If you have changed any ``*.py`` files in
|
||||
``horizon/openstack_dashboard/contrib/sahara/content/data_processing``
|
||||
directory, Horizon will notice that and reload automatically. However
|
||||
changes made to non-python files may not be noticed, so you have to restart
|
||||
Horizon again manually, as described in step 6.

|

Using the Data Processing Dashboard without Keystone Registration
|
||||
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
|
||||
|
||||
**Note** These modifications are strictly for a development environment
|
||||
|
||||
If Sahara is not registered as a service with keystone, Horizon must be
|
||||
modified so that the Sahara URL can be known and so service-based
|
||||
permissions do not prevent the Data Processing dashboard from displaying.
|
||||
|
||||
|
||||
1. Modify ``openstack_dashboard/contrib/sahara/api/sahara.py``:
|
||||
|
||||
Add the following lines before ``def client(request)``:
|
||||
|
||||
**Note** you should replace the ip and port in ``SAHARA_URL`` with the
|
||||
appropriate values.
|
||||
|
||||
.. sourcecode:: python
|
||||
|
||||
SAHARA_URL = "http://localhost:8386/v1.1"
|
||||
|
||||
def get_sahara_url(request):
|
||||
|
||||
if SAHARA_URL:
|
||||
url = SAHARA_URL.rstrip('/')
|
||||
if url.split('/')[-1] in ['v1.0', 'v1.1']:
|
||||
url = SAHARA_URL + '/' + request.user.tenant_id
|
||||
return url
|
||||
|
||||
return base.url_for(request, SAHARA_SERVICE)
|
||||
..
|
||||
|
||||
After that modify ``sahara_url`` provided in ``def client(request):``
|
||||
|
||||
.. sourcecode:: python
|
||||
|
||||
sahara_url=get_sahara_url(request)
|
||||
..
|
||||
|
||||
|
||||
2. Modify ``openstack_dashboard/dashboards/project/dashboard.py``:
|
||||
|
||||
Overload the ``register`` method in ``class Project`` to programmatically
|
||||
remove ``data-processing`` permissions from all panels.
|
||||
|
||||
.. sourcecode:: python
|
||||
|
||||
@classmethod
|
||||
def register(cls, panel):
|
||||
if hasattr(panel, 'permissions'):
|
||||
panel.permissions = tuple(
|
||||
[perm for perm in panel.permissions if not perm.startswith(
|
||||
'openstack.services.data-processing')])
|
||||
super(Project, cls).register(panel)
|
||||
..
|
||||
|
||||
Alternatively the ``data-processing`` permissions can be removed
|
||||
manually from each panel under ``openstack_dashboard/contrib/sahara/content/data_processing``
|
||||
If you have changed any files in
|
||||
``{SAHARA_DASHBOARD_DIR}/sahara_dashboard/content/data_processing``
|
||||
directory, You will need to update horizon virtualenv by installing
|
||||
sahara-dashboard again as on step 7.
