Issue with Thrift Python Bindings

[Jonathan Kupferman <jk...@umail.ucsb.edu>]

Hi all,
I am trying to use the generated Python for a simple thrift file and seem to
be running into issues. I am able to generate and use the Ruby code without
a problem yet I seem to be doing something wrong with the python code.
Included below are the two thrift files used:

--------test.thrift----------
namespace py Sample

struct Name {
    1: string n
}

struct User {
    1: i64 id,
    2: Name user_name
}
-------- end test.thrift----------

--------test_service.thrift-----------

include "test.thrift"

namespace py Sample

service TestService {
  test.User get_user(1: i64 id),
  test.Name get_user_name(1: i64 id),
}
--------end test_service.thrift-----------

I generate the python code using "thrift --gen py test.thrift" and then
"thrift --gen py test_service.thrift" (I've also tried recursive with the
same result). I then go in the gen-py directory and type:

>>> import Sample
>>> import Sample.ttypes
>>> from Sample import *
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "Sample/TestService.py", line 205, in <module>
    class get_user_result:
  File "Sample/TestService.py", line 212, in get_user_result
    (0, TType.STRUCT, 'success', (Sample.ttypes.User,
Sample.ttypes.User.thrift_spec), None, ), # 0
AttributeError: 'module' object has no attribute 'User'

Am I doing something wrong here?

Thanks

You can't have two separate .thrift files with the same namespace,
since they will both generate ttypes files and one will clobber the
other.  If this is a feature that people really want, we could probably
make this possible.
