我在用Tkinter。我有一个treeview,我在treeview中显示来自sqlite数据库的数据。但是,我添加了一个delete函数,可以从treeview中选择值,然后使用delete函数和按钮删除它们。它从树视图中删除,但不从数据库中删除。
def delete():
name2 = name_1.get()
phone2 = phone_number.get()
conn2 = sq.connect('Clients.db')
c2 = conn2.cursor()
selected_item = tree1.selection_set()
query = "DELETE FROM clients WHERE name=? AND phone=?"
c2.execute(query,(selected_item,))
conn2.commit()
tree1.delete(selected_item)
root = Tk()
root.geometry("800x800")
root.title("Hello")
root.configure(background="powder blue")
header = Label(root, text = "Clients Database", font=("arial",30,"bold")).pack()
con = sq.connect('Clients.db')
c = con.cursor()
c.execute("CREATE TABLE IF NOT EXISTS clients (name TEXT, phone TEXT)")
con.commit
tree1 = ttk.Treeview(root, height=10, columns=("Name", "PhoneNumber"), show=["headings"])
tree1.column('Name', anchor=W)
tree1.column('PhoneNumber', anchor=W)
tree1.heading('Name', text="Name")
tree1.heading('PhoneNumber', text="Phone Number")
我得到同样的错误:
Exception in Tkinter callback
Traceback (most recent call last):
File "/usr/lib/python3.6/tkinter/__init__.py", line 1705, in __call__
return self.func(*args)
File "/home/zizibaby/Desktop/Ingredients .py", line 38, in delete
c2.execute(query,(selected_item,))
