Tightens up response content by removed superflous line breaks and whitespace. By Doug Van Horn ---- CHANGES ---- v1.1 - 31st May 2011 Cal Leeming [Simplicity Media Ltd] Modified regex to strip leading/trailing white space from every line, not just those with blank \n. ---- TODO ---- * Ensure whitespace isn't stripped from within <pre> or <code> or <textarea> tags.
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/).
Class that takes a normal none derived class and converts it into a view. The methods return simple datastructures which makes it easier to test.
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)
If you did tried to use `reverse` function to set `success_url` in class based generic views and you have got an exception, this helper function may help. Put this snipped in some file, for example utils.py and import this function.
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`
Provides a mixin view class that requires logged-in user.
A simple model ColorField that allows picking from a predefined list (currently picked up from settings.py The widget displays as a row of coloured SPAN's with the hex code inside. Simply click to choose a color. (requires jQuery in the page assigned to it's normal $ shortcut. Easy to change this is you don't use jQuery in this way)

Assuming you have defined STATIC_ROOT correctly in settings.py, and have installed staticfiles_urlpatterns() in urls.py (as demoed in the code, taken from Django's staticfiles docs), the code from static_root_finder.py can be used to simply serve static files in development from STATIC_ROOT directly, avoiding complicated setups in case we just want to have a bunch of static files in one directory.
Add this to your apache config: `<Directory /path/to/media> WSGIAccessScript /path/to/access.wsgi </Directory>` Save the snippet as access.wsgi. Set up the paths, and do some authorization checking.
Overriding settings ------------------- For testing purposes it's often useful to change a setting temporarily and revert to the original value after running the testing code. The following code doubles as a context manager and decorator. It's used like this: from django.test import TestCase from whatever import override_settings class LoginTestCase(TestCase): @override_settings(LOGIN_URL='/other/login/') def test_login(self): response = self.client.get('/sekrit/') self.assertRedirects(response, '/other/login/?next=/sekrit/') The decorator can also be applied to test case classes: from django.test import TestCase from whatever import override_settings class LoginTestCase(TestCase): def test_login(self): response = self.client.get('/sekrit/') self.assertRedirects(response, '/other/login/?next=/sekrit/') LoginTestCase = override_settings(LOGIN_URL='/other/login/')(LoginTestCase) On Python 2.6 and higher you can also use the well known decorator syntax to decorate the class: from django.test import TestCase from whatever import override_settings @override_settings(LOGIN_URL='/other/login/') class LoginTestCase(TestCase): def test_login(self): response = self.client.get('/sekrit/') self.assertRedirects(response, '/other/login/?next=/sekrit/') Alternatively it can be used as a context manager: from django.test import TestCase from whatever import override_settings class LoginTestCase(TestCase): def test_login(self): with override_settings(LOGIN_URL='/other/login/'): response = self.client.get('/sekrit/') self.assertRedirects(response, '/other/login/?next=/sekrit/')
This view acts as an extension to the object_detail generic view in django.views.generic.object_list. The standard generic view can only filter the queryset by object_id or slug; this view allows you to filter by any parameter you like, as well as multiple parameters. The usage is the same as the standard object_detail view except that you must also give the parameter 'filters', which should be an array of what you would like to filter the url values as, and instead of 'slug' or 'object_id' as the regex parameter in the URL, use 'value1', 'value2', etc. Example: If you have a list of companies, each with multiple branches, you may want a branch details page. A URL for this may look as follows: http://www.mysite.com/company/company-slug/branch-slug/. To implement this simply use the urlpattern example give,
