NullBooleanField fails as radio buttons
I'm struggling to get a NullBooleanField to work as radio buttons. By
default, a NullBooleanField (NBF) shows up as a select widget with
options: "Unknown", "Yes", "No". I assumed I could add this to
"radio_fields" and have it turn those options into radio buttons with
the same labels. But no dice: I get an error that radio_fields only
works with FKs and when choices is set (I think this is an oversight,
as BooleanFields and NullBooleanFields have implicit choices).
Anyway, I wrote my own choices, add 0, 1, and '' blank options to the
field, which works fine, except that Django insists on giving me an
additional blank option "None" when I have blank=True set (which is
required if I want the field to allow saving as None/blank).
Ok, so I consider those two things bugs -- 1) boolean-type fields
should accommodate the RadioSelect widget without extra work and, 2)
given explicit "choices", the field should not add its own
"blank" ("None") option (especially when a blank option is provided in
those choices).
My real question is: how can I change the label of the "None" option?
As it stands, the only way I can get NBF to work as radio buttons is
with the options: "None", "No", "Yes", which is completely ambiguous.
I would like to change "None" to "Hidden" (even "Unknown" -- which is
what's used in the select widget -- would be fine).
Am I overlooking an easy way to change this label? If the answer is to
subclass the RadioSelect widget (presumably to get it to work the way
it already should), could someone help start me with the code, or
point me to a good resource for subclassing widgets?
Thanks!
Josh

Re: Best Django host
Thanks for replying. When you mention like that, yeah it looks way simpler than what is shown. Can you use a domain name like www.mysite.com? It does not need to be a subdomain, right? Also after you get the welcome screen, how do you install your django application you downloaded from the net? Thanks.

How to write subdomain from django apps

But all you need to do to setup django is to create a django application in applications and then in sites assign a domain name for it or use the default username.webfactional.com and that's it. You point your browser to the domain name and get the Django welcome screen. It takes about 1minutes or less to do all that. Even installing satchmo took about 10minutes only,including installing all the dependencies. I have tried many hosting companies and webfaction is the best so far.

Re: Installing django

@sdc, yeah I plan to try webfaction. The only thing is I just quickly
checked out their demo video to setup django and itès 21 mins. I am
blown away to see how complicated just setting this up, and I am an
experienced windows programmer. Just expected a lot less steps.
Have you checked out www.djangohosting.ch? They claim their django is
one click solution. I wonder how that one compares both for features
and the ease of installations.
@Sam, thanks for the detailed reply. I will try those out, just worry
that there will be more steps or undocumented stuff to write.
Thanks again.

At the bash command line.
Dreamhost runs Debian GNU/Linux, which offers a bash shell as standard. In
order to access a Dreamhost bash shell account from a Windows PC, you first
need to make sure your Dreamhost user account has shell access (you can set
this up in the Dreamhost Panel - look under "Users"). Then you need an SSH
("Secure SHell") client for your Windows PC, to let you access the bash
shell on the Dreamhost server (much as you need an FTP client in order to
FTP files to a remote server). The standard SSH client for windows is called
PuTTY and can be downloaded from
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
Use PuTTY to log into Dreamhost using your Dreamhost user account details,
and you should find yourself at the bash command line, within your user's
home directory. You can then run the commands above.
> 2. Also where is the .base_profile? Am I supposed to locate it

Do you mean .bash_profile? If so, it should be present in your home
directory (see above). Use the command "ls -la" to list the files there
(leave out the quotes). If it's there, fine. If not, you may need to create
it yourself.
Thanks in advance.
OK :)

I see you asked another question about the best django host, and got a lot of replies to that one. Not so many here. If dreamhost doesn't support django and you don't have unix skills, try webfaction. I'm not sure you understood this before: you will not have to manually install django on webfaction. You will select the django setup you want from a dropdown menu. And it will no doubt be a lot easier for others to help you out, both here and on the webfaction forums. Just friendly advice, of course. If anyone has experience with (or represents) any host that has an even easier setup than webfaction, hopefully they will come forward :). sdc --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Integrity error handling
hi group
I have a situation here. I need to make sure that a field is unique
in the database. In my model i have the following:
url= models.CharField (max_length=254, blank=False,
db_index=True,unique=True)
When i go to save, it throws the IntegrityError just like it should.
How can i trap that error and send it back to the form gracefully with
the data still intact and throw a form validation error message? I'm
assuming that it has to be done through clean data but i'm not sure
how to implement...
here is my view:
def Addme(request):
if request.method=='POST':
form=FrmWebPage(request.POST)

[br...@vpac.org: selecting foreign keys]
Hello,
I tried to send this several months ago via the Gmane NNTP server, but I
suspect it didn't get through. At least I can't find it.
The same problems seems to exist with the current subversion code.
My apologies if this did get through and was discussed, if so could somebody
please provide a link to the discussion?
Thanks.

