SearchError

class tw.dynforms.widgets.SearchError

strip_wo_markers

tw.dynforms.widgets.strip_wo_markers(val)

Remove WriteOnlyMarker instances from a dict/list structure. Where the marker is a value in a dictionary, the corresponding key is removed. Note: this is done separately from the validator, as an implementation details in TurboGears means a validator cannot reliably remove a key from a dictionary. This may be removed in future, if a workaround is found.
