Snippet List

Add delete buttons to admin changelist

This adds a checkbox for each object and three buttons to a model's change list: 1. **Delete selected:** deletes the selected objects 2. **Delete shown: ** deletes all the visible objects. For example, if you perform a search or in any way filter the list, this button deletes only objects that were filtered. 3. **Delete all: ** Deletes all instances of the model, including those not shown (if looking at a filtered list). The deletes perform no confirmation -- once you hit the buttons the models are **gone**, so maybe don't use (or add a confirmation screen) for really sensitive stuff. * uses django oldforms-admin (ie 0.96) * works fine if you include a search_fields list in the Admin class * code for the view could probably be refactored a bit :)

Foldable Admin Interface

Have you had a rather huge database, say 50-100+ tables? Why not compress the tables you don't want to see and expand the ones that you do want to see? This template should do the trick. It uses cookies to remember which tabs you have open and which ones you have closed. This should work on .91 to current. How to install - just CP code and save as index.html toss in your media folder under /path_to_media/template_folder/admin/index.html. next download mootools and toss this into /path_to_media/js_folder/mootools.js (alternatively you could be lazy and cp mootools into the script tag of this template) A quick and dirty fix but it sure saves time trying to find the tables you are looking for.

Search djangosnippets.org

I was tired browsing via tag to find snippets I saw a while ago. So I created a custom search engine with Google. To try it out go to [http://henning.cco-ev.de/django/djangosnippets.html](http://henning.cco-ev.de/django/djangosnippets.html)

make an unordered html list

This custom filter takes in a string and breaks it down by newline then makes each separate line an item in an unordered list. Note that it does not add the <ul> </ul> tags to give the user a chance to add attributes to the list. This is based of the 'linebreaks' filter built in django

Use django-admin.py instead of manage.py

A lot of people new to Django don't realize that `manage.py` is [just a wrapper](http://www.djangoproject.com/documentation/django-admin/) around the `django-admin.py` script installed with Django and isn't needed. (You may need to symlink `django-admin.py` to someplace in your system `PATH` such as `/usr/local/bin`.) The most important thing it does is to set your `PYTHONPATH` and `DJANGO_SETTINGS_MODULE` environment variables before calling `django-admin.py`. Those same settings are needed when you move your site on to a production server like Apache, so it is important to know how they work. This shell function sets those variables for you. Put it in your `.zshrc` or bash startup script. It works for both the monolithic project style and the lightweight app style of Django development [[1](http://www.pointy-stick.com/blog/2007/11/09/django-tip-developing-without-projects/)], [[2](http://www.b-list.org/weblog/2007/nov/09/projects/)]. This function isn't fancy; drop a comment if you have an improvement. Written for zsh and tested with bash 3.1.17.

Template tag for compressed CSS & JS (GAE version)

Extension of the idea from [WuzHere example from Google IO](http://code.google.com/p/wuzhere/) about creating one compressed js or css file. Original code used not very elegant if statements. I've changed it to template tags. On production server it will also use current version id. Insert code in *cssjs.py* file in *templatetags* dir in your application and use as below (more details in docs): `<script type="text/javascript" src="/media/jsmergefile.js"></script>` **This code does not compress CSS and JS on the fly, because GAE is read-only and using Datastore is too heavy.**

Template tag: split list to n sublists

Based on [this snippet](http://www.djangosnippets.org/snippets/660/), adapted to split a list into *n* number of sublists, e.g. split a list of results into three evenly-divided sublists to enable display of the results in three columns on one page with CSS. Tag: `{% list_to_columns your_list as new_list number_of_columns %}` The split_seq solution comes from a comment by Sebastian Hempel on [this post](http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/425397). More info [here](http://herself.movielady.net/2008/07/16/split-list-to-columns-django-template-tag/).

List all Form Errors

You can place this code above your form and it will list out all errors in your form if there are errors. Sometimes I like listing the errors at the top of the form because I think it looks cleaner. Make sure you add error_messages={'required': 'My detailed error here'} in your view.py for your form.
