Clean your Rails routes: nesting
How resources can help you to avoid custom routes?
Feel free to have a look to the Clean your Rails routes: grouping article.
In Ruby on Rails, the routes are strongly correlated to the concept of resources.
But sometimes, you need to create custom nested routes.
So, in this tutorial, we’ll see how to avoid to create these custom routes.
Example
Few month ago, we created a my-blog application. This application allows you creating and manipulating blogposts.
Let’s have a look to the config/routes.rb file
Well, that makes the job.. But it’s not RESTful!
How refactoring this code to ensure that it follows the RESTful guidelines?
The answer is: by using resources!
Here, we simply define a nested resource with only one CRUD action: create.
So, the route will be defined as following: POST /posts/:id/comments and it’ll look for a CommentsController#create action to be implemented.
⚠️ Try not to implement more than one level of nesting ! It could make your code harder to maintain by creating resource dependencies.
Voilà!
