AttributeError: 'YourObject' object has no attribute 'select_related'

If you received this error, first check how you build up your django query. I had this error because I mis-structured it. 

what I did:

MyModel.objects.filter(somequery=somevalue).select_related(myrelation)

But what I should do:

MyModel.objects.select_related(myrelation).filter(somequery=somevalue)