Subject: selecting foreign keys
To: undisclosed-recipients: ;
Newsgroups: gmane.comp.python.django.user
Hello,
A frequent problem people seem to have with Django[1] is the default
interface for selecting foreign keys is slow and clumsy to use if there
are lots of selections. To the best of my knowledge there is no solution
included with Django.
So I have created my own field type that is derived from the
django.forms.CharField form type. The Clean method will look up the
value in the db with the matching name, and return the result. Simple.
Efficient. No need to repeatedly query the database/objects for the same
data, if the same foreign key appears multiple times on the same form. I
like it.
The problem comes to using this with the admin interface. I created a
class derived from django.db.models.ForeignKey that overrides the
formfield method to use my field type. Unfortunately this does not work[2].
The issue is that the admin interface automatically wraps the widget
with the RelatedFieldWidgetWrapper, which does not work because this
wrapper assumes the widget is compatible with the Select field. However,
the widget used by CharField is not compatible, as it (obviously)
doesn't have a concept of choices.
So I get the error: 'TextInput' object has no attribute 'choices'
From: /home/brian/tree/django/django/contrib/admin/widgets.py in
___init__, line 203
Is there anyway I can tell it not to wrap the widget in this manner?
The wrapping seems to take place at
~/tree/django/django/contrib/admin/options.py, line 140, inside the
formfield_for_dbfield function - it looks like it checks the field type,
but makes no attempt to check the widget type is compatible.

Re: FormWizard and ImageField - "this field is required" error
UPDATE:
I found a workaround, but it's not pretty. Has anyone done this in a
more elegant manner?
1) when defining the initial data to pass into the FormWizard (I do
this in a view wrapped around the FormWizard):
if len(request.FILES):
initial.update({'request_files':request.FILES})
2) Override the FormWizard subclass's __init__ method and tack the
files onto the object so they can be accessed later:
def __init__(self, form_list, initial=None):
files = initial.get('request_files', None)
super(ProfileWizard, self).__init__(form_list, initial)
self.files = files
3) Override get_form to pass the files as a parameter to the form:
def get_form(self, step, data=None):
return self.form_list[step](data,
prefix=self.prefix_for_step(step),
initial=self.initial.get(step, None), files=self.files)

FormWizard and ImageField - "this field is required" error
In the last step of my FormWizard, I have an ImageField. I've made sure that the uploaded image is appearing in request.FILES, but I'm still getting a "this field is required" error upon submission. I assume that this problem is related to this ticket: http://code.djangoproject.com/ticket/7439 Without patching the core, is there a way to work around this to initialize the Form with request.FILES?

Custom urlconfs in django.contrib.auth tests failing when reverse is used in templates
I have the contrib.auth app installed, and in order for its tests to pass, I have to define certain registration templates. When defining those templates, if I use the url tag / reverse to point to a view outside the auths app, the auth tests fail. This occurs because the auth tests use a custom urlconf and have no knowledge of views elsewhere in the project -- on one hand, this makes sense since the auth app shouldn't be expected to know about the URLs in the project it's included in. On the other hand, the auth app invites us to write its own template -- and it seems reasonable that the template used for a login page might also have a link to another page in the app. For example, my registration templates extend a base template that has a nav bar pointing to views in other apps. Any ideas on how to work around this? -- Andrew --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Right, there are 2 solutions to that (that I can think of). 1 is to
write a template context processor. The other is to write a custom
inclusion template tag. I personally favor the 2nd one because it gives
you
a little bit more control.

Not sure how to do it?
{% for category in categories %}
{{

{% for section in %}
But how to get all sections from one category?
And the second question
If I am passing a variable to the base template (I want to use the code
to generate menu from categories), how to handle it in separate (extended
templates)? E.g. do I have to query categories in each my view and pass it
as value to all templates I use?
Thanks in advance

For a 404 you should still be able to just raise the exception, for other
response you could create your own Exception like ResponseIsReady and just
raise it and have __init__ return as soon as it's done.

