如何修复'flask db.create_all（）error'？

Question

我有创建应用程序功能的flask init。我为我的unitests创建测试文件。在unitest类中添加setUp函数是我创建新的烧瓶应用程序并添加上下文，推送上下文。接下来我使用create_all（）函数创建测试数据库，并且，我启动测试文件，我有下一个错误：

in _execute_for_all_tables op(bind=self.get_engine(app, bind), **extra) 

TypeError：create_all（）得到了一个意外的关键字参数'forms'我没有'form'文件或模型或任何变量。

在flask_sqlalchemy / init.py MetaData（bind = None）中出现此错误之前，可能会有所帮助。

from flask import Flask

from blocker_application.database import db
from flask_migrate import Migrate
from flask_login import LoginManager
from flask_moment import Moment

migrate = Migrate()
login = LoginManager()
login.login_view = 'user.login'
moment = Moment()


def create_app(config_class=Config):
    app = Flask(__name__)
    app.config.from_object(config_class)

    db.init_app(app)
    migrate.init_app(app, db)
    login.init_app(app)
    moment.init_app(app)

我找到了决定。创建虚拟环境后，单元测试工作正常。
