У меня есть таблица с базой данных sql, но происходит такая ошибка sqlite3.IntegrityError: NOT NULL constraint failed: chats.chat_two, мой код:
import sqlite3
class Database:
def __init__(self, database_file):
self.connection = sqlite3.connect(database_file, check_same_thread=False)
self.cursor = self.connection.cursor()
def add_queue(self, chat_id):
with self.connection:
return self.cursor.execute("INSERT INTO 'queue' ('chat_id') VALUES (?) ", (chat_id,))
def delete_queue(self, chat_id):
with self.connection:
return self.cursor.execute("DELETE FROM queue WHERE chat_id=?", (chat_id,))
def get_chat(self):
with self.connection:
chat = self.cursor.execute("SELECT * FROM queue", ()).fetchmany(1)
if (bool(len(chat))):
for row in chat:
return row[1]
else:
return False
def create_chat(self, chat_one, chat_two):
with self.connection:
if chat_two != 0:
#Создание чата
self.cursor.execute("DELETE FROM queue WHERE chat_id=?", (chat_two,))
self.cursor.execute("INSERT INTO chats (chat_one, chat_two ) VALUES (?,?)", (chat_one, chat_two))
return True
else:
#Становимся в очередь
return False
