為了實作我的計劃，我使用 PyQt5 撰寫程式，制作了一個簡易 GUI 的 學生管理系統，作為 2021 年最后一個程式，運用到了我在2021年所學的大部分知識，絕對算得上是壓軸程式，但是并沒有給界面做美化，
- 登錄界面
- 主界面
一、登陸界面搭建
登錄界面用的 Designer 可視化程式搭建的，動動滑鼠就能輕松搭建出一個用戶界面，
然后在 Pycharm 中用 PyUIC 把 .ui 檔案轉為 .py 檔案，
二、登陸驗證
在界面程式中給兩個按鈕（登錄 和 退出）系結信號
# 退出
self.retranslateUi(widget)
self.pushButton_2.clicked.connect(widget.close) # type: ignore
# 登錄
self.pushButton.clicked.connect(self.login_in) # type: ignore
self.pushButton.setShortcut('Return')
寫登錄信號槽
# 驗證登錄
def login_in(self):
# 全域變數傳參給其他所有界面
global gl_db
global gl_host
global gl_pwd
global gl_user
global gl_port
gl_db = self.lineEdit_5.text()
gl_host = self.lineEdit_3.text()
gl_pwd = self.lineEdit_2.text()
gl_user = self.lineEdit.text()
try:
port = int(self.lineEdit_4.text())
try:
conn = pymysql.connect(host=gl_host, port=gl_port, db=gl_db, user=gl_user, password=gl_pwd)
print('登錄資料庫{}成功'.format(gl_db))
self.messageDialog('提示', '登錄資料庫{}成功'.format(gl_db))
conn.close()
del conn
# 登錄成功后跳轉到主界面
self.main_show = Fulling()
self.main_show.show()
mainWindow.close()
except pymysql.err.OperationalError:
print('由于目標計算機積極拒絕，無法連接，')
self.messageDialog('警告', '由于目標計算機積極拒絕，無法連接，')
except ValueError:
print('埠號錯誤')
self.messageDialog('警告', '埠號錯誤')
except Exception as err:
print('錯誤：', err)
self.messageDialog('警告', str(err))
# 提示資訊
def messageDialog(self, title, text):
msg_box = QtWidgets.QMessageBox(QtWidgets.QMessageBox.Warning, title, text)
msg_box.exec_()
登錄邏輯程式代碼
class Login(QMainWindow):
def __init__(self):
super().__init__()
self.setFixedSize(600, 400) # 禁止拖動
self.setWindowIcon(QtGui.QIcon('./img/001.ico')) # 設定表單標題圖示
self.setWindowFlags(QtCore.Qt.WindowMinimizeButtonHint) # 禁用最大化
# 背景圖片
image = QtGui.QPixmap()
image.load(r'./img/login_bg.jpg')
bg = QtGui.QPalette()
bg.setBrush(self.backgroundRole(), QtGui.QBrush(image))
self.setPalette(bg)
self.setAutoFillBackground(True)
if __name__ == '__main__':
gl_db = ''
gl_host = ''
gl_pwd = ''
gl_user = ''
gl_port = 0
# 創建 QApplication 類的實體
logapp = QApplication(sys.argv)
# 創建表單
mainWindow = Login()
# 關聯login
ui = Ui_widget()
ui.setupUi(mainWindow)
# 打開表單
mainWindow.show()
# 退出表單
sys.exit(logapp.exec_())
三、主界面
因為主界面涉及到的控制元件比較復雜，所以直接用代碼寫出來，不使用 Designer，
1、初始化
- 先給界面初始化，標題，視窗大小，圖示，控制元件，并且連接資料庫
class Fulling(QWidget):
# 初始化
def __init__(self):
super().__init__()
# 視窗標題
self.setWindowTitle('學生管理系統')
# 視窗大小
self.resize(720, 600)
# 視窗居中
self.center()
# 圖示
self.setWindowIcon(QIcon('./img/001.ico'))
# 連接資料庫
self.conn = pymysql.connect(host=gl_host, port=gl_port, user=gl_user, password=gl_pwd, db=gl_db)
self.tree_view = None
self.table_view = None
self.queryModel = None
self.text_edit = None
self.run_button = None
self.row = None
self.vol = None
self.text_browser = None
self.clear_button = None
self.add_db_view = None
self.del_db_view = None
self.cur = self.conn.cursor()
self.init_ui()
# 視窗居中
def center(self):
screen = QDesktopWidget().screenGeometry()
size = self.geometry()
self.move(round((screen.width() - size.width()) / 2), round((screen.height() - size.height()) / 2))
