Empty_Cart doesn't work, cart session not destroyed and keeps directing to carts/destroy.html.erb in views, otherwise shown as Template Missing

I am learning Agile Web Development with Rails(4th), undergoing iteration E3: Finishing the cart. When trying to add a empty cart button, I get an error

Template is missing Missing template carts/destroy, application/destroy with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :raw, :ruby, :jbuilder, :coffee]}. Searched in: * "/Users/anil20787/workspace/railsdir/depot/app/views"

Basically, i get the exact same code as this question asked.

So what I did was, trying to edit the set_cartpart which is underbefore action. Unfortunately, it didn't work out.

Therefore I created a carts.destroy.html.erb file as wanted, and I add a redirecting to my store_url in this html, here is the content:

<meta charset="UTF-8">
<meta http-equiv="refresh" content="1;url= store_url">

And it directs to my store as expected, the PROBLEM is the cart is NOT destroyed. And when I add a new items in the cart, it was still the old cart.

For convenience, here is destroy in cart_controller:

def destroy
  @cart = current_cart
  @cart.destroy
  @session[:cart_id] = nil

 respond_to do |format|
  format.html { redirect_to store_url, notice: 'Your cart is currently empty' }
  format.json { head :no_content }
 end
end

here is empty cart button:

<%=  button_to 'Empty cart', cart_path(@cart), :method => :delete,
 :confirm => 'Are you sure?', :remote=> true %>

Maybe in my cart_controller, the session deleting didn't work? Or how to make empty cart work?

Really appreciate your help!!

Here is the server log file:

Solution

  • Filter chain halted as :set_cart rendered or redirected

    Main issue is here. You can set it to as follows: 

    before_action :set_cart ,:only => only: [:show, :edit, :update, :destroy]

    Using this set cart method call only before show and edit actions.
