- The project is working toward a DSL that is very ActiveResource/ActiveRecord-like with some features stolen from other great libraries like DataMapper.
- We started working on this at a point when we felt we were pushing ActiveResource to its limits.
- We wanted a little more flexibility in terms of API coupling.
- We have plans to make Morpheus as flexible as possible in terms of query interface, and resource representation.
Additionally, Morpheus is built on top of Typhoeus and will be building in intuitive interfaces for working with parallel requests.
class Dummy < Morpheus::Base property :name property :created_at property :has_smarts belongs_to :thingy has_many :thingamabobs has_one :doohickey end
Morpheus uses ActiveModel and so has an interface that tries to not stray too far from the similar ActiveRecord interface.
@dummy = Dummy.new( :name => 'Dumb', :has_smarts => false, :thingy_id => 2) # => #<Dummy:0x1016858d8> @dummy.new_record? # => true @dummy.save # => POST http://example.com/dummies
Resources can be retrieved with as little as their classname and unique identifier.
@dummy = Dummy.find(1) # => GET http:example.com/dummies/1 @dummy.new_record? # => false @dummy.name # => 'Dumb'
Resources can be updated just in the same way you would expect from a Active* library.
@dummy.name = 'Dumber' # => 'Dumber' @dummy.save # => PUT http://example.com/dummies/1 @dummy.update_attributes(:has_smarts => true) # => PUT http://example.com/dummies/1
- Morpheus was originally conceived at a point when we needed ActiveResource with a little more.
Associations are a bit of that 'little more'.
@dummy.thingy # => GET http://example.com/thingies/2 @dummy.thingamabobs # => GET http://example.com/thingamabobs?dummy_id=1 @dummy.doohickey # => GET http://example.com/doohickey?dummy_id=1
- ARel has a beautiful query interface.
We have ported its method-chaining style to fit our query interface.
Dummy.all # => GET http://example.com/dummies Dummy.find(1,2,3) # => GET http://example.com/dummies?ids=1,2,3 Dummy.where(:name => 'Dumb') # => GET http://example.com/dummies?name=Dumb Dummy.where(:name => 'Dumb', :has_smarts => false) # => GET http://example.com/dummies?name=Dumb&has_smarts=false Dummy.limit(1) # => GET http://example.com/dummies?limit=1 Dummy.result_per_page = 25 # => 25 Dummy.page(3) # => GET http://example.com/dummies?limit=25&offset=50
