A better and faster multiple selection widget with suggestions for Django

This plugin provides a replacement for standard multi-choice select on Django admin pages.

You can use this as custom widget for ManyToManyField.

• Filtering is performed on server side and thus significantly improves performance.
• Uses Twitter Typeahead to provide suggestion completion.
• Works great with ManyToMany fields that can be chosen from thousands of thousands of choices, e. g. User - City relations.

1. Install django-searchable-select.

   $ pip install django-searchable-select

2. Add 'searchableselect' to your settings.

   # settings.py
   
   INSTALLED_APPS = (
       # ...
       'searchableselect',
       # ...
   )

3. Add URL pattern required for the suggesting engine to your root urls.py.

   # urls.py
   
   urlpatterns = patterns(
       '',
       # ...
       url('^searchableselect/', include('searchableselect.urls')),
       # ...
   )

4. Use the widget in your model admin class:

   from django import models, forms
   from searchableselect.widgets import SearchableSelect
   from models import Traveler
   
   class TravelerForm(forms.ModelForm):
       class Meta:
           model = Traveler
           exclude = ()
           widgets = {
               'cities_visited': SearchableSelect(model='cities.City', search_field='name', many=True)
           }
   
   
   class TravelerAdmin(admin.ModelAdmin):
       form = TravelerForm
       
   admin.site.register(Traveler, TravelerAdmin)

   Remember to always initialize SearchableSelect with three keyword arguments: model, search_field and many.

   • model is the string in form APP_NAME.MODEL_NAME representing your model in the project, e. g. 'cities.City'
   • search_field is the field within model that will be used to perform filtering, e. g. 'name'
   • many must be True for ManyToManyField and False for ForeignKey.

Just run the project from example directory, head to http://127.0.0.1:8000, login as admin/admin and try adding Cats!

• Python 2.7.x: Django 1.7, 1.8, 1.9, 1.10
• Python 3.x: Django 1.8, 1.9, 1.10

• Not tested with empty fields.

I'm looking forward to bug reports and any kind of contribution.
