:
{
"Id":1,
"CreatedAt":"2018-12-20T10:36:47+08:00",
"User":{
"Id":1,
"Name":"test",
"Order":null
}
} gets user data, however, the value that gets Order is null . If you want to get all the orders obtained by a user, do you want to process them through business logic?
{
"Id":1,
"Name":"test",
"Order":null
}the initial contact with beego, documents made me look confused! Ask for advice!
