An example of how to modify the admin user creation form to assign an unusable password to externally authenticated users when they are created. This code is more intimate with the django.contrib.auth classes than I'd like, but it should be fairly straightforward to maintain should the relevant django.contrib.auth classes change.
This patch adds a new admin Filter, for Filtering nullable fields. It adds 3 possible choices: 'All' (no filter), 'Null' (it applies field__isnull=True filter), and 'With Value' (it filters null values). This patch is interesting when you have a Integer or String fields and you want to filter wether a value is set or not. In other case, it would show too many filtering options. Remember this is a patch and you must modify a django file in `django/contrib/admin/filterspecs.py`
This uses the Really Simple Color Picker in jQuery: http://www.web2media.net/laktek/2008/10/27/really-simple-color-picker-in-jquery/ Get source from there or GitHub: http://github.com/laktek/really-simple-color-picker/tree/master
Use this code in *change_form.html* in your projects admin templates to add a character counter beside the input field(s) in admin to let users know how many characters they have remaining for a particular input field. The total number of characters allowed is determined by the max_length in your model for the models.CharField you're using this with. This code is designed to add the counter after the input field, but could easily be customized to fit the style of any admin. If the number of characters remaining is 10 or less the background color changes to yellow to visually warn the user. **Usage Examples:** In this example only the input field with id=id_pull_quote will receive the counter: $(document).ready(function() { $("#id_pull_quote").counter(); }); You could also apply the counter to all input fields on a page: $(document).ready(function() { $("form input[@maxlength]").counter(); }); **Note:** *You have to download jQuery to your project and place the appropriate call in order for this to work. The best place to do this is in the extrahead block. I left my call in as an example but your path and file name will probably vary.* Credit for base jQuery code goes to Brad Landis at [bradlis7.com](http://www.bradlis7.com).
A simple view used to manage the page cache stored in the database (here Postgresql in the django_cache table, you also have to set correctly CACHE_TABLE_OID, by the OID of the cache table (you can get it in PgAdmin)
`python manage.py inspectdb` allows you to generate the models from a legacy database. The generated model classes are not arranged by dependencies. When the number of tables is big, it becomes really painful to rearrange by hand. This small script should rearrange the models for you. It doesn't solve every problem with generated models, but it makes our the process easier
This is a view that can be used to add a print button (link) in the admin change form for an individual record. Pretty simple to use. A nice enhancement to it is to be able to pull the model field name tie with the field value, something like making {{ object.as_dl }} available to the template. PS: The code is a modification from the django.views.generic.list_detail.object_detail
If you want to add an fckeditor for every vLargeTextField (the input class used by models.TextField) you can use this javascript. you can load that in all admin pages overriding templates/admin/base_site.html with this: {% extends "admin/base.html" %} {% load i18n %} {% block title %}{{ title }} | {% trans "Administrative Area" %}{% endblock %} {% block branding %} <h1 id="site-name">{% trans "Administrative Area" %}</h1> {% endblock %} {% block nav-global %}{% endblock %} {% block extrahead %}{{ block.super }} <script src="{{media_url}}js/jquery.js" type="text/javascript"></script> <script src="{{media_url}}fckeditor/fckeditor.js" type="text/javascript"></script> <script src="{{media_url}}fckeditor/custom/vTextField.js" type="text/javascript"></script> {% endblock %}
This code sets the default sites for a sites ManyToMany property to `Site.objects.all()`, which makes sure you don't have to bother setting it for each item on a site. This could easily be changed to `Site.objects.get_current()` to use the current site as default.
This patch allows to open a popup to edit the selected object of either the left or right select input of a filter_horizontal or filter_vertical field, when pressing the "Insert" key. Being a noob with general client-side issue, it's served as a patch that suits my needs. Maybe it's possible to do it cleaner by overloading the javascript methods, or get rid of the jquery dependency in order to integrate it into django trunk ... Any contribution is welcome!

Generic Relations with django.contrib.contenttypes.generic.GenericForeignKey work well for models but the admin interface just shows the object id as an integer with no easy way to lookup the id of a new object. This jquery javascript adds a "Lookup <ContentType Name>" link next to the object id field in the admin interface. This is done by reusing the showRelatedObjectLookupPopup() function provided with django which is used when the field is included in raw_id_fields (a little magnifying glass linked to popup object selector shows up). This essentially works the same way but changes which model's objects are shown and selected in the popup based on the ContentType selected for object_type
This is a fairly small bit template that, if placed in your_project_dir/templates/admin/prepopulated_fields_js.html will override the template that is normally pulled by the preopulated fields templatetag in the admin. The result is that you can successfully specify a ForeignKey or other field involving choices as a source for prepopulate_from in your admin.py. It works just as well when there are multiple fields of both the text and choice variety.
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
From my talk this morning at PyCon UK 2008: a very simple multiple user blog model with an admin interface configured to only allow people to edit or delete entries that they have created themselves, unless they are a super user.
This snippet is based on [#748](http://www.djangosnippets.org/snippets/748/). Adds filtering by first char (alphabetic style) of values in the admin filter sidebar. The example below results in this filter: By name that starts with All A B G M X urls.py example (only for register the filter): import <your project>.admin.filterspecs models.py example: from django.db import models class Person(models.Model): name = models.CharField(max_length=40) name.alphabetic_filter = True admin.py example: class Admin: list_filter = ['name']
