無法從新狀態過渡 - 等待退款詳細信息狀態Rails Statemachine Gem --- Pluginaweek

Question

無法理解通過我收到此錯誤StateMachine :: InvalidTransition：無法通過transition_details_not_found從新：（原因（S） ：國家不能通過「找不到退款詳情」）過渡

state_machine :initial => :new do  
    event :all_products_received do 
     transition [:new, :pending_refund_details, :canceled] => :pending_payment 
    end 

event :refund_details_not_found do 
    transition :new => :pending_refund_details 
end 

event :order_return_canceled do 
    transition :new => :canceled 
end 

event :mistaked_canceled do 
    transition :canceled => :buyer_dispatched 
end 

event :payment_made do 
    transition :pending_payment => :payment_complete 
end 

before_transition :to => :canceled do |return1| 
    return1.total = 0 
end 

before_transition :to => :pending_payment do |return1| 
    return1.pending_on = Time.now 
end 

before_transition :to => :payment_complete do |return1| 
    return1.completed_on = Time.now 
end 

end 

我打電話之前的過渡保存

我測試你的代碼，本身我沒有得到任何錯誤：

require 'state_machine' 

class Thing 
    attr_accessor :state 

    state_machine :initial => :new do 
    event :refund_details_not_found do 
     transition :new => :pending_refund_details 
    end 
    end 
end 

t = Thing.new 
puts t.state 
#=> new 
t.refund_details_not_found 
puts t.state 
#=> pending_refund_details 

我建議檢查，如果你有一些其他因素的干擾，如：Rails的驗證，其他的回調或before_transition S，超執行state_machine已經等
