Rails Create Action Not Working

问题

My simple form is not doing a POST. I've been looking at this and haven't been able to see what is wrong (I'm sure it's in my routes). Here's what I have:

view:

views/buyers/new.html.erb

    <%= form_for(@buyer) do |f| %>
            <%= f.text_field :phone %><br />
            <%= f.text_field :make %><br />
            <%= f.text_field :model %><br />
            <%= f.submit %>
          <% end %>

controller:

BuyersController
  def new
    @title = "Welcome to Car Finder"
    @buyer = Buyer.new
  end 

  def create
    @buyer = Buyer.new(params[:buyer])
    if @buyer.save!
      redirect_to success
    else
      redirect_to :back
    end
   end

routes:

resources :buyers

rake routes:

                    buyers GET    /buyers(.:format)                buyers#index
                           POST   /buyers(.:format)                buyers#create
                 new_buyer GET    /buyers/new(.:format)            buyers#new
                edit_buyer GET    /buyers/:id/edit(.:format)       buyers#edit
                     buyer GET    /buyers/:id(.:format)            buyers#show
                           PUT    /buyers/:id(.:format)            buyers#update
                           DELETE /buyers/:id(.:format)            buyers#destroy

When I submit the form, it stays on the same page, never going to the create action. Below is from the log

Started GET "/?..[params]..."
Processing by BuyersController#new as HTML

Thanks for any help you can give

It is probably wise to restart your server. You're issue may lie in validations you have at your persistence level or in your buyer.rb file. Add this to the _form.html.erb:

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

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

Try to complete the request again. See if any errors are being thrown. Fix those.
