Didn't get Delete User records based on ID - go

Question

I'm using Go with Gorm many2many association from User and Role tables.
type User struct {
//gorm.Model
ID int64 `json:"id" gorm:"primary_key"`
Active sql.NullString ` json:"active " `
Email string `json:"email"`
FullName string `json:"full_name"`
Password string `json:"password"`
Username string `json:"username"`
Groups string `json:"groups"`
Otp string `json:"otp"`
CreatedTimeStamp time.Time `json:"created_time_stamp"`
UpdateTimeStamp time.Time `json:"update_time_stamp"`
LastLogin time.Time `json:"last_login"`
UserCount uint `json:"user_count" `
Roles []Role `gorm:"many2many:user_roles;"`
}
type Role struct {
//gorm.Model
ID int64 `json:"id" gorm:"primary_key"`
Name string `json:"name"`
Users []User `gorm:"many2many:user_roles"`
}
using below code for delete user records and roles based on user id.
var roles []Role
db.Model(Role{}).Where("Name = ?", "ROLE_ADMIN").Take(&roles)
newUser := &User{
Email: user.Email,
FullName: user.FullName,
Username: user.Username,
Groups: groupCreation(user.Username),
Password: EncodePassword(user.Password),
CreatedTimeStamp: time.Now(),
UpdateTimeStamp: time.Now(),
LastLogin: time.Now(),
Roles: roles
}
db.Save(newUser)
**db.Model(&user).Association("Role").Delete(&newUser)**
Once executed last statement but didn't get delete(no impact) records from tables users and user_roles.
Kindly suggest me what is issue.

Answer 1

This code:
db.Model(&user).Association("Role").Delete(&newUser)
by the Gorm documentation:
Remove the relationship between source & arguments if exists, only delete the reference, won’t delete those objects from DB.
You need to use the Delete with Select https://gorm.io/docs/associations.html#Delete-with-Select
So actually it should be:
db.Select("Role").Delete(&newUser)
