ExtendedActionsMixin

This is a Django mixin that allows ModelAdmin classes to execute actions without selecting any objects on the change list of the Django Admin.

To implement it you need to include the Mixin as usual (see https://docs.djangoproject.com/en/1.10/topics/class-based-views/mixins/) and define a class attribute called extended_actions containing a list of string with the name of the actions that you want to be exectued with empty queryset.

If in the action you want to use the same queryset that the user is seeing, you can use the get_filtered_queryset method also provided by the mixin

	import unittest
	from mock import *
	from datetime import datetime, timedelta
	import time # so we can override time.time

	mock_time = Mock()
	mock_time.return_value = time.mktime(datetime(2011, 6, 21).timetuple())

	class TestCrawlerChecksDates(unittest.TestCase):
	@patch('time.time', mock_time)

	To change a field name in django 1.7+

	1. Edit the field name in the model (but remember the old field name: you need it for step 3!)
	2. Create an empty migration
	$ python manage.py makemigrations --empty myApp
	3. Edit the empty migration (it's in the migrations folder in your app folder, and will be the most recent migration) by adding

	migrations.RenameField('MyModel', 'old_field_name', 'new_field_name'),

	to the operations list.
