[reportlab-users] Beginner's preppy puzzle: call to templatemodule.get() raises AttributeError: 'module' object has no attribute 'get'

The 'new' version has been in the code for many years. Which function
is available depends on the first line of the .prep file.
If you declare a module with {{def(arg1, arg2 etc)}} at the top, you
can only call it with get() not getOutput() e.g.
--------------newstyle.prep------------------
{{def(name,sex)}}
<!-- This is a 'new-style' .prep file with a function-like
declaration at the top. You must call the module's get()
function, not getOutput()-->
<html>
<head>
<title>{{name}}</title>
</head>
<body>
Hello. My name is {{name}} and I am
{{if sex=="f":}} a gal
{{elif sex=="m":}} a guy
{{else:}} neuter {{endif}}
</body>
</html>
-----------------------------------------------------
-----------newstyle_go.py-------------------
def run():
from preppy import getModule
module = getModule("newstyle.prep", verbose=1)
print module.get('fred', 'm')
if __name__=='__main__':
run()
----------------------------------------------
If we explained it incorrectly in the docs, I'll try to clear it up.
Meanwhile I have just committed the above two example files into the
preppy/demo directory, so if you pull from bitbucket you can try them.
Please let us know how you get on with preppy henceforth.
