Ok let's descrive what i have done I subclassed the django admin to create a form that makes you choose if activate a delete and replace login inside your admin. Then i have added a form with a modelChoiceField to make you select another model instance when you are selecting an istance to delete. If you select another instance the current instance will be replaced.
This is a ModelAdmin base class you can use to make foreign key references to User a bit nicer in admin. In addition to showing a user's username, it also shows their full name too (if they have one and it differs from the username). **2009-08-14**: updated to handle many to many fields and easily configure whether to always show the username (if it differs from full name)
Since r7806, the `User` field is unsorted which makes it harder to find specific users in the list if there is more than a few. This snippet is an `django.contrib.admin.ModelAdmin` subclass which searches through all of the fields on a form and automatically sorts fields which have a relation with `User`. It also filters on having `active=True`. Just import the `SortedActiveUserModelAdmin` class in your `admin.py` and subclass your `ModelAdmin` classes from it instead of `admin.ModelAdmin`.
There are several nice ModelAdmin subclasses that provide useful functionality (such as django-batchadmin, django-reversion, and others), but unfortunately a ModelAdmin can really only subclass one at a time, making them mutually exclusive. This snippet aims to make mixing these classes in as easy as possible -- you can inherit your model admin from it, add a tuple of mixins, and it will dynamically change the inheritance tree to match. This isn't guaranteed to work with all ModelAdmins, but so long as the mixins play nice with django modeladmin they *should* work.
If you add a lot of custom `ModelAdmin` methods to `list_display` like I do, you know it can require a lot of repetition. Notice how adding 'checkbox' to `list_display` requires typing the method name 4 times: class ExampleAdmin(admin.ModelAdmin): list_display = ['checkbox', '__str__'] def checkbox(self, object): return '<input type="checkbox" value="%s"/>' % object.pk checkbox.short_description = mark_safe('✓') checkbox.allow_tags = True Using this decorator, the name only needs to be typed once: class ExampleAdmin(admin.ModelAdmin): list_display = ['__str__'] @add(list_display, mark_safe('✓'), 0, allow_tags=True) def checkbox(self, object): return '<input type="checkbox" value="%s"/>' % object.pk
Binds $Model to $ModelAdmin without having to specify each binding manually. The ModelAdmins **must** have the same name as the model (as well as same case) with Admin appended. Example: from django.db import models class SomeModel(models.Model): name = models.CharField(max_length=255) class AnotherModel(models.Model): name = models.CharField(max_length=255) # bind administration bind_administration('myproject.myapp.models', 'myproject.myapp.admin')
