ruby - Rails flash.now within after_action -


The code speaks for itself on it.

This works ... 

  Classes some controllers & lt; ApplicationController DEF Index Flash. Now [: Warning] = 'Some have got bored!' End and << / code>

and this is not ( flash is empty) ... 

  class SomeController < ApplicationController after_action: test_flashdef index and def test_flash flash. Now [: Warning] = 'Some have got bored!'     
 --Eytmprop = "text"> 
 At the end of your  index  action rails, you  new  refer to the page, as if you have not specified anything different, after the index page is rendered,  after_action  is executed, it adds a callback after the index action is completed Will be said. Therefore,  test_flash  has no effect because it is too late and the index page has already been provided. 
 
 Edit: 
 
 If you want to call test_flash before rendering, you can override the  Render  method and do something like this: 
 
  def render * args test_flash super end

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
