Doing this every time a user logs in probably has performance implications but that's a problem to care about when we'll hit it in the wild.

only if it has teamIDsToLeave, but yeah I agree.

The problem is more the oidc structure itself, that you "have" to check for changes "everytime" you sign in..

why not do this in one sql query?

You mean something like:

func RemoveUserFromTeamsByIds(s *xorm.Session, u *user.User, teamIDs []int64) (err error) {

	if len(teamIDs) < 1 {
		return nil
	}

	strSlice := make([]string, len(teamIDs))
	for i, num := range teamIDs {
		strSlice[i] = strconv.FormatInt(num, 10)
	}

	sql := fmt.Sprintf(`DELETE FROM team_members WHERE user_id = %d AND team_id IN (%v)`, u.ID, strings.Join(strSlice, ","))

	_, err = s.Exec(sql)

	return err

Yes, but with xorm:

	_, err = s.Where(builder.And(builder.Where("user_id = ?", u.ID), builder.In("team_id", teamIDs)).Delete(&TeamMember{})
	return err
Yes, but with xorm: ``` _, err = s.Where(builder.And(builder.Where("user_id = ?", u.ID), builder.In("team_id", teamIDs)).Delete(&TeamMember{}) return err ```

went for:

_, err = s.Where("team_id IN (?) AND user_id = ?", strings.Join(strSlice, ","), u.ID).Delete(&models.TeamMember{})

went for: `_, err = s.Where("team_id IN (?) AND user_id = ?", strings.Join(strSlice, ","), u.ID).Delete(&models.TeamMember{})`

That's still working agains the orm - makes things more complicated in the end.

Please use xorm's In function instead.

Something like this might work as well:

_, err = s.And("user_id = ?", u.ID).In("team_id", teamIDs).Delete(&TeamMember{})
	return err

This whole inner loop should be rewritten to something like this so that it's more idomatic go:

tm := models.TeamMember{TeamID: teamID, Username: u.Username}
err := tm.Delete(s, u)
if err != nil {
	return err
}

team, err := models.GetTeamByID(s, teamID)
if err != nil {
	return err
}

err = team.Delete(s, u)
if err != nil {
	return err
}

Also right now you'll only delete the team if deleting the member did not work, which does not really make sense.

Not sure if this is a good solution. Imagine one membership fails to get removed while the others get through. Then there's inconsistent state and the whole thing is not atomic anymore. I think we should instead return on the first error and let the caller deal with it.

okay, but won't it reach inconsistent state anyways?
Imagine the user is in 3 groups.
tm is deleted for group 1
tm is not deleted for group 2, because user is last member
tm won't be deleted for group 3, where user is not last member and should be removed.

or do you suggest to catch ErrCannotDeleteLastTeamMember and ask to sign out manually from that specific group(s) and sign out from other groups anyway?

I think it is intended behavior to sign out from teams when possible, and to leave teams as they are, where error is found. Maybe giving a hint to leave manually because you are last user.

Did I understand you correctly?

What's your difference between "signing out from a team" and "leaving a team"? Aren't the two the same?

Not if the whole db transaction is rolled back.

If the whole transaction is rolled back, then it might very challening to organize teams, because if a member sits on a team as last member, then the member cannot leave this team.
The suggestion would be to leave teams, if it is possible -> the team membership, where the user cannot be signed out because of
ErrCannotDeleteLastTeamMember{tm.TeamID, tm.UserID}
should be resolved manually then

to leave teams as they are, where error is found

Ah so "leave a team" in this context is "not deleting / modifying it"? Not "A user leaves a team"?

I guess I'm just understanding it differently :)

if a member sits on a team as last member, then the member cannot leave other teams.

Why would it do that? That's not what should happen, but how would being the last member of one team prevent that user to leave another team?

where the user cannot be signed out because of
ErrCannotDeleteLastTeamMember{tm.TeamID, tm.UserID}
should be resolved manually then

But resolving this manually would mean the user needs to manually remove the team, which they cannot do because the team was created from openid?

...is edited. I meant: the member cannot leave this team, if it is the last membership.

I think it is the responsibility of oidc admins to not let a team go blank without coordinating the potential destructive danger of it.
Therefore i would just delete the team + team_memberships.

no reason,
had claim VikunjaGroups more agnostic to specific data type.
