In the included code exerpt, I am setting default values for form fields I
do not want the user to be able to modify, specifically 'user' and 'hits'.
I wrote a routine to remove any values from request.POST I don't want the
user to have control over. This is done by creating an instance of
MultiValueDict and copying over any values that the user is allowed to
post, returning the new MultiValDict instance.
### post_sanitize
def post_sanitize(post, fields):
safe_post = MultiValueDict({})
for f in fields:
if post.get(f):
safe_post[f] = post.get(f)
return safe_post
### excerpt from view.py
post_copy = request.POST.copy()
safe_post = post_sanitize(post_copy, valid_post_fields)
safe_post['user'] = 1
safe_post['hits'] = 0
errors = manipulator.get_validation_errors(safe_post)
When safe_post['hits'] is set to 0, I get an form error when I call
get_validation_errors, saying that 'hits' is not set
If i set 'hits' to 1, I get this error:
/usr/lib/python2.4/site-packages/Django-0.95-
py2.4.egg/django/forms/__init__.py in hasNoNewlines
