[GO] golang練習項目-gorm與mysql的增刪查改操做

下面代碼放在models包下的users.go中

表結構和struct字段是一致的,把表字段的下劃線變成首字母大寫的駝峯命名

建立,查找,刪除,更新用戶,見下面的具體方法

 

package models

import (
    _ "github.com/jinzhu/gorm/dialects/mysql"
)
type User struct {
    Model
    Name string `json:"name"`
    Password string `json:"password"`
    Nickname string `json:"nickname"`
    Avator string `json:"avator"`
    RoleName string `json:"role_name"`
}
func CreateUser(name string,password string,avator string,nickname string){
    user:=&User{
        Name:name,
        Password: password,
        Avator:avator,
        Nickname: nickname,
    }
    DB.Create(user)
}
func UpdateUser(id string,name string,password string,avator string,nickname string){
    user:=&User{
        Name:name,
        Avator:avator,
        Nickname: nickname,
    }
    if password!=""{
        user.Password=password
    }
    DB.Model(&User{}).Where("id = ?",id).Update(user)
}
func FindUser(username string)User{
    var user User
    DB.Where("name = ?", username).First(&user)
    return user
}
func FindUserById(id interface{})User{
    var user User
    DB.Where("id = ?", id).First(&user)
    return user
}
func DeleteUserById(id string){
    DB.Where("id = ?",id).Delete(User{})
}
func FindUsers()[]User{
    var users []User
    DB.Order("id desc").Find(&users)
    return users
}
func FindUserRole(query interface{},id interface{})User{
    var user User
    DB.Select(query).Where("user.id = ?", id).Joins("join user_role on user.id=user_role.user_id").Joins("join role on user_role.role_id=role.id").First(&user)
    return user
}
