I find haw to add a user in this community :it is done by the method

UserServiceUtil.addGroupUsers(idGroup, addUserIds);

and this method added a line in the table users_groups this table mapped a user with a particular group

but I did not find how to delete this assignment

Hmm, what exactly do you mean by "update a line"?

hi,

I mean to change the assignement, change the user community,
change the idGroup for a particular user

thanks

You can use:

UserLocalServiceUtil.updateGroups(long userId, long[] newGroupIds)

If you look at the implementation you'll see that the logic unsets old groups and adds new groups.

		for (Group oldGroup : oldGroups) {
			long oldGroupId = oldGroup.getGroupId();

			oldGroupIds.add(oldGroupId);

			if (!ArrayUtil.contains(newGroupIds, oldGroupId)) {
				unsetGroupUsers(oldGroupId, new long[] {userId});
			}
		}

		for (long newGroupId : newGroupIds) {
			if (!oldGroupIds.contains(newGroupId)) {
				addGroupUsers(newGroupId, new long[] {userId});
			}
		}

thank you
but I have an older version I use liferay 4.2 and I did not find this method in UserLocalServiceUtil.

Sorry, if the equivalent method is not available in 4.2, then you'll just have to do it the long way by unsetting and adding groups for each user.

Another option is if you extend the 4.2 version of UserLocalServiceImpl in the EXT environment to create an upgradeGroups equivalent.
