[Video] Chương quản lý bán hàng - Chức năng đăng ký + đăng nhập hệ thống - Phần 2
- Login & Register:
-> Login Screen -> Login thanh -> GUI Main (ProductFrame)
-> Chua co tai khoan -> Register Screen -> DKy thanh cong -> Login Screen.
Một số lưu trong phát triển ứng quản trị:
- Login thành công -> active -> do admin active.
- Đky tài khoản -> inactive -> đợi admin approve -> active
===========================================================================================
role
- id: primary key
- name: Tên -> hiển thị dữ liệu
user
- username
- email
- password -> md5(md5(pwd) + PRIMARY_KEY)
- role_id: foreign key -> role (id)
- active: tiny -> 0: inactive, 1: active
- Login Screen: email + pwd + active (1)
- Register Screen: Form ĐKy -> add thông tin người vào database -> inactive (active = 0)
- User Screen: Admin login vào đc -> hiển thị danh sách người dùng -> active/inactive
- Home Screen: Fake man hinh -> tu lam sau.
===========================================================================================
B1. Xây dựng database
create table role (
id int primary key auto_increment,
name varchar(50)
);
alter table users
add role_id int references role (id);
alter table users
add active int default 0;
B2. Mapping table vào class object
B3. Confirm database + DAO (Modify - thêm/sửa/xoá/lấy danh sach/tìm kiếm)
