如何在Rails中没有控制器和动作的情况下将根路径设置为“ /”？

Question

In my routes.rb I want to set the root_path to '/' without specifying any controller or action. Is that possible?

I tried root to: '/' but it's complaining, that no controller or action is specified.

Updated Info:

I'm using the comfortable-mexican-sofa CMS, and my root_path should go to the cms root path.

At the moment I'm just using redirect_to '/' in my controllers and this is working, but I thought it would be nicer to use root_path .

Answer 1

Try

root :to => "cms/content#show"

From the docs: https://github.com/comfy/comfortable-mexican-sofa/wiki/Pages

The first page you create is the homepage, and therefore you cannot specify a slug. By default, you should be able to access the homepage without specifying your root route. However, if you or a gem you are using need access to the root_path helper, specify root :to => "cms/content#show" in your routes.

Answer 2

Further to the accepted answer, the routes of Rails is all about creating the paths for your application

According to the ActionDispatch::Routing middleware documentation:

The routing module provides URL rewriting in native Ruby. It's a way to redirect incoming requests to controllers and actions. This replaces mod_rewrite rules. Best of all, Rails' Routing works with any web server. Routes are defined in config/routes.rb

This means the job of routes.rb is to take the inbound request ( / , /posts , etc) & redirect to ruby-centric code. Ruby doesn't know what / is -- it has to have a controller / action combo

That's why you'd need something like:

#config/routes.rb
root to: "controller#action"
