Parent site could be deleted without warning about children.

[camillemonchicourt]

OK indeed. I am not sure if a course can exist without a parent site... Maybe we should protect it ?

[babastienne]

Yes, the solution would be to protect the deletion when there is an existing parent site attached to the course object.

[numahell]

To get around this problem, you can access directly to edit page, and associate at least a parent site.

Edit page is like /course/edit/{pk}

A course can be a child of 1 or several parent_sites. To fix this problem, we could protect deletion of a site, or fix detail view.

[babastienne]

Fixed in release 2.100.0. Deletion is protected when there is a child associated to the outdoor site.
