Re: 'CSRF verification failed." from django.contrib.comments. can you help solve it? django 1.3

[brycenesbitt]

It works now that I have fully uninstalled pybbm.
Pybbm was incompatible with my app because it also extended the User
object (something apparently you can only do once?)

Re: access the state of a Model object prior to it's modification ?

[Jani Tiainen]

Probably you want to do that logic a slightly differently on a model level
(so rule would apply always when you save your model).

So you would actually override model save method.

Probably rule is something like this:

class MyPublicationModel(Model):
def save(...):  # I don't remember the signature
if self.is_published and not self.publication_date:
# Published previously unpublished - set the date
self.publication_date = date.today()
   elif not self.is_published and self.publication_date:
# Mark already published as unpublished - clear the date
self.publication_date = None

   super(self, MyPublicationModel).save(...)

Re: 'NoneType' object has no attribute 'datetime' bug?

[dobrysmak]

Thank's for help , i did this and now i've got this

This is strange because the shell import works fine but the server script

How to present a calculated field in a admin edit form.

[Erlend Dalen]

Hi,

I'm using Django 1.0 (beta_1) and have the following issue:
I have a method in a model that returns a calculated value and I would like 
this value to be displayed in the admin edit form related to that view.
I have no problem showing the field in the list_display, but if I add it to 
fields in the fields property in the ModelAdmin, I get an error message 
saying that there is no such key.

Is there an easy way of solving this?

Re: Query Distance from User

[tWoolie]

Just use Lat/Lon. You can fidget over which projection to use later as long 
as your data is good. (WGS84 is the best btw)

For geolocation, you can use the HTML5 Geolocation API that will use the 
person's browser to give you a location usually accurate to 200m (better if 
they're on a phone with gps), more than enough given your search radius of 
200miles.

For distance lookups, go with a simple bounding box algorithm (bounded by 
map edges, distance calc by pythagoras). Again exact positioning is NOT 
ESSENTIAL for your use case, especially on the 25mi scale.

If you ever find yourself needing better/more accurate position 
calculation. use postgis, but never install from source, use your distro's 
packages (it Just Works tm). Should be called 'postgresql-9.1-postgis' on 
most distros. do a search. make sure you have libproj and libgeos installed 
as well.

Re: 'NoneType' object has no attribute 'datetime' bug?

[tWoolie]

somehow, your global datetime variable is being clobbered with the value 
None. Find where that happens, and your bug will disappear.

Re: How to present a calculated field in a admin edit form.

[tWoolie]

What would it mean to django to have a formfield for a method anyway?

You need to override the edit page template for that model. 
or
You need to supply a custom form for the edit page that takes care of 
inserting and removing the calculated data on __init__ and clean

Nested querysets or a smarter template?

[Alex Strickland]

Hi all

I am new to Django and a bit lost at sea. I want to use Bootstrap and 
their accordion control. I have these models:


class Research_Category_Group(models.Model):
name = models.CharField(max_length=40)
class Meta:
ordering = ["name"]

class Research_Category(models.Model):
name = models.CharField(max_length=40)
group = models.ForeignKey(Research_Category_Group)
class Meta:
ordering = ["group","name"]

I want to see something like this (if you can picture it via ascii-art):


Bonds
US
Europe

Equities
Japan
Germany


but I get:


Bonds
US

Europe

Equities
Japan

Germany


My view is:

def add_document(request):
category_list = Research_Category.objects.all()
	return render_to_response("research/add_document.html", 
{"category_list": category_list}, 
context_instance=RequestContext(request))		


The template is:
  

  {% for category in category_list %}
  {% ifchanged category.group %}
  
		data-parent="#category_accordion" href="#{{ category.group }}">

  {{ category.group }}

  
  
  {% endifchanged %}

		{{ category.name 
}}


  {% ifchanged category.group %}
  
  {% endifchanged %}
  {% endfor %}

  


So I figure I need to have a nested queryset - which I can't figure how 
to do. If I managed it I'm not sure I would know how to use it in the 
template.


Or, I need to be cleverer in the template, I am using {% ifchanged 
category.group %}, but that is not enough to group the things within 
each accordion heading, as I don't know how to "delay" that trailing 
 properly.


Anyone able to help?

Write a request for help, and then you'll work it out pretty soon after:

  {{ group.name }}

Re: Use Django to implement my GUI!

[Eugène Ngontang]

Ok!

I think several times and solved the problem.

In fact I think the admin was waiting an address to build the http response
it self, not really a http response.

I remove the HttpResponse or HttpResponseRedirect method  from the return
statement, and it worked as I expected.

