I cannot recreate any error like what you describe with the information you
have provided:
Python 2.5.1 (r251:54863, Jul 31 2008, 23:17:40)
[GCC 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from django import forms
>>> class IForm(forms.Form):
... nzint = forms.IntegerField(min_value=0,)
...
>>> iform = IForm(data={'nzint': -1})
>>> iform.is_valid()
False
>>> iform.errors
{'nzint': [u'Ensure this value is greater than or equal to 0.']}
>>>
Repeating myself for about the bazillionth time: snippets of the actual code
in use use and the full traceback of the error seen are much more likely to
get useful replies than brief word sketches of the code and the barest bones
of the debug information from the error. Alternatively, an attempt to
recreate the error with the minimal information you think is relevant might
reveal how the stripped-down case works and possibly provide a clue as to
what's different about the code exhibiting the error, allowing you to solve
the problem on your own.
