CANDY WRAPPER
Use form objects with ease. Plugs into inherited_resources
easily:
# app/models/database_object.rb
class DatabaseObject < Persistence::Base
# ... persistence and relationships only ...
end
# app/controllers/database_objects_controller.rb
class DatabaseObjectsController < ApplicationController
inherit_resources
# for the parts of inherited_resources that actually persist models,
# ensure that persistence takes placed within a CandyWrapper::ModelWrapper
# form object. Those respond to save, assign_attributes, and update_attributes.
wrap_in_form_object!
end
# app/form_objects/database_object_form_object.rb
class DatabaseObjectFormObject < CandyWrapper::ModelWrapper
def complex_parameter=(database_object, parameter_value)
# do complex formatting here, probably for nested objects
# database_object will be saved by this point
end
# perform these actions before database_object is saved
before_wrapped_save :process_first_parameter
def process_first_parameter=(database_object, parameter_value)
# use normal accessors to set properties on database_object, it will be
# saved when all before_wrapped_saved methods are run
end
# there is no guarantee in the order that these will run, don't make them
# depend on each other!
end
Also, plug it into ActiveAdmin super-easily, which is where I typicallty use it!
ActiveAdmin.register Model do
wrap_in_form_object
end
