Question

I am getting an error when I try to add a 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 #<#<Class:0x105e7b818>: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 don’t know what I am 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 %>

I also get this in my routes:

  resources :shop

By default Rails tries to figure out the path for sending forms based on the object you pass in. In your case Rails tries to build path for sending the form based on your @barber object. As your routes.rb shows, you haven’t written resources :barbers and your form fails to find proper path. You have to specify your path directly. Like this way:

<%= form_for @barber, url: shop_path do |f| %>
