example

use a fairly simple

models.py

in m2m field need to specify related_name

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")

NEW: for inline

class Ceremony( PageSeo ):
	name	=models.CharField( max_length = 200 )
	guiding	=models.ManyToManyField( Celebrity, related_name = "guiding", blank = True )
	best_film=models.ForeignKey( Film, default = None, null = True, blank = True )

class Nominee( models.Model ):
	ceremony =models.ForeignKey( Ceremony )
	film	 =models.ForeignKey( Film, blank = True, null = True, on_delete = models.SET_NULL )
	celebrity=models.ForeignKey( Celebrity, blank = True, null = True, on_delete = models.SET_NULL )

admin.py

from apps.autocomplete.widgets import *

class FilmAdmin(AutocompleteModelAdmin):
	related_search_fields = { 

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

NEW: for inline

class NomineeInline( AutocompleteTabularInline ):
	model=Nominee
	extra=0
	
	""" describe the model fields for the search is only used for rendering the widget """
	related_search_fields={
		'film':			( 'name', ),
		'celebrity':	( 'name', ),
	}

class CeremonyAdmin( AutocompleteModelAdmin ):
	inlines=[
		NomineeInline,
	]

	related_search_fields={
	""" describe the model fields for the search """
		'guiding':		( 'name', ),
		'best_film':	( 'name', ),

	""" re-describes the same field as in inline is used to search for """
		'film':			( 'name', ),
		'celebrity':	( 'name', ),
	}

"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%'

NEW

You can also use the admin form and the additional fields are not described in the model which will refer to any existing model by WildModelSearchInput widget

search_fields format - ( "search_field", "result_field")

class FilmAdminForm( forms.ModelForm ):
	class Meta:
		model=Film
	discussion = forms.CharField( required=False, widget=WildModelSearchInput(app_label='forum',model_name='Topic', search_fields=('name','id')))

when saving in the discussion will be chosen topic id and you can handle it on your own
