I’ve just fired my project clean on new machine and when entering admin I got the following error, which indicates some syntax error in forms.py ( I believe admin’s forms). Anyone seen anything like this before ? :

Exception Type: TemplateSyntaxError at /admin/
Exception Value: Caught SyntaxError while rendering: invalid syntax (forms.py, line 227)
If the forms.py file mentioned in traceback is the one I think it is, then this is the line causing problems:
def __init__(self, *args, **kwargs):
self.father = kwargs.pop('parent', None) if kwargs else None
anything wrong here for python 2.4 ?
No, the error is in “/usr/lib/python2.4/site-packages/allaccess/rte_site/management/views.py”, which is a package you have installed yourself.
The reason it comes up where it does is because Django needs to import all views in order to reverse-lookup URLs, and importing this view gives a syntax error.
Edited after post update Yes, that ternary if syntax –
y if x else z– is only for Python 2.5 and above. For lower versions, you’d need to rewrite it as a standardifstatement block.
