无法根据请求用户使autocomplete_light过滤器taggit标签

问题描述

如果这与这两个应用无关，我们深表歉意。以下片段会让我一旦切片被取消就无法过滤查询：

models.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）
  

解决方案

好的，尝试这样：

  def cho ices_for_request（self）：
 self.choices = self.choices.filter（cartao__user = self.request.user）
返回超级（TagAutocomplete，self）.choices_for_request（）
  

我很抱歉，我的文档中有错误... arggggg！

I apologize if this has nothing to do with both apps. The following snippet will throw me a "cannot filter a query once a slice has been taken":

models.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)

解决方案

Ok, try like this:

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

I apologize, there is an error in my documentation ... arggggg !
