How to override Spree checkout forms and step flows?

Question

I'm using spree 2.0.0 in my application. I just want to know how i can edit spree checkout or how I can completely remove / disable any "Step" during Spree checkout process.

Any thoughts on this?

Answer 1

As Documentation says, you can use remove_checkout_step helper method (which is also much clearer than redefining whole checkout process), for example:

Spree::Order.class_eval do
  # ...
  remove_checkout_step :delivery
  # ...
end

Answer 2

I just found the solution. Here it is.

Step 1:Create app/models/order_decorator.rb file

Step 2: Copy following code in your order_decorator.rb 

Spree::Order.class_eval do
  checkout_flow do
    go_to_state :address
    #go_to_state :delivery
    go_to_state :payment, if: ->(order) {
      order.update_totals
      order.payment_required?
    }
    go_to_state :confirm, if: ->(order) { order.confirmation_required? }
    go_to_state :complete, if: ->(order) {
      (order.payment_required? && order.has_unprocessed_payments?) || !order.payment_required?
    }
    remove_transition from: :delivery, to: :confirm
  end
end

Example: if you want to remove delivery state just comment it out.You can comment out any step.

You can find more info in the documentation.
