Rails ActionController Execute Same Code for Every Action
To the rails experts out there I was wondering where/how you would execute the same code for every action in your web application? If you can point me to an article or provide a short code snippet I would greatly appreciate it.
Thanks in advance to an开发者_StackOverflowyone who can help.
Use a filter in your ApplicationController to run the code for every action in your application. All your controllers descend from ApplicationController, so putting the filter there will ensure the filter gets run.
class ApplicationController
before_filter :verify_security_token
def verify_security_token; puts "Run"; end;
end
It sounds to me like you're talking about filters.
class MyController < ActionController::Base
before_filter :execute_this_for_every_action
def index
@foo = @bar
end
def new
@foo = @bar.to_s
end
def execute_this_for_every_action
@bar = :baz
end
end
You can put the filter on the ApplicationController, too, if you want every controller to run it.
before_filter
if you want the code to be executed "before" each action.If you want the action to be declared each time you use it, you can put it in
ApplicationController
and call the method in any controller.
Another approach is to use helpers like:
module PersonHelper
def eat
{.. some code ..}
end
end
And in your controller:
class MyController < ActionController::Base
include PersonHelper
def index
eat
end
end
