The ```ValidationError`` has a ``code`` field that can be used in views to
determined what exactly failed during form validation. Unfortunately, the
list of error codes in not easily accessible from form. Actually, if I
want to recover the ``ValidationError.code``s for a form's particular
field, I must write the following:
{{{#!python
error_codes = [err.code for err in form.errors.get("field",
ErrorList()).data]
}}}
I propose to add a ``error_codes`` to the ``Form`` class as follows:
{{{#!python
@property
def errors_codes(self):
"""Return the list of error codes for each field of this form."""
if self._errors_codes is None:
self._errors_codes = {
field: [error.code for error in errors.data if error.code]
for field, errors in self.errors.items()
}
return self._errors_codes
}}}
