django-admin-wizard

django-admin-wizard is a Django app providing helpers for django admin actions with intermediate forms.

Description

Do you know "delete selected" action in Django-admin? This package provides helpers for creating such actions with intermediate forms in two lines of code. Also, you may add a link from django admin change page to a custom form view to perform some form-supplied action on single object.

Installation

pip install django-admin-wizard

Working example is in testproject.testapp.

1. Add application to installed apps in django settings:

   INSTALLED_APPS.append('admin_wizard')

2. And an action to your admin:

   from django.contrib import admin
   from admin_wizard.admin import UpdateAction
   
   from testproject.testapp import forms, models
   
   
   @admin.register(models.MyModel)
   class MyModelAdmin(admin.ModelAdmin):
       actions = [UpdateAction(form_class=forms.RenameForm)]

3. Add custom view to your admin:

   from django.contrib import admin
   from django.urls import path
   from admin_wizard.admin import UpdateDialog
   
   from testproject.testapp import forms, models
   
   
   @admin.register(models.MyModel)
   class MyModelAdmin(admin.ModelAdmin):
   
       def get_urls(self):
           urls = [
               path('<int:pk>/rename/',
                    UpdateDialog.as_view(model_admin=self,
                                         model=models.MyModel,
                                         form_class=forms.RenameForm),
                    name='rename')
           ]
           return urls + super().get_urls()

4. Add a link to custom dialog in admin change page:

   from django.contrib import admin
   from django.urls import reverse
   
   from testproject.testapp import models
   
   
   @admin.register(models.MyModel)
   class MyModelAdmin(admin.ModelAdmin):
      readonly_fields = ('update_obj_url',)
   
      def update_obj_url(self, obj):
          # FIXME: it's XSS, don't copy-paste
          url = reverse('admin:rename', kwargs=dict(pk=obj.pk))
          return f'<a href="{url}">Rename...</a>'
      update_obj_url.short_description = 'rename'

Now you have "rename" action in changelist and "rename" link in change view. Enjoy :)
