Link to show action

Quick question: how do I link to a show action by id in my header menu? I have created a show page called about using the friendly_id gem. Pages was created with the scaffold command.

How do I then link to that specific show page in the main header menu?

show page:

currently have: <%= link_to "About", pages_path, :action => "show", :id => 'about' %> but that doesn't work?

page model:

extend FriendlyId
  friendly_id :title, use: :slugged


def show
    @page = Page.friendly.find(params[:id])


resources :pages
get '/about', to: 'pages#show', :via => [:get, :post], :defaults => {:id => 'about'}
Rails.application.routes.draw do
  get '/pets/new', to: 'pets#new'
  get '/pets/:id', to: 'pets#show'
  post '/pets', to: 'pets#create'

I haven't used friendly_id before, although I have a pretty good guess how it works...

In this code:

<%= link_to "About", pages_path, :action => "show", :id => 'about' %>

The second argument should be a string with the path that the final link will point to. The pages_path method should return "/pages", but I think you actually want "/about". Since you haven't named the get "/about" route, I think you'll need to use the literal string "/about".

Side note regarding this route:

get '/about', to: 'pages#show', :via => [:get, :post], :defaults => {:id => 'about'}

You should probably take the :via option out. I don't think you want POST requests going to the show action, and :via => [:get] is redundant with calling the get method anyway.

Ah thank you! I was over complicating it.
