I want to add a record into the database, but the compiler returns me the error. I searched similar problems and I couldn't find the solution. class Packages(Base): __tablename__ = "packages"
id_package = Column(Integer, primary_key=True) name_of_package = Column(String) price = Column(Integer) def __init__(self, name_of_package, price): self.name_of_package = name_of_package self.price = price And then I am inserting the record. package = Packages('Economy', 5000) session.add(package) I've missed `id_package`, because it is Primary Key. I receive the following error. > Exception has occurred: TypeError > id() takes exactly one argument (0 given) > File "C:\***\<string>", line 2, in __ init __ File "C:\***\module.py", line 135, in <module> package = Packages('Economy', 5000) Line 2 = `from sqlalchemy import Column, Date, Integer, String` Any ideas? -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
