Hello fellow programmers, I have been working on a order management system. I finally have worked out all my errors except for one i cant get out. Once i delete a customer or a order i get a error message saying "Routing error".
Routing Error No route matches [POST] "/customers/2"

Destroy controller
def destroy
customer = Customer.find(params[:id]).destroy
flash[:notice] = "Subject '#{customer.first_name}' destroyed successfully"
redirect_to(:action => 'index')
end

The action destroy should look as something along the following lines:
def destroy
#customer = Customer.find(params[:id]
#customer.destroy
redirect_to(
customers_path,
notice: 'Customer successfully deleted'
)
end
Also edits to link:
<%= link_to("Delete", #customer, method: :delete, data: { confirm: "Are you sure?" }) %>
The problem in your case, is that you've defined variable customer, but use #customer in your url_helper (customer_path(#customer)).
Another thing (more important), is that you actually assign a customer a value, which is the result of deleting an object from database:
customer = Customer.find(params[:id]).destroy
Never do so.
Either do
Customer.find(params[:id]).destroy
or
#customer = Customer.find(params[:id])
#customer.destroy
