max_value rule not matching Django validation with DecimalField #7

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Set a max_value on DecimalField
2. Field is passed by JavaScript but fails django's validation

It looks like this might be a problem in Django. Investigation is required.

With a DecimalField the min and max values must be passed in as decimal.Decimal
classes. There is no type checking on the passed value. A float will be 
accepted in
your form but (Decimal('12.1') > 13) will return true and validation fails.

Some additional casting was required as the jsonencoder got itself into a 
continuous
loop attemping to serialize a decimal.Decimal.

ajax_fields.AjaxField.add_rule now has a cast option that accepts a function to 
do
type conversion on the rule value.
