Question

我正在使用django-autocomplete-light和django_filters。我看了django-filter with django autocomplete-light，但我的自动完成功能无效。

Models.py：

class ProfessionalDevelopment(models.Model):
   Name = models.CharField("Professional Development", max_length=20,default = "None")
   ProfessionalExperience = models.ManyToManyField(Person, through='PersonToProfessionalDevelopment')

class PersonToProfessionalDevelopment(models.Model):
   PersonID = models.ForeignKey(Person,  on_delete=models.CASCADE)
   ProfID = models.ForeignKey(ProfessionalDevelopment,  on_delete=models.CASCADE)
   Desc = models.CharField("Professional Development Description", max_length=30, default="None")

Views.py：

class ProfessionalDevelopmentAutocomplete(autocomplete.Select2QuerySetView):
 def get_queryset(self):
    qs = ProfessionalDevelopment.objects.all()
    if self.q:
        qs = qs.filter(name__istartswith=self.q)
    return qs

urls.py

urlpatterns = [url(r'^search/ProfessionalDevelopment-autocomplete/$', ProfessionalDevelopmentAutocomplete.as_view(),
    name='ProfessionalDevelopment-autocomplete']

Filters.py：

ProfessionalDevelopment = django_filters.CharFilter(name='professionaldevelopment__Name', lookup_expr='icontains',
                                                    widget=autocomplete.ModelSelect2(url='RSR:ProfessionalDevelopment-autocomplete'))

我收到错误说＆＃39; list＆＃39;对象没有属性＆＃39; queryset＆＃39;。然后我将代码更改为autocomplete.Select2而不是autocomplete.ModelSelect2（根据https://github.com/yourlabs/django-autocomplete-light/issues/763）。虽然没有错误，但我无法输入文本输入框。有人能帮助我吗？感谢

你想根据它的名字过滤模型ProfessionalDevelopment。您需要在以下步骤中进行修改： 1，在ProfessionalDevelopment模型上完成str或unicode，否则过滤器上显示的选项将为id。

class ProfessionalDevelopment(models.Model):
   Name = models.CharField("Professional Development", 
   max_length=20,default = "None")
   ProfessionalExperience = models.ManyToManyField(Person, 
   through='PersonToProfessionalDevelopment')

   def __unicode__(self):
       return self.name

2，更改ProfessionalDevelopment的过滤字段：

ProfessionalDevelopment = django_filters.ModelChoiceField(
    queryset=ProfessionalDevelopment.objects.all(), 
    widget=autocomplete.ModelSelect2(url="yourcompleteurl")
)

这些步骤可以解决您的问题。

并且不要忘记在模板中添加{{form.media}}

Django_filters与django-autocomplete-light
