How to add new view to Ruby on Rails Spree commerce app?

Question

A very basic question that I cannot seem to solve is how to add a new view to my Ruby on Rails Spree commerce application. What I want to do is have a link next to the Home link in the _main_nav_bar.html.erb and when you click it have displayed an about page at the place where the products are displayed. So:

home about       cart
---------------------
things of the HOME page
---------------------
footer

Click on about leads to:

home about       cart
---------------------
things of the ABOUT page
---------------------
footer

In views/shared/_main_nav_bar.html.erb the link I created (based on the home link) looks as follows:

<li id="home-link" data-hook><%= link_to Spree.t(:home), spree.root_path %></li>
<li id="about-link" data-hook><%= link_to Spree.t(:about), spree.about %></li>

The AboutController I created looks as follows:

module Spree
  class AboutController < Spree::StoreController

    def index

    end
  end
end

And finally, in config/routes.rb I added the following code:

root :about => 'about#index'

When I now try to start the server it just does not work anymore without giving an error message.

Can someone please help me out on this issue? How do I add a view and create a working link that loads in the main div?

EXTRA: routes.rb

MyStore::Application.routes.draw do


  mount Spree::Core::Engine, :at => '/'

  Spree::Core::Engine.routes.prepend do
     #get 'user/spree_user/logout', :to => "spree/user_sessions#destroy"
  end


  get '/about' => 'spree/about#index'
  get '/contact' => 'spree/contact#index'


end

Thanks for your help. I did and it says: `ArgumentError missing :controller Extracted source (around line #63): root :about => 'spree/about#index'` I do have the controller in spree/about_controller.rb which I placed in the post. — user2609980, Feb 01 '14 at 12:53
Now the code in routes.rb looks like this: `root :to => 'home#index'` `root :about => 'spree/about#index'` and it gives the error `ArgumentError Invalid route name, already in use: 'root' You may have defined two routes with the same name using the :as option, or you may be overriding a route already defined by a resource with the same naming.` — user2609980, Feb 01 '14 at 13:06
Dude, you can't have multiple **root** in one application. Either do this: `get '/about' => 'spree/about#index'` for your case. — Surya, Feb 01 '14 at 13:07
Okay seems logical, when I do get it says it cannot find the controller again. Message: `Argumenterror missing :controller Extracted source (around line #63): root :to => 'home#index' get :about => 'spree/about#index'`. — user2609980, Feb 01 '14 at 13:11
I updated the routes.rb with the `get '/about' => 'spree/about#index'` and the server starts again without errors! Thanks! The link does not work though. I have `
You're new to spree, I suppose? Do: `get '/about' => 'spree/about#index', :as => :about` in routes.rb and in link(view template): `

You need to do in routes.rb:

Spree::Core::Engine.routes.prepend do
  get '/about', :to => 'about#index', :as => :about
end

or without the Spree::Core scope:

get '/about', :to => 'spree/about#index', :as => :about

Because, you have your about_controller.rb i.e. AboutController defined inside Spree module. And, hence you'll have to reference the spree namespace in your route to set it properly.

In your views:

<li id="about-link" data-hook><%= link_to Spree.t(:about), spree.about_path %></li>

or

<li id="about-link" data-hook><%= link_to Spree.t(:about), main_app.about_path %></li>

Well you helped a lot so far, but it is not completely working. I still get the error: `NameError in Spree::Home#index undefined local variable or method about_path in
<%= link_to Spree.t(:about), about_path %>

If it didn't solve your problem then why you accepted the answer? Well.. idk why `about` isn't working because, `:as => :about` should set two routing helpers:`about_path` and `about_url` for your application. And, I find it weird that you're getting error at about_path.. – Surya Feb 01 '14 at 14:05

Ha you helped me so much so far I thought I give you some credit. ;-) – user2609980 Feb 01 '14 at 14:07

See this: http://guides.rubyonrails.org/routing.html#naming-routes as you can find, for logout, you get logout_path and logout_url. So, I am clueless why it isn't working here. see the update, maybe it helps. :/ – Surya Feb 01 '14 at 14:12

it is an issue with Spree: see http://stackoverflow.com/questions/10064533/adding-routes-to-rails-spree-e-commerce#10215596. – user2609980 Feb 01 '14 at 14:14

Oh Okay. So, one work around can be by wrapping it within the spree block. See the update. – Surya Feb 01 '14 at 14:17

If I use your updated routes.rb code it does work in the sense that the server starts, and that the link is displayed when I hover. But when I click it I get the error: `uninitialized constant Spree::Spree` with a list of the routes underneath. Any ideas? – user2609980 Feb 01 '14 at 14:29

please copy and paste the exact code I wrote. you must have had: `get '/about', :to => 'spree/about#index', :as => :about` code inside the Spree::Core block. :( – Surya Feb 01 '14 at 14:30

I have the correct code. In routes.rb there is the main `MyStore:Application.routes.draw` block and in that block a `Spree::Core::Engine.routes.prepend` block. I am able to visit the site if I place it in the latter block and refresh a few times. But then I get the error when I actually click the link. – user2609980 Feb 01 '14 at 14:38

Prefixing the route with main_app worked. As in `

<%= link_to Spree.t(:about), main_app.about_path %>

`! So now the whole problem is solved! Maybe you can update your answer with this main_app prefix in it and the explanation that "Because you're calling this inside a spree template you need to prefix it with main_app., like main_app.products_starting_with_path". :-) And thanks a lot for your effort! – user2609980 Feb 01 '14 at 14:44
