I'm testing Apache superset Dashboards, It s a great tool.
I added an external Database source (Oracle), and I created nice Dashboards very easily.
I would like to see my Dashboards updated regularly and automatically (3 times a day) in superset.
But my Dashboards are not updated.
I mean when a row is inserted into the Oracle Tables, if I refresh the Dashboard, I cannot view the new data in the Dashboard.
What is the best way to do it ?
=> Is there a solution / an option to force the Datasource to be automatically updated regularly ? in a frequency ? What is the parameter / option ? 
=> is there a solution to import in batch csv files (for instance in python), then this operation will update the Dashboard ?
=> other way ?
If you have examples to share... :-)
My environment: 
Superset is Installed on ubuntu 16.04 and Python 2.7.12.
Oracle is installed on another Linux server.
I connect from  google chrome to Superset.
Many thanks for your help
I just found the origin of my error... :-)
In fact I added records in the future (tomorow, the day after, ...)... 
And My dashboard was only showing all Records to the today date...
I inserted a record before, I refreshed and It appeared.
Thanks to having read me...
