I am starting to develop in ROR. The user history that I am doing now is a Contact Page. The codes for the MVC are listed below:
app/controller/contatos_controller.rb
class ContatosController < ApplicationController
def new
@contato = Contato.new
end
def create
@contato = Contato.new(secure_params)
if @contato.valid?
flash[:notice] = "Mensagem enviada de #{@contato.name}."
redirect_to root_path
else
render :new
end
end
private
def secure_params
params.require(:contato).permit(:name, :subject, :email, :content)
end
end
app/models/Contato.rb
class Contato
include ActiveModel::Model
attr_accessor :name, :string
attr_accessor :subject, :string
attr_accessor :email, :string
attr_accessor :content, :string
validates_presence_of :name
validates_presence_of :subject
validates_presence_of :email
validates_presence_of :content
validates_format_of :email,
with: /\A[-a-z0-9_+\.]+\@([-a-z0-9]+\.)+[a-z0-9]{2,4}\z/i
validates_length_of :content, :maximum => 500
end
app/views/contatos/new.html.erb
<h3>Contato</h3>
<div class="form">
<%= simple_form_for @contato do |form| %>
<%= form.error_notification %>
<%= form.input :name, autofocus: true %>
<%= form.input :subject %>
<%= form.input :email %>
<%= form.input :content, as: :text %>
<%= form.button :submit, 'Submit', class: 'submit' %>
<% end %>
</div>
config/routes.rb
Rails.application.routes.draw do
resources :contatos, only: [:new, :create]
root 'static_pages#home'
end
When I try to access http://localhost:3000/contatos/new, the following error is displayed:
NameError in ContatosController#new
uninitialized constant ContatosController::Contato
app/controllers/contatos_controller.rb:4:in `new'
What I found about this error is that it is related to typos, but this does not seem to be my case. It's probably a silly mistake, but I could not find it. Can anybody help me?
