It implements object-relational mapping for REST web services to provide transparent proxying capabilities between a client (ActiveResource) and a RESTful service (which is provided by Simply RESTful routing in ActionController::Resources). == Philosophy Active Resource attempts to provide a coherent wrapper object-relational mapping for REST web services. It follows the same philosophy as Active Record, in that one of its prime aims is to reduce the amount of code needed to map to these resources. This is made possible by relying on a number of code- and protocol-based conventions that make it easy for Active Resource to infer complex relations and structures. These conventions are outlined in detail in the documentation for ActiveResource::Base. == Overview Model classes are mapped to remote REST resources by Active Resource much the same way Active Record maps model classes to database tables. When a request is made to a remote resource, a REST XML request is generated, transmitted, and the result received and serialized into a usable Ruby object. == Download and installation The latest version of Active Resource can be installed with RubyGems: % [sudo] gem install activeresource Source code can be downloaded as part of the Rails project on GitHub * https://github.com/rails/rails/tree/3-2-stable/activeresource === Configuration and Usage Putting Active Resource to use is very similar to Active Record. It's as simple as creating a model class that inherits from ActiveResource::Base and providing a site class variable to it: class Person < ActiveResource::Base self.site = "http://api.people.com:3000" end Now the Person class is REST enabled and can invoke REST services very similarly to how Active Record invokes life cycle methods that operate against a persistent store. # Find a person with id = 1 ryan = Person.find(1) Person.exists?(1) # => true As you can see, the methods are quite similar to Active Record's methods for dealing with database records. But rather than dealing directly with a database record, you're dealing with HTTP resources (which may or may not be database records). ==== Protocol Active Resource is built on a standard XML format for requesting and submitting resources over HTTP. It mirrors the RESTful routing built into Action Controller but will also work with any other REST service that properly implements the protocol. REST uses HTTP, but unlike "typical" web applications, it makes use of all the verbs available in the HTTP specification: * GET requests are used for finding and retrieving resources. * POST requests are used to create new resources. * PUT requests are used to update existing resources. * DELETE requests are used to delete resources. For more information on how this protocol works with Active Resource, see the ActiveResource::Base documentation; for more general information on REST web services, see the article here[http://en.wikipedia.org/wiki/Representational_State_Transfer]. ==== Find Find requests use the GET method and expect the XML form of whatever resource/resources is/are being requested. So, for a request for a single element, the XML of that item is expected in response: # Expects a response of # # 1value1.. # # for GET http://api.people.com:3000/people/1.xml # ryan = Person.find(1) The XML document that is received is used to build a new object of type Person, with each XML element becoming an attribute on the object. ryan.is_a? Person # => true ryan.attribute1 # => 'value1' Any complex element (one that contains other elements) becomes its own object: # With this response: # # 1value1value2 # # for GET http://api.people.com:3000/people/1.xml # ryan = Person.find(1) ryan.complex # => ryan.complex.attribute2 # => 'value2' Collections can also be requested in a similar fashion # Expects a response of # # # 1Ryan # 2Jim # # # for GET http://api.people.com:3000/people.xml # people = Person.all people.first # => 'Ryan' ...> people.last # => 'Jim' ...> ==== Create Creating a new resource submits the XML form of the resource as the body of the request and expects a 'Location' header in the response with the RESTful URL location of the newly created resource. The id of the newly created resource is parsed out of the Location response header and automatically set as the id of the ARes object. # Ryan # # is submitted as the body on # # POST http://api.people.com:3000/people.xml # # when save is called on a new Person object. An empty response is # is expected with a 'Location' header value: # # Response (201): Location: http://api.people.com:3000/people/2 # ryan = Person.new(:first => 'Ryan') ryan.new? # => true ryan.save # => true ryan.new? # => false ryan.id # => 2 ==== Update 'save' is also used to update an existing resource and follows the same protocol as creating a resource with