Rails：在控制器的所有动作中可见的属性

Question

How can i create an attribute in a controller class, that can be seen inside all the actions and all the view related to this controller? thanks

Answer 1

在Controller中创建一个instance variable ，并确保为该变量提供attr_accessor ，以便所有视图都可以访问它。

Answer 2

Create before filter in your controller

For Example:

before_filter :example

def example

@variable = true

end

Now @variable is accessible in every action as well as views
