This is a context processor that will allow you to cycle the values of your MEDIA_URL context variable. It will cycle through the urls defined in settings.MEDIA_URLS, so that you can distribute your media url's between multiple servers.
This middleware will put the sessionid in every place that it might be needed, I mean, as a hidden input in every form, at the end of the document as a javascrit variable to allow the AJAX request use it and of course as a GET variable of the request. To make it work correctly the MIDDLEWARE_CLASSES tuple must be in this order: ` 'CookielessSessionPreMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'CookielessSessionPosMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', ` Hope it work for someone else out there.
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)
This is exacly the same snippet as #197 http://www.djangosnippets.org/snippets/197/ but returning search enigne, search engine domain and search term in: request.search_referrer_engine request.search_referrer_domain request.search_referrer_term I wanted to show ads only to people comming from search engines so I took snippet #197 and modify it to put that info in the request object.
This template tag takes the current GET query, and modifies or adds the value you specify. This is great for GET-query-driven views, where you want to provide URLs which reconfigure the view somehow. **Example Usage:** `{% get_string "sort_by" "date" %}` returns `all=your¤t=get&variables=plus&sort_by=date`
Allows to create bigint (mysql), bigserial (psql), or NUMBER(19) (oracle) fields which have auto-increment set by using the AutoField of django, therefore ensuring that the ID gets updated in the instance when calling its 'save()' method. If you would only subclass IntegerField to BigIntegerField and use that as your primary key, your model instance you create would not get the id attribute set when calling 'save()', buy instead you would have to query and load the instance from the DB again to get the ID.
Simply returns a created gravatar url based on input. Creates the url utilizing the full gravatar url inputs as defined at http://en.gravatar.com/site/implement/url.
Personally I hate using markdown for text input just so it can be converted into HTML. Markdown languages almost always don't support some thing I want to do; thus, why not just use HTML in the first place. Well because you don't want anybody posting any kind of HTML on your site. Solution, instead of making your users learn markdown, let them enter HTML and filter out bad tags. This is a filter I use to filter HTML for only certain allowed tags. The allowed tags can be configured with the **allowedhtml** list. To make your text input even more user friendly use a Javascript HTML editor like [FCK Editor](http://www.fckeditor.net/) so your users will have a nice GUI editor.
My modified version of the [MultiQuerySet by mattdw](http://www.djangosnippets.org/snippets/1103/) (see the link for further information). My purpose for this was to enable me to combine multiple different types of querysets together, which could then be iterated on as one object (i.e. like a tumblelog).

Something I end up doing all the time, making a boolean variable show up as a nice image. With this code you can do the following: `{% boolean_img user.is_active %}` And get the following output: `<img src="/media/icons/accept.png" alt="True" />` All you need to do is use the custom templatetag code, load it in your template and use the `boolean_img` tag. **Adjust templates, html and images where needed**
Some times I want to change the `owner` of an object to another user - problem is the object often has a lot of other objects pointing to them - I also want to update those fields. This is a generic snippet for doing just that! For instance: change_owner(obj, new_owner_id): return update_related_field(obj, new_owner_id, field="user")
This code provides a primary key field that is globally unique. It uses the pre_save method to auto-populate the field with a Universal Unique Id as the record is saved the first time.
