django-searchable-select - a better and faster multiple selection widget with suggestions for Django

Project description

django-searchable-select

A better and faster multiple selection widget with suggestions for Django

What is this?

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

You can use this as custom widget for ManyToManyField.

Features

  • 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.

Installation

  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', limit=10)
            }
    
    
    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.
    • limit (optional) specifies the maximum count of entries to retrieve. Defaults to 10.

Example app

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