Circular dependency detected while autoloading constant ORDER

I am building the application in Agile Development with Rails using Rails 4.1.0.

I looked up forums regarding the issue: Circular dependency detected while autoloading constant ORDER and found that it was a possible error because of the rails version and so updated mt Gemfile to use Rails 4.0.0

I get the error on this Line: <%= f.label :pay_type %>
<%= f.text_field :pay_type, ORDER::PAYMENT_TYPE, prompt: 'Select a payment method' %> <%= f.submit 'Place Order' %>

My Form is:

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

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

  <div class="field">
    <%= f.label :name %><br>
    <%= f.text_field :name, size: 40 %>
  </div>
  <div class="field">
    <%= f.label :address %><br>
    <%= f.text_area :address, rows: 3, cols: 40 %>
  </div>
  <div class="field">
    <%= f.label :email %><br>
    <%= f.text_field :email, size: 40 %>
  </div>
  <div class="field">
    <%= f.label :pay_type %><br>
    <%= f.text_field :pay_type, ORDER::PAYMENT_TYPE, prompt: 'Select a payment method' %>
  </div>
  <div class="actions">
    <%= f.submit 'Place Order' %>
  </div>
<% end %>

My Order.rb is:

class Order < ActiveRecord::Base
    PAYMENT_TYPE = ["Check", "Credit Card", "Purchase Order"]
end

I still get the error and am at my wits end to solving it since I have to submit this on Monday. :( :'( This is the full error stack trace. Can someone please help me!

It's not ORDER::PAYMENT_TYPE, it's Order::PAYMENT_TYPE. Notice the case on Order class. Using ORDER is going to raise NameError.

You also want to change the input helper used for :pay_type as Order::PAYMENT_TYPE returns an array. 

<%= f.select :pay_type, Order::PAYMENT_TYPE, include_blank: 'Select a payment method' %>

Also, you want to use the include_blank option instead of prompt for the "Select a payment method" text to appear as the default option.
