Functions

func CloseDB

func CloseDB()

func CreateBeforeHook

func CreateBeforeHook(gormDB *gorm.DB)

InterceptCreatePramsNotPtrError 拦截 create 函数参数如果是非指针类型的错误,新用户最容犯此错误

func DB

func DB() *gorm.DB

func Init

func Init()

func InitDB

func InitDB() *gorm.DB

func MaskNotDataError

func MaskNotDataError(gormDB *gorm.DB)

MaskNotDataError 解决gorm v2 包在查询无数据时，报错问题（record not found），但是官方认为报错是应该是，我们认为查询无数据，代码一切ok，不应该报错

func UpdateBeforeHook

func UpdateBeforeHook(gormDB *gorm.DB)

UpdateBeforeHook InterceptUpdatePramsNotPtrError 拦截 save、update 函数参数如果是非指针类型的错误 对于开发者来说，以结构体形式更新数，只需要在 update 、save 函数的参数前面添加 & 即可 最终就可以完美兼支持、兼容 gorm 的所有回调函数 但是如果是指定字段更新，例如： UpdateColumn 函数则只传递值即可，不需要做校验

func UpdateCreatedTimeHook

func UpdateCreatedTimeHook(db *gorm.DB)

func UpdateDeletedTimeHook

func UpdateDeletedTimeHook(db *gorm.DB)

func UpdateIdHook

func UpdateIdHook(db *gorm.DB)

func UpdateLastModifiedTimeHook

func UpdateLastModifiedTimeHook(db *gorm.DB)