# 警告資訊
@staticmethod
def message_dialog(title, text):
msg_box = QtWidgets.QMessageBox(QtWidgets.QMessageBox.Warning, title, text)
msg_box.exec_()
2、添加控制元件
- 視窗添加控制元件，并為他們布局
# 視窗布局
def create_window(self):
# 設定樹屬性
self.tree_view = QTreeWidget()
# 設定表格屬性
self.table_view = QTableWidget()
# 設定文本框
self.text_edit = QTextEdit()
# 設定運行按鈕
self.run_button = QPushButton('運行所有代碼')
# 設定清空按鈕
self.clear_button = QPushButton('清空代碼')
# 設定查看文本
self.text_browser = QTextBrowser()
# 表格寬度自適應
self.table_view.horizontalHeader().setStretchLastSection(True)
self.table_view.horizontalHeader().setSectionResizeMode(QHeaderView.Stretch)
# 左側布局
left_layout = QVBoxLayout()
left_layout.addWidget(self.tree_view, 15)
left_layout.addWidget(self.text_browser, 9)
# 右中
mid_layout = QHBoxLayout()
mid_layout.addWidget(self.run_button)
mid_layout.addWidget(self.clear_button)
mid_layout.addWidget(QSplitter())
# 右側布局
right_layout = QVBoxLayout()
right_layout.addWidget(self.table_view, 15)
right_layout.addLayout(mid_layout, 1)
right_layout.addWidget(self.text_edit, 8)
# 創建界面
layout = QHBoxLayout(self)
layout.addLayout(left_layout, 1)
layout.addLayout(right_layout, 3)
self.setLayout(layout)
3、設定函式與信號
- 給每個控制元件添加自己的函式和信號
# 設定視窗主要部件和信號
def init_ui(self):
# 創建視窗
self.create_window()
# 設定樹
self.set_tree_view()
# 設定表格
self.set_table_view()
# 設定文本框
self.set_text_edit()
# 創建運行按鈕
self.set_run_button()
# 創建清空按鈕
self.set_clear_button()
# 創建查看文本
self.set_text_browser()
# 信號槽
self.tree_view.clicked.connect(self.on_tree_clicked)
self.run_button.clicked.connect(self.run_program)
self.clear_button.clicked.connect(self.clear_all)
# 給樹添加右鍵
self.tree_view.setContextMenuPolicy(Qt.CustomContextMenu)
self.tree_view.customContextMenuRequested.connect(self.right_menu_show)
# 運行按鈕快捷鍵
self.run_button.setShortcut('F5')
4、樹的函式
- 讓樹能夠顯示所有的資料表
- 本來想的是把所有的資料表、視圖、事件等都顯示出來，但是這里我只寫了顯示資料表
# 樹
def set_tree_view(self):
# 樹行數
self.tree_view.setColumnCount(1)
# 樹標題
self.tree_view.setHeaderLabel(gl_db + '.db')
# 設定根節點
root = QtWidgets.QTreeWidgetItem(self.tree_view)
root.setText(0, '表') # 只有一列
root.setIcon(0, QIcon('img/db_logo.png'))
# 創建游標
cursor = self.conn.cursor()
cursor.execute("show tables;")
res = cursor.fetchall()
# 遍歷表
for i in range(len(res)):
child = QtWidgets.QTreeWidgetItem(root) # 指定父目錄
child.setText(0, res[i][0])
child.setText(1, '{}'.format(i + 1))
child.setIcon(0, QIcon('img/table_logo.png'))
# 樹默認收縮
root.setExpanded(False)
# 樹根節點
self.tree_view.addTopLevelItem(root)
- 樹中左鍵單擊展開樹 或 打開資料表
# 樹左鍵單擊
def on_tree_clicked(self):
try:
# 獲取樹中的內容
item = self.tree_view.currentItem()
# 如果單擊的是根目錄則展開或收縮樹
if item.text(0) == '表':
print('左鍵單擊{}'.format(item.text(0)))
if self.tree_view.currentItem().isExpanded():
self.tree_view.collapseAll()
else:
self.tree_view.expandAll()
# 如果單擊的是表則打開表
else:
item = self.tree_view.currentItem()
self.cur.execute('select * from ' + item.text(0))
self.select_run()
print('左鍵單擊{}'.format(item.text(0)))