Re: Callable objects instead of functions in views.py
Yeah, I did a quick check in the interpreter and this is indeed very cool.
There is another thing though that worries me (but just a little).
Often, when I write views, it's nice to be able just to return 404 or
302 at any moment and not proceed with a current function. For 404 it
can be always done by just raise Http404. Inside views functions 302
can also be easily done by return HttpResponseRedirect('location').
But when it is done inside a method in a class, it can't be done so
easily. For example:
class SomeResponse(HttpResponse):
def __init__(self, *args, **kwargs):
self.some_method(*args, **kwargs)
def some_method(self, *args, **kwargs):
# need redirect here - this won't work
return HttpResponseRedirect(..
Is there any elegant solution, which would allow to break, just when
it's needed?

Disabling middleware on a per view basis
Hello, I've been vigorously searching for a way to disable middleware on a per view basis, something like: @disable_middleware def my_view(request): ... I'm wondering if something like this might be possible right now or if anyone else has had the need for this? -- I'm asking this because I'm developing an application which serves some dynamic views that only runs a few database queries, but which never return anything but an empty HttpResponse, which makes things such as LocaleMiddleware and SessionMiddleware add unneeded overhead for each hit. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

oh... That was naive ... anyway may help someone else.
Just pass all the required dojo attributes like dojoType,trim ..etc as

forms.widgets.TextInput(attrs_dict=your_dict,...)
Also add dojo.require(dijit.form.TextBox)

Right, there are 2 solutions to that (that I can think of). 1 is to write a
template context processor. The other is to write a custom inclusion
template tag. I personally favor the 2nd one because it gives you a little
bit more control.

Your class should inherit from "forms.ModelChoiceField", not just
ModelChocieField.

Alex -
I really appreciate your help. I made the changes you suggested and
it's shown here:
class MyModelChoiceField (ModelChoiceField):
def label_from_instance(self,obj):
return "My Object #%i" % obj.id
class FrmWebPage (forms.Form):
active = forms.ChoiceField(required=True, choices=active_choices,
widget=forms.RadioSelect(attrs={'class':'choiceselect'}))
page_category_id = MyModelChoiceField
(queryset=PageCategory.objects, empty_label='Choose',required=True,
widget=forms.Select(attrs={'class':'dropbox'}))
[snip]
page_weight = MyModelChoiceField(required=True,
choices=weight_choices, widget=forms.Select(attrs=
{'class':'dropbox'}))
and the result is:
name 'ModelChoiceField' is not defined

Displaying objects in template
Hi!
I have a model with a Sections and Categories related this way:
class Category(models.Model):
categoty = models.CharField(max_length=200)
name = models.CharField(max_length = 200, help_text=u"Имя категории")
def __unicode__(self):
return u"Категория %s" %self.name
class Section(models.Model):
section = models.CharField(max_length=200, unique=True)
name = models.CharField(max_length=200, blank = True)
category = models.ForeignKey(Category, blank=True)
def __unicode__(self):
return u"%s" %(self.section)
I passed a categories to the template. Is there a way I can display all
sections related to each category in template?
Not sure how to do it?
{% for category in categories %}
{{
category.name}}
{% for section in %}
But how to get all sections from one category?
And the second question
If I am passing a variable to the base template (I want to use the code to
generate menu from categories), how to handle it in separate (extended
templates)? E.g. do I have to query categories in each my view and pass it
as value to all templates I use?
Thanks in advance

If I cut-and-paste that view, that form (fixing up the oddly broken line)
and your models from your earlier note into a test project and test out that
view, I get a page with a form. When I actually submit a file using that
form, I get redirected to '/thanks/', which gives me a "Page not found"
since I didn't set up any mapping for thanks. So, somehow you are not
actually running the code you have posted, or using the template you think
you are. At this point you need to do the standard debugging things --
start putting prints in to test the value of variables, etc. What you have
posted here does work.

