[Grok-dev] megrok.rdb setup error

[Christian Schmidt]

Today I ran into the same problem. The suggested pinning was not working 
an so i tried to figure out the problem.

collection is part of sqlalchemy. In versions >= 0.7 'in_link' has 
disapeared. This breaks megrok.rdb 0.12.

/megrok/rdb/components.py line 62:

     @collection.on_link


I pinned sqlalchemy to version 0.6.9

buildout.cfg or versions.cfg:

[versions]
SQLAlchemy=0.6.9

ran bin/buildout and anything was fine.

Finally I hope that there is somebody who is able to make megrok.rdb 
compatible with newer versions of sqlalchemy.

hope that this a solution for you.

Chris
