通过Go获取Google的数据存储区密钥值

Question

I have a struct:

type struct Foo {
    Id ??
    Name string
}

I get a list of Foos doing, where "c" is a NewContext():

    q := datastore.NewQuery("Drug")
    var foos []Foo
    _, err := q.GetAll(c, &foos)

The Id is not populated, but the Name is. I'm trying to figure out how to get the Id to populate

Answer 1

The GetAll function returns a slice of the keys:

keys, err := q.GetAll(c, &foos)

The key for foos[i] is keys[i].

Use a loop to store the id in the entity if that's what you need:

for i := range keys {
   foos[i].ID = keys[i].IntID() // or .StringID()
}
