Form submit button is calling controller's index function - ruby-on-rails

Question

The author built a UPS scaffold and rails created the model as up instead of ups. I've hacked some solutions in to make it work, but I can't get the create method to work when called from the new form. Rails calls the index function and no new object is created.
ups_controller.rb
def create
#up = Ups.new(params[:up])
respond_to do |format|
if #up.save
format.html { redirect_to #up, notice: 'Up was successfully created.' }
format.json { render json: #up, status: :created, location: #up }
else
format.html { render action: "new" }
format.json { render json: #up.errors, status: :unprocessable_entity }
end
end
end
def new
#up = Ups.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: #up }
end
end
ups/form.html.erb
<%= form_for(#up) do |f| %>
<table class="table table-striped table-bordered">
<tr>
<th>name</th>
<td><%= f.text_field :name %></td>
</tr>
<tr>
<th>attr</th>
<td><%= f.select :attr_id, options_from_collection_for_select(Attr.order(:name).where(:major => true).all, "id", "name", #up.attr_id) %></td>
</tr>
<tr>
<th>Action</th>
<td><%= f.submit "Submit New UPS" %></td>
</tr>
</table>
<% end %>
routes.rb
resources :ups
match 'ups/create' => 'ups#create'
match 'ups/index' => 'ups#index'
match 'pdus/link_all_ups' => 'pdus#link_all_ups'
Here is the button that calls the new method of the ups_controller:
<%= link_to 'Enter New UPS', new_ups_path, :class => "btn btn-success pull-right" %>
rake routes
ups GET /ups(.:format) ups#index
POST /ups(.:format) ups#create
new_up GET /ups/new(.:format) ups#new
edit_up GET /ups/:id/edit(.:format) ups#edit
up GET /ups/:id(.:format) ups#show
PUT /ups/:id(.:format) ups#update
DELETE /ups/:id(.:format) ups#destroy
ups_index /ups/index(.:format) ups#index
Thanks for any advice.

You also want to make sure rails is sending a Post request like this:
<%= form_for #up, :url=> ups_path, :method => :post do |f| %>
My guess is that your url is correct but rails in sending it as a get instead of a post. As you can see from your routes, the index and create action both have the same url and the only difference is the get/post.
ups GET /ups(.:format) ups#index
POST /ups(.:format) ups#create
