Hi all, as a part of making db migrations unconditional we need to have all models easily collectible . Currently we have a head.py file containing imports to all models. Disadvantage is that all imports need to be collected manually and maintained in case new module with model is added to the tree.
Original suggested approach was to consolidate all models into one directory providing simple import of all models. This approach wasn't liked so I tried to implement alternatives. 1) os.walk neutron directory, search for "model_base.BASEV2" occurrences and import such modules. 2) Import all models in the tree excluding UT and neutron.db.migration (since it contains frozen models). I did simple benchmark of three mentioned approaches, could be found here . On a DB meeting today we agreed that least painful way will be importing all modules with pkgutil. Considering this will be used only in testing and autogenerate, memory consumption and speed are imho acceptable. We'd like to know your opinion, and especially Mark's opinion, on mentioned approaches and if we can agree on the approach chosen on today's meeting.
