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 !
