How to defination many-to-many relation? readme sample not work.

[Yugo]

I try write all defination in one file，but the migaration only run once. like, only migration user table.

If definition by another file, the abstract class name start with _，is private variable。this is unavailable。 If i use genated model name，the build_runner aserted the variable type is dynamic。

Maybe need more detailed documentation。

like how to definition rbac model.

user.dart

@serializable
@orm
abstract class _User extends Model {
  String get username;

  String get password;

  String get email;

  DateTime get joinDate;

  List<UserRole> get userRoles;

  List<Role> get roles => userRoles.map((m) => m.role).toList();
  
  List<Permission> get permissions => roles.fold([],(acc, role){
    acc.addAll(role.permissions);
    return acc;
  });


  bool can(String resource, String type, [bool check(Permission p)]) {
    var permission = permissions.firstWhere((p){
      return p.resource.contains(resource) && type.contains(type);
    });
    if (check == null) {
      return permission != null ? true : false;
    }
    return check(permission);
  }
}

user_role.dart

@serializable
@orm
abstract class _UserRole extends Model {

  @belongsTo
  User get user;

  @belongsTo
  Role get role;
}

role.dart

@serializable
@orm
abstract class _Role extends Model {
  String get name;

  List<UserRole> get userRoles;

  List<User> get users => userRoles.map((ur) => ur.user).toList();

  List<RolePermission> get rolePermissiong;

  List<Permission> get permissions => rolePermissiong.map((m) => m.permission).toList();
}

permission.dart

@serializable
@orm
abstract class _Permission extends Model {
  String get resource;
  String get type;

  DateTime get end;
  
  List<RolePermission> get rolePermissiong;

  List<Role> get roles => rolePermissiong.map((m) => m.role).toList();
}

role_permission.dart

@serializable
@orm
abstract class _RolePermission extends Model {

  @belongsTo
  Role get role;

  @belongsTo
  Permission get permission;
}

whatever i use serializable or @Serializable(autoIdAndDateFields: false) the user_role and role_permission will not be generator migration.

1. Please bear with me for a little bit - the ORM is still in development (as marked by -dev suffix in the version). Join the Angel chat for continuous updates: https://gitter.im/angel_dart/discussion
2. As of the latest version of angel_migration_runner, having multiple models in one file should be supported. I might need to investigate this more, but run pub upgrade angel_migration_runner first.
3. As of recent updates to angel_serialize_generator, @Serializable(autoIdAndDateFields: false) is no longer necessary.

ok。thx，i will continuous follow-up.
