pgears_sample_0.go

package main
 import (
     "fmt"
     "github.com/Dwarfartisan/pgears"
"time" )
 var Engine *pgears.Engine
 type Usertbl struct{
     Name string           `field:"name" pk:"true"`
     Signup_date time.Time `field:"signup_date"`
 }
 func main(){
     Engine, _ = pgears.CreateEngine("postgres://dbuser:pass
 word@127.0.0.1/exampledb?sslmode=disable")
     var usertbl Usertbl
     Engine.MapStructTo(&usertbl, "usertbl")
     var usertbl_m Usertbl
     usertbl_m.Name = "test"
     usertbl_m.Signup_date = time.Now()
     err := Engine.Insert(&usertbl_m)
     if err != nil {
         fmt.Println(err)
return }
     fmt.Println("insert ok")
 }

第12行应该return出错误信息。

var err error
Engine, err = pgears.CreateEngine("postgres://dbuser:pass
 word@127.0.0.1/exampledb?sslmode=disable")
if err != nil {
    panic(err)
}

具体在这个例子中，第20行的判断，遇到错误完全可以直接panic

     if err != nil {
         panic(err)
     }