except Exception as e:
print('樹左鍵單擊{}'.format(e))
self.message_dialog('提示', '請先輸入資料')
- 樹中右鍵單擊顯示 右鍵選單選項
# 樹右鍵單擊
def right_menu_show(self):
try:
item = self.tree_view.currentItem()
if item.text(0) == '表':
print('右鍵單擊{}'.format(item.text(0)))
# 添加選單選項
self.contextMenu = QMenu()
self.add_db = self.contextMenu.addAction(u'新建資料表')
self.flash_db = self.contextMenu.addAction(u'重繪')
self.close_db = self.contextMenu.addAction(u'退出')
self.contextMenu.popup(QCursor.pos())
# 給選單選項系結信號
self.add_db.triggered.connect(self.add_database) # type:ignore
self.flash_db.triggered.connect(self.flash) # type:ignore
self.close_db.triggered.connect(self.close_database) # type:ignore
self.contextMenu.show()
else:
# 資料表的右鍵
print('右鍵單擊{},序號是{}'.format(item.text(0), item.text(1)))
self.contextMenu = QMenu()
self.open = self.contextMenu.addAction(u'打開表')
self.drop = self.contextMenu.addAction(u'洗掉表')
self.add = self.contextMenu.addAction(u'添加記錄')
self.delete = self.contextMenu.addAction(u'洗掉記錄')
self.update = self.contextMenu.addAction(u'更改記錄')
self.select = self.contextMenu.addAction(u'查詢記錄')
self.open.triggered.connect(self.open_table) # type:ignore
self.drop.triggered.connect(self.drop_table) # type:ignore
self.add.triggered.connect(self.add_table) # type:ignore
self.delete.triggered.connect(self.delete_table) # type:ignore
self.update.triggered.connect(self.update_table) # type:ignore
self.select.triggered.connect(self.select_table) # type:ignore
self.contextMenu.popup(QCursor.pos())
self.contextMenu.show()
except Exception as e:
print(e)
5、右鍵選項信號槽
- 根目錄的右鍵選單
# 樹重繪
def flash(self):
"""添加資料表后的重繪操作"""
print('重繪')
item = self.tree_view.currentItem()
root = QtWidgets.QTreeWidgetItem(self.tree_view)
root.setText(0, '表') # 只有一列
root.setIcon(0, QIcon('img/db_logo.png'))
cursor = self.conn.cursor()
cursor.execute("show tables;")
res = cursor.fetchall()
# 清除樹
curr_node = self.tree_view.currentItem()
root_index = self.tree_view.indexOfTopLevelItem(curr_node)
self.tree_view.takeTopLevelItem(root_index)
# 再把重繪獲取的樹放上去
for i in range(len(res)):
child = QtWidgets.QTreeWidgetItem(root) # 指定父目錄
child.setText(0, res[i][0])
child.setText(1, '{}'.format(i + 1))
child.setIcon(0, QIcon('img/table_logo.png'))
# 新建資料表 這里要用另外的視窗作為對話框，在第四點
def add_database(self):
try:
# 打開對話框
self.add_db_view = AdDB()
add_ui = Ui_add_db_object()
add_ui.setupUi(self.add_db_view)
self.add_db_view.show()
except Exception as e:
print(e)
print('新建資料表')
# 退出資料表
def close_database(self):
reply = QMessageBox.question(self, '退出', '確定退出', QMessageBox.Yes | QMessageBox.No, QMessageBox.Yes)
if reply == QMessageBox.Yes:
sender = self.sender()
main_app_db = QApplication.instance()
main_app_db.quit()
print('退出資料表')
- 資料表的右鍵選單，下面四個操作沒有寫完，因為需要新建一個對話框
# 右鍵打開
def open_table(self):
item = self.tree_view.currentItem()
self.cur.execute('select * from ' + item.text(0))
self.select_run()
print('打開 {}'.format(item.text(0)))
# 右鍵洗掉表
def drop_table(self):
item = self.tree_view.currentItem()
