NoMethodError in Contacts#edit
Hi all, I am new to Ruby as well as Rails
I am working my way through a treehouse course and I have hit a bit of an obstacle.
This is what my routes file looks like
I am working my way through a treehouse course and I have hit a bit of an obstacle.
This is what my routes file looks like
Rails.application.routes.draw do # For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html get '/contacts/:id/edit', to: 'contacts#edit' get '/contacts', to: 'contacts#index', as: 'home' get '/contacts/new', ato: 'contacts#new', as: 'new' get '/contacts/:id', to: 'contacts#show', as: 'shows' post '/contacts', to: 'contacts#create' end
the method in the controller is as follows
def edit
@contact = Contact.find(params[:id])
endand this is what the edit.html.erb file looks like
<%= form_for(@contact) do |c| %>
<div>
<%= c.label 'First Name' %>
<%= c.text_field :fname %>
</div>
<div>
<%= c.label 'Last Name' %>
<%= c.text_field :lname %>
</div>
<div>
<%= c.label :number %>
<%= c.text_field :number %>
</div>
<div>
<%= c.submit %>
</div>
<% end %>as is this will result in the following when I I try to load the edit page (example: http://localhost:3000/contacts/1/edit)
NoMethodError in Contacts#editShowing
/Users/donovanneethling/Ruby/addressbook/app/views/contacts/edit.html.erbwhere line #1raised:undefined method `contact_path' for #<#<Class:0x007fca54438cf0>:0x007fca57e82a78> Did you mean? contacts_path
However when I amend the edit route as follows
get '/contacts/:id/edit', to: 'contacts#edit', as: 'contact'
the page loads correctly.
Would someone be able to explain this to me, I am guessing it has something to do with form_for...

Is there any specific reason you adding the routes manually instead of using `resources :contacts` (this will make sure you get all the restful urls you need)? That should definitely fix your routing problems.
If you keep to the conventions, Rails is easier to handle and doesn't give you headaches like this.
