Types

type RelationType

type RelationType int

const (
	// Every *one* country can have only *one* capital and
	// every one capital can only have one country
	// A 1 <----> 1 B
	OneToOne RelationType = iota
	// Every *one* user has *many* addresses (OneToMany) and
	// each one of those addresses can only have one user (ManyToOne)
	// A 1 <----> n B
	// B n <----> 1 B
	// OneToMany is the inverse of ManyToOne
	// The "One" part specifies which of the two models
	// is only allowed to be owned once by the other one
	OneToMany
	// *Many* addresses can have only *one* user each (ManyToOne) and
	// each of those users can have any number of addresses (OneToMany)
	// A n <----> 1 B
	// B 1 <----> n A
	// ManyToOne is the inverse of OneToMany
	ManyToOne

	// *Many* orders can have *many* products and
	// any product can belong to any order
	ManyToMany