reply = QMessageBox.question(self, '洗掉表', '確定要洗掉嗎？', QMessageBox.Yes | QMessageBox.No, QMessageBox.Yes)
if reply == QMessageBox.Yes:
self.cur.execute('drop table ' + item.text(0))
self.text_browser.append('洗掉表 {} 成功，右擊根目錄重繪'.format(item.text(0)))
print('洗掉 {}'.format(item.text(0)))
# TODO 添加記錄
def add_table(self):
self.message_dialog('提示', '功能還沒開發')
print('添加記錄')
# TODO 洗掉記錄
def delete_table(self):
try:
self.del_db_view = DelDB()
del_ui = Ui_delete_win()
del_ui.setupUi(self.del_db_view)
self.del_db_view.show()
except Exception as e:
print(e)
print('洗掉記錄')
# TODO 更改記錄
def update_table(self):
self.message_dialog('提示', '功能還沒開發')
print('更改記錄')
# TODO 查詢記錄
def select_table(self):
self.message_dialog('提示', '功能還沒開發')
print('查詢記錄')
6、資料表顯示函式
- 定義表格控制元件是用來顯示資料表的
# 表格控制元件
def set_table_view(self):
self.cur.execute('show tables')
db_len = self.cur.fetchone()
self.cur.execute('select * from ' + db_len[0]) # 將資料從資料庫中拿出來
self.select_run()
- 讓所選表的資料顯示在表格控制元件里
這里的代碼參考的是 PyQt實作讀取MySql資料庫表資料將其顯示在TableWidget并保存為excel表格
# 表格填充內容
def table_data(self, i, j, data):
item = QtWidgets.QTableWidgetItem()
self.table_view.setItem(i, j, item)
item = self.table_view.item(i, j)
item.setText(str(data))
# 運行查詢
def select_run(self):
try:
total = self.cur.fetchall()
col_result = self.cur.description
self.row = self.cur.rowcount # 取得記錄個數，用于設定表格的行數
if self.row == 0:
self.text_browser.moveCursor(QTextCursor.End)
self.text_browser.append('資料表中沒有任何記錄')
else:
self.vol = len(total[0]) # 取得欄位數，用于設定表格的列數
col_result = list(col_result)
a = 0
self.table_view.setColumnCount(self.vol)
self.table_view.setRowCount(self.row)
for i in col_result: # 設定表頭資訊，將mysql資料表中的表頭資訊拿出來，放進TableWidget中
item = QtWidgets.QTableWidgetItem()
self.table_view.setHorizontalHeaderItem(a, item)
item = self.table_view.horizontalHeaderItem(a)
item.setText(i[0])
a = a + 1
total = list(total) # 將資料格式改為串列形式，其是將資料庫中取出的資料整體改為串列形式
for i in range(len(total)): # 將相關的資料
total[i] = list(total[i]) # 將獲取的資料轉為串列形式
for i in range(self.row):
for j in range(self.vol):
self.table_data(i, j, total[i][j])
except Exception as e:
print(e)
7、運行代碼按鈕信號槽
- 運行代碼按鈕需要識別文本框內輸入的操作是增、刪、改、查、創建資料表中的哪一個
# 運行按鈕
def run_program(self):
try:
# 獲取填寫的代碼
text = self.text_edit.toPlainText()
# 刪掉所有的換行
text = text.replace('\n', '')
# 所有代碼大寫
text = text.upper()
# 不同代碼分片
texts = text.split(';')
for i in range(len(texts)):
try:
if texts[i][:6] == 'SELECT':
print('執行查詢{}'.format(texts[i]))
self.cur.execute(texts[i]) # 將資料從資料庫中拿出來
self.select_run()
self.text_browser.moveCursor(QTextCursor.End)
self.text_browser.append('查詢{}'.format(texts[i]))
self.row_ref()
elif texts[i][:6] == 'UPDATE':
print('執行更新{}'.format(texts[i]))
self.cur.execute(texts[i]) # 將資料從資料庫中拿出來
self.text_browser.moveCursor(QTextCursor.End)
self.text_browser.append('更新{}'.format(texts[i]))
self.row_ref()
elif texts[i][:6] == 'INSERT':
print('執行插入{}'.format(texts[i]))
self.cur.execute(texts[i]) # 將資料從資料庫中拿出來
self.text_browser.moveCursor(QTextCursor.End)
