Play Framework 1.2.x中的ManyToMany测试治具(Yaml) [英] ManyToMany Test Fixtures (Yaml) in Play Framework 1.2.x

问题描述

我正在使用Play！ 1.2.4 + Morhpia/MongoDB.

I'm using Play! 1.2.4 + Morhpia / MongoDB.

我的模特是沙龙和造型师，他们之间存在许多关系.但是，我无法正确定义测试数据来表示这种关系.

My models are Salons and Stylists which share a many to many relationship. I am however unable to define the test data correctly to represent this relationship.

这就是我所做的

Salon(salon1):
  name: salon1
  city: singapore
  country: singapore

Stylist(stylist1):
  firstName: stylist1
  lastName: stylist1
  title: Stylist 1
  price: $100
  salons: [salon1]

使用此数据，设计师包含沙龙的参考，反之亦然.

With this data, the stylist contains the reference to the salon but not vice-versa.

如何实现双向引用?

谢谢， 斯里

这是模型类..

@Entity("salons")
public class Salon extends Model {
  // ...
  @Reference
  @ManyToMany
  public List<Stylist> stylists;
  // ...
}

@Entity("stylists")
public class Stylist extends Model {
  // ..
  @Reference
  @ManyToMany
  public List<Salon> salons;
  // ..
}

推荐答案

两种方式引用是什么意思?

What do you mean by two way referencing?

如果您想通过代码从Salon实体访问Stylists，那么您将需要具有以下内容:

If you mean you want to be able to access Stylists from your Salon entity in code, then you will need to have something like this:

public class Salon extends Model {

    @ManyToMany
    @JoinTable(name = "salon_stylist", ...)
    public List<Stylist> stylists;

    ...
}

您的造型师实体看起来像这样:

And your Stylist entity can look like this:

public class Stylist extends Model {

    @ManyToMany
    @JoinTable(name = "salon_stylist", ...)
    public List<Salon> salons;

    ...
}        

然后您的yml如下所示:

Then your yml can look like this:

Salon(salon1):
  name: salon1
  city: singapore
  country: singapore

Salon(salon2):
  name: salon2
  city: tokyo
  country: japan

Stylist(stylist1):
  firstName: stylist1
  lastName: stylist1
  title: Stylist 1
  price: $100
  salons: 
    - salon1
    - salon2

只需说stylist1属于salon1和salon2在yml中就足够了(即您不必在两个沙龙yml条目中声明相同).

Just saying that stylist1 belongs to salon1 and salon2 should be enough in the yml (i.e. you shouldn't have to declare the same in the two salon yml entries).
