Hejka naklejka.
Tworzę obecnie API oparte o Flask - konkretniej moduł Flask-Restless (https://flask-restle...s.io/en/stable/) - dokumentację przejrzałem i zapoznałem się z możliwymi technikami.

Kod wygląda tak:

from flask_restless import APIManager
apimanager = APIManager(app, flask_sqlalchemy_db=db)
apimanager.create_api(Meal, methods=['GET', 'POST'])

Model Meal: 
 

class Meal(db.Model):
    __tablename__ = 'meals'
    __table_args__ = (
        Index('unique_meals', 'date', 'name', unique=True),
    )

    id = db.Column(Integer, primary_key=True)
    date = db.Column(Date, nullable=False)
    name = db.Column(String(200), nullable=False)
    restaurant_id = db.Column(ForeignKey(
        'restaurants.id', ondelete='CASCADE'), nullable=False, index=True)
    price = db.Column(String(8), nullable=False)

    restaurant = relationship('Restaurant')

Chodzi prawdopodobnie o wartość pobieraną z price mimo, że ustawiłem ją jako string (MySQLowski VARCHAR). 

Macie jakąś propozycję jak mógłbym to naprawić?

Witajcie.
O ile orientuje się w miarę dobrze w pobieraniu argumentów typu: 
/ban USER CZAS podczas tworzenia pluginu to mam pytanie dla bardziej zaawansowanych.

Powiedzmy, że chciałbym aby ktoś wpisał sobie komendę /zglos NICK po czym u góry wyświetli się mu (w miejscu domyślnym dla say) tekst: "Podaj treść skargi:" po czym miejsce na wpisanie tejże treści.

Czy macie jakiś pomysł jak to rozwiązać?
