Nested class not generated right

[trondhindenes]

I'm trying to express the following:

{                                               
    "module":  "ping",                          
    "extra_args":  {                            
                       "var2":  "value2",       
                       "var":  "value1"         
                   }                            
}                                               

I've done this in python like so:

@swagger.model
class AnsibleExtraArgsModel:
    resource_fields = {
        'arg_name' : fields.String,
        'arg_value' : fields.String,
        }

@swagger.model
class AnsibleCommandModel:
    resource_fields = {
        'module': fields.String,
        'extra_args': fields.List(fields.Nested(AnsibleExtraArgsModel.resource_fields)),
    }

However, the resulting swagger spec doesn't include the nested class:

How can I troubleshoot this?

I know this is an old issue, but it seems it still hasn't been resolved. The way I had it - partially - working was by adding @swagger.nested decorator, which in the above case would be:

@swagger.model
@swagger.nested(extra_args=AnsibleExtraArgsModel.__name__)
class AnsibleCommandModel:
    resource_fields = {
        'module': fields.String,
        'extra_args': fields.List(fields.Nested(AnsibleExtraArgsModel.resource_fields)),
    }

and the swagger doc was generated correctly. The problem I got - and that why I mentioned it worked partially - was that the nested decorator broke @classmethod decorator and SQLAlchemy select queries were not working.
