Question

我似乎无法使django-autocomplete-light与django contrib用户模型一起工作。总是得到例外＆＃39;选择应该是一个查询集＆＃39;

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（在forms.py中）：

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

尝试使用{{form}}进行渲染时，会抛出异常：选项应该是一个查询集：堆栈：

/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django 1.6在开发中运行。我创建了用户。 django-autocomplete-light可以使用autocompleteListBase工作，例如：

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

所以urls.py包含注册表，url已注册并正在加载javascript。遵循这些文档： http://django-autocomplete-light.readthedocs.org/en/latest/index.html#tutorial

任何指针？

谢谢！

嗯，明白了......文档没有提及，但需要在自动完成类中明确定义选择。

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

django-autocomplete-light with User - 选择应该是一个查询集