the exception that no response headers are needed -- just an empty response when the update on the server side was successful. # Ryan # # is submitted as the body on # # PUT http://api.people.com:3000/people/1.xml # # when save is called on an existing Person object. An empty response is # is expected with code (204) # ryan = Person.find(1) ryan.first # => 'Ryan' ryan.first = 'Rizzle' ryan.save # => true ==== Delete Destruction of a resource can be invoked as a class and instance method of the resource. # A request is made to # # DELETE http://api.people.com:3000/people/1.xml # # for both of these forms. An empty response with # is expected with response code (200) # ryan = Person.find(1) ryan.destroy # => true ryan.exists? # => false Person.delete(2) # => true Person.exists?(2) # => false == License Active Resource is released under the MIT license. == Support API documentation is at * http://api.rubyonrails.org Bug reports and feature requests can be filed with the rest for the Ruby on Rails project here: * https://github.com/rails/rails/issues You can find more usage information in the ActiveResource::Base documentation. activeresource-3.2.16/checksums.yaml.gz0000444000175000017500000000041512247655230017446 0ustar ondrejondrej#Re9V0 D"Od-9PB?3:s?/+eY`h ^ӱTv~r`JCE6@VsD8LjZN4ϿbAlSxrS,[hhΈ`YC (+ ՛@2V* $ Bg5 %d %s %d (%.1fms)" % [result.code, result.message, result.body.to_s.length, event.duration] end def logger ActiveResource::Base.logger end end end ActiveResource::LogSubscriber.attach_to :active_resourceactiveresource-3.2.16/lib/active_resource/validations.rb0000644000175000017500000001211312247655230022750 0ustar ondrejondrejrequire 'active_support/core_ext/array/wrap' require 'active_support/core_ext/object/blank' module ActiveResource class ResourceInvalid < ClientError #:nodoc: end # Active Resource validation is reported to and from this object, which is used by Base#save # to determine whether the object in a valid state to be saved.

To map resources # to Ruby objects, Active Resource only needs a class name that corresponds to the resource name (e.g., the class # Person maps to the resources people, very similarly to Active Record) and a +site+ value, which holds the # URI of the resources. # # class Person < ActiveResource::Base # self.site = "http://api.people.com:3000/" # end # # Now the Person class is mapped to RESTful resources located at http://api.people.com:3000/people/, and # you can now use Active Resource's life cycle methods to manipulate resources. In the case where you already have # an existing model with the same name as the desired RESTful resource you can set the +element_name+ value. # # class PersonResource < ActiveResource::Base # self.site = "http://api.people.com:3000/" # self.element_name = "person" # end # # If your Active Resource object is required to use an HTTP proxy you can set the +proxy+ value which holds a URI. # # class PersonResource < ActiveResource::Base # self.site = "http://api.people.com:3000/" # self.proxy = "http://user:password@proxy.people.com:8080" # end # # # == Life cycle methods # # Active Resource exposes methods for creating, finding, updating, and deleting resources # from REST web services. # # ryan = Person.new(:first => 'Ryan', :last => 'Daigle') # ryan.save # => true # ryan.id # => 2 # Person.exists?(ryan.id) # => true # ryan.exists? # => true # # ryan = Person.find(1) # # Resource holding our newly created Person object # # ryan.first = 'Rizzle' # ryan.save # => true # # ryan.destroy # => true # # As you can see, these are very similar to Active Record's life cycle methods for database records. # You can read more about each of these methods in their respective documentation. # # === Custom REST methods # # Since simple CRUD/life cycle methods can't accomplish every task, Active Resource also supports # defining your own custom REST methods. To invoke them, Active Resource provides the get, # post, put and \delete methods where you can specify a custom REST method # name to invoke. # # # POST to the custom 'register' REST method, i.e. POST /people/new/register.json. # Person.new(:name => 'Ryan').post(:register) # # => { :id => 1, :name => 'Ryan', :position => 'Clerk' } # # # PUT an update by invoking the 'promote' REST method, i.e. PUT /people/1/promote.json?position=Manager. # Person.find(1).put(:promote, :position => 'Manager') # # => { :id => 1, :name => 'Ryan', :position => 'Manager' } # # # GET all the positions available, i.e. GET /people/positions.json. # Person.get(:positions) # # => [{:name => 'Manager'}, {:name => 'Clerk'}] # # # DELETE to 'fire' a person, i.e. DELETE /people/1/fire.json. # Person.find(1).delete(:fire) # # For more information on using custom REST methods, see the # ActiveResource::CustomMethods documentation. # # == Validations # # You