Re: ForeignKey to_field problem

[bhuztez]

Without to_field, it works. But, setting to_field to name, you can
simply type name in the input field of django admin, instead of id.

I am just wondering why the api behaves differently if to_field is set
to another field other than id.

We create like this:
>>> pet = Pet.objects.create(owner=person, name='B')
But, we have to get like this:
>>> pet = Pet.objects.get(owner=person.name, name='B')

Hence, we cannot get_or_create

Re: Django on Mac OS X

[Daniel França]

Hi, thanks, I didn't know this werkzeug debuger.
Now I can see exactly where it raises the error and can print the variables
values, here's the output with some values:

File
"/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/db/backends/sqlite3/base.py",
line *200*, in execute

return Database.Cursor.execute(self, query, params)

[console ready]
>>> print params
(1, , u'pt-br')
>>> print self

>>> print query
INSERT INTO "account_account" ("user_id", "timezone", "language")
VALUES (?, ?, ?)
>>> print params[1]
America/Sao_Paulo
>>> print params[0]
1
>>> print params[2]
pt-br


Any idea?

Re: ForeignKey to_field problem

[Renne Rocha]

  Try defining the pet model like this:

class Pet(models.Model):
   owner = models.ForeignKey(Person)
   name = models.CharField(max_length=30)

Than it will work.

filtering related object in template

[Martin Tiršel]

Hello,

I can do:

{% for image in gallery.image_set.all %}
...
{% endfor %}

but my image model has:
is_thumbnail = models.BooleanField()

and I want to limit displaying only these images which have  
is_thumbnail=True. I can create a method on the image model, which returns  
images I want to, but is it possible in template too?


Thanks,
Martin

How to pass session to form and customize error_message value based on session variable

[ydjango]

I have

class NewEventForm(ModelForm):
Event_name = forms.CharField(label='Event
Name*',widget=forms.TextInput(attrs={'size':'82','maxlength':'100','tabindex':'1'}),error_messages={'required':'!
You must enter Event Name.'})
description=forms.CharField(label='Event Description*',
widget=TinyMCE(attrs={'cols': 90, 'rows':
20,'tabindex':'2'}),error_messages={'required':'! You must enter a
Description.'})

 class Meta:
model= Event

I want to
1)  Pass  session to the form
2) Customize
   a)  message text as in "error_messages={'required':'! You must
enter Event Name.'}"  based on certain settings in session.
   b) value of label based on certain session settings as in -
label='Event Name*',

and I want to do it for all the forms in my application. What would
the best and least repetitive way to do it. I have around 20 forms.

ManyToManyField limiting choices

[Martin Tiršel]

Hello,

I have a gallery model and an image model. First, I create some galleries,  
then I insert images into them. But now, I want to add multiple thumbnails  
feature for galleries (thumbnails representing the gallery, not thumbnails  
for images inside gallery), so I added ManyToManyField and I can select  
some images, which will be used as thumbnails. But is there a way, how can  
I limit these images only to images belonging to the currently editing  
gallery?


There is the limit_choices_to option, but I would need to point to 'self',  
what is not possible on this place. Second problem would be that I have to  
create gallery first, then insert images and then select thumbnails, so  
there is another problem, that if there would be a solution in limiting  
the image list, I can not use it in create gallery page in admin.


What is the best way to solve this problem?

Thanks,
Martin

Re: Django on Mac OS X

[Xavier Ordoquy]

Please, install django_extentions, werkzeug debuger and try to see what exactly 
where the issue is with the runserver_plus command (in browser debugger so 
you'll get the variables that are missing here.
Most probably, your timezone field causes the issue.

Have you looked at the headers of a pair of messages to see if you are
receiving them on different email addresses?  If so, just unsubscribe with
one of them.  If not, well, you need further help!

Re: custom vocabularies vs translation

[cootetom]

Using the language files is the solution here. Even if your site only
supports the English language, it still means that you can have .po
files for just English. Once you understand how it all hangs together
you'll be away.

http://docs.djangoproject.com/en/1.1/topics/i18n/#topics-i18n

I have a site that is just English but we allow the client to choose
what text they want to use. The text in templates can be descriptions,
for example you could type "Home page welcome message" in a template
and mark it for translation. Then in the English .po file you can see
what the text is used for and input the correct English for it.

Re: Translation

[cootetom]

It's all there, you just need to implement it.
http://docs.djangoproject.com/en/1.1/topics/i18n/#topics-i18n

If you'd like a tool to help edit the translation files then check out
one of the following:
http://poedit.tomcoote.co.uk/
http://code.google.com/p/django-rosetta/

Re: New server set up

[Boguslaw Faja]

Hm, unfortunately I don't use apache. Nginx is better for me. But for
other group members answers for something else may be important: why
are you using python in version 2.4? It's a bit old. Do you have
access to console (ssh) or only for some web panel (cpanel, direct)?