The wrong code line :
   *#return HttpResponseRedirect('10.136.37.19:8080%s/'
% reverse 'app.views.job_exec_user_error', args=(self.jobhistory_id,)))   *

The correct code line :
   #return (reverse('app.views.job_exec_user_error',
args=(self.jobhistory_id,)))

Now I'm dealing whith asyncronous communications.

Excluding items from a queryset

[Sithembewena Lloyd Dube]

Hi everyone,

I have a queryset of categories and would like to exclude categories with
no items associated. I am cycling through the queryset as follows, without
the desired result:

for cat in categories:
if cat.item_set.count() == 0:
categories.exclude(pk=cat.pk)

How can I remove those categories (please note, I do not intend to delete
them)?

Thanks.

Built-in filter "linebreaks" does not do what it says in the documentation

[Daniel Klein]

So the bog-standard built-in filter linebreaks is supposed to do the 
following:

"Replaces line breaks in plain text with appropriate HTML"

The doc string is:

 """Converts newlines into  and s."""

However, it doesn't do this at all. It neither replaces nor converts; 
instead it leaves linebreaks in place and ADDS html tags:

return u'\n\n'.join(paras)

I could write my own filter that simply returns join(paras), but there's 
got to be a better way, no? And shouldn't we try to make the documentation 
talk about what is actually happening?

Re: access the state of a Model object prior to it's modification ?

Yes, you are right, but you are clearing the date, the thing
is that I don't want to clear it. That's why I thought of having
an attribute in the model that does not render in the form,
that would allow me to keep the previous state unchanged
and use that in my logic.

 Hi,

 Is there a way to access the state of a Model object prior to it's
 modification through a form ?
 Kind of a nasty question :S, let me explain.

 The thing is that if i use the save_model hook and the user modifies
 the model through the form,
 the obj parameter that I receive has already all the modifications
 loaded, so if  I have, let's say,
 a boolean attribute called "published"  and the user clicked published
 then :

 obj.published == True

 Is there a way to know which was the state of the model, in this case
 the state of obj.published,
 before the user clicked on the save button on the admin form ? or
 should I use a second model
 attribute and hide it on the form to keep the previous state ? is there
 a "Django" way to do this ?

 It's my first post, be gentle :P

 Thanks !

I would check a few things, first :

What smtp server are you using ?
Did you configured your django app to use the SMTP server?, I think you
need to add some SMTP_ vars to your settings.py,
because otherwise you will end up using sendmail (if it's linux) and it
might be shutoff for security reasons.

If you have an SMTP server in your hosting access it using TELNET and try
to send an email through the CLI interface
to check that it works correctly.

Hope it helps.

Re: satchmo and django-admin-tools

[Tomas Neme]

Yes, you'll need to get your hands dirty, and merge the two admin
templates, since both apps redefine templates/admin/index.html and
some other templates.

The best approach, I think, is just use django-admin-tools' templates
and create custom dashboard/modules to duplicate satchmo's templates'
behavior

Re: Why am I getting an error when send e-mail from hosting?

[Andrejus]

Nicolas, thanks for help.

I'm glad and proud to state I've discovered the cause of the problem myself 
- the problem was SMTP (or maybe the recipient's side) on hosting has been 
configured to reject any message without sender's address. Using send_mail 
with specifying sender explicitly solved my problem.

Progress monitoring using Django model is not syncronized (One writer and multiple readers)

[Wei An]

I am implementing a progress monitoring function using Django. However, I 
cannot get the updated value in the front end.

A Django management command is executed by popen to keep updating the 
progress of the model webscan. Scan is a Django model and progress_info is 
an attribute of the model which is saved in database. The code is as 
follows:

d = 10
while (d) :
time.sleep(10)
try:
isBusy = server.call("framework.busy?")
logging.debug(isBusy)
if isBusy.strip() == 'true':
progress = webscan.progress
webscan.progress_info = progress
webscan.save()
logging.debug("%s"%progress)
else:
d = 0
except Exception as e:
logging.debug("In an exception when calling busy. 
Exception: %s and Type %s"%(e, type(e)))
d -= 1

In the front-end, I make an ajax call to get the value of progress_info. 
The handler simply get the value of webscan.progress_infoand returns it to 
the front-end. The code is as follows:

@property
def get_progress(self):
return self.progress_info

Using the GUI of the DB, I can see that the value of progress_info is kept 
updated. However, the ajax call keeps returning 0 to the front-end until 
the command finishes (0 is the initial value ofprogress_info).

