我愿意使用RxSwift在模型值和视图控制器之间进行MVVM绑定.我想按照这个realm.io教程,但从那时起绑定显然已经改变,示例代码不能编译.这是示例代码,我认为我已经修复了最糟糕的拼写错误/丢失的东西:

LoginViewModel.swift

import RxSwift

struct LoginViewModel {

    var username = Variable<String>("")
    var password = Variable<String>("")

    var isValid : Observable<Bool>{
        return Observable.combineLatest(self.username.asObservable(), self.password.asObservable())
        { (username, password) in
            return username.characters.count > 0
                && password.characters.count > 0
        }
    }
} 

LoginViewController.swift

import RxSwift
import RxCocoa
import UIKit

class LoginViewController: UIViewController {
    var usernameTextField: UITextField!
    var passwordTextField: UITextField!
    var confirmButton: UIButton!

    var viewModel = LoginViewModel()

    var disposeBag = DisposeBag()

    override func viewDidLoad() {
        usernameTextField.rx.text.bindTo(viewModel.username).addTo(disposeBag)
        passwordTextField.rx.text.bindTo(viewModel.password).addTo(disposeBag)

        //from the viewModel
        viewModel.rx.isValid.map { $0 } …

我正在将sequelize与sequ​​elize-typescript库一起使用，并试图实现以下关系：

团队.ts

@Scopes({
  withPlayers: {
    include: [{model: () => User}]
  }
})
@Table
export default class Team extends Model<Team> {

  @AllowNull(false)
  @Column
  name: string;

  @BelongsToMany(() => User, () => TeamPlayer)
  players: User[];
}

用户.ts

@Scopes({
  withTeams: {
    include: [{model: () => Team, include: [ () => User ]}]
  }
})
@Table
export default class User extends Model<User> {

  @AllowNull(false)
  @Column
  firstName: string;

  @AllowNull(false)
  @Column
  lastName: string;

  @BelongsToMany(() => Team, () => TeamPlayer)
  teams: Team[];
}

TeamPlayer.ts

@DefaultScope({
  include: …
