flask_sqlalchemy example : different types with the same name in the schema: EmployeeConnection, EmployeeConnection.

[tomahim]

Hi,

I followed the instruction to use the flask_sqlalchemy example with a Python 2.7 version, when I run the app.py script, I've got the following error :

(py27) λ python app.py                                                                                                                      
Traceback (most recent call last):

    from schema import schema

    schema = graphene.Schema(query=Query, types=[Department, Employee, Role])

    ).format(_type.graphene_type, type)                                                                                                     
AssertionError: Found different types with the same name in the schema: EmployeeConnection, EmployeeConnection.  

What am I doing wrong ?

Thank you

I suspect that #98 will fix this.

Seems like this error only occurs, when using sqlalchemy.orm.relationship in the model class with a backref.

btw. tested with Python 3.6 and 3.7

@suxin1 - your fix doesn't work for me, i got this error:
TypeError: init_subclass_with_meta() got an unexpected keyword argument 'emp
loyees'
or this(if exactly like in your example):
raise ImportError("%s doesn't look like a module path" % dotted_path)
ImportError: Employee doesn't look like a module path

@ivanvorona So tricky. I actually did not test it. Sorry for my bad assumption. I'll post what i did in the original post.
