如何在同一个控制器中将一个方法中实例变量的值传递给另一方法？

Question

我的控制器中的一种方法如下：

def new_equipment_matches_wanted
 #..........Big chucnk of code of about 7 to 8 lines and then..
 @receiver
end

现在，我在定义另一个方法，以访问此@receiver实例变量的值。 并且它将有一个单独的模板。

def send_receivers_to_admin
 #supposedly I am trying send @receiver values here
end 

我该如何实现？ 还是我应该在第二种方法中编写相同的代码，也只是为了访问该变量中的值？

Answer 1

实例变量（带有@）在所有控制器方法之间共享。

def new_equipment_matches_wanted
 #..........Big chucnk of code of about 7 to 8 lines and then..
 @receiver
end 
def send_receivers_to_admin
 @receiver.do_something
end

但是，正如塞尔吉奥所说，

“在请求之间传递实例变量是不可能的...控制器操作支持不同的请求”

那么您必须在两种方法上都加载@receiver ，您可以使用before_action

class CustomController < ActionController::Base
  before_action :load_receiver, only [:send_receivers_to_admin,:new_equipment_matches_wanted]

def new_equipment_matches_wanted
  @receiver.do_something
end 

def send_receivers_to_admin
 @receiver.do_something
end 

private

def load_receiver
    # Big chucnk of code of about 7 to 8 lines and then..
    @receiver
end
