Hi all, I'm glad to introduce you an advanced configuration of OpenStack settngs in Fuel UI. An appropriate blueprint<https://blueprints.launchpad.net/fuel/+spec/ui-settings-tab-validation> was implemented and the code merged.
Now we support the following cases: - validation of simple text settings using *regular expressions*. It can be email, password setting, etc. To take advantage of this feature a new *regex* attribute should be added into setting structure in openstack.yaml<https://github.com/stackforge/fuel-web/blob/master/nailgun/nailgun/fixtures/openstack.yaml#L144> file: regex: source: "^[a-z]+$", // RegExp object source error: "Invalid username" // Warning message to be displayed on UI - configuration of setting *dependencies*: - setting can depend on some environment attribute. For example, *Murano* component can't be installed on environment with Neutron networking. To set such dependency the following property should be added to setting structure: depends: - "cluster:net_provider": "neutron" - setting can depend on other settings. For example, in Storage section *Ceph RadosGW for objects (Swift API)* can not be activated without active *Ceph RBD for images (Glance)* setting. To configure such dependency the following change should be made into setting structure: depends: - "settings:storage.images_ceph": true - configuration of setting *conflicts:* - setting can conflict with other settings. For example, in Storage section *Cinder LVM over iSCSI for volumes *and* Ceph RBD for volumes (Cinder) *settings can not be activated at the same time. To configure such conflict the following change should be made into setting structure: conflicts: - "settings:storage.volumes_ceph": true So, *depends* and *conflicts* setting attributes are the lists of declarative conditions of the following format: "<model_name>:<model_attribute_path>": <model_attribute_value>. I want to notice that there are no separate fields with warning messages. Such warnings should be reflected in setting *description *attribute. Please see a design document<https://docs.google.com/document/d/1f_FKdzZdFh3KrUUrtAjTVScV7rn00pyxPeWwxb3jQ8k/edit?usp=sharing> for more detailed information and UI screenshots. Feel free for comments and asking questions.
