MetaModel

MetaModel is an iOS framework designed to help developer to deal with data persistent, JSON parsing and 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)

Usage

Use a meta file in ./meta folder to define your model:

define :User do
  # define User model like this
  attr :nickname, :string
  attr :avatar, :string?
  attr :email, :string, :unique, default: "default@gmail.com"
end

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

Installation

sudo gem install metamodel --verbose

System Requirements: Current version of MetaModel requires macOS with Ruby 2.2.2 or above

Quick Start

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

Initialing MetaModel project

Creating `meta` folder for MetaModel

Generate your model meta file with meta generate.

$ meta generate User

Generating model meta file

-> Adding `user.rb` to meta folder

[!] `user.rb` has already generated, use the command below to edit it.

$ meta build

Building MetaModel.framework in project
  Existing project `./metamodel/MetaModel.xcodeproj`

Analyzing meta files
  -> Resolving `user.rb`

Generating model files
  -> Using User.swift file

Generating MetaModel.framework
  -> MetaModel.framework located in current folder

[!] Please drag MetaModel.framework into Embedded Binaries phrase.

This command build a MetaModel.framework in project root folder, you need to add this framework to Embedded Binaries phrase which located in General tab.
