Hi,
I think that I have found a bug on the system check: it accepts a
string as value for CharField.max_length argument.
It happens only if the string can be converted to int (e.g.
max_length='16'). Otherwise shows fields.E121 error (e.g.
max_length='foo').

fromdjango.db importmodels
classFoo(models.Model):
bar =models.CharField(max_length='16')
# following code raises an Exception
obj =Foo(bar='lorem ipsum')
obj.clean_fields()

Traceback:

>>> obj = Foo(bar='lorem ipsum')