Re: how can I reset the form object variable (errors)?
Hi Karen,
In one of my HTML page I have included 2 forms, where both the forms
have required=True fields and have submit buttons respectively.
The problem is when a user submits one form (by clicking one of submit
button form the page) and if at all it has some errors (as validated
in clean method of forms)
I want to populate errors only from the submitted form.
I am rendering the page in the following way in my views.py
def login(request, redirect_field_name=REDIRECT_FIELD_NAME):
if request.method == "POST":
form1 = loginForm(request.POST)
form2 = SearchForm(request.POST)
form1_hidden = request.POST.get('hiddenForm1')
form2_hidden = request.POST.get('hiddenForm2')
if form1.is_valid() and form1_hidden == 'True':
return render_to_response("homepage.html")
if form2.is_valid() and form2_hidden == 'True':
return render_to_response("searchresults.html")
else:
form1 = loginForm()
form2 = SearchForm()
return render_to_response("login.html", {
"form1": form1,
"form2": form2,
})
Now in a case where form1 has errors, I want to render the both the
forms with the errors of form1 only.
Request you to let me know a solution for the above problem.
Thanks for your patience.
Regards,
Lokesh

You don't access the class at forms.MyModeChoiceField, since it doesn't live
in that namespace. You access it with just MyModelChocieField, since it's
defined in the same file. As a note, you're going to want to have the
MyModelChoiceField class before your form (in the file), otherwise the Field
won't be defined when you go to use it.

Yes, there is URL for 'add_media_action'. As I said before all works
as expected till I restart dev. server.

I've checked it several times and found nothing wrong. Again, problems
occur just after I restart dev. server, before that moment I don't get
any errors. That's why I am so frustrated with this problem

It's very simple (from myapp/urls.py)
url(r'^add/$', login_required(views.add_media),
name = 'add_media_action'),
And my project urls.py looks like this:
urlpatterns = patterns('',
url(r'^$', 'views.index', name="index"),
(r'^data/', include('myapp.urls')),
(r'^accounts/', include('registration.urls')),
(r'^admin/(.*)', admin.site.root),
url(r'^ajax/autocomplete/$', 'views.ajax_autocomplete_action',
name='ajax_autocomplete_action'),
url(r'^about/$', 'django.views.generic.simple.direct_to_template',
{'template': 'misc/about.html'}, name="about"),
)

An addendum to others' replies - since I have several django sites still
around that were made with different releases of django from the past two
years, I like to put this in my settings.py:
{{{
from django import VERSION as DJANGO_VERSION
assert (1,1) == DJANGO_VERSION[:2], DJANGO_VERSION
}}}
(If, for example, this particular django site is expecting version 1.1.)

FileBrowser: Models for media
My application models Training courses. Those courses may have
training material in a variety of formats.
I came across FileBrowser and it seems real nice.
Are any of you using a FileBrowseField in your models?
I get the feeling that what I'm doing below is wrong... creating a
model that holds nothing but a single field just so that I can have a
ManyToMany relationship on it.
Also, why is it that FileBrowseField is not a subclass of FileFIeld or
FilePathField ?
class Course(models.Model):
name = models.CharField(max_length=100)
materials = models.ManyToManyField('Material')
class Material(models.Model):
media = FileBrowseField(max_length=200, blank=True, null=True)

Using Django with app-engine-patch to provide authentication for an application deployed on GAE
Hi, I have an application who's start page is hello.html(dynamic page where the contents change based on which user has logged in). Now I want to protect this page using django's app-engine patch so that only authenticated users can access their respective pages. I followed the example in http://code.google.com/appengine/articles/app-engine-patch.html which was a good start but now I wanted to know as to how to call a new html form from within the urls.py so that my hello.html comes up. I know that I need to add a line in urls.py "(r'^sign/$', 'helloworld.test.hello')" where there is a py file named test with a function named hello. Now how do I check if the user is auth and redirect him to hello.html???

