Draper VS PaperTrail

So what about the world outside Rails defaults? There are quite a few independent projects trying to help build components in the Rails view layer, among the more famous being Draper (utilizing the decorators pattern) or Cells (full-featured components in views). In the end, we decided to take a deeper look into a relatively new one – the ViewComponent framework.

If you are not a big fan of writing Rails custom helpers, you can always opt-in for a View Model pattern with the Draper gem. Or you can roll your own View Model pattern here, it shouldn't be that complicated. If you are just starting out with your web app, I suggest starting slowly by writing custom helpers and if that brings pain, turn to other solutions.

The Draper gem is the one I'm familiar with which does this well, I'm sure there are others.

Don't introduce decorators and view models. Use helpers instead. Don't extract domain models. Put the code in the ActiveRecord models and the controllers. Don't reach for interactors to model your domain logic. Don't try to avoid duplication too early.

if the source (web) application makes their own audit tables. ex: our ruby on rails application uses the paper-trail gem

We use paper_trail for this

I think you could use that in conjunction with the paper_trail gem, as /u/GreenCalligrapher571 mentioned, which is also a good suggestion. As an additional note, when changing records in production while using the paper_trail gem, I suggest wrapping your database-mutating statements executed in the rails console within a whodunnit block, so PaperTrail.request(whodunnit: 'Dorian Marié') { widget.update name: 'Wibble' } or something rather than just widget.update name: 'Wibble'. Or, if you have some sort of issue-tracking / ticketing system, you could set the whodunnit value to the ticket number or whatever, and then anyone who wants to know why the records are in the state they're in can consult that ticket, which hopefully has additional relevant context.

For a while we did this using the paper-trail gem. This was a very simple way to add a few lines of code to keep track of all of the changes made to an ActiveRecord model. But it came with one drawback. Every change to the data had to be done through ActiveRecord. There are often times when this makes an app vulnerable to a race condition. I’ll use a contrived example so as not to share any real code from our client’s app.

In most designs, this would probably not be possible unless a table tracking extension is being used in an ORM. Even with change tracking enabled through extensions like paper trail or Django simple history, it can be tricky to restore deleted entities. Object tracking would need to have been enabled before it is needed to ensure the data is still around to be restored.
