content_object = generic.GenericForeignKey( "content_type", "object_id" ) Obviously, if I don't use choices, it works but then I have a very long list of model choices. -- Adam Stein @ Xerox Corporation Email: a...@eng.mc.xerox.com Disclaimer: Any/All views expressed here have been proven to be my own.

Any way to save the output of a template filter to another variable?
Using Django v1.0.2. Didn't see or find anything obvious, so I thought I would ask. In my specific example, I would like to save the output value from the 'length' template filter so that I can send it to the 'expr' tag (expr is a tag that allows you to effectively execute python statements and save the result to another template variable). I could make a specific tag or filter, but I thought it would be more general purpose to be able to save the length value and pass that in to expr to use in an equation (need to multiply the length of a list). Assuming Django native template can't do it (which is what it looks like), anybody know of any tags that can do this? -- Adam Stein @ Xerox Corporation Email: a...@eng.mc.xerox.com Disclaimer: Any/All views expressed here have been proven to be my own.

Authentication integration with Netegrity SiteMinder?
Using Django v1.1/mod_wgsi v2.5. I'm forced to use CA's Netegrity SiteMinder to authenticate users. I couldn't find anything regardng integration with Django (so that Django can provide authorization). I have integrated Django authentication with an LDAP server, but I need to use SiteMinder instead because of corporate policy. Figure I would ask to see if anybody has already done this before I try to figure this out from scratch. SiteMinder gives me the login name in an environment variable which I can then tie into the Django user system. -- Adam Stein @ Xerox Corporation Email: a...@eng.mc.xerox.com Disclaimer: Any/All views expressed here have been proven to be my own.

Using the login page AND RemoteUserMiddleware depending on user?
Couldn't find anything regarding this. All authentication schemes seem to assume you are only doing it one way. Using Django v1.1. I need the Django admin to come thru the login page as normal. However, every other account is authenticated by an external authentication source. I can use RemoteUserMiddleware for the external authentication, but then I can't log in as the Django admin (since RemoteUserMiddleware ALWAYS gets the user name from REMOTE_USER). Anybody deal with this before? It's easy enough to subclass RemoteUserMiddleware, but how do I tell when to use REMOTE_USER and when to use what user is already set to? -- Adam Stein @ Xerox Corporation Email: a...@eng.mc.xerox.com Disclaimer: Any/All views expressed here have been proven to be my own.

Re: Can I limit the choices in a ContentType field in admin?
I wound up doing it that way as well except I used the model name rather
than the ID:
data_type = models.ForeignKey(ContentType,
limit_choices_to = {"model__in": ("model1", "model2")},
)

ValidationError exception message not coming through
Running Django v1.0.2.
I have a form with a file field. The file needs to be in PDF format, so
I have a clean routine that checks that (modified slightly to NOT wrap
lines):
def clean_PDF_File(self):
"""Verify that the content is PDF format"""
type = "application/pdf"
if self.cleaned_data["PDF_File"].content_type != type:
raise forms.ValidationError("File must be in PDF format")
return self.cleaned_data["PDF_File"]
A simplified view looks like this:
if form.is_valid():
else:
print "Errors = [", form.errors, "]"
I'm expecting form.errors to contain the message I gave to
ValidationError(). Instead, this is what prints out:
Errors = [ PDF_FileThe submitted file is empty. ]
What happened to my error message? I can't pass the correct error
message to the form if I don't receive it in the first place. When the
field is blank, I get the correct error message that I expect to see:
Errors = [ PDF_FileThis field is required. ]
Any thoughts on what else I might try or look at?

Re: ValidationError exception message not coming through
I did supply a file, just NOT a PDF format file which causes
ValidationError to be raised (yea, probably want to make sure that
wasn't the problem :-{}) When I don't supply a filename, I do get the
correct error message back in form.errors.
But you could be correct about the FileField's clean method. If I
detect a file isn't PDF format, I raise the exception so no filename is
passed back. Could it be that the FileField clean method is called
AFTER mine? I know my clean method is being called.

Using Django authentication for web pages outside Django?
I'm trying to figure out a way to use Django authentication to control access to web pages (on the same web server) that are NOT under Django. I have found some information regarding setting up Apache for basic authentication using mod_wsgi, but in this case Apache puts up it's own login window. I'm looking for a solution using Django and/or Apache directives that would put up Django's login page. It should look exactly the same as if the URL were under Django control. Has anyone done anything like this? I'm currently using Django v1.0.2 and Apache v2.2 but can upgrade either if necessary. -- Adam Stein @ Xerox Corporation Email: a...@eng.mc.xerox.com Disclaimer: Any/All views expressed here have been proven to be my own.

