For performance reason as suggested here, I am studying how to used the pr-compiled template.

I edit hello.tmpl in template directory as

#attr title = "This is my Template"
<html>
    <head>
        <title>\${title}</title>
    </head>
    <body>
        Hello \${who}!
    </body>
</html>

then issued cheetah-compile.exe .\hello.tmpl and get the hello.py

In another python file runner.py, I have:

#!/usr/bin/env python

from Cheetah.Template import Template
from template import hello
def myMethod():
    tmpl = hello.hello(searchList=[{'who' : 'world'}])
    results = tmpl.respond()
    print tmpl


if __name__ == '__main__':
    myMethod()

But the outcome is

<html>
    <head>
        <title>${title}</title>
    </head>
    <body>
        Hello ${who}!
    </body>
</html>

Debugging for a while, I found that inside hello.py:

def respond(self, trans=None):



    ## CHEETAH: main method generated for this template
    if (not trans and not self._CHEETAH__i开发者_如何学PythonsBuffering and not callable(self.transaction)):
        trans = self.transaction # is None unless self.awake() was called
    if not trans:
        trans = DummyTransaction()

it looks like the trans is None, so it goes to DummyTransaction, what did I miss here? Any suggestions to how to fix it?

Your main problem is that in runner.py inside myMethod() instead of
