jonathan updated THRIFT-4281:
-----------------------------
Flags: Important
Priority: Critical (was: Major)
> 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
> 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
> )
