I accidentally delete a user from the group "Internal Users". After that user disappeared and also could not login to system.
I search and found that there is a field "share" at "res_users" table. It becomes "True" after deleting from user group. If I update it to "False" it Users come back to life. I have three questions to understand how this group works:
Is there a way to make this without updating the database?
If deleting from "Internal Users" group is a problem, is there a way to prevent user deleting record?
Is it possible to create a new user group and use it instead of "Internal Users" group? (I don't want to change this group's content)
Thanks.
