how to access m2m through table fields

[harry389]

here are the model i have:
class A(Model):
foo = IntegerField()

class C(Model):
b = ForeignKeyField(B)
a = ForeignKeyField(A)
bar = IntegerField()

class B(Model):
foos = ManyToManyField('A', through='C')

if i wanted to display objects of class C (ie i want to display 'bar'
field of C objects), how should i change my handlers?

So the API read you're discussing is on C directly, and you want a list of C objects with only their 'bar' field displayed? I think simply including fields=('bar',) should do the trick. Am I missing something?

the way i am doing this is by adding a property to class B like:

class B(Model):

   foos = ManyToManyField('A', through='C')

 

   def get_foos(self):

      return C.objects.filter(b=self)

and in the handler for B put the 'get_foos' in the fields

class BHandler(BaseHandler):

   fields = ('get_foos')
