Overview

Spaceship::Base is the superclass for models in Apple Developer Portal. It’s mainly responsible for mapping responses to objects.

A class-level attribute ‘client` is used to maintain the spaceship which we are using to talk to ADP.

Example of creating a new ADP model:

class Widget < Spaceship::Base
  attr_accessor :id, :name, :foo_bar, :wiz_baz
  attr_mapping({
    'name' => :name,
    'fooBar' => :foo_bar,
    'wizBaz' => :wiz_baz
  })
end

When you want to instantiate a model pass in the parsed response: ‘Widget.new(widget_json)`

Constructor Details

#initialize(attrs = {}, existing_client = nil) ⇒ Base

The initialize method accepts a parsed response from Apple and sets all attributes that are defined by ‘attr_mapping`

Do not override ‘initialize` in your own models.

  end
  self.raw_data = DataHash.new(attrs)

end

Instance Attribute Details

#client ⇒ Spaceship::Client (readonly)

Returns The current spaceship client used by the model to make requests.

Returns:

  • (Spaceship::Client) —

    The current spaceship client used by the model to make requests.

end

#raw_data ⇒ Hash/Array

Returns Holds the raw data we got from Apple’s server to use it later.

Returns:

  • (Hash/Array) —

    Holds the raw data we got from Apple’s server to use it later

Class Method Details

.attr_accessor(*vars) ⇒ Object

From stackoverflow.com/questions/2487333/fastest-one-liner-way-to-list-attr-accessors-in-ruby This will store a list of defined attr_accessors to easily access them when inspecting the values

# File 'spaceship/lib/spaceship/base.rb', line 247

def self.attr_accessor(*vars)
  @attributes ||= []
  @attributes.concat(vars)
  super(*vars)
end

.attr_mapping(attr_map = nil) ⇒ Object

Defines the attribute mapping between the response from Apple and our model objects. Keys are to match keys in the response and the values are to match attributes on the model.

Example of using ‘attr_mapping`

class Widget < Spaceship::Base
  attr_accessor :id, :name, :foo_bar, :wiz_baz
  attr_mapping({
    'name' => :name,
    'fooBar' => :foo_bar,
    'wizBaz' => :wiz_baz
  })
end

  @attributes + par
end

.factory(attrs, existing_client = nil) ⇒ Object

The factory class-method. This should only be used or overridden in very specific use-cases

The only time it makes sense to use or override this method is when we want a base class to return a sub-class based on attributes.

Here, we define the method to be the same as ‘Spaceship::Base.new(attrs)`, be it should be used only by classes that override it.

Example:

Certificate.factory(attrs)
#=> #<PushCertificate ... >

# File 'spaceship/lib/spaceship/base.rb', line 209

def factory(attrs, existing_client = nil)
  self.new(attrs, existing_client)
end

.mapping_module(attr_mapping) ⇒ Module

Binds attributes getters and setters to underlying data returned from the API. Setting any properties will alter the ‘raw_data` hash.

Returns:

  • (Module) —

    with the mapped getters and setters defined. Can be ‘include`, `extend`, or `prepend` into a class or object

      setter = "#{dest}=".to_sym

      define_method(getter) do
        raw_data.get(*source.split('.'))
      end

      define_method(setter) do |value|
        self.raw_data ||= DataHash.new({})
        raw_data.set(source.split('.'), value)
      end
    end
  end
end

.method_missing(method_sym, *args, &block) ⇒ Object

Call a method to return a subclass constant.

If ‘method_sym` is an underscored name of a class, return the class with the current client passed into it. If the method does not match, NoMethodError is raised.

Example:

Certificate.production_push
#=> Certificate::ProductionPush

ProvisioningProfile.ad_hoc
#=> ProvisioningProfile::AdHoc

ProvisioningProfile.some_other_method
#=> NoMethodError: undefined method `some_other_method' for ProvisioningProfile
