A BooleanField might be better then.

"__magic_methods__" are here to support operators (or operator-like)
implementation, and except for a very few corner cases you should not
call them directly. So here you want "len(text)", not
"text.__len__()".

Also note that the parens are the "call operator", so "text.__len__"
will eval to the "__len__" method object itself (remember that in
Python everythin is an object, including classes, functions and
methods), not to the result of calling this method.

And finally, in Python, empty sequences (at least for the builtin
sequence types), empty dicts, empty strings, numeric zero (int, float
etc) and the None object all have a false value in a boolean context
(FWIW, True and False and the bool type are late additions to the
language). So the pythonic way to test for an empty string is just :

if not txt:
print "txt is empty"

I'd still use a BooleanField here as far as I'm concerned, but when it
comes to multiple choices, here's how I do:


class X(models.Model):
USE_YES = 'Y'
USE_NO = 'N'
USE_CHOICES = (
(USE_YES, u"Yes"),
(USE_NO, u"No"),
)

   use_txt = models.CharField(
   u"Use text",
   max_length=1,
   choices=USE_CHOICES,
   default=""
   )


then I can test the value using the class pseudo-constants, ie:


x = X.objects.get(pk=1)
if x.use_txt == x.USE_YES:
   pass

would be a bit better (or at least a bit less worse ) this way:

if not txt and use_txt == TO_USE[0][0]:

But that's still not something I'd be happy with. My above solution
would make it a bit more readable:

if use_txt == X.USE_YES and not txt:

Indeed. And not even consistant - if you insist on using
__magic_methods__ instead of the operators, at least go all the way:

TO_USE.__getitem__(0).__getitem__(0)

?-)

Sorry, just kidding

Re: template error in html forms

[TANYA]

thanks, the template error went away but adding this code to  views.py
still gives  search error.

def search(request):
error = False
if 'q' in request.GET:
q = request.GET['q']
if not q:
error = True
else:
books = Book.objects.filter(title__icontains=q)
return render_to_response('search_results.html',
{'books': books, 'query': q})
return render_to_response('search_form.html',
{'error': error})

Which views.py should i add that code to? -- mysite/views.py OR
mysite/books/views.py ??
Should every folder in mysite have the path set? I mean to ask if I should
have "os.path.join(PROJECT_PATH, 'models')," for databse folder and
"os.path.join(PROJECT_PATH, 'picture')," for my jpg images and "
os.path.join(PROJECT_PATH, 'test'), for the test files and
os.path.join(PROJECT_PATH, 'documentation'), for documentation. Maybe this
is a silly question but its not very clear what to do for the path. thanks.

 This MUST be an absolute path. And if your modifying this setting for the

create users from /etc/passwd?

[Tim]

I'm running Django 1.3.1 on FreeBSD + Apache2.2 inside an intranet. 

I do not grok authentication, so here is my problem and a question about 
how I can solve it (maybe).
What I need is the name of the user who hits the application. I don't care 
about the password, I just need to know who they are. I've been unable to 
get the REMOTE_USER from Apache, mainly because I think Apache doesn't know 
it either (no authentication is used on the httpd.conf).

I thought (here's my maybe solution) I might create a bunch of users in 
Django by parsing the /etc/passwd database. Then at least each user would 
have the same username/password they use to login to the network.

Is that possible? Is there a better way to get the username?
thanks,
--Tim

Re: ImportError at /accounts/login/

[akaariai]

I don't think we are able to help you without more detail. The browser
window should contain the lines which caused the error (when run with
settings.DEBUG=True). Include those lines, and it is more likely that
you get an answer. Including full stack trace of the ImportError is
even better.

south create_table doesn't work

[Alessandro Candini]

I'm trying to use django-south-0.7.3 API's to create a table, following 
this: http://south.aeracode.org/docs/databaseapi.html#accessing-the-api


This is my code:
from south.db import dbs
dbs['lc'].create_table('test', [
('id', models.AutoField(primary_key=True)),
('name', models.CharField(max_length=255)),
])

The problem is that I do not get any error, but in the lc database, no 
table appears.

