Cheetah pre-compiled template usage
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
print tmpl
You need
print results
Additionally, your code has some formatting problems:
- don't escape the ${title} with a backslash
- you need
if __name__ == '__main__':instead ofif name == 'main':
