Let’s Build with Ruby on Rails – Extending Devise – Custom Routing

Continuing my Let’s Build with Ruby on Rails – Extending Devise series I take a look at Devise custom routing options within a Ruby on Rails application harnessing the Devise gem.

Download the Kickoff Tailwind Template I reference in this tutorial (optional):

https://github.com/justalever/kickoff_tailwind

In this guide, you’ll learn how to use my kickoff_tailwind template (linked above) to install and create a new Ruby on Rails app. Among many other configurations, the template sets up Devise for quick use immediately. Out of the box some defaults come with devise but I add a couple of new fields (username, name) to each given user account.

Customizing routing is quite easy in the context of the devise gem. A basic install on a fresh ruby on rails app might look like the following:

Rails.application.routes.draw do
  devise_for :users # default custom method for rendering all routing
  root to: "home#index" # devise requires some sort of root option to redirect back to
end

Extending the default paths from say /users/sign_in or /users/sign_up might be something you want to customize based on your own apps logic and/or branding. Doing so it pretty straight forward. In the end I made the following changes.

Rails.application.routes.draw do

  devise_for :users,
    path: '', # optional namespace or empty string for no space
    path_names: {
      sign_in: 'login',
      sign_out: 'logout',
      password: 'secret',
      confirmation: 'verification',
      registration: 'register',
      sign_up: 'signup'
    }

  root to: 'home#index'
end

Above you can see how the defaults are overwritten with string values which essentially just update the URL pathnames accordingly. You don’t need to modify view or controller names in your app which is great but also kind of confusing as most of the time those things match. I’ve worked with Devise long enough for this issue to not affect me a great deal but it might be something worth considering for your own projects.
