Sometimes you just don't want to display every permission django has, you just want a short list showing the permissions for some of your apps (or even django core apps). GROUP_PERMISSIONS_MODELS must be a list of your app models. Dotted path (in lowercase) required, app name + model *class* name.
Based on [#2868](https://djangosnippets.org/snippets/2868/) Now with support for writing the absolute URL of file fields
Template context processor for delegating other context processors to individual apps. Useful if all views within an app require common context variables that aren't required by other apps.
Wanted a simple function to concatenate n dictionaries. Each dictionary passed in is deep copied to avoid any possible mutation of dictionaries being concatenated. Dictionary m's key/values will be overwritten by dictionary m+1's key/values.
Tag to correctly uppercase Greek characters with accent, copy the code in your templatetags folder in a file of your choice, load it in your templates {% load yourfile %} and use it as {% string|gruppercase %} the code works also with other languages, it won't modify anything (eg {% ukwork|gruppercase %} as it transforms only Greek characters (unless your language contains Greek characters).
Custom template filter to retrieve a content type of a given model instance. Useful for ModelForms which want to set the content_type field (i.e: GenericForeignKey). ### A usage example: {% load helpers %} {% with instance|content_type as ctype %} <input type="hidden" name="content_type" value="{{ ctype.pk }}"> {% endwith %} Original idea from [this stackoverflow answer] [1] [1]: http://stackoverflow.com/a/12807458/484127
An example of using concepts in Django with producers and consumers.
This module extends the standard `url' template tag in Django and adds support for fully qualified domain name URLs. It also can be extended with simple URL load balancing techniques if desired.

Validate form field that include email or emails separated by 'token' kwargs, by default ',' a comma. Return a list [] of email(s). Check validity of the email(s) from django EmailField regex (tested with 1.3, but normally will also work with 1.5)
Beware if using Amazon Simple Queue Service to execute Celery tasks which send email messages! Sometimes SQS messages are duplicated which results in multiple copies of the messages being sent. This is a simple decorator which uses a cache backend to prevent the task from executing twice in a specified period. For example: @task @execute_once_in(3600*24*7) def cron_first_week_follow_up(): """ Send a follow-up email to new users! """ pass For more info see <http://atodorov.org/blog/2013/12/06/duplicate-amazon-sqs-messages-cause-multiple-emails/> <http://atodorov.org/blog/2013/12/11/idempotent-django-email-sender-with-amazon-sqs-and-memcache/>
I can't find any workable solution, so I wrote it. (Checked it on Django 1.6)
Based on [#2369](https://djangosnippets.org/snippets/2369/) Save the snippet as actions.py within your django app, and then add an action on any model you want in it's ModelAdmin definition. Example usage: from actions import export_as_csv_action class YourModelAdmin(admin.ModelAdmin): list_display = (...) list_filter = [...] actions = [export_as_csv_action("CSV Export", fields=[...])] - Unicode fix (requires unidecode)
