python - FieldError at /autocomplete/ItemsAutocomplete/ -

i using autocomplete_light in django model form.

this model form

class ca_dispensaries_item(timestampedmodel):   item = models.foreignkey(items)   dispensary = models.foreignkey(ca_dispensaries)   description = models.charfield(max_length=5000, null=true) 

this form

class camenuform(autocomplete_light.modelform):    class meta:      model = ca_dispensaries_item      exclude = ('dispensary',)      autocomplete_fields = ('item',) 

registered as

autocomplete_light.register(items, search_fields=('item_name')) 

when try enter values in item, per autocomplete feature, starts searching gives field error cannot resolve keyword u'i' field. choices are: arizona_dispensaries_item, ca_dispensaries_item, colorado_dispensaries_item, created, id dont know i coming from. also, dispensaries_items of models. while created , id field names

you have forgottent comma! change

search_fields=('item_name')

to

search_fields=('item_name',)

search_fields should iterable, if has value ('item_name') (which string) 'i', 't', 'e', etc (that's why message cannot resolve keyword u'i' field)

also, there serious problems names models: see have model named items , model named ca_dispensaries_item. should not name models in plural, items should item , need use camelcase class names, ca_dispensaries_item should cadispensariesitem``.
