If you've worked on a Rails app for long enough, you've had to get bulk actions work in a controller and likely ended up with a huge `case` statement that intercepts a `submit` value. Did you know how can hack Rails controllers to dispatch those to actions for you? š§µš
The trick is to override a controller's `method_for_action` method and have it return the name of the batch method that's posted by the form's parameters.
Here's what the form looks like that generates the payload for the `BatchActions` concern. The `form.submit` buttons are where all the magic happens. Note how the `value` attribute maps to the controller action.
When you combine the two, you get a really clean way to handle bulk resource actions in Rails. It also makes it easier to integrate libraries like Pundit since the `before_action` works as you'd expect. I wrote more about how this works at https://terminalwire.com/artic... āļø