Best regards,

I did something wrong while registered

Hi,
I recently registered for the group and I must have done something wrong 
because I am receiving every posting twice (duplicates).  Can someone fix the 
problem or direct me to where I can fix it.

Thanks in advance

Re: New server set up

[XTCHost]

Sorry, forgot to mention

It is a CentOS based VPS runing Parallels Virtuozzo with apache and
python 2.4

All I have done is a simple install of Django to the root and run
setup.py install

There seem various ways to install it but I wish to be able to set up
multiple domains through WHM using CPanel

Thanks

Re: accessing a dictionary in template

Yes i'm trying to display a table with dynamic columns.
my intention was to pass the queryset object to template and pass the
column names so that the template can generate the table dynamically.

Re: Registration

[Casey S. Greene]

What if the user puts in a "fake" e-mail that belongs to someone else? 
Then any service notifications go to the poor person who owns the e-mail 
address, not the person who signed up for the account.  Also the user 
would get to take advantage of the benefits of the service.


With B only the initial activation e-mail would get sent there.  There 
is no benefit to the user to put in a fake e-mail address because they 
still don't have access to the service.


Hope this helps,
Casey

You can do this, where Venue.contests.items is a dictionary. 
contestname contains the keys, eventcount contains the values.



{% for contestname, eventcount in Venue.contests.items %}

When it comes to Unicode and such I am not sure about anything. But
you are probably right; I redid everything very carefully with 'utf-8'
encoding now, and that seemed to work OK.

The django docs [1] say that for the clean_ method, "Just
like the general field clean() method, above, this method should
return the cleaned data, regardless of whether it changed anything or
not."

Since you're returning nothing, self.cleaned_data['username'] will be
None when saving your user hence the "auth_user.username may not be
NULL" exception.

Are you sure that you get '?' on the file if you write it this way, or
it's just
the console/editor that you're using to see the file's contents that
cannot handle
the text's encoding?

I really think write( string_content.encode( '' )) should work fine.

custom vocabularies vs translation

[bobhaugen]

I want to provide customizable vocabularies for an open-source django
project, where each deployer can use different terms for strings that
appear in templates (e.g. field names, form field descriptions, help
text, page titles, etc.)

Would django language files work for this purpose?  Everything will be
in English (at this stage), so that would involve (if I understand
correctly) customizing the English language .po file.  (Right?)

Does that smell like a reasonable solution?  Any hidden rocks?

Has anybody done anything like this, either using language files or
some other solution?  If so, how did you do it, and how did it work in
practice?

Unicode challenged

[Joakim Hove]

Hello,

I am developing a Django application, and have some Unicode problems.
I must admit I do not really understand if my problems are with Django
or Python or ... ; but hopefully someone her can shed some light on
the problem.

Setup:

1. The application is developed for the Scandinavian countries, and
will typically handle various Scandinavian letters like æåø.

2. I am developing everything on Ubuntu Linux.

3. I am using MySQL as database, currently the character_set is set to
(the default) latin-1; but I can of course change that.


What happens:

1. A user fills out a form containing one of the problematic
characters like 'Å'.

2. Django is used to validate the form, and the form content is saved
in the MySQL database.

3. I have a view fetching the content from the database, and returning
it to a users browser with the render_to_response() function.

4. In addition to rendering the template as browser output I want to
store the rendered output in a file (as a hardcopy). This fails with
UnicodeDecodeError. The code which fails look schematically like this:


template = 
context = 
string_content = render_to_string( template , context )
fileH = open( filename , "w")
fileH.write( string_content )  <--  This fails.
fileH.close()


Now - the code which works exactly as it should, i.e. 3. above, is
nearly identical but the function render_to_output() is used instead,
and no file operations. How does the browser (firefox 3.??) magically
get this right?

I have also tried replacing the write() statement with
write( string_content.encode( '' )) where I have tried the
encodings 'latin-1' and 'utf-8'; then it does not fail hard, but
instead of the wanted 'øåæ' characters I get '?' marks.

Any tips on this greatly appreciated.

Joakim

As to whether or not it is best to do it yourself, that depends on if
another module exists that does what you want, and if you thoughts on
implementing it would provide anything different than the status quo.
I have never used this myself so I cannot comment directly on it, but
you may find http://code.google.com/p/django-messages/ of use.

Re: Django on Mac OS X

[Russell Keith-Magee]

I use PostgreSQL on my Mac as well as MySQL, and I've had many fewer
problems with PostgreSQL than I've had with MySQL.

My personal opinion: Ignore all the ports/fink stuff, and get a good
native PostgreSQL install:

http://postgresqlformac.com

The 8.4.3 installer has some known problems (easy to fix if you know
what they are, but easier to avoid if this is your first time), but
other than that, this is a pretty reliable source of installers and
native tools. Once you've got the database installed, psycopg2
installs from source fairly cleanly.

