Comment:
Running version Django==2.0.1
With Example form
{{{
class UpdateBalanceForm(forms.Form):
id = forms.ModelChoiceField(ProductPortfolio.objects.all(),
required=True)
balance = forms.DecimalField(decimal_places=2, max_digits=16,
required=True)
}}}
Running the following you get
{{{
form = UpdateBalanceForm({'id':1,
'balance':Decimal('5.420575188741E-12')})
form.is_valid()
False
form.errors
{'id': ['Select a valid choice. That choice is not one of the available
choices.'], 'balance': ['Ensure that there are no more than 16 digits in
total.']}
}}}
This is surprising because the value has 13 digits minus the scientific
notation
