Hi Collin

I'm using postgresql db, I' ve attached my views, forms and models. I' ve thought to do the ModelForm when I solve this problem, thanks for your advice!

Thank you very much!

Hello everybody, I've a problem with DecimalField at Forms. I've a long form in my template and I want to left some fields in blank. I've declared these fields with
required=False, but when I submit the form I receive this error: 'This value must be a decimal number'.

I've tried to declare blank=True, null=True in respective fields in models.py and make a syncdb but it continues without works

Does somebody know how could I solve this problem?

Thank you very much!
