Inserting data to a model from a custom controller Rails

I created a scaffold for a model called "Charge", but I want to insert data to the model from a custom controller I created "Checkout".

I have the following code:

#in the routes.rb
get "checkout/pay", to: 'checkout#index'

#in the app/controllers/checkout_controller.rb
 def index
   @charge = Charge.new
 end

#in the app/views/checkout/index.html.erb

<%= form_for(@charge, url: charges_path, method: :post ) do |f| %>


  <% if @charge.errors.any? %>
    <div id="error_explanation">
  <h2><%= pluralize(@charge.errors.count, "error") %> prohibited this charge from being saved:</h2>

    <ul>
    <% @charge.errors.full_messages.each do |msg| %>
     <li><%= msg %></li>
    <% end %>
    </ul>
   </div>
 <% end %>

  <div class="title">
    <h1>shipment</h1>
  </div>

  <div class="large-12 columns">
    <%= f.text_field :name, placeholder: "name", maxlength: "20", class: "radius" %>
  </div>
  <div class="large-12 columns">
    <%= f.text_field :address, placeholder: "address", class: "radius" %>
  </div>
  <div class="large-12 columns">
    <%= f.text_field :email, placeholder: "email", class: "radius" %>
  </div>
  <hr>


  <%= f.submit "buy", class: "button green radius small expand" %>
 <% end %>


#in the app/controllers/charges_controller.rb

 def create
   @charge = Charge.new(id: "523dd8f6aef8784386000001", amount: 60000, livemode: false, created_at: 1379784950, status: "paid", currency: "MXN", description: "Pizza", reference_id: "9839-wolf_pack", failure_code: "none", failure_message: "none", name: params[:name], address: params[:address], email: params[:email], ship_number: "5678sdf7sd5f6")
   @charge.save
   respond_with(@charge)
 end

#in the app/models/charge.rb
 validates :name, :address, :email, presence: true

Just for testing I filled some data with default values in the create method. In the form ('/checkout/pay') I filled :name, :address, :email, manually with data, but redirect me to the new_charge_path and tells me: Name can't be blank Address can't be blank Email can't be blank

There is some error with trying to get the params from the form in the html view?

You are using form_for view helper, according to rails conventions, the controller gets a nested hash params[:charg] with the charge attributes set in the form.

So, on your controller you must call:

@charge = Charge.new(name: params[:charge][:name], address: params[:charge][:address], email: params[:charge][:email])
