【问题描述】:
我正在尝试了解如何拆分在多个目录中使用 Mako 和 CherryPy 的项目。我准备了以下目录结构:
[FOLDER] /home/user/myapp
|- main.py
|- app.config
|- server.config
[FOLDER] /home/user/myapp/templates
[FOLDER] /home/user/myapp/templates/base
|- index.html
|- sidebar_menu.html
[FOLDER] /home/user/myapp/config
|- templates.py
在/home/user/myapp/templates 中会有不同的模板组织在目录中。
在/home/user/myapp/config 下,我有以下文件:templates.py,代码如下:
# -*- coding: utf-8 -*-
import mako.template
import mako.lookup
# Templates
templates_lookup = mako.lookup.TemplateLookup(
directories=[
'/templates',
'/templates/base',
],
module_directory='/tmp/mako_modules',
input_encoding='utf-8',
output_encoding='utf-8',
encoding_errors='replace'
)
def serve_template(templatename, **kwargs):
mytemplate = templates_lookup.get_template(templatename)
print(mytemplate.render(**kwargs))
在/home/user/myapp 下会有以下main.py 文件:
# -*- coding: utf-8 -*-
import os
import cherrypy
import mako.template
import mako.lookup
import config.templates
# Main Page
class Index(object):
@cherrypy.expose
def index(self):
t = config.templates.serve_template('index.html')
print(t)
return t
cherrypy.config.update("server.config")
cherrypy.tree.mount(Index(), '/', "app.config")
cherrypy.engine.start()
当我启动应用程序并访问 / 时,我收到以下消息:
500 Internal Server Error
The server encountered an unexpected condition which prevented it from fulfilling the request.
Traceback (most recent call last):
File "C:\Python37\lib\site-packages\mako\lookup.py", line 247, in get_template
return self._check(uri, self._collection[uri])
KeyError: 'index.html'
During handling of the above exception, another exception occurred:

"Cant locate template for uri %r" % uri)

Powered by CherryPy 18.1.0
因此,尽管我们提供了目录,但基本上 Mako 似乎无法找到 index.html。我想我不明白 Mako 在查找中的用途。
注意:程序实际上是在Windows中运行的,我上面使用了UNIX文件结构只是为了让文件结构更容易阅读。
Python 3.7.2
CherryPy 18.1.0
Mako 1.0.7
