GORM Playground Link

Description

There are two struct User and Profile. Before I add UserID field in User, the test is passed. After I add UserID field, the test failed. And the select sql look like

SELECT * FROM `users` WHERE `users`.`user_id` = 1
SELECT * FROM `profiles`

Here is the code I wrote.

package test

import (
    "github.com/glebarez/sqlite" // Pure go SQLite driver, checkout https://github.com/glebarez/sqlite for details
    "github.com/stretchr/testify/require"
    "github.com/stretchr/testify/suite"
    "gorm.io/gorm"
    //"gorm.io/driver/sqlite" // Sqlite driver based on CGO
    "testing"
)

func TestGormTestSuite(t *testing.T) {
    suite.Run(t, new(GormTestSuite))
}

type GormTestSuite struct {
    suite.Suite
    gormDB *gorm.DB
}

func (suite *GormTestSuite) SetupTest() {
    db, err := gorm.Open(sqlite.Open("gorm.db"), &gorm.Config{})
    require.NoError(suite.T(), err)
    suite.gormDB = db

    err = suite.gormDB.Migrator().DropTable(&User{}, &Profile{})
    require.NoError(suite.T(), err)
    err = suite.gormDB.Migrator().AutoMigrate(&User{}, &Profile{})
    require.NoError(suite.T(), err)
}

func (suite *GormTestSuite) Test_Preload() {
    suite.givenUser(User{ID: 1, Name: "user1"})
    suite.givenProfile(Profile{ID: 1, UserID: 1, Description: "profile1"})

    var p Profile
    err := suite.gormDB.Debug().Preload("User").Find(&p).Error
    require.NoError(suite.T(), err)
    require.Equal(suite.T(), "user1", p.User.Name)
}

func (suite *GormTestSuite) givenProfile(profile Profile) {
    err := suite.gormDB.Create(&profile).Error
    require.NoError(suite.T(), err)
}

func (suite *GormTestSuite) givenUser(user User) {
    err := suite.gormDB.Create(&user).Error
    require.NoError(suite.T(), err)
}

type User struct {
    ID     int
    Name   string
    UserID int
}

type Profile struct {
    ID          int
    UserID      int
    User        User `gorm:"foreignKey:UserID"`
    Description string
}
