facing issue in routes

I am using rail 4.2 and ruby 2.2.0p0, I need to submit form which belongs to user table, once the user authenticate and for authentication I am using devise, Do I need to create user controller and view manually or

I have created two directory named as my_devise one under controllers and other under views. I followed this for the approach which I took. I am getting "uninitalized constant MyDeviseController" error.Here is the list of files which I modified.

my_devise/registrations_controller.rb

class MyDevise::RegistrationsController < Devise::RegistrationsController

def update     @user = current_user     if @user.update_attributes(user_params)       # Handle a successful update.     else       redirect_to 'my_devise/registrations'     end   end

  private

    def user_params       params.require(:user).permit(:title, :font, :description,                                    :bgcolor)     end

end my_devise/registration.html.erb

<%= form_for :user, @user, :url => url_for(:controller => 'registrations', :action => 'update') do |u|%> <br > <p>     <%= u.label :title %><br>     <%= u.text_field :title %>   </p>

  <p>     <%= u.label :description %><br>     <%= u.text_field :description %>   </p>

  <p> <%= u.label :back_ground_color %><br>     <select name="bgcolor" id="bgcolor">         <option value="#FF3300">Orange</option>         <option value="#00FF00">Green</option>         <option value="#0000FF">Blue</option>         <option value="#FF0066">Pink</option>         <option value="#FFFF00">Yellow</option>         <option value="#FFFFFF">White</option>     </select>   </p>

  <p>     <%= u.label :font %><br>     <select name="font" id="font">         <option value="Times New Roman">Times new Roman</option>         <option value="Verdana">Verdana</option>         <option value="Arial">Arial</option>         <option value="sans-serif">serif</option>     </select>   </p>

<br >   <p>     <%= u.submit %>   </p>   <hr >   <div style="background: #{current_user.bg_color};"></div>   <div style="background-color:#{current_user.font.nil? ? '#FFFFFF' : current_user.font}">     This is the changes made in background   </div>

<div style="background-color:#{current_user.bgcolor.nil? ? '#FFFFFF' : current_user.bgcolor}">

  </div>

<% end %>
