带有用户选择的django-autocomplete-light应该是一个查询集

Question

我似乎不能让django-autocomplete-light与django contrib用户模型一起工作。总是获取异常‘选项应该是一个查询集’

这是我的自动完成类(在autocomplete_ligh_registry.py中定义)：

import autocomplete_light
from django.contrib.auth.models import User
class UserAutocomplete(autocomplete_light.AutocompleteModelBase):
    search_fields = ['first_name']
    model = User
autocomplete_light.register(UserAutocomplete)

我的表单(forms.py格式)：

class TransactionForm(forms.Form):
    mymodel = forms.ModelChoiceField(  required=True, 
                                       queryset=User.objects.all() , 
                                   widget=autocomplete_light.ChoiceWidget('UserAutocomplete'))

当尝试使用{{form}}呈现时，它抛出一个异常:选项应该是一个queryset: stack：

/home/prj/docs/projectos/.../src/autocomplete-light/autocomplete_light/widgets.py in render
        choices = autocomplete.choices_for_values() ...
▶ Local vars
/home/prj/docs/projectos/.../src/autocomplete-light/autocomplete_light/autocomplete/model.py in choices_for_values
        assert self.choices is not None, 'choices should be a queryset' 

这是正在开发中的django 1.6。我已经创建了用户。django-autocomplete-light在autocompleteListBase上工作正常，例如：

class OsAutocomplete(autocomplete_light.AutocompleteListBase):
    choices = ['Linux', 'BSD', 'Minix']
autocomplete_light.register(OsAutocomplete)

所以urls.py包括注册表，urls被注册，javascript被加载。遵循这些文档：http://django-autocomplete-light.readthedocs.org/en/latest/index.html#tutorial

有什么建议吗？

谢谢!

嗯，明白了.文档没有提到，但它需要在autocomplete类上显式定义选项。

class UserAutocomplete(autocomplete_light.AutocompleteModelBase):
    search_fields = ['email']
    choices = User.objects.all()
    model = User
autocomplete_light.register(UserAutocomplete)
