'RepeatedCompositeFieldContainer' object has no attribute 'extend'

[William Tu]

Hi,
I just downloaded the protocol buffer 2.4.1 and I followed the foo bar
example for python.
http://code.google.com/apis/protocolbuffers/docs/reference/python-generated.html
However, I got an error when I call extend (the rest are fine)

---------------------
foo = Foo()
bar = foo.bars.add() # Adds a Bar then modify
bar.i = 15
foo.bars.add().i = 32 # Adds and modify at the same time
new_bar = Bar()
new_bar.i = 47
foo.bars.extend([new_bar])
----------------------
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'RepeatedCompositeFieldContainer' object has no
attribute 'extend'

Am I using the wrong version of protocol buffer? My python is 2.6
Thanks!

William

This is probably a wrong version problem. Have you installed previous versions? Could you try:

import google.protobuf
print google.protobuf.__file__
