state_machine :state, :initial => :awaiting_quote, use_transactions: false do
event :submit_quote do
transition :awaiting_quote => :awaiting_quote_acceptance,
if: :line_item_details_complete?
end
event :accept_quote do
transition :awaiting_quote_acceptance => :awaiting_final_invoice
end
event :decline_quote do
transition :awaiting_quote_acceptance => :awaiting_quote
end
event :submit_final_invoice do
transition :awaiting_final_invoice => :awaiting_order_acceptance,
if: :attachment?
end
event :accept_order do
transition :awaiting_order_acceptance => :order_placed
end
end
as you can see 2 of the state changes are dependent on line_item_details_complete? and attachment?
Now I am trying to implement the same state machine using dynamic state definitions
# Replace this with an external source (like a db)
def transitions
[
{ :awaiting_quote => :awaiting_quote_acceptance, :on => :submit_quote },
{ :awaiting_quote_acceptance => :awaiting_final_invoice, :on => :accept_quote },
{ :awaiting_quote_acceptance => :awaiting_quote, :on => :decline_quote },
{ :awaiting_final_invoice => :awaiting_order_acceptance, :on => :submit_final_invoice },
{ :awaiting_order_acceptance => :order_placed, :on => :accept_order }
# ...
]
end
# Create a state machine for this quotation instance dynamically based on the
# transitions defined from the source above
def machine
quotation = self
@machine ||= Machine.new(quotation, :initial => :awaiting_quote, :action => :save_state) do
quotation.transitions.each { |attrs| transition(attrs) }
end
end
# Save the state change
def save_state
self.save!
end
Now how do I use the same conditional state changes based on line_item_details_complete? and attachment? in the second approach? Thank you
I had a previous state machine like the following
as you can see 2 of the state changes are dependent on
line_item_details_complete?
andattachment?
