在瓶子中创建子项目

Question

我刚开始进行Python Web开发,并选择Bottle作为我的首选框架.

我正在尝试使用模块化的项目结构,因为我可以拥有一个"核心"应用程序,其中包含围绕它构建的模块,这些模块可以在设置期间启用/禁用(或者如果可能的话,即时启动... .不知道我怎么设置那个).

我的"主要"课程如下:

from bottle import Bottle, route, run
from bottle import error
from bottle import jinja2_view as view

from core import core

app = Bottle()
app.mount('/demo', core)

#@app.route('/')
@route('/hello/<name>')
@view('hello_template')
def greet(name='Stranger'):
    return dict(name=name)

@error(404)
def error404(error):
    return 'Nothing here, sorry'

run(app, host='localhost', port=5000)

我的'子项目'(即模块)是这样的:

from bottle import Bottle, route, run
from bottle import error
from bottle import jinja2_view as view

app = Bottle()

@app.route('/demo')
@view('demographic')
def greet(name='None', yob='None'):
    return dict(name=name, yob=yob)

@error(404)
def error404(error):
    return 'Nothing here, sorry'

当我进入http://localhost:5000/demo浏览器时,它显示500错误.瓶子服务器的输出是:

localhost - - [24/Jun/2012 15:51:27] "GET / HTTP/1.1" 404 720
localhost - - [24/Jun/2012 15:51:27] "GET /favicon.ico HTTP/1.1" 404 742
localhost - - [24/Jun/2012 15:51:27] "GET /favicon.ico HTTP/1.1" 404 742
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/bottle-0.10.9-py2.7.egg/bottle.py", line 737, in _handle
    return route.call(**args)
  File "/usr/local/lib/python2.7/dist-packages/bottle-0.10.9-py2.7.egg/bottle.py", line 582, in mountpoint
    rs.body = itertools.chain(rs.body, app(request.environ, start_response))
TypeError: 'module' object is not callable

文件夹结构是:

index.py
views (folder)
|-->hello_template.tpl
core (folder)
|-->core.py
|-->__init__.py
|-->views (folder)
|--|-->demographic.tpl

我不知道我在做什么(错误):)

任何人都知道如何/应该如何做？

谢谢!

您正在将模块"core"传递给mount()函数.相反,你必须将瓶子app对象传递给mount()函数,所以调用就像这样.

app.mount("/demo",core.app)

以下是mount()函数的正式文档.

mount(prefix, app, **options)[source]

将应用程序(Bottle或plain WSGI)挂载到特定的URL前缀.
例:

root_app.mount('/admin/', admin_app)

参数:
prefix - 路径前缀或mount-point.如果它以斜线结尾,则该斜杠是强制性的.
app - Bottle或WSGI应用程序的实例
