Question

Flask

Here I used if request.form["btn"] == "Changepass": to accept multiple forms on the same page

if request.method == 'POST':
            if(request.data):
                json = request.get_json(force=True)
                print(json["id"])
                cursor.execute(
                    "DELETE FROM domains WHERE id='" + json["id"] + "'")
                conn.commit()
            else:
                if request.form["btn"] == "Changepass":
                    newpass = str(request.form.get('newpass'))
                    newpass1 = str(generate_password_hash(newpass))
                    cursor.execute("UPDATE users SET Password='" +
                                newpass1 + "' WHERE id=?", (id,))
                    conn.commit()
                    session.clear()
                    return redirect('/logout')
                else:
                    if request.form["btn_adddomain"] == "Adddomain":
                        domain = str(request.form.get('domain'))
                        cursor.execute("SELECT * FROM domains WHERE domain=?", (domain,))
                        if cursor.fetchone() is None:
                            bot.send_message(
                                config.tc, f"Завка на добавление домена  {domain}")
                            cursor.execute(
                                f"INSERT INTO domains (user, domain) VALUES (?, ?)", (id, domain,))
                            conn.commit()
                        else:
                            return {
                                "success": "False",
                            }
                        return redirect("/domains")

Here is the html form

<form action="" method='post' id="AddDomainForm">
                        <span>Введите домен в формате "example.com"</span>
                        <p style="margin-top: 5px;">
                            <input required type="text" class="form__input" placeholder="Домен" name="domain"></p>
                </div>
                <div class="modal-footer">
                    <button type="submit" style="border-radius: 6px;" name="btn_adddomain" value="Adddomain">Добавить</button>

The problem is that the first condition returns

Traceback (most recent call last):
  File "/usr/local/lib/python3.9/dist-packages/flask/app.py", line 2091, in __call__
    return self.wsgi_app(environ, start_response)
