Rails 4 before_action, pass parameters to invoked method

Question

I have the following code:

class SupportsController < ApplicationController   before_action :set_support, only: [:show, :edit, :update, :destroy]   .... 

Is it possible to pass a string to the method set_support to be applied for all 4 view methods? Is it possible to pass a different string to the method set_support for each method in the view?

Answer 1

before_action only: [:show, :edit, :update, :destroy] do   set_support("value") end 

Answer 2

You can use a lambda:

class SupportsController < ApplicationController   before_action -> { set_support("value") },      only: [:show, :edit, :update, :destroy]   ...
