Description

Scanning a workspace allows AntaresWeb to retrieve studies that were not already in its database
So it does not make sense to scan any managed folder.

However, it is possible using the front-end (little "target" icon at the very right of the screenshot below):

It is also possible to do so using the API.
If this happens, the back-end currently raises an Exception and the task fails.

2 things need to be implemented:

• The back office should not raise an Exception but simply log the fact that this doesn't make sense
• The front office should not display the little "target" icon when the folder to scan is a child of "default" workspace.

The back-end part is quite easy and already implemented in the linked PR, so it solves the API issue.

The front-office however could be more tricky as every information is gathered with the endpoint GET /studies when the user clicks on the Studies page and no other API call is raised when the user clicks on any folder.
