PyCharm warning: Expected type 'ObjectType', got 'Type[Query]' instead

class Query(graphene.ObjectType):
    # ...

schema = Schema(query=Query)

Related to #814 which was automatically closed due to staleness.

Any ideas?

Came across this looking for the same PyCharm warning, but in a different situation. I’m not a user of this repo, so I won’t take the time to locate the code and PR the simple fix for it.

TL/DR:

Whenever you see PyCharm complain with

Expected type X, got Type[X] instead

that’s a possible type hinting misunderstanding. See this for more information.

In summary:

# Wrong
class Schema:
   def __init__(self, query: MyClass):

# Right
from typing import Type

class Schema:
   def __init__(self, query: Type[MyClass]):

Thank you for the reply! I’m sorry I still don’t understand how to do this, since I’m not defining the class Schema in my own code. All I’m doing is using graphene.Schema: So I don’t know where the type hint should go, since there’s no class Schema in my code… Would you be so kind to tell me how you accomplished this? Did you subclass graphene.Schema? Thanks in advance 😃

change the doc present in graphene/types/schema.py

replace:

query (ObjectType): Root query ObjectType. Describes entry point for fields to read data in your Schema.

with

query (Type[ObjectType]): Root query ObjectType. Describes entry point for fields to read data in your Schema.

After that problem will resolve
