Grails controllers repeated code for all actions

阅读更多关于 Grails controllers repeated code for all actions

Imagine this controller: class exampleController{ def action1 = {} def action2 = {} def action3 = {} def action4 = {} def action5 = {} } I want to be able to return in all the action in this controller the same params. Imagining this: def user = session.user [user: user] Is there any way of doing this, besides writing all the same code on all the actions? The session.user return params is just an example. I don't wanna really return it. A simple solution is to put this code in a method and call it from each action class exampleController{ def action1 = {getModel()} def action2 = {getModel()}

Devise : Sign in from a controller

阅读更多关于 Devise : Sign in from a controller

How can I remove callbacks inserted by vendor code?

阅读更多关于 How can I remove callbacks inserted by vendor code?

A gem I am using inserts an after_save callback that I would like to remove. It seems to me it would be cleaner to delete a symbol from an array than to fix the problem with a monkeypatch. How can I access the array of callbacks? class UserSession < Authlogic::Session::Base # Don't use cookie AuthLogic behaviour skip_callback :persist, :persist_by_cookie skip_callback :after_save, :save_cookie skip_callback :after_destroy, :destroy_cookie end the after_save array is accessible via Model.after_save , it is an array of ActiveSupport::Callbacks::Callback objects. You could run this from within
