Jhipster关系的CRUd问题

Question

我正在导入以下jdl以生成一个简单的jhipster整体。

启动后我检查了h2 db，它看起来很完美，但是当我尝试使用ui创建新的InventryModel或Inventory实体时，下拉列表根本无法正常工作。

当我添加{required}（以强制执行非null fks）时，这似乎是它开始走下坡路的地方

  config {
    baseName hipcars
    packageName com.hipcars
    applicationType monolith
    databaseType sql
    devDatabaseType h2Disk
    prodDatabaseType mysql
    cacheProvider ehcache
    enableHibernateCache true
    authenticationType jwt
    clientFramework angularX
    useSass false
    clientPackageManager npm
    enableTranslation false
    languages [ en, zh-cn, es ]
    messageBroker kafka
    searchEngine elasticsearch
    serverPort 8080
    websocket false
    testFrameworks [protractor, cucumber, gatling]
    buildTool gradle
  }
  entities *
}

entity Make {
  name String required unique maxlength(20),
  desc String
}

entity InventoryModel {
  name String required unique maxlength(20),
  vehicleType VehicleType
  desc String
}

enum VehicleType {
  SEDAN,
  COUPE
}

entity Inventory {
    vin String required unique maxlength(17),
  comment   String maxlength(128)
}

relationship ManyToOne {
  InventoryModel{make(name) required} to Make,
  Inventory{inventoryModel(name) required} to InventoryModel
}

dto * with mapstruct

paginate * with pagination
service * with serviceClass
search * with elasticsearch
filter *

但是，如果我这样做：

application {
  config {
    baseName hipcars
    packageName com.hipcars
    applicationType monolith
    databaseType sql
    devDatabaseType h2Disk
    prodDatabaseType mysql
    cacheProvider ehcache
    enableHibernateCache true
    authenticationType jwt
    clientFramework angularX
    useSass false
    clientPackageManager npm
    enableTranslation false
    languages [ en, zh-cn, es ]
    messageBroker kafka
    searchEngine elasticsearch
    serverPort 8080
    websocket false
    testFrameworks [protractor, cucumber, gatling]
    buildTool gradle
  }
  entities *
}

entity Make {
  name String required unique maxlength(20),
  desc String
}

entity InventoryModel {
  name String required unique maxlength(20),
  vehicleType VehicleType
  desc String
}

enum VehicleType {
  SEDAN,
  COUPE
}

entity Inventory {
    vin String required unique maxlength(17),
  comment   String maxlength(128)
}

relationship ManyToOne {
  InventoryModel{make(name)} to Make{required},
  Inventory{inventoryModel(name)} to InventoryModel{required}
}

dto * with mapstruct

paginate * with pagination
service * with serviceClass
search * with elasticsearch
filter *

原始屏幕运行良好，但是对Inventory.inventoryModel或InventoryModel.make没有“不是空”约束，这正是我真正需要的

Answer 1

尝试一下：

relationship ManyToOne {
  InventoryModel{make(name) required} to Make,
  Inventory{inventoryModel(name) required} to InventoryModel
}

代替此：

relationship ManyToOne {
  InventoryModel{make(name)} to Make{required},
  Inventory{inventoryModel(name)} to InventoryModel{required}
}
