관리자 추가하기 : Fiber v2.x

이 튜토리얼의 소스는 https://github.com/gauryan/fiber-tutorial 에서도 확인할 수 있습니다.

관리자 목록을 보았으니, 이제는 새로운 관리자를 추가해봅시다. 

 

1. 저장 프로시저 (insertAdmin) 생성

DELIMITER $$
CREATE PROCEDURE insertAdmin
  (userid VARCHAR(255),
   password VARCHAR(255),
   nick VARCHAR(255))
BEGIN
  INSERT INTO admins(userid, password, nick) VALUES(userid, password, nick);
END $$
DELIMITER ;

2. 관리자 입력 양식을 만들자. ~/project/xyz/views/mgmt/admin/insert_form.html

<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 추가</h4>
</div>
<div class="modal-body">
  <form name="insert_form" action="/mgmt/admin/insert" method="post">
    <div class="form-group">
      <label>아이디 <small>(필수)</small></label>
      <input type="text" name="userid" class="form-control" required>
    </div>
    <div class="form-group">
      <label>비밀번호 <small>(필수)</small></label>
      <input type="password" id="password" name="passwd1" class="form-control" required>
    </div>
    <div class="form-group">
      <label>비밀번호 확인 <small>(필수)</small></label>
      <input type="password" name="passwd2" class="form-control" required>
    </div>
    <div class="form-group">
      <label>별명 <small>(필수)</small></label>
      <input type="text" name="nick" class="form-control" required>
    </div>
    <div class="form-group" style="text-align: right">
      <input class="btn btn-primary" type="submit" value="관리자 추가" />
    </div>
  </form>
</div>

 

3. ~/project/xyz/controllers/mgmt/admin.go 에 다음 코드를 추가한다.

...
 
// 관리자 추가 폼
func InsertForm(c *fiber.Ctx) error {
    return c.Render("mgmt/admin/insert_form")
}
 
...

 

4. ~/project/xyz/routes/web.go 에서 mgmt 그룹안에 다음을 추가한다.

    mgmtApp.Get("/admin/insert_form", mgmt.InsertForm)

 

5. 관리자 추가 버튼을 클릭하면 모달 다이얼로그 박스 형식의 입력 양식이 나올 것이다.

 

6. 이제, 실제로 DB에 관리자를 추가해보자. ~/project/xyz/controllers/mgmt/admin.go 에 다음을 추가한다.

...
 
// 관리자 추가
func Insert (c *fiber.Ctx) error {
    userid  := c.FormValue("userid")
    passwd1 := c.FormValue("passwd1")
    passwd2 := c.FormValue("passwd2")
    nick    := c.FormValue("nick")
 
    if passwd1 != passwd2 {
        return c.Redirect("/mgmt/admin")
    }
    db := database.DBConn
    db.Exec("CALL insertAdmin(?, ?, ?)", userid, passwd1, nick)
 
    return c.Redirect("/mgmt/admin")
}
 
...

 

7. ~/project/xyz/routes/web.go 에서 mgmt 그룹안에 다음을 추가한다.

    mgmtApp.Post("/admin/insert", mgmt.Insert)

 

8. 코드 작성은 완료되었으니, 실제 화면에서 관리자를 등록해보면 목록에 표시되는 것을 볼 수 있을 것이다.
