Question

在此功能中，我无法单独过滤类别。那么请告诉我该怎么做？这里我使用数组模型字段的类别和规格。从这个数组模型字段我无法使用查询

获取类别列

set category_name=Product.objects.values_list('categories', flat=True).distinct()

并且该过滤器应该是不同的值。那么检索此类别值的查询是什么

models.py

 class Product(models.Model):
           name = models.CharField(max_length=255)
           image = models.ImageField(upload_to = '',blank="True")    
           categories = models.ArrayModelField(
               model_container=Categories,
               model_form_class=CategoriesForm
       )
       specifications = models.ArrayModelField(
           model_container=Specifications,
           model_form_class=SpecificationsForm
       )
       description = models.TextField()
       reviews = models.ArrayModelField(
           model_container=Reviews,
           model_form_class=ReviewsForm
       )
       drizzly = models.BooleanField()
       complete = models.BooleanField()

       def __str__(self):
           return self.name
    class Categories(models.Model):
       name = models.CharField(max_length=255)

       class Meta:
           abstract = True

views.py

def index(request):
    data = Product.objects.all()
    category_name=Product.objects.values_list('categories', flat=True).distinct()      
    return render(request, 'db.html', data':data,'category_name':category_name})

如何在views.py
