Rails - NoMethodError in Home#new

I have converted a front end project to the Rails environment, and I have used Material Design Lite to design the form fields. I am getting the following error:

NoMethodError in Home#new - undefined method `homes_path'

Can anyone help me fix the error?

routes.rb:

Rails.application.routes.draw do
  # For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html
  get '/home', to: 'home#index'
  get '/home/new', to: 'home#new'
  get 'home/:id', to: 'home#show'
end

new.html.erb:

<div class="container-div">
  <!-- Colored FAB button with ripple -->
  <button id="fab" class="mdl-button mdl-js-button mdl-button--fab mdl-js-ripple-effect mdl-button--colored">
    <i class="material-icons">add</i>
  </button>

  <div class="demo-card-wide mdl-card mdl-shadow--2dp">
    <div class="mdl-card__title" id="text-div">
      <h2 id="title-text" class="mdl-card__title-text">CAMPAIGN</h2>
      <br>
      <br>
      <span id="success">Success!</span>
    </div>
    <div class="mdl-card__supporting-text">

      <%= form_for(@home) do |f| %>
          <div class="mdl-textfield mdl-js-textfield mdl-textfield--floating-label">
            <%= f.text_field_tag :campaign_name,nil,:class => "mdl-textfield__input"%>
            <label class="mdl-textfield__label" for="campaign_name">Campaign Name</label>
          </div>

          <div class="mdl-textfield mdl-js-textfield mdl-textfield--floating-label">
            <%= f.text_field_tag :phone_number_receiver,nil,:class => "mdl-textfield__input",:type => "number" %>
            <label class="mdl-textfield__label" for="phone_number_receiver">Phone Number for recipient</label>
            <span class="mdl-textfield__error">Input is not a number!</span>
          </div>

          <div class="mdl-textfield mdl-js-textfield mdl-textfield--floating-label">
            <%= f.text_field_tag :start_date,nil,:class => "mdl-textfield__input"%>
            <label class="mdl-textfield__label" for="start_date" id="start-date-label">Enter start date</label>
          </div>


          <div class="mdl-textfield mdl-js-textfield mdl-textfield--floating-label">
            <%= f.text_field_tag :end_date,nil,:class => "mdl-textfield__input"%>
            <label class="mdl-textfield__label" for="end_date" id="end-date-label">Enter end date</label>
          </div>

          <div class="mdl-textfield mdl-js-textfield mdl-textfield--floating-label">
            <%= f.text_field_tag :start_time,nil,:class => "mdl-textfield__input"%>
            <label class="mdl-textfield__label" for="start_time" id="start-time-label">Enter time</label>
          </div>

          <div class="mdl-textfield mdl-js-textfield less-margin mdl-textfield--floating-label">
            <%= f.text_area_tag :sms_msg, nil,:class => "mdl-textfield__input", :rows => 8, :cols => 40 %>
            <label class="mdl-textfield__label" for="sms_msg">Text Message</label>

          </div>

          <div class="mdl-textfield mdl-js-textfield mdl-textfield--floating-label">
            <%= text_field_tag :break_msg,"1",:class => "mdl-textfield__input"%>
            <label class="mdl-textfield__label" for="break_msg">Number of Pages</label>
          </div>
      <%end%>


    </div>
  </div>
</div>

home_controller.rb:

class HomeController < ApplicationController
  def index
    @campaigns = Home.all
  end

  def new
    @home = Home.new
  end

  def show
    @campaign = Home.find(params[:id])
  end
end

PS: The form field for :break_msg is not a part of the model Home.

Looks like your form is pointing to a route (homes_path or /homes) that doesn't exist. You need to create a POST route and corresponding controller action.

post '/home', to: 'home#create', as: :homes

Keep in mind, the as: :homes may be optional. Run rake routes to verify.

And for the controller action, something like this:

def create
  @home = Home.create(home_params)
  ...
end

For more info, check out the Rails docs on controllers.

EDIT: Also, you're using text_field_tag and text_area_tag in your form but since you're using an ActiveRecord object (@home) then you don't need the _tag. So, just f.text_field and f.text_area.

Lastly, you should use the resources helper instead of manually creating the "home" routes. Read through the Rails docs on routing for more info and customization options (e.g. getting /home instead of /homes when using resources :homes).

this issue seems similar to an issue I had previously: undefined method `wikis_path'

try renaming your controller to homes_controller.rb. This will create a bunch of errors that you will need to clean up (such as actually changing class HomeController < ApplicationController to class HomesController < ApplicationController as well as fixing your routes). This should address the issue of not having the homes_path route.