Where is the issue?

Thanks in advance

Re: create users from /etc/passwd?

[Furbee]

Hi Tim,

I'm not totally sure, but I don't think this will work. You could parse the
passwd file to get the usernames, but the passwords are encrypted. Since
you don't have the system's decryption key, you would not be able to
determine the password. If you just used what is in /etc/shadow it would
not match the password that the users enter when they try to authenticate
in Django.

I would suggest using Django's built-in authentication system. Then when a
user goes to your site, and enters their credentials, you will be able to
access the user information in the view with request.user (assuming
"request" is your view's first parameter name).

Django's documentation is a lifesaver, here's setting up User
Authentication:
https://docs.djangoproject.com/en/1.3/topics/auth/

Here's accessing session information when a user is logged in.
https://docs.djangoproject.com/en/1.3/topics/http/sessions/

Finally, you can use the decorator @login_required for views that require
authentication. However, I found it easier for many applications that use
site-wide authentication (usually the case with intranet development) to
use middleware to require login for every page. I implemented something
similar to this and it works perfectly.:
http://onecreativeblog.com/post/59051248/django-login-required-middleware

You're want to study up on how middleware works, here:
https://docs.djangoproject.com/en/1.3/topics/http/middleware/


Good Luck,

Furbee

base.css 404ing on Django 1.4a1

[Alec Taylor]

Trunk version cannot load Admin CSS.

First I tried setting the ADMIN_MEDIA_PREFIX to MEDIA_PREFIX, when
that didn't work I tried manual replacing. Yes, I know it has been
depreciated and that the css are stored in
django\django\contrib\admin\static\admin\css, however it did not work
when omitted so I placed that \static\admin\ folder as a subdirectory
of my regular static directory.

ADMIN_MEDIA_PREFIX is now set to: '/static/admin/' in settings.py.

This partially worked, the top of my admin pages now look like this:



So dashboard.css is loading fine now, it's just base.css which isn't.

How should I go about getting that base.css link to not 404, or
*actually* changing that ADMIN_MEDIA_PREFIX?

Thanks for all suggestions,

Alec Taylor

Re: Newbie django/python with C++ background wants enums

[ajohnston]

I would probably do it Bruno's way, since it is more explicit, but
just so you know, there are some enumeration tools in Python. Just not
an 'enum' type:

>>> base_choices = ['No', 'Yes'] <-- transform this any way you want:

>>> choices = list(enumerate(base_choices))
>>> choices
[(0, 'No'), (1, 'Yes')] <-- can be used for 'choices' parameter in
BooleanField

>>> use_txt_choices = {v:k for k,v in enumerate(base_choices)}
>>> use_txt_choices
{'Yes': 1, 'No': 0} <-- can be used in 'clean' method:

if len(txt) == 0 and use_txt==use_txt_choices['Yes']:
pass

If the values have to be boolean instead of ints, you can:
>>> txt_choices = [(True if i else False, j) for i,j in enumerate(base_choices)]
>>> txt_choices
[(False, 'No'), (True, 'Yes')]

>>> lookup_choices = {v:True if k else False for k,v in enumerate(base_choices)}
>>> lookup_choices
{'Yes': True, 'No': False}

Two quick pointers:
  - You probably want to use the reverse method and the url template
tag. Django documentation will tell you more about these.
  - Why does the login/logout views take optional poll_id argument
which is then not used. You should have the login and logout views
only once defined in your urls.py, that is, not also under /id/login.

[django-taggit] Recording additional tagging metadata with the admin

[Lorenzo Franceschini]

Hi, I have a question about ``django-taggit`` and the admin site.