can validate resources client side by overriding validation methods in the base class. # # class Person < ActiveResource::Base # self.site = "http://api.people.com:3000/" # protected # def validate # errors.add("last", "has invalid characters") unless last =~ /[a-zA-Z]*/ # end # end # # See the ActiveResource::Validations documentation for more information. # # == Authentication # # Many REST APIs will require authentication, usually in the form of basic # HTTP authentication. Authentication can be specified by: # # === HTTP Basic Authentication # * putting the credentials in the URL for the +site+ variable. # # class Person < ActiveResource::Base # self.site = "http://ryan:password@api.people.com:3000/" # end # # * defining +user+ and/or +password+ variables # # class Person < ActiveResource::Base # self.site = "http://api.people.com:3000/" # self.user = "ryan" # self.password = "password" # end # # For obvious security reasons, it is probably best if such services are available # over HTTPS. # # Note: Some values cannot be provided in the URL passed to site. e.g. email addresses # as usernames. In those situations you should use the separate user and password option. # # === Certificate Authentication # # * End point uses an X509 certificate for authentication. See ssl_options= for all options. # # class Person < ActiveResource::Base # self.site = "https://secure.api.people.com/" # self.ssl_options = {:cert => OpenSSL::X509::Certificate.new(File.open(pem_file)) # :key => OpenSSL::PKey::RSA.new(File.open(pem_file)), # :ca_path => "/path/to/OpenSSL/formatted/CA_Certs", # :verify_mode => OpenSSL::SSL::VERIFY_PEER} # end # # # == Errors & Validation # # Error handling and validation is handled in much the same manner as you're used to seeing in # Active Record. Both the response code in the HTTP response and the body of the response are used to # indicate that an error occurred. # # === Resource errors # # When a GET is requested for a resource that does not exist, the HTTP 404 (Resource Not Found) # response code will be returned from the server which will raise an ActiveResource::ResourceNotFound # exception. # # # GET http://api.people.com:3000/people/999.json # ryan = Person.find(999) # 404, raises ActiveResource::ResourceNotFound # # # 404 is just one of the HTTP error response codes that Active Resource will handle with its own exception. The # following HTTP response codes will also result in these exceptions: # # * 200..399 - Valid response. No exceptions, other than these redirects: # * 301, 302, 303, 307 - ActiveResource::Redirection # * 400 - ActiveResource::BadRequest # * 401 - ActiveResource::UnauthorizedAccess # * 403 - ActiveResource::ForbiddenAccess # * 404 - ActiveResource::ResourceNotFound # * 405 - ActiveResource::MethodNotAllowed # * 409 - ActiveResource::ResourceConflict # * 410 - ActiveResource::ResourceGone # * 422 - ActiveResource::ResourceInvalid (rescued by save as validation errors) # * 401..499 - ActiveResource::ClientError # * 500..599 - ActiveResource::ServerError # * Other - ActiveResource::ConnectionError # # These custom exceptions allow you to deal with resource errors more naturally and with more precision # rather than returning a general HTTP error. For example: # # begin # ryan = Person.find(my_id) # rescue ActiveResource::ResourceNotFound # redirect_to :action => 'not_found' # rescue ActiveResource::ResourceConflict, ActiveResource::ResourceInvalid # redirect_to :action => 'new' # end # # When a GET is requested for a nested resource and you don't provide the prefix_param # an ActiveResource::MissingPrefixParam will be raised. # # class Comment < ActiveResource::Base # self.site = "http://someip.com/posts/:post_id/" # end # # Comment.find(1) # # => ActiveResource::MissingPrefixParam: post_id prefix_option is missing # # === Validation errors # # Active Resource supports validations on resources and will return errors if any of these validations fail # (e.g., "First name can not be blank" and so on). These types of errors are denoted in the response by # a response code of 422 and an XML or JSON representation of the validation errors. The save operation will # then fail (with a false return value) and the validation errors can be accessed on the resource in question. # # ryan = Person.find(1) # ryan.first # => '' # ryan.save # => false # # # When # # PUT http://api.people.com:3000/people/1.json # # or # # PUT http://api.people.com:3000/people/1.json # # is requested with invalid values, the response is: # # # # Response (422): # # First cannot be empty # # or # # {"errors":["First cannot be empty"]} # # # # ryan.errors.invalid?