Hey guys,
I made a gem for tracking changes on specific fields in ActiveRecord
models.
Its very easy to get started using, and automatically creates models
and
associations to history objects which contain the changes made.
If you have a table like:
users: (id, email, created_at)
And you'd like to track all of the changes the email has been through
over
time, in your model you'd just write:
class User < ActiveRecord::Base
track_history
end
and create a table in a migration like:
user_histories: (id, user_id, email_before, email_after, created_at)
Automatically when you start up your server, user instances will have
#histories (an array of UserHistory objects) and UserHistory will have
some
convenience methods which you can read more about in the README.
You can also add annotations like:
class User < ActiveRecord::Base
track_history do
annotate(:day_of_week) { Time.zone.now.wday }
end
end
And the value of the annotation will be saved whenever the object is
updated.
There's are a bunch of other options to check out and configure,
such as the ability to track creates and deletes cleanly.
Check it out!
