Python - TypeError：需要一個整數

Question

我正在嘗試創建一個數據庫來保持用戶和攀登者與用戶之間的一對多關系，以及用戶完成的攀爬。

class Climb(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    date = db.Column(db.DateTime)
    name = db.Column(db.String(64))
    flash = db.Column(db.Boolean)
    notes = db.Column(db.Text)
    type_of_climb = db.Column(db.String(32))
    difficulty = db.Column(db.String(5))
    location = db.Column(db.String(64))
    favorite = db.Column(db.Boolean)
    user_id = db.Column(db.Integer, db.ForeignKey('user.id'))

    def __init__(self, climb_date, name, flash, notes, type_of_climb, difficulty, location, favorite, user_id):
        set_date = datetime.strptime(climb_date, '%Y%m%d').date()
        self.date = set_date
        self.name = name
        self.flash = flash
        self.notes = notes
        self.type_of_climb = type_of_climb
        self.difficulty = difficulty
        self.location = location
        self.favorite = favorite
        self.user_id = user_id

我試圖在PyCharm中使用Python控制台測試數據庫。 我已經成功創建了一個用戶並嘗試向數據庫添加爬升但是在使用以下命令集時不斷收到“TypeError：需要一個整數”：

>>> from flask import Flask
>>> from app import app, db
>>> db.create_all()
>>> from app import User, Climb
>>> c = Climb('2015-05-02', 'Climb so high', 1, 'Made it happen', 'Trad', '5.8', 'Nepal', 0, 1)
Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "<string>", line 4, in __init__
  File "/home/logan/Desktop/DEV/git/Climb-On/climb-on-api/flask/local/lib/python2.7/site-packages/sqlalchemy/orm/state.py", line 269, in _initialize_instance
    return manager.original_init(*mixed[1:], **kwargs)
  File "/home/logan/Desktop/DEV/git/Climb-On/climb-on-api/app.py", line 50, in __init__
    self.flash = flash
TypeError: an integer is required

我對如何得到錯誤感到困惑（flash是傳遞的第三個參數，我的帳號1是一個整數）。

任何幫助深表感謝。

DBAlchemy可能需要DB中相應表的列不是正確的類型。
