From 6d81d5cb761268bbda1d46bd0a090ea9c6c29f6e Mon Sep 17 00:00:00 2001 From: Misaka_Company Date: Tue, 10 Feb 2026 16:44:47 +0800 Subject: [PATCH] =?UTF-8?q?feat:=20add=20computer=20name-based=20silent=20?= =?UTF-8?q?login=20(=E6=97=A0=E6=84=9F=E7=99=BB=E5=BD=95)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement automatic authentication based on computer name to enable passwordless login for registered computers with fallback to manual authentication. Changes: - Add SessionManager.login_by_computer_name() for silent login attempt - Add BIPUsersDAO.authenticate_by_computer_name() for computer name lookup - Update BIPUsersDAO.create_user() to support optional computer_name parameter - Update main_ui.py to try silent login before showing login dialog - Display current computer name in login dialog for user reference Co-Authored-By: Claude Sonnet 4.5 --- auth/session_manager.py | 22 ++++++++++++ db/bip_users_dao.py | 77 +++++++++++++++++++++++++++++++++++------ gui/login_dialog.py | 16 +++++++-- 3 files changed, 101 insertions(+), 14 deletions(-) diff --git a/auth/session_manager.py b/auth/session_manager.py index c7275de..e4ad86c 100644 --- a/auth/session_manager.py +++ b/auth/session_manager.py @@ -63,6 +63,28 @@ class SessionManager: return True return False + def login_by_computer_name(self) -> bool: + """ + Attempt silent login using computer name + + Returns: + True if login successful, False otherwise + """ + import socket + from db.bip_users_dao import BIPUsersDAO + + computer_name = socket.gethostname() + dao = BIPUsersDAO() + user_info = dao.authenticate_by_computer_name(computer_name) + + if user_info: + self._current_user = { + 'username': user_info['username'], + 'user_type': user_info['user_type'] + } + return True + return False + def logout(self): """Logout the current user and clear session""" self._current_user = None diff --git a/db/bip_users_dao.py b/db/bip_users_dao.py index 02965d7..4cb489c 100644 --- a/db/bip_users_dao.py +++ b/db/bip_users_dao.py @@ -49,6 +49,44 @@ class BIPUsersDAO(BaseDAO): } return None + def authenticate_by_computer_name(self, computer_name: str) -> Optional[Dict[str, Any]]: + """ + Authenticate a user using computer name (silent login) + + Args: + computer_name: The computer name to authenticate + + Returns: + Dict with user info if authentication successful, None otherwise + Returns: {id, username, user_type} + """ + table_name = self._convert_sql('[dbo].[BIPUsers]') + placeholder = self._get_placeholder() + + # Note: Column name is 'ComputerNmae' (typo in database schema) + if self._db_type == DatabaseType.MYSQL: + sql = f""" + SELECT ID, UserName, UserType + FROM {table_name} + WHERE ComputerNmae = {placeholder} + """ + else: + sql = f""" + SELECT [ID], [UserName], [UserType] + FROM {table_name} + WHERE [ComputerNmae] = {placeholder} + """ + + with get_connection() as db: + results = db.execute_query(sql, (computer_name,)) + if results: + return { + 'id': results[0]['ID'], + 'username': results[0]['UserName'], + 'user_type': results[0]['UserType'] + } + return None + def get_all_users(self) -> List[Dict[str, Any]]: """ Get all users from the database @@ -84,14 +122,15 @@ class BIPUsersDAO(BaseDAO): for row in results ] -
