Question

我在ubuntu流浪盒中运行python

每当我运行 runserver 或 syncdb 时，我都会收到此错误。

应用程序未在数据库实例上注册且没有应用程序

完整筹码：

<div class="col-sm-4 rating">
                                    <input type="hidden" name="questionId[]" value="4"/>
                                    <input type="radio" class="career_ratings" id="career_star31" name="career_rating_answer[3]" value="1" />
                                    <label  for="career_star31" title=""></label>

                                    <input type="radio" class="career_ratings" id="career_star32" name="career_rating_answer[3]" value="2"/>
                                    <label  for="career_star32" title=""></label>

                                    <input type="radio" class="career_ratings" id="career_star33" name="career_rating_answer[3]" value="3"/>
                                    <label  for="career_star33" title=""></label>

                                    <input type="radio" class="career_ratings" id="career_star34" name="career_rating_answer[3]" value="4"/>
                                    <label  for="career_star34" title=""></label>
                                </div>

在manage.py中发生错误：

Traceback (most recent call last):   File "manage.py", line 41, in <module>
    models.PSABase.metadata.create_all(db.engine)   File "/usr/local/lib/python2.7/dist-packages/flask_sqlalchemy/__init__.py", line 922, in engine
    return self.get_engine()   File "/usr/local/lib/python2.7/dist-packages/flask_sqlalchemy/__init__.py", line 931, in get_engine
    app = self.get_app(app)   File "/usr/local/lib/python2.7/dist-packages/flask_sqlalchemy/__init__.py", line 957, in get_app
    'application not registered on db instance and no application' RuntimeError: application not registered on db instance and no applicationbound to current context

我说：

from pixelpin_auth_flask_sqlalchemy import models
models.PSABase.metadata.create_all(db.engine)

错误的地方应该是：

@manager.command
def syncdb():
    User.metadata.create_all(db.engine)
    from pixelpin_auth_flask_sqlalchemy import models
    models.PSABase.metadata.create_all(db.engine)

manager.add_command('server', Server(host='192.168.33.16'))
manager.add_command('shell', Shell(make_context=_make_context))

if __name__ == '__main__':
    manager.add_command("runserver", Server(
    use_debugger = True,
    use_reloader = True,
    host = '192.168.33.16'))
    manager.run()

应用程序未在db实例上注册而没有应用程序
