Email

pub struct Email(String) derive(Eq, @moonbitlang/core/debug.Debug
Debug)

A type of the program's own: stored as text, refused on the way back when it has no @.

Hero

source

pub struct Hero {
  id : Int64?
  name : String
  secret : String
  age : Int?
  power : Double
  team_id : Int64?
  email : Email
  visits : Int
}

A field without annotations is a column named after it, NOT NULL unless its type is T?. #orm.skip keeps a field out of the table and fills it from Default when a row is read. #orm.index adds an index over its columns; index=true on a column adds one over that column alone.

Hero::model

source

fn Hero::model() -> @moonbitstack/moonorm/schema.Model
Model[Hero]

Hero::team

source

fn Hero::team() -> @moonbitstack/moonorm/schema.Relation
Relation[Hero, Team]

Team

source

pub struct Team {
  id : Int64?
  name : String
}

The parent table heroes point at. An autoincrement key is T?: None until the database assigns it, and left out of the INSERT meanwhile. heroes is a relation: Team::heroes(), loaded with Session::load.

Team::heroes

source

fn Team::heroes() -> @moonbitstack/moonorm/schema.Relation
Relation[Team, Hero]

Team::model

source

fn Team::model() -> @moonbitstack/moonorm/schema.Model
Model[Team]