self.text_browser.append('插入{}'.format(texts[i]))
self.row_ref()
elif texts[i][:6] == 'DELETE':
print('執行洗掉{}'.format(texts[i]))
self.cur.execute(texts[i]) # 將資料從資料庫中拿出來
self.text_browser.moveCursor(QTextCursor.End)
self.text_browser.append('洗掉{}'.format(texts[i]))
self.row_ref()
elif texts[i][:6] == 'CREATE' and texts[i].find('TABLE') != -1:
print('創建資料表')
self.cur.execute(texts[i]) # 將資料從資料庫中拿出來
self.text_browser.moveCursor(QTextCursor.End)
self.text_browser.append('創建資料表{}'.format(texts[i]))
self.flash()
except Exception as e:
if '1096' in str(e):
print('沒有使用資料庫')
self.message_dialog('沒有使用資料庫', str(e))
elif '1054' in str(e):
print('沒有這個資料庫')
self.message_dialog('沒有這個資料庫', str(e))
elif '1064' in str(e):
print('語法錯誤')
self.message_dialog('語法錯誤', str(e))
else:
print('rr', e)
self.message_dialog('其他錯誤', str(e))
print('run', text)
except Exception as e:
print('e:', e)
- 執行 SQL 陳述句之后，查看影響行，把結果列印在富文本瀏覽器中
# 查看受影響行
def row_ref(self):
cur_count = self.cur.rowcount
if cur_count > 0:
self.conn.commit()
self.text_browser.moveCursor(QTextCursor.End)
self.text_browser.append('執行成功')
else:
self.text_browser.moveCursor(QTextCursor.End)
self.text_browser.append('執行失敗，影響0條記錄')
8、代碼輸入框
- 顯示初始值
# 文本框
def set_text_edit(self):
font = QtGui.QFont()
font.setFamily("Times New Roman")
font.setPointSize(14)
self.text_edit.setFont(font)
self.cur.execute('show tables;')
db_len = self.cur.fetchone()
self.text_edit.setPlaceholderText('SELECT * FROM {};\nGO;\n\n按F5運行代碼'.format(db_len[0]))
9、清空按鈕與富文本瀏覽器
- 這兩個控制元件比較簡單，按一下清空代碼按鈕就在富文本瀏覽器中顯示資訊
# 富文本瀏覽器
def set_text_browser(self):
self.text_browser.setPlaceholderText('操作記錄：')
# 清空按鈕
def set_clear_button(self):
pass
# 清空按鈕左鍵
def clear_all(self):
self.text_edit.setText('')
self.text_browser.append('清空代碼區')
四、新建資料表對話框
1、添加控制元件
- 界面簡單，就用 Designer 添加相應控制元件
- 先弄成最多只能添加三個欄位
2、初始化對話框
class Ui_add_db_object(object):
def __init__(self):
super().__init__()
self.conn = pymysql.connect(host=gl_host, port=gl_port, user=gl_user, password=gl_pwd, db=gl_db)
self.cur = self.conn.cursor()
# 警告資訊
@staticmethod
def message_dialog(title, text):
msg_box = QtWidgets.QMessageBox(QtWidgets.QMessageBox.Warning, title, text)
msg_box.exec_()
3、設定控制元件屬性
- 設定字符長度最大值
- 系結確定按鈕和取消按鈕的信號
- 添加下拉選項
# 設定字符長度最大值
if self.label_1_comboBox.currentText() == 'char' or 'text' or 'varchar':
self.label_1_spinBox.setMaximum(255)
else:
self.label_1_spinBox.setMaximum(2 ** 20)
if self.label_2_comboBox.currentText() == 'char' or 'text' or 'varchar':
self.label_2_spinBox.setMaximum(255)
else:
self.label_2_spinBox.setMaximum(2 ** 20)
if self.label_3_comboBox.currentText() == 'char' or 'text' or 'varchar':
self.label_3_spinBox.setMaximum(255)
else:
self.label_3_spinBox.setMaximum(2 ** 20)
# 系結信號
self.retranslateUi(add_db_object)
self.add_no_pushButton_2.clicked.connect(add_db_object.close) # type: ignore
self.add_yes_pushButton.clicked.connect(lambda: self.add_true(add_db_object)) # type: ignore
