AttributeError：'dict'对象没有属性'__name__'

Question

我正在尝试运行Flask脚本，但是出现以下错误AttributeError: 'dict' object has no attribute '__name__'。如何解决此错误？

编辑：我已经添加了entry_views.py和entry_models.py文件。希望它们可以使问题更加清晰

这是错误日志

这些是我正在使用的文件

run.py

import os
from werkzeug.contrib.fixers import ProxyFix 
from application import create_app


if __name__ == '__main__':
    app = create_app('default')
    app.wsgi_app = ProxyFix(app.wsgi_app)
    port = int(os.environ.get("PORT", 5000))
    app.run(host='0.0.0.0', port=port, debug=True)

您的代码应像这样（小写d）

api = Namespace('entries', description='Operations on entries')

而不是：

api = Namespace('entries', Description='Operations on entries')

看着code examples 似乎与众不同
