 Project Readme

Seriously, enough with the double render error already.

When you render or redirect, in 99% of the cases you are done. Rails though stubbornly wants you to return explicitly, and punishes you if you don't. Sinatra was done with this long ago using the halt idiom. Frankly, I don't see any use in the explicit returns except for creating more shitwork for the developer. So...

This module uses throw to bail out of any Rails controller action immediately upon calling #render, #redirect_to or #head. No more return ... and forgetting that return .... Also works wonders with fresh_when and friends.

Usage is explicit. To gift all of your controllers with early-return powers, extend your ApplicationController with the module.

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
  extend EnoughWithTheDoubleRenderAlready
  
  ...
end

All the DoubleRenderErrors will instantly disappear. Under the hood, the module installs an around_action hook and uses throw to abort your controller action in place.

Beware that some controllers (especially third-party etc.) may be surprised at your heavy-handedness, so I would limit this to the controllers you write yourself.

Contributing to enough_with_the_double_render_already

  • Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
  • Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
  • Fork the project.
  • Start a feature/bugfix branch.
  • Commit and push until you are happy with your contribution.
  • Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
  • Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
