嗨,
我正在使用CDS OData v4服务的新OData v2适配器代理(@ sap/cds-odata-v2-adapter-proxy),但是托管关联存在问题:
db \ data-model.cds:
命名空间待办事项; 实体任务{ 密钥ID:整数; title:字符串; 完成:布尔值; plannedTasks:与plannedTasks.task = $ self上的许多PlannedTasks的关联; } 实体人物{ 密钥ID:整数; 名称:字符串; plannedTasks:与plannedTasks.person = $ self上的许多PlannedTasks关联。 } 实体PlannedTasks { 关键任务:任务关联; 关键人物:人民协会; 键startDate:DateTime; key endDate:DateTime; 暂定:布尔值; }
获取/v2/todo/People?$ expand = plannedTasks
{ " d":{ "结果":[{ " ID":1 " name":" Joe", " plannedTasks":{ "结果":[{ " startDate":"/img/Date(1566518400000)/", " endDate":"/img/Date(1566518400000)/", "暂定":是的, " task_ID":1 " person_ID":1 " __metadata":{ " uri":" http://localhost:4004/v2/todo/PlannedTasks(task = undefined,person = undefined,startDate = datetimeoffset'2019-08-23T00:00:00Z',endDate = datetimeoffset'2019-08- 23T00:00:00Z',task_ID = 1,person_ID = 1)", " type":" TodoService.PlannedTasks", " etag":" W/\" QMV7j0dk99JE5TC7oLbhyym0Kkqvdle9NMPCOMMVHWE = \"" }, "任务":{ " __deferred":{ " uri":" http://localhost:4004/v2/todo/PlannedTasks(任务=未定义,人=未定义,startDate = datetimeoffset'%2FDate(1566518400000)%2F',endDate = datetimeoffset'%2FDate(1566518400000)% 2F',task_ID = 1,person_ID = 1)/task" } }, "人":{ " __deferred":{ " uri":" http://localhost:4004/v2/todo/PlannedTasks(task = [object%20Object],person = undefined,startDate = datetimeoffset'%2FDate(1566518400000)%2F',endDate = datetimeoffset'%2FDate (1566518400000)%2F',task_ID = 1,person_ID = 1)/人" } } }] }, " __metadata":{ " uri":" http://localhost:4004/v2/todo/People(1)", " type":" TodoService.People", " etag":" W/\" QMV7j0dk99JE5TC7oLbhyym0Kkqvdle9NMPCOMMVHWE = \"" } }, { " ID":2 " name":" Jane", " plannedTasks":{ "结果":[] }, " __metadata":{ " uri":" http://localhost:4004/v2/todo/People(2)", " type":" TodoService.People", " etag":" W/\" QMV7j0dk99JE5TC7oLbhyym0Kkqvdle9NMPCOMMVHWE = \"" } }, { " ID":3, " name":" Bob", " plannedTasks":{ "结果":[{ " startDate":"/img/Date(1566604800000)/", " endDate":"/img/Date(1566604800000)/", "暂定":假, " task_ID":2 " person_ID":3, " __metadata":{ " uri":" http://localhost:4004/v2/todo/PlannedTasks(task = undefined,person = undefined,startDate = datetimeoffset'2019-08-24T00:00:00Z',endDate = datetimeoffset'2019-08- 24T00:00:00Z',task_ID = 2,person_ID = 3)", " type":" TodoService.PlannedTasks", " etag":" W/\" QMV7j0dk99JE5TC7oLbhyym0Kkqvdle9NMPCOMMVHWE = \"" }, "任务":{ " __deferred":{ " uri":" http://localhost:4004/v2/todo/PlannedTasks(任务=未定义,人=未定义,startDate = datetimeoffset'%2FDate(1566604800000)%2F',endDate = datetimeoffset'%2FDate(1566604800000)% 2F',task_ID = 2,person_ID = 3)/任务" } }, "人":{ " __deferred":{ " uri":" http://localhost:4004/v2/todo/PlannedTasks(task = [object%20Object],person = undefined,startDate = datetimeoffset'%2FDate(1566604800000)%2F',endDate = datetimeoffset'%2FDate (1566604800000)%2F',task_ID = 2,person_ID = 3)/person" } } }] }, " __metadata":{ " uri":" http://localhost:4004/v2/todo/People(3)", " type":" TodoService.People", " etag":" W/\" QMV7j0dk99JE5TC7oLbhyym0Kkqvdle9NMPCOMMVHWE = \"" } } ] } }
实体密钥错误,因此我无法更新PlannedTasks实体:
http://localhost:4004/v2/todo/PlannedTasks(任务=未定义,人=未定义,startDate = datetimeoffset'2019-08-23T00:00:00Z',endDate = datetimeoffset'2019-08-23T00: 00:00Z',task_ID = 1,person_ID = 1)
使用OData v2和CDS Java的类似服务没有任何问题。
这是源代码: https://github.com/pdominique/cap-todo
干杯
