a field named "items" in InputObjectType occurs TypeError

[jiyeonseo]

I was trying to json.dumps with all inputs and some inputs had TypeError when they have a field named "items" like below.

class ConfigInput(graphene.InputObjectType):	    
    items = graphene.List(lambda: AnotherConfigInput)
    ...

when I try to json.dumps with this input, the error looks like

File "/project/venv/lib/python3.7/site-packages/playhouse/mysql_ext.py", line 36, in db_value
    return json.dumps(value)
  File "/Users/user/.pyenv/versions/3.7.4/lib/python3.7/json/__init__.py", line 231, in dumps
    return _default_encoder.encode(obj)
  File "/Users/user/.pyenv/versions/3.7.4/lib/python3.7/json/encoder.py", line 199, in encode
    chunks = self.iterencode(o, _one_shot=True)
  File "/Users/user/.pyenv/versions/3.7.4/lib/python3.7/json/encoder.py", line 257, in iterencode
    return _iterencode(o, 0)
TypeError: attribute of type 'list' is not callable

found that setattr in InputObjectType class overrides field's attr items which conflicts with the attribute items of List.

This is naming conflict, so I just solved it like below

class ConfigInput(graphene.InputObjectType):
    _items = graphene.List(lambda: AnotherConfigInput, name='items')
    ...

wonder if there is any good fix from graphene like this issue

please let me know if you need more info or examples :)

Hmm that isn't very good! We shouldn't be overriding in built class methods. I'm going to mark this as a bug but I don't have much time to work on it at the moment.
