# 1.ManyToOne不需要填写依赖和允许跨App安装

  1. 如果是模型的ManyToOne依赖,app.json不需要填写应用依赖
  2. 如果2个APP不存在继承扩展,只存在调用关系或者模型的many2one引用,可以不安装在一起
  3. 注意:如果模型之前存在继承扩展关系,必须安装在一起

1.@ManyToOne 指定targetModel的格式为 appName.modelName 

@Model
public class TestLog extends BaseModel {
   
    @ManyToOne(targetModel = "newSdkApp.TestOrg")// Many2one跨app安装,格式为:其他app的名字.模型名
    @JoinColumn(name = "org_code")
    private Map<String, Object> testOrg;

}

2.如果需要再ManyToOne方添加tab页显示另外一个app的数据,需要再tabs的body里面指定 "app": "newSdkAppOthers"

"tabs": [
	{
		"body": {
			"columns": [
				{
					"label": "备注",
					"name": "remark"
				},
				{
					"label": "创建时间",
					"name": "createDate"
				}
			],
			"app": "newSdkAppOthers",
			"field": "testLogs",
			"type": "grid"
		},
		"header": "日志列表",
		"tbar": []
	}
]