I have written a custom intermediate model [1] for storing additional 
tagging metadata, i.e. the user doing the tagging and when the tagging 
happen:


class TaggedItem(GenericTaggedItemBase, TaggedItemBase):
tagger = models.ForeignKey(User, null=True, blank=True, editable=False)
tagging_time = models.DateTimeField(null=True, auto_now_add=True)

Then, I made a model taggable:

class Foo(models.Model):
# field defs

   tags = TaggableManager(through=TaggedItem, blank=True)

Now when a ``Foo`` model instance is created/changed, I would like those 
additional tagging metadata to be filled with ``request.user`` and the 
current time.


My question is: how can I achieve this behaviour ? I suppose I have to 
hook someway in the admin, but I don't know way.


Thanks in advance for any answers.

Re: django-mptt compared w/ django-treebeard

[creecode]

Hello Aljosa,

I wouldn't assume that just because something hasn't been updated for 
awhile that it isn't good.  It simply could be that the app does what it 
needs to and there hasn't been a reason to change it.  You might want to 
contact the app authors and ask if their projects are actively maintained.

Toodle-looo.

Re: Newbie django/python with C++ background wants enums

[ajohnston]

I'm straying a bit off-topic here, but I forgot to mention that other
way I've seen people do 'enum' in Python is:

>>> class Colors(object):
... RED, GREEN, BLUE = range(3)
...
>>> c = Colors()
>>> c.RED
0
>>> c.BLUE
2
>>> c.GREEN
1

Not sure this helps much in this particular case though.

Re: create users from /etc/passwd?

[Tim]

Thanks for all this great information. Thorsten, I do have hope that 'pam' 
will solve the problem, but if I get nowhere with that, Furbee's links and 
info will help me go further; I just didn't want the user to have to sign 
on twice when I don't really care about authentication, just user 
identification.  In any case, I'm reading those docs now, and the blog 
article.

David, I wish I could do this via the LDAP set up but as far as I can tell 
there isn't one.

thanks again!

register.html. So the register form is included on the home page but i
want to keep all registration specific handling seperate thats why i
have put it in its own app. So on the homepage the included
register.html page that has a form with a url to post to say /
register/ where it will head off to the register app and register the
user and redirect elsewhere or return back to home.html with the form
errors. So my question is that when it posts off to /register/ my
views in the register app would need to render_to_response home.html
to get back to where it was sent from in order to get the form errors
which has now got a new url in the url bar so instead of /home/ it
says /register/ but still displaying the home page which i think is
silly. Does anyone have any input on this or would it be better to use
an ajax request in this situation so the url doesnt have to change and
i dont have 2 views rendering the same page.?

thanks.

Entering Text into a Database

[ds39]

Hello Everyone,

I've just started web programming and using Django, and I'm still not
sure how to enter text into a database via a page. From everything
I've read, the suggestion seems to be that a ModelForm should be used.
I've tried to implement this on a simple example model, but I'm sure
I'm doing most of this wrong. Is there any page, outside of the
official documentation, that gives an example from beginning to end
regarding how to save ModelForms in your database using views.py
rather than the shell (including sample URLs) ? Also, how would I
access the entered text via the shell to determine if it was saved ?

Thank you

The Django 1.4 roadmap

Before the final Django 1.4 release, several other preview/development
releases will be made available. The current schedule consists of at
least the following:

* Week of January 30, 2012: First Django 1.4 beta release; final
feature freeze for Django 1.4.

* Week of February 27, 2012: First Django 1.4 release candidate;
string freeze for translations.

* Week of March 5, 2012: Django 1.4 final release.

If necessary, additional alpha, beta or release-candidate packages
will be issued prior to the final 1.4 release. Django 1.4 will be
released approximately one week after the final release candidate.

Thanks Anssi!

Here is my solution, I wonder if you could just tell me if you think
there's a major problem with it.

In simplistic terms, the goal is "whenever a model from wxdatabase is
accessed, route the query to the database specified in the user's
organization's field".

