Django 1.7, KeyError: u'manager' error

[Taenyon Kim]

I had a problem in using django 1.7.

Example:

class ModelA(models.Model):

    fielda = models.CharField(max_length=10)

class ModelsB(models.Model):

    modela = models.ForeignKey(ModelA)

    fieldb = models.CharField(max_length=10)

when I query like " modela_instance.modelb_set()', I will get KeyError: u'manager'.

How can I resolve this problem?

Hi Taenyon,

This list is for development on Django itself.

I see you've also asked the question on the `django-users` mailing list, which is the right mailing list for your question.

You'll want to follow up any further questions on the `django-users` thread rather than this one.

All the best,

  Tom
