change of model but database not changed accordingly - go

Question

I'm new to golang.
Here's my code:
//main.go
type Project struct {
gorm.Model
Name string
}
type Log struct {
gorm.Model
Project Project
User User
CheckPoint string
Status uint
}
type User struct {
gorm.Model
Name string
Password string
}
//...
db.AutoMigrate(&Project{}, &Log{}, &User{})
I want to:
Log.Project ==> Project.ID
Log.User ==> User.ID
But in the database logs table, it's:
desc logs;
+-------------+------------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-------------+------------------+------+-----+---------+----------------+
| id | int(10) unsigned | NO | PRI | NULL | auto_increment |
| created_at | datetime | YES | | NULL | |
| updated_at | datetime | YES | | NULL | |
| deleted_at | datetime | YES | MUL | NULL | |
| check_point | varchar(255) | YES | | NULL | |
| status | int(10) unsigned | YES | | NULL | |
+-------------+------------------+------+-----+---------+----------------+
I can't see the ProjectID nor the UserID.
Any guidance?
Thank you in advance.

Hi there,
Maybe I need to explain myself firstly.
I need three tables: projects, users, logs.
In the logs, it records which user did what to which project.
I changed a little:
type Project struct {
gorm.Model
Name string
}
type User struct {
gorm.Model
Name string
Password string
}
type Log struct {
gorm.Model
ProjectID uint
UserID uint
CheckPoint string // ie: what to record
Status uint // ie: record's status
}
...
db.Debug().Model(&Log{}).AddForeignKey("user_id", "users(id)", "RESTRICT", "RESTRICT")
db.Debug().Model(&Log{}).AddForeignKey("project_id", "projects(id)", "RESTRICT", "RESTRICT")
When I ran the code,
Error 1452: Cannot add or update a child row: a foreign key constraint fails (`test`.`logs`, CONSTRAINT `logs_project_id_projects_id_foreign` FOREIGN KEY (`project_id`) REFERENCES `projects` (`id`))
Error 1452: Cannot add or update a child row: a foreign key constraint fails (`test`.`#sql-1a0f3_18`, CONSTRAINT `logs_user_id_users_id_foreign` FOREIGN KEY (`user_id`) REFERENCES `users` (`id`))
I'm lost.

Answer 1

You are using a has one relationship so the foreign key will be in the owned models (Project & User tables should have a log_id) column. Maybe what you want is a belongs to relation.
