TemplateSyntaxError: inlines is not a valid tag library

Question

Building my Django app, I have been using some code from django-basic-app, in particular the inlines application.

In my blog app, I load inlines in a template (here in blog/templates/admin/blog/change_form.html)

{% extends "admin/change_form.html" %}

{% block extrahead %}
  {% load adminmedia inlines %}
  {{ block.super }}

When I do that, I have an error

TemplateSyntaxError at /admin/blog/post/1/

'inlines' is not a valid tag library: ImportError raised loading inlines.templatetags.inlines: No module named models

The structure of the project is

blog/
    templates/admin/blog/
                        change_form.html
    ...
inlines/
    __init__.py
    models.py
    templatetags/
           __init__.py
           inlines.py
    ...

and with the import in inlines/templatetags/inlines.py

from django import template
from inlines.models import InlineType
from inlines.parser import inlines
import re

inlines is present in INSTALLED_APPS and I am using Django 1.4 with python 2.7

I am trying to have a standalone application (not linked to the project then) but I don't get why it is not detected by the blog app. The inlines models are detected by django, I am able to manage it using the admin interface, just the templatetags is failing.

Answer 1

Try to rename inlines.py module to inlines_tags.py for example, so a module and a package will not be same named. And dont forget to remove all old *.pyc files from templatetags folder
