ApplicationController Method with Equal Sign

Question

In Rails 4 I'm trying to do this:

class ApplicationController < ActionController::Base

 # does not work
  def x=(value)
    session[:x] = value
  end

  # I have to do this instead
  def set_x(value)
    session[:x] = value
  end 

end

When I try to call x = 1 from a child controller, I don't get an error, however the session variable doesn't get set. Running set_x 1 works as expected though.

Answer 1

我认为这是范围问题，而不是调用x = 1 ，请尝试调用self.x = 1 。
