We collected the failures but didn't report it back. This changes the API of most delete commands so rather than returning a boolean it returns a dict with the only current key as failed. This also adds a new parameter flag, suppress_empty. This will try to not print values that are empty if included. This makes the output of the delete commands a bit prettier. ticket 687

|
|
Simple description of a member in the return value ``dict``.
|
|
|
|
This class controls both the type of object being returned by
|
|
a command as well as how the output will be displayed.
|
|
|
|
For example, this class defines two return results: an entry
|
|
and a value.
|
|
|
|
>>> from ipalib import crud, output
|
|
>>> class user(crud.Update):
|
|
...
|
|
... has_output = (
|
|
... output.Entry('result'),
|
|
... output.value,
|
|
... )
|
|
|
|
The order of the values in has_output controls the order of output.
|
|
If you have values that you don't want to be printed then add
|
|
``'no_display'`` to flags.
|
|
|
|
The difference between ``'no_dipslay`` and ``'no_output'`` is
|
|
that ``'no_output`` will prevent a Param value from being returned
|
|
at all. ``'no_display'`` will cause the API to return a value, it
|
|
simply won't be displayed to the user. This is so some things may
|
|
be returned that while not interesting to us, but may be to others.
|
|
|
|
>>> from ipalib import crud, output
|
|
>>> myvalue = output.Output('myvalue', unicode,
|
|
... 'Do not print this value', flags=['no_display'],
|