It consists of a piece of django middleware and a db_router.

I guess my main question is: am I using threading.local() correctly?

Cheers!

Tom

You can.

If you accept that users will have to authenticate in your Django app 
then if you use ldap you won't have to worry about passwords at all. 
They will enter the same username and password they usually do when they 
power up their workstations.


I have used Peter Herndon's django-ldap-groups very successfully to do 
just that. It will create a new user including any ldap groups you set 
up for Django based entirely on successful ldap authentication. It will 
bring whatever ldap info across to Django that you require.

problem installing PIL

[NENAD CIKIC]

I came across this problem (the problem is that i can not install PIL on my 
windows 7 64 bit machine) when I have tried to use ImageField. I have first 
tried to use C++ Express but I came across 
http://bugs.python.org/issue7511. Then I have tried to use mingw and cygwin 
but the gcc complied about some parameters the setup was passing.
I know I can use just the Filefield, and i will do it; I am now just 
curious how can i install this PIL on windows machine?
I have also tried the pillow, but it blocks with the same issue. Is there 
an alternative, since I have noticed the last release is from 2 years ago, 
but then again from django docs it says I should have it if i want to use 
ImageField?

I must warn you that I don't know too much about db routers.

I think here you should make sure you always also clear the
wx_database_label variable, so that it won't be left pointing to a
user's DB in any case. That is, you would need a finally block, and a
process_response method.

Also, I think you are going to generate some more queries than needed
by the user.profile.organization.database.label. If I guess correctly,
that is going to be 5 DB calls for each request. .select_related()
could be handy here...

Did you do the tutorial[1]?. Be sure to do all four parts. After that
the examples in the ModelForms documentation[2] should make sense. If
not, ask specific questions about what is not working the way you
think it should. Good luck.

Re: Entering Text into a Database

[Python_Junkie]

Not sure if this will help, but I have diverted from the standard
method of database updates taught in the tutorial.

I take a more traditional sql methodology

for example in any view that I am using.

I collect the data elements via a request
and then build a sql statement

for example

(The exact syntax may be a little off.)

var_1=request.post(name)

var_2=...etc

insert into table 1(col_1,col_2) values ('var_1,var_2)

commit


Let me know if this helps and I can update the syntax to be more
precise.

auth groups puzzle

[Mike Dewhirst]

I want to use the built-in auth_groups permissions system in a 
many-to-many sense but can't quite figure it out for my use case. Any 
help will be appreciated.


The use case is: users have different types of access (r/o, r/w or 
admin) to different companies. Any single user can have r/o access to 
company-1, r/w access to company-2 and admin access to company-3 and so 
on. Any company can have relationships with many users each of whom will 
have one of the r/o, r/w or admin group permissions.


So there has to be a many-to-many relationship between user and company 
and the group needs to be specified in that relationship table rather 
than in the auth_user_groups table - where it currently sits.


How do I invoke a different set of permissions depending on the name of 
the group established in the user-company relationship table when a user 
is accessing that company's data?


A side question is how do I remove the displayed Groups in the Django 
Admin auth/user display?


Thanks

Mike

Re: Entering Text into a Database

[Mario Gudelj]

Hey dude,

Let's say you have some model with fields defined. It's called Business.
Looks something like this:

class Business(models.Model):
id = models.AutoField(primary_key=True)
name = models.CharField("Business Name", max_length=NAME, blank=False)

You create a ModelForm like this:

class BusinessDetailsForm(forms.ModelForm):
class Meta:
model = Business

In your view you have a method that captures the POST and saves it inside
the model:

def save_business_details(request):
if request.POST:
form = BusinessDetailsForm(request.POST)
if form.is_valid():
form.save()
return
HttpResponseRedirect(reverse("your_app.views.some_view_when_submission_is_successful",
args=[]))
else:
here you pass back the form or whatever
return render_to_response(and render that whatever)

So, form.save() will save the details.

I hope that helps!
