Raphaël Badin has proposed merging lp:~rvb/maas/multifield-ui into lp:maas with
lp:~rvb/maas/multifield-api as a prerequisite.
Requested reviews:
Launchpad code reviewers (launchpad-reviewers)
For more details, see:
https://code.launchpad.net/~rvb/maas/multifield-ui/+merge/108979
This branch is a preparation branch for the follow-up branch which adds the
power_parameter field to the UI on a node edit page.
Because of the way Django handles empty values in forms, I had to adapt how
DictCharField and the related widget deal with empty values to be able to use
the same form in the API and in the UI. The value is considered empty if the
the value itself is in validators.EMPTY_VALUES or if all the subfields are
None. This allows us to set the subfields to the empty string (see test
test_PUT_updates_power_parameters_empty_string).
Also, the boolean field used to control whether or not the data should be
checked should be displayed (this is a control field used only in the API).
This is tested by the changed test in src/maasserver/tests/test_config_forms.py.
I've also added "required=False" to all the subfields in power_parameters.py
because at this stage I want the subfields to be very flexible.
Drive-by fix: Change templates/test_module.js to have a real test method.
