Snippet List
Read more link
I couldn't find any code for a blog-style "Read more after the jump," so I made a custom filter. It will look for **<!--more-->** for the jump, like in Wordpress. In **settings.py** set **READ_MORE_TEXT** to what you want the text of the link to be. `READ_MORE_TEXT = 'Read more after the jump.'` When you call the filter in your template, pass it the absolute link of that entry. Of course, you have to have your **get_absolute_url** function defined in your model, but you should have that already, right? :P In this example **entry.body** is the content of the blog entry. `{% load blog_filters %}` `{{ entry.body|read_more:entry.get_absolute_url }}` If anyone has a better way to do this, it is, of course, welcome.

Templatetag startswith + message tuned
Template: `<div id="messageBox_{{ forloop.counter0 }}" style="border:1px solid #ccc;background-color:white" onclick="document.getElementById ('messageBox_{{ forloop.counter0 }}').style.display = 'none';"> {% ifstartswith message "#ok#" %} <font color="green"> {% endifstartswith %} {% ifstartswith message "#error#" %} <font color="red"> {% endifstartswith %} {{ message|cut:"#ok#"|cut:"#error#" }} </font> </div>` In a view you can now do something like that: ` request.user.message_set.create(message="#ok#Hello User, this is a ok message!")`

HTTP method_required Decorator
Edit: As James pointed out, `django.views.decorators.http` already provides stuff for this. Use that instead. Old description: Should be pretty straightforward; you give it the method you can accept, it returns 405's for other methods. EG, `@method_required("POST")` at the top of your view.

OwnerField
This is a little helper for associating an owner to a newly created object, in this case making the assumption that the current user is always the owner. It removes the necessity of adding a custom save hook to your model. get_current_user comes from this middleware trick to cache the current user: http://code.djangoproject.com/wiki/CookBookThreadlocalsAndUser

Integer list to pattern function
This function can be util for transform pattern lists like these to strings: >>> list_to_pattern([42, 43, 44, 45]) '42-45' >>> list_to_pattern([15, 49, 50, 51, 52]) '15,49-52' >>> list_to_pattern([0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]) '0-13' You can use also the pattern to list function at [http://www.djangosnippets.org/snippets/495/](http://www.djangosnippets.org/snippets/495/)

A simple rest template filter
**Attention! This snippet must be ignored**, like [zgoda](http://www.djangosnippets.org/users/zgoda/) pointed with reason: already exists this functionality in `markup` contrib. **Explanations:** This template filter allows you to render easily a reStructuredText to **HTML** or another format it supports. **Setup:** Insert the snippet into an_app/templatetags/restutils.py. **Use in template:** `{% load restutils %}` and use it as following: - `{{ entry.content|rest:"html" }}`

Partial JSON template rendering
this decorator will render template and encode it as JSON string if it find **ajax_request** variable in GET. It will not parse parent (extended) templates, only given template and nested (included). Only blocks will be rendered and encoded to JSON naming block__*BLOCKNAME*. Simple javascript can do ajax request adding *?ajax_request* or *&ajax_request* (if needed) and update given html elements if they id's are same as block__*BLOCKNAME*. you can find a full code (including javascript) at my (http://projects.barbuza.info/trac/browser/django_addons/django_ajax/trunk/ sandbox).