The problem is that when language is changed labels for form's fields does not change. All the localization files are provided and properly configured. Is that somehow related to cache of page? Tried to use never_cache decorator, didn't help. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: can't get admin to work on google apps.
I am doing this for a job. I am not experienced with python nore google apps engine or django. I was hired in to make a website with html, css and that was really it. I asked about his server in the start but he said he will give me that info when I am done with the site. so when I got done he told me that they use google apps engine. I ask is that the server? I never knew google gave such services. the more I found out and dug deeper I notice it's python and their is alot to this. So I am new at this. I did asked on google app engine groups and also in the chatrooms on IRC. I am not really getting much info. I mostly get refered to documents that dosen't really help much in my situation. So far here is the django admin: dev.mobileconsultinginc.com/admin thats our admin area which is djangos admin area. It works but I just need to create the superuser. the previous programmer was able to do this. I don't understand how but he was able to do this. I also tried manually add a superuser. using manage.py or the django- admin.py createsuperuser. but had no luck. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Callable objects instead of functions in views.py
> Take a look at this: http://code.djangoproject.com/ticket/6735#comment:37 > snippet which actually does let you store state on the object. The suggested solution is very cool, but I wonder, how to change status code of such responses. status_code is a class attribute, so if while serving a request I decide I need to change it's status, I will have to change this value. But wait - if at some point I decide to for example turn the response into redirect, I can just call: self.status_code = 302 and I won't actually change the class attribute, but only instance attribute, right? So I can just subclass HttpResponse, add all stuff (like having function forbid or redirect) and it should work? -- Filip Gruszczyński --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

how can I reset the form object variable (errors)?
Hi,
Is it possible to clear the variable 'errors' of a form object? If so,
could some one please help me in clearing the errors variable.
I have tried by below scenarios but, of no use.
form1.errors = {}
form1.errors = ''
Here is the code and output details:
class SearchForm(forms.Form):
looking_for = forms.CharField(label="looking_for", required=True,
max_length=30)
ageFrom = forms.IntegerField(label="ageFrom", required=False,
max_length=30)
My form1 object holds SearchForm class.
def searchView(request, redirect_field_name=REDIRECT_FIELD_NAME):
redirect_to = request.REQUEST.get(redirect_field_name, '')
if request.method == "POST":
form1 = SearchForm(request.POST)
print 'form1 error -', form1.errors
for field in form1.errors:
print 'field is ', field
form1.errors = {} --> here I would like to clear the error
messages set by django
else:
form1 = SearchForm(request.POST)
return render_to_response("search.html", {"form1":form1})
output for the above loop:
form2 error - looking_forThis field is required.
field is - looking_for

Lokesh

Style question (model naming conventions)
Hi folks,
Let's say I have an app called "Attributes" that holds flags for user
account modifiers (e.g. "TurnOffAds"). So I might have a model inside
this app to contain all the available attributes:
class Attribute(models.Model):
name = models.CharField(max_length=50)
description = models.CharField(max_length=320)
Naturally I want these attributes actually applied to specific user
accounts within this app too, in such a way that I can reference
user.attribute_set().[...] through the reverse-relational-lookup-
thingy:
class AttributesThatTheUserActuallyHas(models.Model):
user = models.ForeignKey(User)
attribute = models.ForeignKey(Attribute)
My question is if there is an accepted naming convention for these
models; for the actual Attribute data ("Attributes" with a big "A", if
you will) and the flags that apply them to a given user ("attributes"
with a little "a").
The closest thing I've found is that essentially my "Attribute" is a
lookup table not unlike an enumeration and something like
"AttributeChoices"/"Attribute" would be appropriate, but semantically
I could also read that the other way round (i.e. is "AttributeChoices"
the list of available attributes, or those attributes which a user has
elected to receive?)
Sorry for any confusion, as I'm getting tripped up in this myself. In
a nutshell, if you have Model1 for concrete objects and Model2 that
links an arbitrary set of those objects to a foreign key, how do you
name the models?
Thanks all.
Scott

You aren't actually using that Field though, you need to use it in place of
ModelChoiceField where you want that behavior.

Re: Callable objects instead of functions in views.py
> One thing to keep in mind is that the object is shared across all requests

What exactly do you mean? Because I just got very worried.
I have a class like this:
class CreateAddressService(RequestService):
def prepare(self, request, *args, **kwargs):
self.subject = Subject.get_or_404(request.session['user_id'],
int(kwargs['subject']))
def servePost(self, request, *args, **kwargs):
self.form = AddressForm(request.POST)
if self.form.is_valid():
self.form.save(self.subject, request.session['user_id'])
return HttpResponseRedirect('/edit_address/' + \
unicode(self.subject.id))
def serveGet(self, request, *args, **kwargs):
self.form = AddressForm()
def serveBoth(self, request, *args, **kwargs):
dictionary = {'form': self.form}
return render_to_response('create_address.html', dictionary)
Does it mean, that this object can be shared across multiple requests
from multiple users?
Can I then use constructors and create an object, that will serve a
request? Would this prevent sharing the object?

