Error rate limiter
Prevents error flooding on high traffic production sites. Particularly useful to prevent clogging email servers etc. See [discussion](http://groups.google.com/group/django-developers/browse_thread/thread/1dabc9139dd750ca/1d86fdca23189a7d?lnk=gst&q=error#1d86fdca23189a7d) and [closed ticket](http://code.djangoproject.com/ticket/11565). Uses memcache if it can, or falls back to local, in-process memory where unavailable (down, etc). Tweak to your needs using setting ERROR_RATE_LIMIT (seconds). Requires Django 1.3+ or trunk r13981+

Remove named field from fieldsets
This snipped removes a specific fields from the fieldsets. This is very useful to leave a field 'out' in the admin, likewise: def get_fieldsets(self, request, obj=None): fieldsets = super(BlaModelAdmin, self).get_fieldsets(request, obj) if not request.user.has_perm('change_blah'): remove_from_fieldsets(fieldsets, ('blah',))

Declaring django views like web.py views
I work a little with [web.py framework](http://webpy.org/) and I like a lot the view definition. For each view you define a class and in that class you can define two method, GET and POST. If the http request is a GET request the GET method will be called and if http request is a POST request the POST method is called. Then you can define common stuff in another method that could be called inside each method, and you have a class for each view.

- class
- web.py
send a simple Campfire chat message from fabric script
look ma, no api! a python method for [fabric](fabfile.org) script to send a message to your [campfire](campfirenow.com) chat room. not really a django script but I didn't know where else to put it. I use it to send a deployment messages to campfire when we deploy new revisions. like the comment mentions, put your api key in ~/.fabricrc. the example api key is garbage so don't waste your time.

models with order (+admin editing)
Use this abstract model if you want to add "order" to a given model. Once you do, you will get automatic "up" and "down" links for each model row. One problem is that if the user sorts by another row, the up and down links are still there, but now don't make a lot of sense.

Print Exceptions to the Console

Use class name in templates
For use in templates: {% if object|classname:"entry" %} ... class="{{ object|classname }}" ... I couldn't find simpler solution for checking weather specific object belongs to specific class name, or just to output object's class name.

CatchTag - Catching the content and saving it to a variable
You can use this tag to "catch" some template snippets and save it into a context variable, then use this variable later. How to use it {% catch as var1 %}any tags and html content{% endcatch %} ... {{ var1 }}

Image inlining template tag lib
A custom templatetag for inlining image in the browser. The principe is to base64 encode the image and avoid a http request. There is a cache handling, you just have to specify a writable directory. An example of the utilisation (template part): [http://djangosnippets.org/snippets/2267/](http://djangosnippets.org/snippets/2267/) The explication on [http://raphaelbeck.wordpress.com/2010/11/14/make-inline-images-to-improve-performance-with-django-template-tags/](http://raphaelbeck.wordpress.com/2010/11/14/make-inline-images-to-improve-performance-with-django-template-tags/)
