Я начинаю простой проект, в котором я пытаюсь создать crud и дать разрешения некоторым пользователям.
Я программирую в python-flask, и моя база данных - Postgres.
Python версия - 3.6.5 /
Postgres - 10,3 /
Колба 0.12.2
Когда я пытаюсь добавить пользователя в свою базу данных, это выдает мне эту ошибку:
__init__() принимает 1 позиционный аргумент, но 3 получили
add_user.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>This is a tittle </title>
</head>
<body>
<form method="POST" action="/post_user">
<label> Email: </label>
<input id="email" name ="email" type="text" />
<label> Password: </label>
<input id="password" name ="password" type="password" />
<input type="submit" />
</form>
</body>
</html>
