django-inline-actions 0.1.0

Screenshot

Installation

1. Install django-inline-actions

   pip install django-inline-actions

2. Add inline_actions to your INSTALLED_APPS.

Integration

Add the InlineActionMixin to your InlineModelAdmin and the InlineActionsModelAdminMixin to your ModelAdmin. Each action is implemented as a method on the InlineModelAdmin and has the following signature

def action_name(self, request, obj, inline_obj)

1. request - current request

2. obj - instance of the parent model

3. inline_obj - instance on which the action was triggered

and should return None to return to the current changeform or a HttpResponse. Finally, add your method name to the actions property. To add your actions dynamically, you can use the method get_actions(self, request, obj=None) instead.

This module is bundled with two actions for viewing (inline_actions.actions.ViewAction) and deleting (inline_actions.actions.DeleteAction). Just add these classes to your InlineModelAdmin and you’re done.

Example

Imagine a simple news application with the following admin.py.

from django.contrib import admin
from inline_actions.admin import InlineActionsMixin
from inline_actions.admin import InlineActionsModelAdminMixin

from .models import Article, Author


class ArticleInline(InlineActionsMixin,
                    admin.TabularInline):
    model = Article
    actions = []

    def has_add_permission(self):
        return False


@admin.register(Author)
class AuthorAdmin(InlineActionsModelAdminMixin,
                  admin.ModelAdmin):
    inlines = [ArticleInline]
    list_display = ('name',)


@admin.register(Article)
class AuthorAdmin(admin.ModelAdmin):
    list_display = ('title', 'status', 'author')

We now want to add two simple actions (view, unpublish) to each article within the AuthorAdmin. The view action redirects to the changeform of the selected instance

from django.core.urlresolvers import reverse
from django.shortcuts import redirect


class ArticleInline(InlineActionsMixin,
                    admin.TabularInline):
    # ...
    actions = ['view']
    # ...

    def view(self, request, obj, inline_obj):
        url = reverse(
            'admin:{}_{}_change'.format(
                inline_obj._meta.app_label,
                inline_obj._meta.model_name,
            ),
            args=(inline_obj.pk,)
        )
        return redirect(url)
    view.short_description = _("View")

Since unpublish depends on article.status we must use get_actions to add this action dynamically.

from django.contrib import admin, messages
from django.utils.translation import ugettext_lazy as _


class ArticleInline(InlineActionsMixin,
                    admin.TabularInline):
    # ...
    def get_actions(self, request, obj=None):
        actions = super(ArticleInline, self).get_actions(request, obj)
        if obj:
            if obj.status == Article.PUBLISHED:
                actions.append('unpublish')
        return actions

    def unpublish(self, request, obj, inline_obj):
        inline_obj.status = Article.DRAFT
        inline_obj.save()
        messages.info(request, _("Article unpublished"))
    unpublish.short_description = _("Unpublish")

Example Application

You can see django-inline-actions in action using the bundled test application test_proj

git clone https://github.com/escaped/django-inline-actions.git
cd django-inline-actions/test_proj
./manage.py migrate
./manage.py createsuperuser
./manage.py runserver

Open http://localhost:8000/admin/ in your browser and create an author and some articles.
