Hi List, and sorry for the double posting to the cherrypy list...
I have the compiled a simple template to index.py. I would like to
have a class that inherits this template and can thus know how to
display itself and transparently get to its attributes. Here is what
I tried (if I leave out the "object" inheritance, I get the same
thing):
The template is the following (compiled with cheetah-compile):
$header
blah blah blah
$footer
The python code is:
import index # the compiled template file
class Foo(index.index, object):
def __init__(self):
self.header = 'HEADER'
self.footer = 'FOOTER'
return None
foo = Foo()
print foo
I would like the last line to print the template with $header and
$footer filled in from the object attributes, but I get the following:
Traceback (most recent call last):
File "/opt/local/lib/python2.5/site-packages/cherrypy/_cprequest.py",
line 606, in respond
cherrypy.response.body = self.handler()
File "/opt/local/lib/python2.5/site-packages/cherrypy/_cpdispatch.py",
line 24, in __call__
return self.callable(*self.args, **self.kwargs)
File "foo.py", line 41, in __call__
return self.__str__()
File "/opt/local/lib/python2.5/site-packages/Cheetah/Template.py",
line 982, in __str__
def __str__(self): return getattr(self, mainMethName)()
File "index.py", line 73, in respond
if (not trans and not self._CHEETAH__isBuffering and not
callable(self.transaction)):
AttributeError: 'Index' object has no attribute '_CHEETAH__isBuffering'
My rationale is that here the object "index" is a complete entity in a
cherrypy tree: url, methods, and a template for display (there would
also be a database connection).
I would also like my child class be able to define its own __init__
method, so dropping that method and writing index.footer = 'footer'
(etc) won't cut it.
Could anyone give me pointers? Perhaps my design is wacked, perhaps I
need a little metaclass magic I don't know about, etc?
Thanks to all!