Yours,
Russ Magee %-)

Daniel,

Did you manage to have the application running on sqlite3 ... ?
I develop on Mac & have few issues... so may be you could first ensure
everything is working without postgresql connector ... ?

Simple FormWizard wizard howto/example

[PieterB]

Hi,

I'm still pretty new to django and searching some simple FormWizard
examples

What I want to do:
First step: ModelChoiceField is populated with queryset
Second step: A ChoiceField needs to be populated with
object.get(model__field__exact=resultfromstep1)'
In the last step I want to show all values for this last model.

Thx!

Re: Django on Mac OS X

[lukaszb]

I haven't read all the comments here but if you've just started
working on osx you should definitely check out http://github.com/mxcl/homebrew
- it's a package manager which works like a charm most of the time.

Installation is extremely simple (there is even one-liner available).
If your problem is related with wrong packages installation - homebrew
would most probably fix all of them, if only you can get rid of those
ports/finks at the first place.

Lukasz

The e-mail response serves to verify that the user who signed up does in
fact have control of the email address they included in their
registration details. If this step was omitted I could spam people by
signing up to a web site that sent out lots of email in their names
(and, more relevantly, their email addresses).

What is "a foreign email address"?

How to handle invalid deleted forms in formsets

[Tomi Pieviläinen]

(Using formset_factory, if that makes a difference)

If the user fills a form in formset incompletely and then marks it for
deletion, my form handling dies horribly. The deleted forms prevent
formset.cleaned_data from working as they don't validate and thus the
form doesn't have a cleaned_data attribute. If I try to iterate over
formset.deleted_forms and delete the forms from formset.forms, then
formset.cleaned_data crashes due to index out of range.

How should I be handling these invalid forms the user didn't want
anyway?

Re: Django on Mac OS X

[Xavier Ordoquy]

I doubt it's a mac issue.
I already ran in a couple of very painful issues with postgresql on Linux while 
having no issue with mysql on mac.
My feeling is that postgresql require far more attention than mysql and is more 
sensitive to small changes.

 According to the first comment, you might do something wrong with the 
 arguments types.
 Unless you give a table description (\d from psql shell) and the model I'm 
 not sure I can help you further.

But you haven't explained why converting the querysets to a list and
concatenating them, or just using itertools.chain(q1, q2), wouldn't
work. What sort of code do you have that relies on a queryset, and
doesn't work with anything else? Show it.

Re: Come on, share your django powered sites with others.//Fwd: A tornado powered site to show any project powered sites(open source)

[Stone Puzzle]

Yes, but this site can show more powered by information.

For example:
A site powered by python/django/jquery/apache/memcached,

the site will be listed at http://django.poweredsites.org and
http://python.poweredsites.org and http://jquery.poweredsites.org etc,

so it's more easy to share powered by information with other projects.

Re: Search Field on All Pages

[Wesley Childs]

Thanks for everyone's advice.

My final solution will be to use template inheritance to have the same form
across the site and to use the action="/search" to ensure I don't have to
import a search function into every single view.

Thanks again

Wes

Re: HttpResponseRedirect

Another approach that I used recently:

# urls.py
   (r'^ThankYou/(?P\d{4})/$', views.ThankYou),

# message defs in views.py
# messages for ThankYou page
ty_messages = {
'' : 'Invalid message specified.',
'0001' : 'Pending dealer record has been re-saved, awaiting
approval.',
'0002' : 'Pending dealer record has been saved, awaiting
approval.',
...
}

# function in views.py
def ThankYou(request, ty_msg_id):
c = Context({
'request' : request,
'show_admin' : request.user.is_authenticated(),
'ty_message' : ty_messages.get(ty_msg_id,
ty_messages['']),
})
t = get_template('ThankYou.html')
html = t.render(c)
return HttpResponse(html)

# usage example

return HttpResponseRedirect('/ThankYou/0089')

--Jeff

I used messages subsystem, as suggested before, now i have nice, clen url,  
and if anybody won't be redirected from respective form, will be  
redirected from "thanks page" to root



def kontakt(request):
if request.method == 'POST':
form = KontaktForm(request.POST)
if form.is_valid():
#do sth
messages.success(request, 'Msg was send, thnks.')
return HttpResponseRedirect('/dziekujemy/')
else:
form = KontaktForm()

return render_to_response('kontakt.html', {'form': form,},
context_instance=RequestContext(request))

def dziekujemy(request):
storage = messages.get_messages(request)
if storage:
return render_to_response('dziekujemy.html',
context_instance=RequestContext(request))

Re: manually add objects to a QuerySet

[chefsmart]

I already have the objects in an earlier chunk of the code. I don't
want to hit the database again to get something I already have in
another form. That is what I mean when I say that code like my_qs =
MyModel.objects.filter(pk=obj1.pk) is utterly silly. I already have
the objects from earlier db queries; I just need them in a queryset.
