Django error: got multiple values for keyword argument

Question

I get the following error when instantiating a Django form with a the constructor overriden:

__init__() got multiple values for keyword argument \'collection         


        

Answer 1

It's pretty simple: you pass request.POST and only afterward you put argument for collection_type. Onto what request.POST will be put? There is not place for that. Watch this:

In [8]: class A:
   ...:     def __init__(self, a, *args):
   ...:         print a, args
   ...:         
   ...:         

In [9]: A(None, a=None)

TypeError: __init__() got multiple values for keyword argument 'a'

Move request.POST somewhere else in the call, but remember, that named arguments come after the ones, that aren't.