Thanks for responding and for the idea. I'm also migrating, but security seems to be a bigger deal than getting the rest migrated at the moment, hence the need to authenticate for the old stuff.

Re: problem using ajax in django
Don't know if this will help, but when I use AJAX, I don't set the
mimetype in HttpResponse(), I just pass simplejson.dumps() to
HttpResponse():
return HttpResponse(simplejson.dumps(response))
This approach works with Firefox, IE6, & IE7.

Re: Error loading MySQLdb module: libmysqlclient_r.so.16 - Help please
LD_LIBRARY_PATH variable is the correct one to use when running from your account (not to go into the discussion as to why some people think LD_LIBRARY_PATH is evil), as evidenced when you run python on the command line. In the case of Django running through a web server, the web server is not picking up the LD_LIBRARY_PATH setting you are using in your own personal account. The reason editing ld.so.conf works, is because you are globally setting the library path to search. Since ld.so.conf is a 'global' setting, your Django application (python) picks it up from the system and finds the library. Another way (what I do) is to compile Python with the MySQL lib directory (--with-libs configuration argument) so that Python can find the library whenever it runs (no matter who's running it, me -- or the web server).

Re: Moving the .py(c|o) files out of the app?
Another option is to use a build tool. I use waf (http://code.google.com/p/waf/), a Python-based framework for configuring, compiling and installing applications. I have it set up so that it compiles the Python files, copies Python and other types of files to an installed location, then remove the Python source files from that installed location.

Trouble setting a form field's value in clean()
Running Django v1.1.1 on Apache v2.2.8 with Firefox v3.5.4.
I have a very simplified and unreal example below to demonstrate what's
happening.
class MyForm(forms.Form):
string1 = forms.CharField()
string2 = forms.CharField(widget = forms.HiddenInput())
def clean(self):
cleaned = self.cleaned_data
if not cleaned.has_key("string2") and
cleaned.has_key("string1"):
cleaned["string2"] = string1
return cleaned
As seen, both 'string1' and 'string2' are required. In the clean()
method, if string2 isn't defined, I set it to a value. For my simple
case, I'm just setting it to the value of another field on the form.
What happens is that Django comes back with an error message because
'string2' is required and has no associated value. Is there any way to
set a field value that get's POST'd? Even if I make 'string2' not
required (so it winds up being an empty string), there still doesn't
seem to be a way to change the empty string to have a value. While
validation passes, the resulting POST data still shows 'string2' as an
empty string.
I thought that changing and returning the cleaned data would do it, but
apparently not.

Thanks for responding. I'll have to look into using POST. The problem
with NOT requiring string2 is that I still can't change the value.
Instead of checking if it's not there, I check for an empty string:
if cleaned["string2"] == "":
cleaned["string2"] = string1
which means an empty string goes along with POST, not the value I set.

{% load %} tag in a base template can't be inherited?
Running Django v0.96.
Want to check to see if this behavior is normal. I have a base template
that uses {% load %}. I have another template that extends the base
template. The {% load %} tag doesn't seem to carry into the extended
template. In other words, it looks like I have to use {% load %} in
every single extended template, not just declare it once in the base.
To give a concrete example:
--base.html--
{% load mytags %}
{% mytitle "My Title Tag" %}
--base.html--
--derived.html--
{% extends "base.html" %}
{% mytitle "My Title Tag in the Derived" %}
--derived.html--
Using 'base.html' calls 'mytitle' just fine. Using 'derived.html' does
not.
On a related note, the docs say:
If you use {% extends %} in a template, it must be the first
template tag in that template. Template inheritance won’t work,
otherwise.
This isn't true unless {% load %} doesn't count as a template tag. My
derived templates work if I put {% extends %} first or {% load %} first.

Thanks for the info. At least I know I'm not missing something. It
does seem to interfere with DRY since I have to repeat {% load %} (in my
case, there are 2) in each child template.

