import graphene
from graphene import relay
from graphene_sqlalchemy import SQLAlchemyObjectType, SQLAlchemyConnectionField


class Employee(SQLAlchemyObjectType):
    class Meta:
        model = EmployeeModel
        interfaces = (relay.Node, )


class Company(SQLAlchemyObjectType):
    class Meta:
        model = CompanyModel
        interfaces = (relay.Node, )
    
    employees = SQLAlchemyConnectionField(Employee, with_name=graphene.String())
    
    def resolve_employees(self, args, context, info):
        with_name = args.get('with_name')
        Employee.get_query().filter(EmployeeModel.name.like('{}%'.format(with_name))

resolve func should be like that python v2.7
def resolve_employees(self, args, context, info):
name = args.get('name')
return Employee.get_query(EmployeeModel).filter(EmployeeModel.name == name)

I hope that users use the example on https://github.com/jamesaxl/graphene-sqlalchemy/tree/master/examples/flask_sqlalchemy
