Version numbers and relations (Should object version increase when its relations change?) about sqlalchemy-continuum

[grakic]

I hacked a naive plugin that adds related by foreign key objects into the current versioning transaction. The code is not tested and probably contain bugs. It also probably contains assumptions that are only true in my models. There are no unit tests.

From some simple playing in the shell, it looks like it is working. I will keep working on this as time permits.

I would really like some feedback on this one by @kvesteri . Is the issue clear or should I describe it more in detail?

This kind of functionality can be emulated with TransactionMeta. I'm going to update the docs for how to use it.

The next version of Continuum has a plugin architecture where you could create a plugin for local versions. Also the new Activity plugin offers means for handling local histories.

Hello all, any news on incrementing object version when its relations change ? If no, is there any workaround documented ?

[billw2012]

It would be nice if this limitation was at least explicitly mentioned in the documentation related to relationships, the last place I expected to have to look to find a (sort of) solution to what appears to be a bug is in the plugin section! Given that both versions and relationships are expressed in the object model itself, the changes to the relationships should certainly affect the version. It makes sense to expect that given the intent of abstracting the underlying tables to an object model. And it appears to be a bug as the version of the relationships themselves is being incremented (as visible in the database tables) but there is no obvious way to see the versions of a relationship, because you are expected to access them via the object property of the parent (and/or child).

@grakic plugin works great with some changes to fit our code
