ViewDoesNotExist : Error

Question

I have the following code, as you can see there is a C_account() function in the view, but I'm still getting

**Exception Type: ViewDoesNotExist at /create_account/

Exception Value: Could not import EPM.views.C_account. View does not exist in module EPM.views.**

Any ideas what the problem might be?

The view (EPM/views.py) containing the C_account function definition:

from django.shortcuts import render_to_response
from django.http import HttpResponse, HttpResponseRedirect
from django.template import RequestContext
from EPM.forms import *
from EPM.models import *
from datetime import date
from django.contrib.sessions.models import Session
from django.conf.urls.defaults import *

from django.forms.formsets import formset_factory

import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'deducive.settings'

from django.core.management import setup_environ
from deducive import settings
import csv


def C_account(request):
 if request.method == 'POST':
    form = CreateAccountForm(request.POST)
    if form.is_valid():

    acc_act_date = form.cleaned_data['Account_Activation_Date']
    present_date = date.today()
    if acc_act_date <= present_date:
        stat = 'active'
    else:
        stat = 'inactive'

    acc_cat_id = Account_Categories_T.objects.get(cat_name = stat, category = 'status')


        sto =   GL_Account_T(account_number=form.cleaned_data['Account_Number'],
                account_name=form.cleaned_data['Account_Name'],
                                account_description=form.cleaned_data['Account_Description'],
                                parent_account_number=form.cleaned_data['Parent_Account_Number'],
                                account_manager=form.cleaned_data['Account_Manager'],
                                account_category_id = acc_cat_id,
                                account_activation_date=form.cleaned_data['Account_Activation_Date'],
                                )
        sto.save()

        return HttpResponseRedirect('/create_account/thanks/')

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

def thanks(request):
    return render_to_response('Thanks.html')

and the URLConf (EPM/urls.py), which has the C_account view correctly hooked up to the create_account/ URL:

from django.conf.urls import patterns, include, url

urlpatterns = patterns('EPM.views',
    (r'^create_account/$', 'C_account'),
    (r'^create_account/thanks/$', 'thanks'),)

What is that file named that you've headed "view"? Where is it located? – Kkt

its our views.py file its located inside the App named 'EPM' – Colossus

And does that app have an __init__.py file? – Kkt

Is the app in the INSTALLED_APPS entry in settings.py? – Nasion

Also make sure you don't have any circular imports, i.e. nothing imported in this file, should import this itself. In particular check EPM/models.py and EPM/forms.py – Sigh

Answer 1

I cracked my error finally. problem was in my forms.py, I wrote CharField as Charfield at one place. but I am still wondering why was it pointing to the error in my forms.py I got it by importing my views.py in shell.

Glad to hear you've solved the issue.

The slightly confusing ViewDoesNotExist exception is probably because Django encountered an ImportError when reading views.py (which has from EPM.forms import *, which would have triggered an exception due to the field typo you mentioned); the current behaviour is to swallow many exceptions (such as ImportError) and re-raise them as ViewDoesNotExist exceptions.

There's a four-year-old Django bug discussing how to make these error messages more helpful (mainly by catching fewer exceptions). In the mean-time, you can track down these kinds of problems by trying e.g.

from EPM.views import *

in a shell (./manage.py shell), which will show you the original exception.
