dm-parse

A DataMapper extension for Parse, include an adapter and some types for Parse.

Installation

Include in your Gemfile:

gem "dm-parse"

Or just gem install:

gem install dm-parse

Usage

To setup the adapter:

DataMapper.setup(:default, adapter: :parse, app_id: "your-id", api_key: "your-rest-api-key")

To setup with Master Key:

DataMapper.setup(:default, adapter: :parse, app_id: "your-id", api_key: "your-master-key", master: true)

To define model for parse, use is :parse:

class Article
  include DataMapper::Resource

  is :parse # it defines id, created_at and updated_at for you

  property :title,      String
  property :body,       Text
  property :rank,       Integer
  property :closed_at,  ParseDate # Date type for Parse

  has n, :comments
end

class Comment
  include DataMapper::Resource

  is :parse

  property :body,       Text

  belongs_to :article
end

To define a user model, use is :parse_user:

class User
  include DataMapper::Resource

  # more than :parse, it also defines username, password and email.
  # it also sets the default storage_names to "_User"
  is :parse_user
  storage_names[:master] = "_User"
end

By this, you can use User.authenticate(username, password) to sign in, and use User.request_password_reset(email) to reset password.

Special properties for Parse

ParseKey: the property for objectId, is :parse will define it for you.
ParsePointer: the pointer, you just need to give it objectId value.
ParseDate: the date, use it like you use DateTime.
ParseFile: the file, give it an IO object from web form, it will be uploaded, and it will be loaded as a URI object.
