Minidoc

Minidoc is an extremely lightweight layer on top of the MongoDB client to make interacting with documents from Ruby more convenient.

We rely heavily on the MongoDB client, Virtus and ActiveModel to keep things as simple as possible.

• Interact with Ruby objects instead of hashes
• Full access to the powerful MongoDB client
• Thread safe (hopefully)
• Simple and easily extensible
• ActiveModel-compatible
• Validations
• Timestamp tracking (created_at/updated_at)
• Very basic associations (for reads)
• Conversion into immutable value objects
• Read-only records

• Custom query API (just use Mongo)
• Callbacks (just define a method like save and call super)

Add this line to your application's Gemfile:

gem "minidoc"

And then execute:

$ bundle

Or install it yourself as:

$ gem install minidoc

Minidoc.connection = Mongo::Client.new("mongodb://localhost")
Minidoc.database_name = "my_great_app_development"

class User < Minidoc
  include Minidoc::Timestamps

  attribute :name, String
  attribute :language, String
  timestamps!
end

user = User.create!(name: "Bryan", language: "Cobol")
User.count # => 1

user.language = "Lisp"
user.save!

user.set(language: "Fortran")

user.destroy
User.count # => 0

Just uses ActiveModel::Validations:

class User < Minidoc
  attribute :name, String

  validates :name, presence: true
end

user = User.new
user.valid? # => false
user.name = "Bryan"
user.valid? # => true

bryan = User.create(name: "Bryan").as_value
bryan.name #=> "Bryan"
bryan.name = "Brian" #=> NoMethodError

class Drink < Minidoc
  include Minidoc::Associations

  attribute :name, String

  belongs_to :user
end

bryan = User.create(name: "Bryan")
drink = Drink.create(name: "Paloma", user: bryan)
drink.user == bryan #=> true

Associations are also exposed as "bang methods" which raise a Minidoc::DocumentNotFoundError if the record pointed to by the foreign key is no longer present. (This can be useful in web frameworks where such exceptions automatically result in 404 responses.)

user.destroy
Drink.find(name: "Paloma").user!
# => Minidoc::DocumentNotFoundError

class DrinkEvents < Minidoc::ReadOnly
  include Minidoc::Timestamps
  timestamps!
end

DrinkEvents.count(created_at: { "$gt": 4.days.ago }) #=> 0
DrinkEvents.create #=> NoMethodError