I guess it is because of the locking mechanism of DB or Django but do not 
fully understand why. Could anyone help me with it? Thanks a lot~

Is Tutorial / Part 4 wrong? (or is it me?)

[Bill Torcaso]

Django is great, and the tutorial is great.  I'm having a problem at the 
very end of tutorial-4.

I try to use generic views, and I get an error when I Redirect from the 
POST request in vote() to the Results page.  Details below.

The tutorial code says to put this in my urls.py:

url(r'^(?P\d+)/results/$',
DetailView.as_view(
model=Poll,
template_name='polls/results.html')
,name="poll_results" 
),

And this in my views.py:

 from django.shortcuts import get_object_or_404, render_to_response
from django.http import HttpResponseRedirect, HttpResponse
from django.core.urlresolvers import reverse
from django.template import RequestContext
from polls.models import Choice, Poll


def vote(request, poll_id):
p = get_object_or_404(Poll, pk=poll_id)
try:
selected_choice = p.choice_set.get(pk=request.POST['choice'])
except (KeyError, Choice.DoesNotExist):
# Redisplay the poll voting form.
return render_to_response('polls/detail.html', {
'poll': p,
'error_message': "You didn't select a choice.",
}, context_instance=RequestContext(request))
else:   
selected_choice.votes += 1

Re: Is Tutorial / Part 4 wrong? (or is it me?)

[Tomas Neme]

It's the second time this issue appears in the list in two weeks, maybe
it's time to recheck the tutorial?

There's no "polls" in your results' url, doesn't the tutorial say you
should have two urls file? one in project/urls.py and another one in
polls/urls.py ?

the polls-specific urls shouldn't start with "^polls/" and be in
polls/urls.py, and in project/urls.py there should be a line with

url(r'^polls/', include('polls.urls')),

The problem you've found isn't related to access to the relationship model
from template but that you aren't using the right names to access them.

Reading
https://docs.djangoproject.com/en/1.4/ref/models/fields/#manytomanyfield
and
https://docs.djangoproject.com/en/1.4/topics/db/models/#intermediary-manytomany
will be of great help.

Re: satchmo and django-admin-tools

[Tomas Neme]

> I thought they extended the templates instead of trying to replace

they don't replace everything. But the admin site's index template is
called 'admin/index.html', so it's not easy to extend them. They DO
extend admin/base.html.


This is my dashboard.py file, where I create a module that emulates
satchmo's template additions.

https://gist.github.com/3124534

There's a couple of things that are MY PREFERENCES, so it might not
all be to your liking, please do try to read, understand, and modify
as you like.

with this, I just use dashboards' admin/index.html template

Django Unit Tests Missing Database Columns

[Simon]

I created a unit test on Django to create a user account and send a 
verification e-mail. The user is created, but the e-mail fails to send. The 
e-mail's default contents are supposed to be created as a field in the user 
when a user is created, but for some reason, Django is claiming -

DatabaseError: no such column: app_userprofile.default_email_header

It works fine when the account is created manually, though for some reason 
it fails to create that column in the database when done from a unit test. 
Any suggestions for fixing this?

Re: Django in MovablePython

[Michael Palumbo]

Hi,

I have been recently concerned about getting a portable Django development 
environment as well. I wanted it to work on any computers without 
installing anything.
I could get it to work, I can now carry my environment and projects on a 
USB stick. :)
I assume it is a bit late for your case now but maybe it will help someone 
else.
I made a tutorial on my blog:
http://webdevon.com/setting-up-a-django-development-environment-from-scratch-on-windows/
 

Feel free to leave comment and/or send me your feedback to improve my 
"homemade" solution.
Also, updating the wiki might be nice for next people looking for it? What 
do you think?

Michael

Re: satchmo and django-admin-tools

[Avraham Serour]

thanks for sharing, I'll try to understand it.

where should I put this file? inside localsite?

what admin template are you talking about? the admin tools or the plain
admin?

I thought of using the admin tools templates and building from that, but
all I got was noReverseMatch erros, looks like the INSTALLED_APPS order is
significative and I don't understand it well.

how can I configure it to ignore the satchmo admin templates?

btw, could I make all this work with grappelli? it seems I could enjoy some
of the image uploading and wysiwyg editor

thanks
avraham

Re: Excluding items from a queryset

You can use an annotation:

categories.objects.annotate(Count(item)).exclude(item__count=0)

What this does is add a temporary attribute on each category 
object named `item__count', then you can exclude based on that 
attribute.

well, I should probably just point you to this:
http://django-admin-tools.readthedocs.org/en/latest/index.html

and specifically this:
http://django-admin-tools.readthedocs.org/en/latest/quickstart.html

You probably didn't add dashboard to INSTALLED_APPS and you're
probably missing the urls as well.

