AutoComplete for ForeignKey and ManyToManyField.

Project description

# AutoComplete for ForeignKey and ManyToManyField
uses same syntax as the search for django-admin

requirements
* query.js (http://jquery.com/)
* query.autocomplete.js

## Example


use a fairly simple
*models.py*
class Type (models.Model):
title = models.CharField()

class Celebrity(models.Model):
name = models.CharField()

class Film(models.Model):
type = models.ForeignKey( Type )
director= models.ManyToManyField( Celebrity, related_name="director")
actor = models.ManyToManyField( Celebrity, related_name="actor")

in m2m field need to specify related_name

*admin.py*
from apps.autocomplete.widgets import *

class FilmAdmin(AutocompleteModelAdmin):
related_search_fields = {

'type': ('title',),
'actor': ('^name',),
'director': ('^name',),
}
admin.site.register( Film, FilmAdmin )

"related_search_fields" parameter is used to specify on what fields you want to search 'actor' and 'director' ties are the names given in "related_name" query syntax is similar to [searching in admin panel](http://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.search_fields)

I use the " 'actor': ('^name',) " operator ^ means the beginning of the field. and eventually will be formed about the substitution request form For example, if related_search_fieldsis set to ('^name',') and a user searches for john lennon, Django will do the equivalent of this SQL WHERE clause:

WHERE name ILIKE 'john%' AND name ILIKE 'lennon%'
