带有参数的Rails中更好的路线

Question

I've been working on a movie application in Rails. I have a controller/view for the actor. When passing params to the actors controller i want the URL to be pretty. Now it looks like this: http://localhost:3000/actors/show?actor=Hayley+Atwell and i want it to look like /actors/show/Hayley+Atwell or /actors/Hayley+Atwell .

How do i do this? My link in the movies view is:

<%= link_to a.name, {:controller => 'actors', :action => 'show', :actor => a.name}, :class => "label label-default" %>

My routes.rb is now like this:

get 'actors/show'

Answer 1

I recommend you use friendly_id gem. It perfectly satisfies your needs!

Answer 2

您可以在./config/route.rb文件中使用以下命令：

get '/actors/:actor', to: 'actors#show'

Answer 3

I'll give a series of refactoring advice as follow:

• Try to make use of the actor's id instead of the name
• Change the route to: get '/actors/show/:id', to: 'actors#show'

Then, you can now change the link in your view to something like:

<%= link_to a.name, {:controller => 'actors', :action => 'show', :id => a.id}, :class => "label label-default" %>

Note: the : part in the :id of your route means that this could be interchanged to anything, and whatever comes in that place will be interpreted as the id . So, in /actors/show/7 , the id of the actor is 7, you can now find the actor with this id in your controller action, and do anything you want with it.

Answer 4

If I'm right than you try to create RESTful routes anyway.

So I would recommend you to use the Rails' resources method in your routes:

Rails.application.routes.draw do
  resources :actors   # If you want only the :show action than add:
                      # , only: [:show]
end

This automatically creates the proper routes for you.

To get the names into the URL you should use the friendly_id gem . It has a great community and is very well tested.