QtCore.QMetaObject.connectSlotsByName(add_db_object)
# 添加資料型別下拉選項
item_attribute = ['', 'char', 'int', 'float', 'text', 'varchar']
self.label_1_comboBox.addItems(item_attribute)
self.label_2_comboBox.addItems(item_attribute)
self.label_3_comboBox.addItems(item_attribute)
4、確定按鈕信號槽
- 按下確定按鈕后，檢查輸入的資料是否符合規范，包括：
(1) 只有一個主鍵
(2) 資料表名和欄位名符合規范
(3) 是否填入了資料
def add_true(self, add_db_object):
try:
# 每個欄位的所有屬性添加進一個串列
label_1 = [self.label_1_lineEdit.text(), self.label_1_comboBox.currentText(), self.label_1_spinBox.text(),
self.label_1_checkBox.isChecked()]
label_2 = [self.label_2_lineEdit.text(), self.label_2_comboBox.currentText(), self.label_2_spinBox.text(),
self.label_2_checkBox.isChecked()]
label_3 = [self.label_3_lineEdit.text(), self.label_3_comboBox.currentText(), self.label_3_spinBox.text(),
self.label_3_checkBox.isChecked()]
print(label_1, label_2, label_3)
add_count = 0
add_item = []
word = r'^\w+$'
# 資料表名必填
if len(self.table_name_lineEdit.text()) == 0:
print(self.table_name_lineEdit.text())
match_tana = re.match(word, self.label_1_lineEdit.text())
self.message_dialog('警告', '資料表名必填')
return
if match_tana is None:
self.message_dialog('警告', '資料表名只能是英文、數字、下劃線')
return
# 主鍵只能有一個
if self.label_1_checkBox.isChecked() and self.label_2_checkBox.isChecked() \
or self.label_1_checkBox.isChecked() and self.label_3_checkBox.isChecked() \
or self.label_2_checkBox.isChecked() and self.label_3_checkBox.isChecked():
print('主鍵只能有一個')
self.message_dialog('警告', '主鍵只能有一個')
return
else:
# 每個欄位的欄位名、欄位型別、欄位長度必填
if "" not in label_1:
print(label_1)
# if len(self.label_1_lineEdit.text()) > 0:
match_1 = re.match(word, self.label_1_lineEdit.text())
if match_1 is None:
self.message_dialog('警告', '欄位名只能是英文、數字、下劃線')
return
# 判斷主鍵是否選上
for i in range(len(label_1) - 1):
add_item.append(label_1[i])
if self.label_1_checkBox.isChecked():
add_item.append('primary key')
else:
add_item.append(' ')
add_count += 1
if "" not in label_2:
print(label_2)
match_2 = re.match(word, self.label_2_lineEdit.text())
if match_2 is None:
self.message_dialog('警告', '欄位名只能是英文、數字、下劃線')
return
for i in range(len(label_2) - 1):
add_item.append(label_2[i])
if self.label_2_checkBox.isChecked():
add_item.append('primary key')
else:
add_item.append(' ')
add_count += 1
if "" not in label_3:
print(label_3)
match_3 = re.match(word, self.label_3_lineEdit.text())
if match_3 is None:
self.message_dialog('警告', '欄位名只能是英文、數字、下劃線')
return
for i in range(len(label_3) - 1):
add_item.append(label_3[i])
if self.label_3_checkBox.isChecked():
add_item.append('primary key')
else:
add_item.append(' ')
add_count += 1
if add_count == 0:
self.message_dialog('警告', '必填欄位名、欄位型別、欄位長度')
return
# 執行 SQL 陳述句
if len(add_item) == 4:
self.cur.execute(
'create table ' + self.table_name_lineEdit.text() + '(' + add_item[0] + ' ' + add_item[1] + '(' +
add_item[2] + ') ' + add_item[3] + ');')
self.conn.commit()
self.message_dialog('提示', '添加完成，重繪資料表')
self.cur.close()
add_db_object.close()
elif len(add_item) == 8:
