Hello,

I'm trying to learn Django from the book "Practical Django Projects 2nd Edition"

I'm using Django 1.3.1 and Python 2.7.2 on Windows 7

Also I'm using Eclipse Indigo with pydev

The current project I'm working on is to create a Weblog called coltrane.

coltrane is an application that exists in a project called "cmswithpythonanddjango"

Inside the models.py is a class called Entry which holds the fields used to Enter a weblog entry.

When I go to localhost:8000/admin/ I get the option to add and Entry.

I can select this option fill out sample data, but when I try to save it.

I get the following error.

AttributeError at /admin/coltrane/entry/add/

'Entry' object has no attribute 'pubdate'

There is a field called pub_date in Entry

It's as if I have made a typing error somewhere and typed pubdate instead of pub_date.

Below is the models.py, views.py , url.py , and admin.py files

//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Here is my models.py

from django.db import models

def get_absolute_url(self):

return "/weblog/%s/%s/" % (self.pub_date.strftime("%Y/%b/%d").lower(), self.slug)

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Here is the views.py

from django.shortcuts import render_to_response

from cmswithpythonanddjango.coltrane.models import Entry

def entries_index(request):

return render_to_response('coltrane/entry_index.html', { 'entry_list': Entry.objects.all() })

Here is the url.py

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

from cmswithpythonanddjango.coltrane.models import Entry

# Uncomment the next two lines to enable the admin:

from django.contrib import admin

admin.autodiscover()

entry_info_dict = {

'queryset' : Entry.objects.all(),

'data_field' : 'pub_date'

}

urlpatterns = patterns('',

# Examples:

# url(r'^$', 'cms.views.home', name='home'),

# url(r'^cms/', include('cms.foo.urls')),

# Uncomment the admin/doc line below to enable admin documentation:

url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

# Uncomment the next line to enable the admin:

url(r'^admin/', include(admin.site.urls)),

(r'^tiny_mce/(?P<path>.*)$', 'django.views.static.serve',

{ 'document_root': 'C:/users/lau/documents/tinymce/jscripts/tiny_mce/' }),

(r'^search/$', 'cmswithpythonanddjango.search.views.search'),

(r'^weblog/$', 'cmswithpythonanddjango.coltrane.views.entries_index'),

(r'^weblog/(?P<year>\d{4})/(?P<month>\w{3})/(?P<day>\d{2})/(?P<slug>[-\w]+)/$', 'django.views.generic.date_based.object_detail', entry_info_dict),

(r'', include('django.contrib.flatpages.urls')),

# (r'^(?P<url>.*)$', 'flatpage'),

)

Here is the admin.py

from django.contrib import admin

from cmswithpythonanddjango.coltrane.models import Entry, Category

class CategoryAdmin(admin.ModelAdmin):

prepopulated_fields = { 'slug': ['title'] }

class EntryAdmin(admin.ModelAdmin):

prepopulated_fields = { 'slug': ['title'] }

admin.site.register(Entry, EntryAdmin)

admin.site.register(Category, CategoryAdmin)

I can't think of anywhere else the problem could be other than in one of the above files.

If somebody knows what the problem is I would be very grateful if they could tell me what it is.

Failing that, I would appreciate any suggestion of where else I could look.

Do you get a stacktrace from the error? You should get one, and it
should point out the code-path to the erroneous pubdate usage. If you
do not get one for one reason or another, search your project for the
string "pubdate" and go through all locations containing that string.

The code snippets you have below seem clean to me.

Thank you akaariai for replying to my post.

When I looked at the problem the next day I had a different problem.

I have since learnt that when you create a django project in eclipse you

should not select the option for an src folder as it confuse django. I have

therefore decided to restart from scratch.
