Functions

func Filling

func Filling(data interface{}, model interface{}) error

Filling filling a model from submitted data data 提交过来的数据结构体 model 定义表模型的数据结构体 相当于是在合并两个结构体(data 必须是 model 的子集)

func FuncName

func FuncName(f interface{}) string

FuncName get func name

func Go

func Go(f func() error) chan error

Go is a basic promise implementation: it wraps calls a function in a goroutine and returns a channel which will later return the function's return value. from beego/bee

func PkgName

func PkgName() string

PkgName get current package name