I took the quote from the v0.96 doc

that's true, that's one reason why mod_python can't find
"mysite.settings".
I run Apache using virtual servers, so my ... stuff
is associated with a specific virtual server (in httpd-vhosts.conf). If
you don't, you can put it into the top-level httpd.conf file. Mine
looks like this:
SetHandler python-program
PythonHandler django.core.handlers.modpython
PythonInterpreter wise
PythonPath "['/home/adam/Src/WISE-2.0'] + sys.path"
SetEnv DJANGO_SETTINGS_MODULE WebSite.settings
SetEnv PYTHON_EGG_CACHE /tmp/.python-eggs
PythonDebug On
I have everything at http://my-server/wise2/ and under handled by
mod_python. The two main things here are PythonPath and
DJANGO_SETTINGS_MODULE.
Given your structure above, settings.py (along with views.py, urls.py,
and __init__.py) should be in the 'mysite' directory. Then PythonPath
would be set to point to the directory 'mysite' is in:
PythonPath "['/my/dir'] + sys.path"
In this case, your 'mysite' directory can be found at "/my/dir/mysite".
Then DJANGO_SETTINGS_MODULE would point to the settings file via the
Python import syntax:
SetEnv DJANGO_SETTINGS_MODULE mysite.settings
mod_python would find the settings.py file because it would be in the
'mysite' directory.

I set up to handle static content if running in DEBUG mode (i.e. theff
# Set up to server static files if running within the development
# environment
if settings.DEBUG == True:
urlpatterns += patterns('django.views.static',
(r'^(?P.*)$', "serve", {"document_root":
"/project/www/htdocs/WISE
",}),
)
This goes last in urls.py and will pick up anything not matched by a
real Django pattern match (i.e. everything that's NOT a Django page).
So if I have a URL like ", the
dev server will actually serve (given my example)
"/project/www/htdocs/WISE/img/icons/UnknownPerson.jpg" from the local
filesystem.

Having problems changing the default query set for Admin
Using Django v0.96 According to what I've been able to find, I can assign my own Manager to a Model. Setting up my default Manager would then affect the default query, which includes the one the Admin view would use. For example: class OrgManager(models.Manager): def get_query_set(self): qs = super(OrgManager, self).get_query_set() return qs.exclude(OR_Name = "N/A") # Organizations class Org(models.Model): # Org's name OR_Name = models.CharField( maxlength = 50, help_text = "Name of the organization" ) objects = OrgManager() def __str__(self): return self.OR_Name class Admin: pass The idea it to NOT show the "N/A" entry, but to show all the rest. I create OrgManager.get_query_set() to return everything except "N/A". I set Org.objects to use this manager, and since it's the only one set, it should also be the default. Running in the shell works as expected (Org.objects.all() shows all EXCEPT "N/A"). It doesn't look like the Admin view even uses the manager. I even put a print statement into get_query_set() to see it being called and it never was. Am I missing something? Can I affect the query the Admin view uses? -- Adam Stein @ Xerox Corporation Email: [EMAIL PROTECTED] Disclaimer: All views expressed here have been proved to be my own.

Trouble with STATIC_URL in v1.5.2
Maybe this is something well known. I'm using STATIC_URL in my templates. Worked perfectly in Django 1.4.x. Upgraded to v1.5.2. Now STATIC_URL ONLY works when the DEBUG setting is True. When set to False (For production), STATIC_URL is an empty string in the template. Anybody have any idea why this might be happening or what to look at? Everything that needs to be set for STATIC_URL is set, otherwise it wouldn't have worked in v1.4.x in the first place. -- Adam (a...@csh.rit.edu) -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Trouble with STATIC_URL in v1.5.2
Turns out that I had to use the new {% static %} template tag. It seems
that STATIC_URL is only set in the context for template use when in
DEBUG mode (didn't look in the code, but it appears that way).
{% static %} works for both development and production environments. It
was pretty simple for me to switch. All STATIC_ variables were already
set correctly. I just needed to add this to the top of my base template
file:
{% load static %}
{% get_static_prefix as STATIC_URL %}
and everything else remained the same.

I'm not using RequestContext(). The behavior must have changed between

Re: Did Ubuntu 14.04 or Linux Mint 17 break your Django project files?
IntegrityError is at the database level (not the OS). Shouldn't have anything to do with the OS specifically. Has the database you are using changed?

Re: What is *the* django 1.7 IDE which is opensource & multiplattform
Not sure what you are looking for in terms of Django template support. The only difference between pycharm community (free) and commercial in terms of Django support that I've noticed is that Django's development web server won't restart automatically when code changes in the community edition. Haven't used community edition since last year, but I seem to recall, I was still able to have a task to start Django's dev web server (in debug mode so I can trace through my code as you'd expect), so as long as I restarted that after making changes, things were fine.