Konstantin,
To elaborate on Karen's suggestion, one way to see which URLs are
among the candidates for resolving the reverse match is to
deliberately hit a bad URL like the following:
http://localhost:8000/something_that_does_not_match_urls
If you have appropriate debug settings, you should then get back a
list of all the patterns that django knows about in your browser. If
you don't see the URL for add_media_action, then you probably have
some issue with the environment, as Karen suggests.
If you do see the URL for add_media_action, then you probably want to
focus on other theories, such as the wrong number of arguments or
something similar.
Obviously, more information would help people help you figure this
out. At the very least you should provide the line of code from
urls.py that establishes the mapping for add_media_action.

Chunked transfer of a file fetched through xml-rpc
Hello everyone, here is the situation: I have a Django web server A that communicates with another local server B through xml-rpc. A storage C (NAS, but it doesn't really matter) is mounted on B. I would like to make a file located on C available for download from A. I would like to avoid copying the file on A, since it can be pretty big (hundreds of Megs sometimes) and the resources of A are limited. The solution I am thinking about (as a beginner) would be: - implementing my own FileWrapper for the remote file, so it can become iterable => every xml rpc request from A to B would get a block of data of the file on C (but it seems very wrong, a lot of overhead) - returning somehow a HttpResponse having its transfer encoding mode set to "chunked" => every time a block of data is fetched from B, it is directly sent in a chunk My question is: Is it feasible? I have read some stuff here about this, but I am a bit confused now by everything I read. It seems that the HttpResponse class iterates through all the content before sending the whole response. Is it right? Is there a way to create a chunked response? So;ething related to mod_wsgi? I am sorry if this message is not clear. It is not clear in my head neither... Any suggestion, advice, idea or question is very welcome. Thank you very much.

Re: Fwd: Best Django host
I've set up a couple Django sites on Dreamhost, as well as one on Webfaction. Webfaction is great. Dreamhost requires lots of tweaking, but you can definitely run a Django site just fine there too. I've had no issues with uptime. If you need help setting it up on Dreamhost, check out Jeff Croft's helpful guide: http://jeffcroft.com/blog/2006/may/11/django-dreamhost/.

There is no cl.formset there, that's just where Django get's the error text
from in that parciular case, you should put whatever text *you* want there
for the error message.

Re: Error notification in admin site. Should be easy!!!
Sorry, but I got lost somewhere in formsets. I'm using actions from
change_list.html, so I suppose I should use cl.formset.errors:
{% if cl.formset.errors %}
{% blocktrans count cl.formset.errors|length as counter %}
Please correct the error below.{% plural %}Please correct the errors
below.{% endblocktrans %}
{% for error in
cl.formset.non_field_errors %}{{ error }}{% endfor %}
{% endif %}
But I don't know how to access such formset from a function in my_app/
admin.py function.
Here's my class:
class SomemodelAdmin(admin.ModelAdmin):
actions = ['myfunction']
def myfunction(self, request, queryset):
for obj in queryset:
if :
self.message_user(request, "OK message")
else:
< here I want to access cl.formset.errors to display
my error messages >
Thank you

ModelChoiceField help
Hi Group. Please look at this snippet from my forms. It uses two
ModelChoiceFields as shown below. Each database table currently has 2
records.
On the webpage, when the form is being called, the options are like
this:
Template object
Template object
and
PageCategory object
PageCategory object
The values of the options are correct, but how do i get the correct
visible text in the drop box
from django import forms
from web_pages.models import PageCategory
from template_manager.models import Template
class FrmWebPage (forms.Form):
page_category_id = forms.ModelChoiceField
(queryset=PageCategory.objects, empty_label='Choose',required=True,
widget=forms.Select(attrs={'class':'dropbox'}))
template_id=forms.ModelChoiceField
(queryset=Template.objects,required=True,
empty_label='Choose',widget=forms.Select(attrs={'class':'dropbox'}))
def clean_page_category_id(self):
data=self.cleaned_data['page_category_id']
return data

Double-check or post your model definition for Shot. Sounds like it has something (verbose_name or verbose_name_plural) under class Meta that is set incorrectly.

+1 for WebFaction. The control panel look+feel may looks weird, but the simplicity is just great and you get everything you need. The structure in your home directory is also sensible.
