PushPinImageField is a Django form field that is a sub-class of an ImageField. The field accepts an image to upload and based on certain settings, notably the size of the resulting image, the sizes and colors of 3 different borders, as well as the color of the push pin, a re-sized image is created with a colorized push pin in the top-center. A live demo of the field as well as more detailed usage instructions are available as a [blog entry](http://www.robmisio.com/blog/2/).
The django admin (as of 1.3) doesn't allow for short_description (and other ModelAdmin function attributes) to be a callable. Until that happens, this handy snippet allows you to return dynamic descriptions. Note, I haven't actually tested this yet -- but I plan to when I have the free time.
Sorl thumbs for the lazy. **Usage:** {% thumb p.image "noimage.png" %} *tags.py* goes into your templatetags directory. *includes/thumb.html* goes into your templates directory. [Fork it here.](https://gist.github.com/985439)
Usefull for TinyMCE, to allow some HTML but be vunarable by XXS attacks You need to install html5lib sudo easy_install html5lib
This code provides a mixin and decorator which, when used together, can provide advisory locking on model methods. It provides locking by using MySQL's advisory lock system. See the example at the bottom of the code. This is a convenient and easy way to guarantee your model methods have exclusive access to a model instance. The LockableObjects class requires a MySQL backend, but it could be modified to use other back-end locking systems. The lock name generation in `LockableObject.get_lock_name()` could be altered to create much more complex locking schemes. Locking per-object, per-method for example.. Lock attempts have a timeout value of 45 seconds by default. If a timeout occurs, EnvironmentError is raised. **See the bottom of the script for an example** > **Instructions:** * **1:** Place the code in locking.py somewhere in your path * **2:** In your models.py (or any script with an object you want to lock): `from locking import LockableObject, require_object_lock` * **3:** In the model you want locking for, add the `LockableObject` mixin * **4:** Decorate the method you want to be exclusively locked with `@require_object_lock`

This is auth_data_required decorator analogous to login_required where authentication data must come in POST of request. It's useful for API. I took the idea from [Tumblr API](http://www.tumblr.com/docs/en/api).
Tag for iterating through the fields of an object from a template. The tag is passed two string arguments, the name of the model to use (which is then looked up in the context dictionary), and the format string. The format string should include two string place holders. The tag will output each field name and value according to the format string supplied.
Motivation: We can't use GeometryCollections to do filters, etc in GeoDjango due to incomplete underlying libraries. But with this CollectionFrom field we can get all the benefits of working with GeometryCollections but still query based on points, lines, polys. If you're using GeometryCollectionFields and see this error: DatabaseError: Relate Operation called with a LWGEOMCOLLECTION type. This is unsupported. Then this will probably be helpful for you.
Default URL handler allows views to be loaded without defining them in the urls.py. Views will therefore be loaded based on the pattern of the browser url. For example http://host/app_name/view_name will load project_name.app_name.views.view_name. Though I would not used this in production, it can be used to speed-up development.
To convert string to lower case replace upper() for lower()
Formats a django variable using a python string formatting as specified in another template variable. Similar to |stringformat. Takes two arguments: the django template variable with the item to be formatted and the django template variable containing the format string. {% pyformat number formatstringvar %} Place this file in `appname/templatetags/pyformat.py` and you're good.
Repsonse with JSON in any case, either if it's a model, queryset or whatever
