如何用gorm填充和嵌入阵列？

Question

I have 2 structs with data like this:

type User struct {
  Pics Pic[]
}

type Pic struct {
  Id int   
  UserId int64
}

Although everytime I insert an User, Each of the pics are inserted on their table everytime I find the users, pics are not populated:

var users []User
db.Limit(pagesize).Where("updated_at > ?", date).Find(&users)

Am I doing something wrong?

I had these issues once. Then I used Join function. See my example that works just fine:

type FileType struct {
     Id         int
}
type File struct {
     Id           int  
     FileType     `xorm:"extends"`
}

file := File{Id: id}


has, err := eng.
    Join("INNER", "FileType", "FileType.IdFileType = File.IdFileType").
    Get(&file)
