一对一关系和 django-autocomplete-light

Question

I have some problems with the django-autocomplete-light which I cannot resolve on my own.

models.py

from django.contrib.auth.models import User
class UserProfile(models.Model):    
   user = models.OneToOneField(User, related_name="user_profile")
   ...

autocomplete_light_registry.py

class UserProfileAutocomplete(autocomplete_light.AutocompleteModelBase):
    model = UserProfile
    search_fields = ['username']
    attrs = {
        'data-autocomplete-minimum-characters': 1,
    }

autocomplete_light.register(UserProfileAutocomplete)

I tried this but it raises an error: FieldError, Cannot resolve keyword u'username' into field.

I've already tried "user" but it raises: TypeError, Related Field got invalid lookup: icontains

What should I do?

Thanks a lot.

Answer 1

you need User model's username . so you need user__username

class UserProfileAutocomplete(autocomplete_light.AutocompleteModelBase):
    model = UserProfile
    search_fields = ['user__username'] # <-- user__username instead username
    attrs = {
       'data-autocomplete-minimum-characters': 1,
    }

    autocomplete_light.register(UserProfileAutocomplete)
