Routing issue. No routes found, but I know these exist - ruby-on-rails

Question

Noob here.
Trying to figure out how to display a method in my controller into my index page. Here is what I have thus far.
Controller -
class SammichesController < ApplicationController
def index
#sammiches = Sammich.all
end
def create
#sammich = Sammich.find_by_name(params[:sammich][:name])
end
def random
#sammichy = Sammich.rand(params[:sammich][:name])
end
end
Routes-
Sammiches::Application.routes.draw do
resources :sammiches do
get "random"
end
root :to => 'sammiches#index'
Index-
<h1>All my Sammiches</h1>
<%= form_for Sammich.new do |f| %>
<%= f.label :sammich %>
<%= f.text_field :name %>
<%= f.submit 'Find Sammich', :id => 'sammich_submit' %>
<% end %>
<%= link_to "Random sandwich", sammich_random_path %>
routes-
sammich_random GET /sammiches/:sammich_id/random(.:format) sammiches#random
sammiches GET /sammiches(.:format) sammiches#index
POST /sammiches(.:format) sammiches#create
new_sammich GET /sammiches/new(.:format) sammiches#new
edit_sammich GET /sammiches/:id/edit(.:format) sammiches#edit
sammich GET /sammiches/:id(.:format) sammiches#show
PUT /sammiches/:id(.:format) sammiches#update
DELETE /sammiches/:id(.:format) sammiches#destroy
root / sammiches#index
Error-
localhost:3000 - Routing Error
No route matches {:action=>"random", :controller=>"sammiches"}
Try running rake routes for more information on available routes.
Any assistance would be much appreciated.
Thanks!

If you look at your route it has :sammic_id in there as well:
sammich_random GET /sammiches/:sammich_id/random(.:format) sammiches#random
Which means you need to pass an id to your URL helper sammich_random_path which you haven't.
Update your routes to this:
resources :sammiches do
collection do
get "random"
end
end
After adding that your route would be just /sammiches/random
