MetaModel

MetaModel is an iOS framework designed to help developer to deal with data persistent, JSON parsing and offer a bunch of APIs which provides an approach of handling client side database very easily.

MetaModel is under-development, API may constantly change before gets to 1.0.0.

• Dealing with database without writing SQL
• Most concise API to retrieve data from persistent level
• Fastest JSON to model API

MetaModel provides convenience chainable APIs to manipulate models like ActiveRecord.

let json = ["id": 1, "name": "Buzz", "email": "i@metamodel.info"]
let person = Person.parse(json)

// INSERT INTO "people" (id, name, email) VALUES (1, "Buzz", "i@metamodel.info")
person.save

// SELECT "people".* FROM "people" WHERE "people"."id" = 1 LIMIT 1
if var person = Person.find(1) {
    // UPDATE "people" SET "people"."name") = "Buzz" WHERE "people"."id" = 1
    person.update(name: "Draven")
}

// SELECT "people".* FROM "people"
print(Person.all)

Use Metafile in project folder to define your model:

metamodel_version '0.1.0'

define :Article do
  attr :title
  attr :content

  has_many :comments
end

define :Comment do
  attr :content

  belongs_to :article
end

And then run meta build will automatically generate all the code you need.

sudo gem install metamodel --verbose

After installation , run meta init in your iOS project root folder which will make a meta directory in current folder.

$ cd /path/to/project
$ meta init