> how can I configure it to ignore the satchmo admin templates?

and some of django's documentation as well..
https://docs.djangoproject.com/en/dev/ref/templates/api/#loading-templates

The short version is, usually, you put under
yourproject/templates/admin/index.html whatever template you want to
be used, but do go and read those docs

you can most probably make everything work with everything, I don't
know what grappelli is, bear in mind you might need to dig deep in the
admin templates to make javascript (specially jquery) play nice with
every app you use

Re: ForeignKey problem

[Kurtis Mullins]

I'd suggest taking a step back from the data structure of your application,
decide what you want to do with your data, and then take another stab at
it.

If you have more questions, I'd recommend posting your questions using your
application's real domain instead of continuing to use "similar" ideas.

Good luck!

how forms.py works

Querysets are always cloned on calling a method, so the right syntax
is:
categories = categories.exclude(pk=cat.pk).
For efficiency reasons you might want to collect all the pks into a
list, and then after the loop do one:
categories = categories.exclude(pk__in=pk_list)

The queryset cloning can be expensive if you do a lot of operations.

Of course, the annotation way given downthread is likely to be the
most effective way to do this.

I don't accept your argument that the documentation is incorrect (or
that it's significantly misleading).

If you have plain text with newlines, you will usually want those
newlines preserved in rendered HTML. The way you do that -- the
"appropriate HTML" is to use  and  elements.

The implementation splits on newline characters, inserts the required
 and  elements -- and then joins with newlines to preserve
human readability of the output HTML. Newlines are a valid (if
ignored) part of the HTML spec; the newlines in the original markup
have therefore been "replaced" with the "appropriate HTML'.

If you can think of a better phrasing, we're always open to
suggestions. The current description has served us well for several
years, but that doesn't mean we're not willing to improve on it.

As for your actual problem: I'm not sure exactly what you're trying to
achieve -- i.e., why a strict join(paras) is an important operation to
you. Newlines are interpreted as whitespace in HTML, there's no
difference between text with newlines, and text without newlines
(other than human readability of the output).

If you're generating something other than HTML, then you're going to
need to build your own set of template filters; Django's builtin tags
are very much focussed at generating HTML.

Either way, a strict "join" filter isn't that complex -- maybe half a
dozen lines of code all up. If you truly need a strict join(), then
writing your own tag *is* the better way, in this case.

Yours,
Russ Magee %-)

django on shared hosting

[Jarrett Chisholm]

Hi all,

I'm trying to setup django on greengeeks (shared hosting).

I've setup flup and django and a small app.  I've also created my cgi file 
(mysite.cgi) that runs from my cgi-bin directory.  I originally setup my 
.htaccess file as well, but it seems to redirect fine without any changes 
to .htaccess (running with the changes to .htaccess didn't seem to help...I 
dunno, maybe the .htaccess stuff I was entering is wrong, I don't know)...

>From my browser, I point to my django site, and get a 500 server error.

When I run 'python mysite.cgi' from the console (on the server) I get all 
of the expected django HTML getting printed...

When I change the mysite.cgi file and add :
print "Content-type: text/html\n\n"
print 'HI MOM'

and then point my browser to my site, it outputs 'HI MOM' on the screen 
(but nothing else)...

SO, mysite.cgi is being called!  Unfortunately, the django HTML is not 
being captured (or something) and returned to the browser (...).

I'm not really sure how to proceed from here...how do I get the HTML that 
django prints to the browser?

Here's my mysite.cgi

import sys, os

# Add a custom Python path.
sys.path.insert(0, "/home/icebreak/bin/python")
sys.path.append("/home/icebreak/lib/python2.4/site-packages")
sys.path.append("/home/icebreak/bin")
sys.path.append("/home/icebreak/django_projects/icebreak")

# Switch to the directory of your project. (Optional.)
os.chdir("/home/icebreak/django_projects/icebreak/mysite")

# Set the DJANGO_SETTINGS_MODULE environment variable.
os.environ['DJANGO_SETTINGS_MODULE'] = "mysite.settings"

from django.core.servers.fastcgi import runfastcgi

#print "Content-type: text/html\n\n"
#print 'wtfd'
runfastcgi(method="threaded", daemonize="false", 
outlog="/home/icebreak/django_out.log", 
errlog="/home/icebreak/django_err.log")


I've got a question on stack overflow, but not much luck 
(http://stackoverflow.com/questions/11493803/django-on-shared-hosting-greengeeks).

I appreciate any help you guys can provide!!

Thanks!

