forms.DecimalField

class DecimalField(**kwargs) [source]

• Default widget: NumberInput when Field.localize is False, else TextInput.
• Empty value: None
• Normalizes to: A Python decimal.
• Validates that the given value is a decimal. Leading and trailing whitespace is ignored.
• Error message keys: required, invalid, max_value, min_value, max_digits, max_decimal_places, max_whole_digits

The max_value and min_value error messages may contain %(limit_value)s, which will be substituted by the appropriate limit. Similarly, the max_digits, max_decimal_places and max_whole_digits error messages may contain %(max)s.

Takes four optional arguments:

max_value

min_value

These control the range of values permitted in the field, and should be given as decimal.Decimal values.

max_digits

The maximum number of digits (those before the decimal point plus those after the decimal point, with leading zeros stripped) permitted in the value.

decimal_places

The maximum number of decimal places permitted.
