Я работаю над базой данных с графическим интерфейсом, я сделал метод вставки и удаления, связанный с базой данных, сейчас я работаю над созданием метода поиска, но, к сожалению, не работаю из-за неожиданной ошибки. Код немного длинноват:
import sqlite3
from Tkinter import *
global all,root, main_text, num_ent, nom_ent, search_ent
def showall():
all = True
con = sqlite3.connect("repertoire.db")
cur = con.cursor()
request = 'select * from blinta'
cur.execute(request)
table = str(cur.fetchall()).replace(')', '\n').replace('(', '').replace(',', '').replace('[', '').replace(']', '')
return table
con.commit()
con.close()
def delete():
con = sqlite3.connect("repertoire.db")
cur = con.cursor()
request = ' DELETE FROM blinta WHERE id=?'
cur.execute(request, (ident.get(),))
con.commit()
con.close()
main_text.configure(state='normal')
main_text.delete(1.0, END)
main_text.insert(1.0, showall())
main_text.configure(state='disabled')
ident.delete(0,END)
def insert():
con = sqlite3.connect("repertoire.db")
cur = con.cursor()
request = 'insert into blinta (nom,numero) values(?,?)'
cur.execute(request, (nom_ent.get(), num_ent.get()))
con.commit()
con.close()
main_text.config(state='normal')
main_text.delete(1.0, END)
main_text.insert(1.0, showall())
main_text.config(state='disabled')
num_ent.delete(0, END)
nom_ent.delete(0, END)
def search():
all=False
con = sqlite3.connect("repertoire.db")
cur = con.cursor()
request = "select * from blinta where nom = ?"
noun = search_ent.get()
args=(noun,)
cur.execute(request,args)
selected = str(cur.fetchall()).replace(')', '\n').replace('(', '').replace(',', '').replace('[', '').replace(']', '')
return selected
con.commit()
con.close()
root = Tk()
root.config(bg='#D2B024')
root.geometry('450x650+900+0')
root.minsize(450, 650)
root.maxsize(450, 650)
main_text = Text(root, bg='#CBCAC5', fg='black', width=30, height=40, state='normal')
main_text.grid(column=1, row=1, rowspan=50, padx=9, pady=3)
main_text.delete(1.0, END)
if all == True :
main_text.insert(1.0, showall())
else :
main_text.insert(1.0, search())
main_text.config(state='disabled')
nomlbl=Label(root,text='Enter noun to insert',bg='#D2B024').grid(row=1,column=2)
nom_ent = Entry(root)
nom_ent.grid(row=2, column=2)
num_lbl=Label(root, text='Enter number to insert', bg='#D2B024').grid(row=3, column=2)
num_ent = Entry(root)
num_ent.grid(row=4, column=2)
insert_btn = Button(relief='flat', fg='black', width=7,
text='insert', font=("heveltica Bold", 15),
command=insert).grid(row=5, column=2,
columnspan=2, padx=50)
Label(root,text='_______________________',bg='#D2B024').grid(row=6,column=2)
idlbl=Label(root,text='Enter id to delete',bg='#D2B024').grid(row=7,column=2)
ident=Entry(root)
ident.grid(row=8,column=2)
delete_btn = Button(relief='flat', fg='black', width=7,
text='delete', font=("heveltica Bold", 15),
command=delete).grid(row=9, column=2,
columnspan=2, padx=0)
Label(root,text='_______________________',bg='#D2B024').grid(row=10,column=2)
search_lbl=Label(root,text='Enter noun to search',bg='#D2B024').grid(row=11,column=2)
search_btn = Button(relief='flat', fg='black', width=7,
text='search', font=("heveltica Bold", 15),
command=search).grid(row=13, column=2,
columnspan=2, padx=0)
global search_ent
search_ent = Entry(root)
search_ent.grid(row=12, column=2)
root.mainloop()
Вся проблема связана с функцией поиска, где запись search_ent не определена, и я уверен, что она находится в глобальной области. Ошибка:
Traceback (most recent call last):
