Open Stack

Hi

I'm trying to customize a dashboard using devstack and I have an issue to register my dashboard

I have followed the tutorial

https://docs.openstack.org/developer/horizon/tutorials/dashboard.html

So I left the file with default parameters after using this commands

mkdir openstack_dashboard/dashboards/mydashboard

python manage.db -- startdash mydashboard    --target openstack_dashboard/dashboards/mydashboard

mkdir openstack_dashboard/dashboards/mydashboard/mypanel

python manage.db  -- startpanel mypanel  --dashboard=openstack_dashboard.dashboards.mydashboard --target=openstack_dashboard/dashboards/mydashboard/mypanel

I did not modify any file , the idea first was to see my dashboard created.

And finaly  I enabled my dashboard by creating a file _50_mydashboard.py with this

# The name of the dashboard to be added to HORIZON['dashboards']. Required.
DASHBOARD = 'mydashboard'

# If set to True, this dashboard will not be added to the settings.
DISABLED = False

# A list of applications to be added to INSTALLED_APPS.
ADD_INSTALLED_APPS = [
    'openstack_dashboard.dashboards.mydashboard',
]

I restart my virtual environment running on port 8000 and each time I tried to access to my dashboard I have this dump

This is my dashboard.py

from django.utils.translation import ugettext_lazy as _

import horizon


class Mydashboard(horizon.Dashboard):
    name = _("Mydashboard")
    slug = "mydashboard"
    panels = ()  # Add your panels here.
    default_panel = ''  # Specify the slug of the dashboard's default panel.


horizon.register(Mydashboard)


This my panel.py

from django.utils.translation import ugettext_lazy as _

import horizon
from openstack_dashboard.dashboards.mydashboard import dashboard

class Mypanel(horizon.Panel):
    name = _("Mypanel")
    slug = "mypanel"


dashboard.Mydashboard.register(Mypanel)


any idea will be appreciated
