Django: import-export && Grappelli

Question

I was using Django import-export app and now I want to add Grappelli in order to improve the Admin interface. I'm getting an error related to the templates. Any suggestion to get them work together?

Error:

Answer 1

Well, i think your problem is not in the template script but the extend. Your template tries to extend itself.

templates\\admin\\change_list.html, error at line 1 1 : {% extends "admin/change_list.html" %}

admin/change_list.html refers to the basic django template change_list. It seems that your django-import-export change_list template has the same path. Your change_list template from django-import-export should be in template/admin/ import_export /change_list.html

I use them together fine. I had to change this in admin/includes_grappelli/header.html :

-                    {% url admin:password_change as password_change_url %}
+                    {% url 'admin:password_change' as password_change_url %}

-                    {% url admin:logout as logout_url %}
+                    {% url 'admin:logout' as logout_url %}

-                {% url test-index as testindexurl %}
+                {% url 'test-index' as testindexurl %}

-                {% url django-admindocs-docroot as docsroot %}
+                {% url 'django-admindocs-docroot' as docsroot %}

And call it with ImportExportActionModelAdmin to avoid CSS problems.

from import_export.admin import ImportExportActionModelAdmin

class MyModelAdmin(ImportExportActionModelAdmin):
    """
    Admin class for MyModel model
    """
    form = MyModelAdminForm

    list_display = ()
    ordering = []

    resource_class = MyModelResource

Hope it helps...

I've just gone through the same problem and here's a more step-by-step approach.

Create a directory in your project for the import_export templates and add a html file for the change_list_import template.

myproj
├── myproj
│   ├──url.py
│   ├──settings.py
├── manage.py
├── db_personal #myapp
│   ├── admin.py
│   ├── models.py
|   ├── viewss.py
├── templates
|   ├── admin
|   |   ├── import_export
|   |   |   ├── change_list_import.html 
├── dashboard.py

Next, copy the following code in this template html file. Note that it needs to extend the grappelli changelist template, hence the reference to the location of this template:

{% extends "C:/Python27/lib/site-packages/grappelli/templates/admin/change_list.html" %}
{% load i18n %}

{% block object-tools-items %}
   <li><a href="import/" class="import_link">{% trans "Import" %}</a></li>
   {{ block.super }}
{% endblock %}

grappelli needs to be before import_export within INSTALLED_APPS.
