type MainController struct {
beego.Controller
}
func (this *MainController) Post() {
var datapoint User
req := this.Ctx.Input.RequestBody
json.Unmarshal([]byte(req), &datapoint)
this.Ctx.WriteString("hello world")
// result := this.Input()
fmt.Println("input value is", datapoint.UserId)
}
this is normal beego router which executes on url occurrence. I want something like
type MainController struct {
beego.Controller
}
func (this *MainController,db *sql.DB) Post() {
fmt.Println("input value is", datapoint.UserId)
}
in order to use database connection pointer. is this possible to achieve this using go...if not please suggest
You can't do this in golang
type MainController struct {
beego.Controller }
func (this *MainController,db *sql.DB) Post() {
fmt.Println("input value is", datapoint.UserId)
}
the declaration in the form
function (c *MainController)Post()
means that Post is a method for the MainController struct you can pass variable into it.
My suggestion is you declare the db pointer as a global variable in your package like below then you will be able to use it inside the Post function
type MainController struct {
beego.Controller
}
var db *sql.DB
func (this *MainController) Post() {
//you can now use the variable db inside here
fmt.Println("input value is", datapoint.UserId)
}
but considering this is Beego which uses the MVC pattern you can do all this from within the model. I suggest you take a look at their awesome documentation here
