This function allows the user to select values from a list of
possible values. The default is to select all the values:
>>> select_values(None, ['abc', 'def', 'hij'])
['abc', 'def', 'hij']
The user selects values with a comma-separated limit_string.
Prepending a minus sign to such a list denotes blacklist mode:
>>> select_values('-abc,hij', ['abc', 'def', 'hij'])
['def']
Without the leading -, the selection is in whitelist mode:
>>> select_values('abc,hij', ['abc', 'def', 'hij'])
['abc', 'hij']
In either case, appropriate errors are raised if on of the
user-values is not in the list of possible values. The name
parameter lets you make the error message more clear:
>>> select_values('-xyz,hij', ['abc', 'def', 'hij'], name="foobar")
Traceback (most recent call last):
...
UserError: Invalid foobar xyz
['abc', 'def', 'hij']
