Question

I want to add ABRecordRef to existing Group. Some how its not working. Here is my code:

-(void)addUsers:(NSMutableArray*)users toGroupID:(ABRecordID)groupID {

    CFErrorRef error = NULL;
    ABAddressBookRef addressBookRef = ABAddressBookCreate();

   // Get Group 
    ABRecordRef group = ABAddressBookGetGroupWithRecordID(addressBookRef,groupID);

    for (User *user in users) {

        int recordId = user.uniqID;

        ABRecordRef person = ABAddressBookGetPersonWithRecordID(addressBookRef,(ABRecordID)recordId);

        //add the new person to the record
        ABAddressBookAddRecord(addressBookRef, person, nil); 
        ABAddressBookSave(addressBookRef, &error);

        // add the group   
        ABAddressBookAddRecord(addressBookRef, group, &error); 
        ABAddressBookSave(addressBookRef, &error);

        // add the person to the group 
        ABGroupAddMember(group, person, &error);         
        ABAddressBookSave(addressBookRef, &error);

        //save the record
        ABAddressBookSave(addressBookRef, nil);

        if (!isMemberAdded) {
            [self showAlertWithTitle:@"Alert" andMessage:@"Some Error Occured While Adding User to Existing Group"];
        }
    }
    BOOL isMembersAddedToGroup = ABAddressBookSave(addressBookRef, nil); 
    if (isMembersAddedToGroup) {
        [self showAlertWithTitle:@"Alert" andMessage:@"Selected Members Added to Existing Group Successfully"];
    }
    else{
        [self showAlertWithTitle:@"Alert" andMessage:@"Some Error Occured While Adding User to Existing Group"];
    }
    CFRelease(addressBookRef);
}

Whenever I use above code & try to save it in existing group I get following message in console

CPSqliteStatementPerform: constraint failed for INSERT INTO ABGroupMembers (group_id, member_type, member_id) VALUES (?, ?, ?);
CPSqliteStatementReset: columns group_id, member_type, member_id are not unique for INSERT INTO ABGroupMembers (group_id, member_type, member_id) VALUES (?, ?, ?);

I am not getting what I am missing in above code.
Any knid of help is appreciated. Thanks

If we see the message:

CPSqliteStatementPerform: constraint failed for INSERT INTO ABGroupMembers (group_id, member_type, member_id) VALUES (?, ?, ?);
CPSqliteStatementReset: columns group_id, member_type, member_id are not unique for INSERT INTO ABGroupMembers (group_id, member_type, member_id) VALUES (?, ?, ?);

Also in documentation :

The ABAddressBook opaque type (whose instances are known as address
books) provides a programming interface to the Address Book—a
centralized database used by multiple applications to store personal
information about people

(So, internally, this error is caused due to incorrect sqlite query.)

It indicates that there is some issue with ABGroupAddMember or ABAddressBookAddRecord(addressBookRef, group, &error); call.

The problem can be: We have group and person references already with us when we callABAddressBookGetGroupWithRecordID and ABAddressBookGetGroupWithRecordID functions.

Now, when ABAddressBookAddRecord is executed for both( person and group) it is adding them to addressbook but not updating their UniqueIds(id for person and group ref.) so at the time of ABGroupAddMember function call it has person and group with same ids which are added in ABGroupMembers table.

Please, try to print recordId for person and group after you add them to address book(and before you add them to group). if recordsIds are not updated then that is the cause, and you will need to fetch record for new recordId. Also check whether the new person and group are being added to addresbook or not.
