Rails routes with :name instead of :id url parameters

Question

I have a controller named \'companies\' and rather than the urls for each company being denoted with an :id I\'d like to have the url use their :name such as: url/comp

Answer 1

params

The bottom line is you're looking at the wrong solution - the params hash keys are rather irrelevant, you need to be able to use the data contained inside them more effectively.

Your routes will be constructed as:

#config/routes.rb
resources :controller #-> domain.com/controller/:id

This means if you request this route: domain.com/controller/your_resource, the params[:id] hash value will be your_resource (doesn't matter if it's called params[:name] or params[:id])

friendly_id

The reason you have several answers recommending friendly_id is because this overrides the find method of ActiveRecord, allowing you to use a slug in your query:

#app/models/model.rb
Class Model < ActiveRecord::Base
  extend FriendlyId
  friendly_id :name, use: [:slugged, :finders]
end

This allows you to do this:

#app/controllers/your_controller.rb
def show
    @model = Model.find params[:id] #-> this can be the "name" of your record, or "id"
end