By that, I mean, do you install your files somewhere else once you are done making changes to another server where it's "officially" used? I ask because you really don't want to be editing live files where "live" means what your customers (or yourself) are really using. I develop locally, then deploy to a remove server only when changes are done and tested. Therefore, my edit/run/debug cycle with PyCharm consists of running Django's web server (./manage.py runserver) on my local machine through PyCharm's debugger so that I can step through the code. I also have PyCharm set up to run various unit tests (also useful if I need to step through unit test code). I don't restart httpd, because that is running on the remove server and only needs restarting when my code is deployed. In the case of restarting Django's web server, PyCharm's professional version ($$$) has the ability to restart it for you if you have it running within PyCharm. For the community version, you have to restart it yourself which is as simple as clicking a "restart" button. If your files live somewhere else, you can mount the file system as you've mentioned. Performance might be better if the files were local, but that's true anytime you go across a mounted file system. Hopefully that answers your questions. -- Adam (a...@csh.rit.edu) -- You received this message because you are subscribed to the Google Groups "Django users" group.

While there are certainly lots of Django best practices, I think the use of a development environment and deployment would work equally well for any type of project, not just Django. In fact, anything I've ever worked on C, C++, Python/Django, Perl/CGI, etc., would all start in a local development environment first.

Looking for a full time Django/Python job (Rochester, NY area OR remote)
As I can't relocate, I'm looking for something either in the Rochester, NY area OR remote. I've been using Django for professional and personal use for about 6 years. Check out my LinkedIn page (www.linkedin.com/in/adamestein/ ) for more details about my skills and work history. A resume is available upon request. I'm currently using Django/Python for my own personal projects. You can see examples at http://stein.alwaysdata.net/. The 'Home Web Apps' is meant to keep track of my monthly bill payments. The 'Shop Owner Web Apps' is meant to keep track of inventory and sales. Just log in with the user name "guest" and password "guest" for either project. These are meant just for me so it's missing functionality that you would see in a commercial project, but it does provide an example of Django and JavaScript (specifically jQuery). Also, they are works in progress. Feel free to try out anything you want. The "guest" account is specifically there so I can show these projects to others. Other Python and/or Django examples can be found at https://github.com/adamestein/. My tic-tac-toe program is a command line program with an option (--humanstart) to allow the human to go first. All other projects were created by someone else, but I added functionality that I needed for home Django projects. You can contact me at 'a...@csh.rit.edu' or through my LinkedIn profile. -- Adam Stein (a...@csh.rit.edu) -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Storing images in a database using Django.
You can take a look at django-db-file-storage
https://readthedocs.org/projects/django-db-file-storage/
In my case, I was making something for myself and the hosting server
doesn't allow me access to any kind of file system, so I found this.

Re: Test fails when run in whole test suite - but not stand-alone?
When I've had that happen before, it's because some previous test
changed something (like a setting value or the site domain) that
influenced the test that failed. To narrow it down, I would run all the
tests up to and including the failed one. That should fail, then I
start taking out half the tests before. If the test still fails, I keep
cutting in half until I can determine which previous test is causing
issues. If, after cutting out tests, the problem test passes, then I
need to put back in what I took out since it was one of those.
Once I figure out which previous test it was, I can start removing the
individual tests to finally get to the code causing the problem.
Usually, it's a case that a test changed something and I just have to
add in the teardown function to restore the state of whatever was
changed.

Unfortunately, nothing easy comes to mind. My only thought was the possibility of putting your own wrapper around their tests. The idea being is that you call your wrapper which in turns loads the fixtures and calls their tests rather than having Django call their tests directly. This wrapper could be a unit test or be a derivative of the Django test runner. Don't know how feasible either is but I'm guessing neither would be trivial. Maybe I'm wrong, I didn't pursue the thought any more than having a wrapper of some kind. I was originally just going on your statements that fixtures weren't used in the tests because they weren't recommended (which is not really the case). Hope you figure something out. > Cheers > > Tom > > -- Adam (a...@csh.rit.edu) -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: circular imports error
Since you said 3 separate apps, I assume each of these classes are in a
separate file. However, you have the line:
from .models import Supplier
which would make it seem that Supplier is defined in the same file as
Shipment. Shipment should be in ".models" and if Supplier is also
defined in the same file, no need to import it. If it's defined in a
different file, then the import should reference another place, not
".models".