(:first) # => true # ryan.errors.full_messages # => ['First cannot be empty'] # # Learn more about Active Resource's validation features in the ActiveResource::Validations documentation. # # === Timeouts # # Active Resource relies on HTTP to access RESTful APIs and as such is inherently susceptible to slow or # unresponsive servers. In such cases, your Active Resource method calls could \timeout. You can control the # amount of time before Active Resource times out with the +timeout+ variable. # # class Person < ActiveResource::Base # self.site = "http://api.people.com:3000/" # self.timeout = 5 # end # # This sets the +timeout+ to 5 seconds. You can adjust the +timeout+ to a value suitable for the RESTful API # you are accessing. It is recommended to set this to a reasonably low value to allow your Active Resource # clients (especially if you are using Active Resource in a Rails application) to fail-fast (see # http://en.wikipedia.org/wiki/Fail-fast) rather than cause cascading failures that could incapacitate your # server. # # When a \timeout occurs, an ActiveResource::TimeoutError is raised. You should rescue from # ActiveResource::TimeoutError in your Active Resource method calls. # # Internally, Active Resource relies on Ruby's Net::HTTP library to make HTTP requests. Setting +timeout+ # sets the read_timeout of the internal Net::HTTP instance to the same value. The default # read_timeout is 60 seconds on most Ruby implementations. class Base ## # :singleton-method: # The logger for diagnosing and tracing Active Resource calls. cattr_accessor :logger class_attribute :_format class << self # Creates a schema for this resource - setting the attributes that are # known prior to fetching an instance from the remote system. # # The schema helps define the set of known_attributes of the # current resource. # # There is no need to specify a schema for your Active Resource.

One thing that has always been a pain with remote web services is testing. The HttpMock # class makes it easy to test your Active Resource models by creating a set of mock responses to specific # requests. # # To test your Active Resource model, you simply call the ActiveResource::HttpMock.respond_to # method with an attached block. The block declares a set of URIs with expected input, and the output # each request should return. The passed in block has any number of entries in the following generalized # format: # # mock.http_method(path, request_headers = {}, body = nil, status = 200, response_headers = {}) # # * http_method - The HTTP method to listen for. This can be +get+, +post+, +put+, +delete+ or # +head+. # * path - A string, starting with a "/", defining the URI that is expected to be # called. # * request_headers - Headers that are expected along with the request. This argument uses a # hash format, such as { "Content-Type" => "application/json" }. This mock will only trigger # if your tests sends a request with identical headers. # * body - The data to be returned. This should be a string of Active Resource parseable content, # such as Json. # * status - The HTTP response code, as an integer, to return with the response. # * response_headers - Headers to be returned with the response. Uses the same hash format as # request_headers listed above. # # In order for a mock to deliver its content, the incoming request must match by the http_method, # +path+ and request_headers. If no match is found an +InvalidRequestError+ exception # will be raised showing you what request it could not find a response for and also what requests and response # pairs have been recorded so you can create a new mock for that request. # # ==== Example # def setup # @matz = { :person => { :id => 1, :name => "Matz" } }.to_json # ActiveResource::HttpMock.respond_to do |mock| # mock.post "/people.json", {}, @matz, 201, "Location" => "/people/1.json" # mock.get "/people/1.json", {}, @matz # mock.put "/people/1.json", {}, nil, 204 # mock.delete "/people/1.json", {}, nil, 200 # end # end # # def test_get_matz # person = Person.find(1) # assert_equal "Matz", person.name # end # class HttpMock class Responder #:nodoc: def initialize(responses) @responses = responses end [ :post, :put, :get, :delete, :head ].each do |method| # def post(path, request_headers = {}, body = nil, status = 200, response_headers = {}) # @responses[Request.new(:post, path, nil, request_headers)] = Response.new(body || "", status, response_headers) # end module_eval <<-EOE, __FILE__, __LINE__ + 1 def #{method}(path, request_headers = {}, body = nil, status = 200, response_headers = {}) request = Request.new(:#{method}, path, nil, request_headers) response = Response.new(body || "", status, response_headers) delete_duplicate_responses(request) @responses << [request, response] end EOE end private def delete_duplicate_responses(request) @responses.delete_if {|r| r[0] == request } end end class << self # Returns an array of all request objects that have been sent to the mock.
