Example: Automatch

The automatch examples uses the automatcher to match three models with varying level of depth:

type Account // domain
    // 0
    ID      int
    Name    string
    Email   string
            // 1
    User    domain.DomainUser
                UserID  int
                Name    string    
type User    // models
    // 0 
    UserID    int
    Name      string
              // 1
    UserData  models.UserData
                  Options map[string]interface{}
                  // 2
                  Data    models.Data
                        ID      int
type Account // models
    // 0
    ID       int
    Name     string
    Password string
    Email    string

YML

The YML specifies to use a depth of 1 for the domain Account. This means that the domain Account will have values set as far as a level // 1 depth level in addition to its respective from fields. The YML specifies to use a depth of 0 for the models User (by default). This means that the domain User will only assign values (to the domain Account) if the field is at a depth level of // 0.
