Increase maximum number of changelist items for "Show all" link to appear

By default, a "Show all" link will appear in the changelist pager only if fewer than 200 records are in the result. Since it is rare that there will be more than one page of records yet fewer than 200, the "Show all" link almost never shows up. Pasting this code somewhere in your app will allow you to increase the 200-record maximum. "Show all" is very handy when used in combination with batch actions and filters, and this change will enable it for most situations. Note that this allows a changelist with up to 10,000 results, which results in a lot of HTML that can tax slower browsers and older machines. For me, it has been worth the tradeoff, since my users have fast enough computers and need to be able to make batch changes efficiently.

language switcher in admin

you have a multilingual site and need to change languages in admin. Previously this was easy in the site itself and more difficult in admin. Now it is dead easy. Set up your languages in settings.py. Make a directory called 'admin' in your templates directory, copy ~/django/contrib/admin/templates/base.html to that directory. Add the following code (below breadcrumbs is a good place) this will give you a switcher for all installed languages. You would need to refresh the browser on changing the language.

MPTTModelAdmin

This builds on a couple of other people's hacks to effectively manage django-mptt models via the admin. One problem you find is if you use the actions drop-down menu to ‘delete selected’ items from your mptt model… the bulk actions bypass the model’s delete method so your left/right values for the tree aren’t updated. What you need is a way to automatically rebuild the tree after a bulk action. This code provides that facility. Full details on my blog: [http://anentropic.wordpress.com/2009/10/26/](http://anentropic.wordpress.com/2009/10/26/making-admin-bulk-delete-action-work-with-django-mptt/)

admin filters as select boxes

This templatetag let's you output a form with select boxes instead of the ul's for filters. Uses some hacks to get the param names out of query strings. This would be a lot easier if filterspecs defined params instead of query strings (if filter tag would handle the encoding)

Technical 500 by group membership

Based loosely on [Eric's middleware](http://ericholscher.com/blog/2009/sep/5/debugging-django-production-revisited/), this middleware will show the technical 500 page (which you'd get if DEBUG == True) to any user who is (1) superuser and (2) a member of the settings.TECHNICAL_500_GROUP_NAME group. (If no setting exists, 'Technical Errors' is the presumed group name. I agreed with the comments that caching should be unnecessary given the (presumptive) edge case of exception + superuser. Assuming you don't have tons of superusers, this code is a good bit simpler.

More information about users and groups in user admin

Based on [this snippet](http://www.djangosnippets.org/snippets/876/). More clean, with links to the related admin forms. Nice example on customization of contributed django admin apps. It adds the following to the user list interface: fields for is_superuser and is_staff, last login time; by default, short names of groups user is in (mousehover to see full names) It adds the following to the to group list interface: list of users in your groups. To enable, just put it somewhere and import it from your main urls.py: import utils/admin_auth.py

Custom management command to list recent admin actions

On a busy site it can be nice to have a summary of admin activity. Running this command (I call it "adminlog") generates output like this: 2009-07-10 18:06:19: pbx changed flat page: "/yay/ -- Let's All Say Yay" By default it shows the last five actions; pass it a numerical arg to show more or fewer. Run this as a cron job and you can follow a site's admin-side activity without even logging in!

Confirm alert if the user navigates away without saving changes

A confirm alert is displayed if the user has made any changes to the form, and attempts to navigate away from the page without saving (click the back button, hit reload, click the breadcrumbs, logout, etc). Much like GMail's "Your message has not been sent. Discard your message?" prompt. **Uses the JavaScript helpers built into Django**, without relying on 3rd party libs like jQuery. (There might be simpler options if you're already using [jQuery](http://code.google.com/p/protect-data/) or [prototype](http://stackoverflow.com/questions/925111/activating-onbeforeunload-only-when-field-values-have-changed/1013033#1013033)). To use this, simply create a [custom admin template](http://docs.djangoproject.com/en/dev/ref/contrib/admin/#overriding-admin-templates). For example at: *templates/admin/YOUR_APP_NAME/change_form.html* {% extends "admin/change_form.html" %} {% block after_related_objects %} {{ block.super}} <script type="text/javascript"> ... script goes here ... </script> {% endblock %}

Clear FileField/ImageField files in the Admin

The widget for FileField and ImageField has a problem: it doesn't supports clear its value and it doesn't delete the old file when you replace it for a new one. This is a solution for this. It is just for Admin, but you can make changes to be compatible with common forms. The jQuery code will put an **<input type="checkbox">** tag next to every **<input type="file">** and user can check it to clear the field value. When a user just replace the current file for a new one, the old file will be deleted.

Redirect with change list with filters intact with admin actions

When using the django admin as a means of moderating reviews on a site, the obvious choice was to use admin actions and do everything from a single screen. The I stumbled across was that after the actions were peformed, the app redirected to the change list without any filters. This meant that filtering on un-moderated reviews was lost as soon as a change was made. It turns out that the solution is pretty simple, you just put a redirect to request.get_full_path() at the end of the admin action. I think this should be the default behaviour, but the fix is simple nonetheless.
