NoMethodError in Shop#new

Im pretty new to Ruby but now i get an error when i try to at an barber to my database.

I get the following error:

NoMethodError in Shop#new

Showing /Users/Augus/Rails/Barbershop/app/views/shop/new.html.erb where line #3 raised:
 

undefined method `barbers_path' for #<#:0x105bfe360>
Extracted source (around line #3):

1: <H1>New barber</H1>
 2: 
 3: <%= form_for @barber do |f| %>
 4:  <%= f.text_field :name %> <br />
 5:  <%= f.submit %>
 6: <% end %>
 

I really dont know what im doing wrong.

My shop_controller.rb:

  def new
     @barber = Barber.new
   end
 

My view new.html.erb:

<H1>New barber</H1>
 
 <%= form_for @barber do |f| %>
     <%= f.text_field :name %> <br />
     <%= f.submit %>
 <% end %>
 
 <%= link_to 'Back', shop_path %>
 

And i do got this in my routes:

  resources :shop
