本文介绍了为struct字段找到了无效字段,需要为关系定义外键,或者需要实现Valuer/Scanner接口的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
忽略不起作用.
检索错误:
发现无效的结构用于传递结构食品/模型餐厅的字段DeliveryZone,需要为关系定义外键,否则需要实施Valuer/Scanner界面
invalid field found for struct deliveryFood/models.Restaurant's field DeliveryZone, need to define a foreign key for relations or it need to implement the Valuer/Scanner interface
type Restaurant struct {
ID uint
Name string `json:"name"`
EmployeeId uint `json:"employee_id"`
Phone string `json:"phone"`
Address string `json:"address"`
ImagesUrl *string `json:"images_url"`
Position string `json:"position"`
WorkDays string `json:"work_days"`
StartWorkTime string `json:"start_work_time"`
EndWorkTime string `json:"end_work_time"`
Blocked bool `json:"blocked"`
DeliveryZone []*DeliveryZone `json:",omitempty"`
}
type DeliveryZone struct {
ID uint `json:"id"`
RestaurantId uint `json:"restaurant_id"`
Zone string `json:"zone"`
Price float32 `sql:"-"`
}
err := GetDB().Omit(clause.Associations).Model(Restaurant{}).Create(map[string]interface{} {
"name": rest.Name,
"EmployeeId": rest.EmployeeId,
"Phone": rest.Phone,
"Address": rest.Address,
"ImagesUrl": rest.ImagesUrl,
"WorkDays": rest.WorkDays,
"StartWorkTime": rest.StartWorkTime,
"EndWorkTime": rest.EndWorkTime,
"Blocked": rest.Blocked,
"Position": clause.Expr{
SQL: "ST_GeomFromText(?)",
Vars: []interface{}{fmt.Sprintf("POINT((%s))", rest.Position)},
},
}).Error
推荐答案
尝试
DeliveryZone []*DeliveryZone `gorm:"-"`
https://gorm.io/docs/models.html ->ctrl + F->忽略此字段
https://gorm.io/docs/models.html -> ctrl+F -> ignore this field
