Hello,
I'm trying to create a Dummy class of objects, something that will
return an empty string for any attribute. I'm making a very simple CMS
with Cherrypy/Sqlalchemy/Cheetah, and I have an HTML form template
that I use for editing/creating objects to save to the database. I'm
using just one form template, and I want to either pass an object from
the database to the template (for editing existing objects), or a
Dummy object which outputs empty strings for all the HTML form fields,
creating a blank form. Additionally, I'd like to be able to pass
keyword arguments to the Dummy() initialization which get turned into
attributes, so I can output various default values for the form fields.
What I've got so far handles non-existent attributes fine, but using
keywords to create attributes isn't working (attributes thus set still
output an empty string), and I'm not sure why. Here's the class:
class Dummy(object):
def __init__(self,**atts):
for k,v in atts.items():
self.k = v
def __repr__(self):
return ''
def __getattr__(self, attr):
return ''
>>> dum = Dummy(name='John')
>>> dum
>>> dum.nationality
''
>>> dum.name
''
__getattr__ says it only comes into play when an attribute is NOT
found, so I must be doing something wrong in the __init__ method...
Thanks in advance,
Eric
