ActsAsConfirmable ================= acts_as_confirmable is useful when you want to know who ticked a check box and when they did so. This plugin treats a datetime attribute and an integer attribute as a boolean. This boolean can then be used as normal attribute in a check box (or in any part of the program) and when it is checked, the datetime records the moment and the integer records the id of the current user. It is assumed that there is a Users table and that the current user can be found at User.current_user. If the current user cannot be accessed then 1 is used as the id. Installation ============ $ cd vendor/plugins $ git checkout git://github.com/kumo/acts_as_confirmable/tree Usage ===== - On models where you want to be able to confirm X add a X_confirmed_at datetime and X_confirmed_by integer. - In the model put acts_as_confirmed :X - In the views add check boxes (check_box :X) Example ======= - create a new rails app $ rails confirm $ cd confirm - create the users table $ script/generate scaffold user name:string - create an items table with 3 confirmable fields $ script/generate scaffold item name:string started_confirmed_by:integer started_confirmed_at:datetime finished_confirmed_by:integer finished_confirmed_at:datetime ready_confirmed_by:integer ready_confirmed_at:datetime - add the plugin to the model class Item < ActiveRecord::Base acts_as_confirmable :started, :finished, :ready end - add 3 check boxes in items/new.html.erb and items/edit.html.erb <p> <%= f.label :started %><br /> <%= f.check_box :started %> </p> <p> <%= f.label :finished %><br /> <%= f.check_box :finished %> </p> <p> <%= f.label :ready %><br /> <%= f.check_box :ready %> </p> - show the confirmation info in items/list.html.erb <td><%=h item.started? %> <%= item.started_confirmer.name if item.started? %></td> - example of assigning a user to current_user class User < ActiveRecord::Base cattr_accessor :current_user end class ItemsController < ApplicationController before_filter :load_user protected def load_user User.current_user = User.find(:first) end end Available fields ================ If a model has the attributes started_confirmed_at and started_confirmed_by, then the plugin provides: * started? -- true if it has been confirmed by someone on a specific date * started -- same as above but is normally used by a check box tag * started= -- the assignment method that is used by the check box when posting * started_confirmer -- the user that confirmed it * started_at -- when it was confirmed Copyright (c) 2008 Rob Clarke (kumo), released under the MIT license
