Versioning of Models in Ruby on Rails

Question

I'm looking for a plugin/act to allow versioning of my models. It's kind of difficult to find a list of the available solutions. So far I gathered:

• acts_as_versioned
• simply_versioned
• vestal_versions

The last two solutions only require a single version table - this sounds nice, but I've got a bad feeling about how the ease of migrations will be affacted by this (because they serialize states as a string).

On the other hand, acts_as_versioned is a little bit dusty (last commit in January). Are there any recent experiences with any of these? Or other solutions (or forks) I might have overlooked?

Answer 1

Ive been working with a gem called "paper_trail". It seems to be the best solution online at the moment. It has auditing and version control in one.

Hope this helps!

Answer 2

I've worked with vestal_versions last week and yes, it is the most advanced alternative, at least in terms of space: you store just what you really need. It is an active project and the version 1.0 is going to be a huge update with many new features; just look at the 1.0 branch to know what I mean.

But after playing with it a bit, I've noticed a big flaw: performance. Every time you need an specific version, you have to go through all intermediate ones, reconstructing the version you need. This also means you cannot edit or delete a version directly, because it can mess with modifications, broking the chain. For do this, you need to process versions adequately, what vestal_versions currently does not do.

This way, for the problem I had, I ended up with my own versioning solution. I needed performance and the ability to delete and edit versions rapidly, so I sacrificed storage and developed something similiar to act_as_versioned.

BUT, if you don't need this and do not have to revert very frequently, I highly recommend vestal_versions. It is an advanced, solid solution and an active one, with a passionate developer behind it.

Answer 3

We used acts_as_audited in a project, with quite a good success.

You can find that at http://github.com/collectiveidea/acts_as_audited/

(last commit in november :-) )

Answer 4

A couple of months ago I tested a couple of solutions and vestal_versions was the most effective. There's also a great screencast here from Ryan Bates.
