Question

My folder root app.py looks like this

import application
if __name__ == '__main__':
application.app.run()

I have a folder called application with __init__.py and three folders: controllers, models and views.

The __init__.py Looks like this

__version__ = '0.1'
from application.controllers import QuotesView
from flask import Flask
app = Flask('application')
QuotesView.register(app)

My controllers folder has two files __init__.py and QuotesView.py as shown below: QuotesView.py

from flask.ext.classy import FlaskView, route
# we'll make a list to hold some quotes for our app
quotes = [
"A noble spirit embiggens the smallest man! ~ Jebediah Springfield",
"If there is a way to do it better... find it. ~ Thomas Edison",
"No one knows what he can do till he tries. ~ Publilius Syrus"
]

class QuotesView(FlaskView):
    @route('/')
    def index(self):
        return "<br>".join(quotes)
    def before_request(self, name):
        print("something is happening to a widget")

    def after_request(self, name, response):
        print("something happened to a widget")
        return response

And __init__.py looks like this:

import os
import glob
__all__ = [os.path.basename(
f)[:-3] for f in glob.glob(os.path.dirname(__file__) + "/*.py")]

When I run python app.py I get an attribute missing error:

Traceback (most recent call last):
  File "app.py", line 2, in <module>
import application
File "/home/ace/flask/application/__init__.py", line 5, in <module>
QuotesView.register(app)
AttributeError: 'module' object has no attribute 'register'

I cant seem to figure out where the error is though i feel its my importing. I am pretty new to python, so it might be something simple.

问题是您没有导入QuotesView课程。您导入了from application.controllers.QuotesView import QuotesView模块。因此，为了使其正常工作，您可以执行以下两项操作之一：

1.从模块中导入课程：

from application.controllers import QuotesView
QuotesView.QuotesView.register(app)

2.从导入模块访问该类

array1 = [{a: '1', b:'2', c:'3'}, {a: '4', b: '5', c:'6'}]
array2 = [{a: '1', b:'2', c:'10'}, {a: '3', b: '5', c:'6'}]

在我看来，方法1更清洁。