Any free cloud database hosting ?

[surya]

I am building a facebook application where I have to use database models 
(very small size ~ 1MB - 2MB). Is there any good cloud db storage website 
for hosting the database??

I looked around Amazon Web Services, it has really great offers but "I 
don't have credit card" :(  

I thought of using Google Cloud but I need to use "django-no rel". As there 
are some external lib involved in my project which create tables, I don't 
think I can tweak them successfully!

So, how exactly I should host the database??

-- Actually, I am using fandjango, facepy libs which need a database

Re: Query Distance from User

So wait,

Does UTM have to do with the timezones in the USA? Do some of the lines match 
to tomezone lines? You also never really answered my question before. Sure it 
sounds like you know what UTM is but I sure dont and thats all youre talking 
about.

If this is about the timezones or whatever then yes I can sort of imagine the 
issue youre talking about. I know what pythagoreans theorem is im a math guy 
but i cant quite pick how it applies to any of what we are talking about. Are 
you saying i need it to be able to calculate the circle and distances from a 
point in a 25 mile radius so x^2 +y^2 = 25 mi ^2?

Sorry if i seem slow. Still new to this.

Re: Query Distance from User

[JJ Zolper]

 Just use Lat/Lon. You can fidget over which ojection to use later as long as 
your data is good. (WGS84 is the best btw)

I agree lat long sounds beautiful to me! Well thats good.


For geolocation, you can use the HTML5 Geolocation API that will use the 
person's browser to give you a location usually accurate to 200m (better if 
they're on a phone with gps), more than enough given your search radius of 
200miles.

Oh okay ill keep that in mind in case i make a iphone app cause right now i 
like the idea of lat long.

For distance lookups, go with a simple bounding box algorithm (bounded by map 
edges, distance calc by pythagoras). Again exact positioning is NOT ESSENTIAL 
for your use case, especially on the 25mi scale.

What about a circle? Use lat long equated to a city or address and do a circle 
with that point in lat long and find all the data within the circle?

If you ever find yourself needing better/more accurate position calculation. 
use postgis, but never install from source, use your distro's packages (it Just 
Works tm). Should be called 'postgresql-9.1-postgis' on most distros. do a 
search. make sure you have libproj and libgeos installed as well.

Is "it just works" a programming catch phrase? Haha. Yes the distros this next 
time not the other way.

Can't use admin with apache

[Matt Smith]

Background: I work on my projects using apache2 on my desktop machine, 
then just rsync across to the actual server (also apache2), that way I 
thought I could avoid the hassle of having things work with the dev 
server, but not with apache. Not so. Today I've discovered that the 
admin works under the dev server, but not with my apache setup. I 
replicated this using a brand new helloWorld project. I've searched the 
archives, the docs, the book, also ordinary web search. Found some 
people had similar problems and fixed it with apache Alias directives 
pointing ADMIN_MEDIA_PREFIX to DJANGO_SRC/contrib/admin/media but this 
didn't work for me. I get a 500 internal server error, regardless of DEBUG.


Appreciate any help with this.

Re: Any free cloud database hosting ?

[surya]

Hi Alex,

Actually I am perfectly aware of Heroku. The point is, when I tried to 
install Postgre add-on in it, its asking to "verify" my account. i.e., to 
provide credit card details.

Thats the problem...

So I looked around OpenShift and I think most of it is for free. can you 
tell me more on it? How it works (Its up-time, speed etc)..

PS: do we really need to provide credit card details for Heroku to use db 
?..

 I am building a facebook application where I have to use database

 I looked around Amazon Web Services, it has really great offers but "I 
 don't have credit card" :(  

 I thought of using Google Cloud but I need to use "django-no rel". As 
 there are some external lib involved in my project which create tables, I 
 don't think I can tweak them successfully!

 So, how exactly I should host the database??

Django TypeError

[Sandeep kaur]

I want to have different views for my application for different types
of users. For this I have this code for my views.py file :

def index1(request):
u = User.objects.all()
if u.is_staff ==1 and u.is_active == 1 and u.is_superuser == 1:
return render_to_response('tcc11_12/index1.html',
context_instance=RequestContext(request))
elif u.is_staff == 1 and u.is_active == 1 and u.is_superuser == 0:
return render_to_response('tcc11_12/index2.html',
context_instance=RequestContext(request))
else:
return render_to_response('index3.html',
context_instance=RequestContext(request))

But it gives TypeError as :
 "cannot convert dictionary update sequence element #0 to a sequence"

Is there anything wrong in above code?

Re: Django TypeError

 u = User.objects.all()
u is not a user.
