Django, query filtering from model method

Question

I have these models:

def Foo(Models.model):
    size = models.IntegerField()
    # other fields

    def is_active(self):
         if check_condition:
               


        

Answer 1

class Page(models.Model):
    category = models.ForeignKey(Category)
    title = models.CharField(max_length=128)
    url = models.URLField()
...

class Category(models.Model):
    ...
    open = models.BooleanField(default=True)

May be you can use simple filter, for this type of conditions.

Page.objects.filter(category__open=True)
