The code will start to get messy. You wouldn't be able to simply extract out the routes into another file. You would have to still use the Rails.application.routes.draw, but then would also need to figure out how to not overwrite what you've already required. The method that I've demonstrated in this episode was fairly unobtrusive.

You could however, do something like this

config.paths["config/routes"] += Dir[Rails.root.join('config/routes/*.rb’)]

And it would probably have a similar effect, however, I don't think that it is as 'clean'.

I've been thinking about making a helper gem for bootstrap. Waiting for the official release of v4 or at least a beta ( and time to actually do it ).

I saw that during my research. However, it didn't seem to support Bootstrap 4 yet. For < 4, it would definitely be a great option!

You should be able to simply add a class attribute to the link_to methods as you normally would to get the styling.

I see, keep in mind that the UsersDatatable is its own class and nor really part of the model or controller.

You could extract out the contents of the data method into its own class which I would probably do for larger tables.

As far as the classes on the td tags, that should be possible to do with their API. I'll look into it.
