관리자 수정하기 : Fiber v2.x

 

 

1. ~/project/xyz/views/mgmt/admin/update_form.html 을 작성한다.

<div class="modal-header">
  <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
  <h4 class="modal-title">관리자 수정</h4>
</div>
<div class="modal-body">
  <form name="update_form" action="/mgmt/admin/update" method="post">
    <div class="form-group">
      <label>아이디</label>
      <input type="text" name="userid" class="form-control" readonly required pattern="[a-zA-Z0-9]+" value="{{ .Admin.Userid }}"/>
      <input type="hidden" name="id" class="form-control" value="{{ .Admin.Sno }}" />
    </div>
    <div class="form-group">
      <label>별명 <small>(필수)</small></label>
      <input type="text" name="nick" class="form-control" required value="{{ .Admin.Nick }}"/>
    </div>
    <div class="form-group" style="text-align: right">
      <input class="btn btn-primary" type="submit" value="관리자 수정" />
    </div>
  </form>
</div>

 

2. ~/project/xyz/controllers/mgmt/admin.go 에 다음을 추가한다.

...
 
// 관리자 수정 폼
// /mgnt/admin/update_form/{id}
func UpdateForm (c *fiber.Ctx) error {
    type Admin struct {
        Sno    int
        Userid string
        Passwd string
        Nick   string
    }
    var admin Admin
 
    id := c.Params("id")
 
    db := database.DBConn
    db.Raw("CALL getAdmin(?)", id).First(&admin)
    data := fiber.Map{"Admin": admin}
    return c.Render("mgmt/admin/update_form", data)
}
 
...

 

3. ~/project/xyz/routes/web.go 에 다음을 추가한다.

    mgmtApp.Get("/admin/update_form/:id", mgmt.UpdateForm)

 

4. 이제, 수정 버튼을 클릭하면 수정할 수 있는 폼이 나타나게 될 것이다. 마지막으로 실제로 수정을 처리하는 루틴을 작성하고 라우터에 등록하자. 그전에 updateAdmin 이라는 저장 프로시저부터 만들어야겠지?

5. ~/project/xyz/controllers/mgmt/admin.go 에 다음을 추가한다.

...
 
// 관리자 수정
// /mgmt/admin/update
func Update (c *fiber.Ctx) error {
    id   := c.FormValue("id")
    nick := c.FormValue("nick")
 
    db := database.DBConn
    db.Exec("CALL updateAdmin(?, ?)", id, nick)
 
    return c.Redirect("/mgmt/admin")
}
 
...

 

6. ~/project/xyz/routes/web.go 에 다음을 추가하고, 수정 작업을 진행해보자.

    mgmtApp.Post("/admin/update", mgmt.Update)
