嗨，假設我有 3 個採用以下格式的結構
type Employee struct {
Id int
Name string
CompanyId int `gorm:"column:companyId"`
Company Company `gorm:"foreignKey:CompanyId"`
}
type Company struct {
Id int
CompanyName string
OwnerId `gorm:"column:owner"`
Owner Owner `gorm:"foreignKey:OwnerId"`
}
type Owner struct {
Id int
Name string
Age int
Email string
}
func (E Employee) GetAllEmployees() ([]Employee, error) {
Employees := []Employee
db.Preload("Company").Find(&Employees)
}
// -- -- There response will be like
[
{
id: 1
name: "codernadir"
company: {
id: 5
company_name: "Company"
owner: {
id 0
Name ""
Age 0
Email ""
}
}
}
]
這裡我得到了具有預設值的擁有者值。 給出的範例用於描述我想要達到的目標。
我需要一種方法，如何在載入員工時載入所有者結構及其值？
如有任何建議，我們將不勝感激，提前致謝
您可以使用
gorm:"embedded"標籤：type Employee struct { Id int Name string CompanyId int `gorm:"column:companyId"` Company Company `gorm:"embedded"` } type Company struct { Id int CompanyName string OwnerId `gorm:"column:owner"` Owner Owner `gorm:"embedded"` } type Owner struct { Id int Name string Age int Email string }這是我發現的從嵌入式結構載入嵌套物件的解決方案
db.Preload("Company").Preload("Company.Owner").Find(&Employees)
