"""
Update the content of `self._errors`.
The `field` argument is the name of the field to which the errors
should be added. If its value is None the errors will be treated as
NON_FIELD_ERRORS.
The `error` argument can be a single error, a list of errors, or a
dictionary that maps field names to lists of errors. What we define as
an "error" can be either a simple string or an instance of
ValidationError with its message attribute set and what we define as
list or dictionary can be an actual `list` or `dict` or an instance
of ValidationError with its `error_list` or `error_dict` attribute set.
If `error` is a dictionary, the `field` argument *must* be None and
errors will be added to the fields that correspond to the keys of the
dictionary.
