arcgis javascript too many active WebGL contexts. Oldest context will be lost code example

Example 1: Superuser creation skipped due to not running in a TTY. You can run `manage.py createsuperuser` in your project to create one manually.

$ winpty python manage.py createsuperuser
//It should work by just appending 'winpty' before the command

Example 2: doest all the methos in interface need to implement c#

You have two choices:

- implement every method required by the interface
or
- declare the missing methods abstract in your class. This forces you
to declare your class abstract and, as a result, forces you to
subclass the class (and implement the missing methods) before you
can create any objects.
