model Integer fields (and derivatives) do not raise a ValidationError while other types do

[Romeo Mihalcea]

I have a model with Decimal fields, Boolean fields and some Integer fields. While testing with invalid data (I mostly supplied a string to these fields) I noticed that the integer fields do not raise a ValidationError while all of the other fields do so. Supplying a string to all Integer fields raise a ValueError instead which looks like all other fields have a basic validation in place while the Integers do not. I know I'm supposed to perform the validations before the data reaches the model but this is testing and I like to make sure everything is as intended.
