Move serialization logic out of your model
Add this line to your application's Gemfile:
gem 'serialize'
And then execute:
$ bundle
Or install it yourself as:
$ gem install serialize
class UserSerializer < Serialize
# create a default serialization structure
structure do |user|
{
:name => user.name,
:gender => user.gender,
:email => user.email
}
end
# create a named serialization structure
structure :extended do |user|
{
:name => user.name,
:gender => user.gender,
:email => user.email,
:height => user.height,
:eye_color => user.eye_color,
:hair_color => user.hair_color
}
end
end
@app = App.find(params[:id])
# serialize your @app object with the default structure
AppSerializer(@app).to_json
# serialize your @app with a specified structure
AppSerializer.new(@app, :as => :extended)
# serializers can take an array of objects
@collection = App.all
AppSerializer.new(@collection, :as => :extended)
Enabling XML Support
# include dependencies
gem "activesupport"
gem "builder"
# require serialize/xml
require "serialize"
require "serialize/xml"
The serialize gem comes with JSON support enabled by default. XML has been disabled,
but can be required. You can also add your own forms of serialization.
To do this, you'll have to define a render method that accepts
*args. Because JSON and XML parsing pass different arguments *args
keeps the interface generic.
The hash to be serialized will be available as content.
Once your serialization format is built register it with by using the
Serialize.register method.
class Serialize::CSV < Serialize::Format
def render(*args)
if args.empty?
# turn hash into CSV
else
# do something else because arguments are passed in
end
end
end
Serialize.register "text/csv", Serialize::CSV
