Append fields not included in the list in the default order for backward compatibility with subclasses not overriding field_order. If field_order is None, keep all fields in the order defined in the class. Ignore unknown fields in field_order to allow disabling fields in form subclasses without redefining ordering.

The `field` argument is the name of the field to which the errors should be added. If it's None, treat the errors 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. An "error" can be either a simple string or an instance of ValidationError with its message attribute set and a "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. � error_dictNzbThe argument `field` must be `None` when the `error` argument contains errors for multiple fields.z '%s' has no field named '%s'.r� r� )r r r& � TypeErrorr� r � error_listr! rc rE rJ r1 r2 r> rB rw � cleaned_data)rN r` rj r� r r r � add_error2 s. � � ��zBaseForm.add_errorc s2 || j v o� d u pt� fdd�| j �� | D ��S )Nc 3 s � | ]}|j � kV qd S rQ ��code)r rj r� r r � <genexpr>d s � z%BaseForm.has_error.<locals>.<genexpr>)rc �any�as_data)rN r` r� r r� r � has_errora s �zBaseForm.has_errorc C sF t � | _| js dS i | _| jr| �� sdS | �� | �� | �� dS )zY Clean all of self.data and populate self._errors and self.cleaned_data.
