如果条件不适用于&&运算符

Question

还显示了其中receive_by_admin为True的订单链接。

if order.payment_status == 'Paid' && order.received_by_admin != 'true'
   link_to "Payment Received", "orders/#{order.id}/?payment_status=Paid", class: "member_link", method: :put
end

Answer 1

可能是因为received_by_admin是布尔值吗？所以

order.payment_status == 'Paid' && order.received_by_admin != true

或更简单

order.payment_status == 'Paid' && !order.received_by_admin

这里的重点是true != 'true'
