James E. King III closed THRIFT-4281. ------------------------------------- Resolution: Incomplete Assignee: James E. King III Not enough information to go on here. Please provide the contents of a .thrift file and a file trying to use it so we can reproduce it. > Got a NameError when using class defined in ttypes.py > ----------------------------------------------------- > > Key: THRIFT-4281 > URL: https://issues.apache.org/jira/browse/THRIFT-4281 > Project: Thrift > Issue Type: Bug > Components: Python - Compiler > Affects Versions: 0.9.2 > Environment: Thrift version 0.9.2 > Reporter: jonathan > Assignee: James E. King III > Priority: Critical > > Here the problem happens. > See the error first: > from ttypes import * > File "../gen-py-ofs/ofs/ttypes.py", line 200, in <module> > class FeatureGetParams: > File "../gen-py-ofs/ofs/ttypes.py", line 210, in FeatureGetParams > (2, TType.LIST, 'featureScenes', (TType.STRUCT,(FeatureScene, > FeatureScene.thrift_spec)), None, ), # 2 > NameError: name 'FeatureScene' is not defined > Class FeatureScene is defined in line 391 of ttype.py, and is used by another > class GetParams in line of 200. Then I got this error. > I have a test. > *If I moved class FeatureScene to the front of class GetParams, the error was > gone.* > I googled character of language Python, it did happen in this situation that > we must define it at the place before we refer to it. > So I have a question, if it's true, *{color:red}why doesn't ttypes.py > generate two classes in the correct order?{color}* > It confused me for a while. Hope get your reply, thank you. > Paste details of two classes for you reference: > Defined in line 391: > class FeatureScene: > """ > Attributes: > - featureSceneType > - featureKeys > """ > thrift_spec = ( > None, # 0 > (1, TType.I32, 'featureSceneType', None, None, ), # 1 > (2, TType.LIST, 'featureKeys', (TType.STRING,None), None, ), # 2 > ) > Defined in line 200: > class GetParams: > """ > Attributes: > - orderId > - featureScenes > """ > thrift_spec = ( > None, # 0 > (1, TType.I64, 'orderId', None, None, ), # 1 > (2, TType.LIST, 'featureScenes', (TType.STRUCT,(FeatureScene, > FeatureScene.thrift_spec)), None, ), # 2 > ) -- This message was sent by Atlassian JIRA (v7.6.3#76005)
