django - 无法根据请求用户制作 autocomplete_light 过滤器 taggit 标签

Question

如果这与这两个应用程序无关，我深表歉意。以下代码段将向我抛出“一旦获取切片就无法过滤查询”：

模型.py

class Cartao(models.Model):
    ...
    user = models.ForeignKey(settings.AUTH_USER_MODEL)
    tags = TaggableManager()

autocomplete_light_registry.py

import autocomplete_light
from taggit.models import Tag

class TagAutocomplete(autocomplete_light.AutocompleteModelBase):
    autocomplete_js_attributes={'placeholder': 'Ex: pessoal, serviços',}

    def choices_for_request(self):
        choices = super(TagAutocomplete, self).choices_for_request()
        return choices.filter(cartao__user=self.request.user)

autocomplete_light.register(Tag, TagAutocomplete)

Answer 1

好的，试试这样：

def choices_for_request(self):
    self.choices = self.choices.filter(cartao__user=self.request.user)
    return super(TagAutocomplete, self).choices_for_request()

抱歉，我的文档中有错误... arggggg ！
