Searching a QString in QSqlRelationalTableModel witch match doesn't return a result

  • Hello,

    What am I doing wrong? I have been looking for a solution for quite some time now. The first part of the code works (search in a for loop for a QString in a model). The second part should do the same but doesn't return any valid index.

    ClubsModel is subclassed from QSqlRelationalTableModel. ClubsModelProxy from QSortFilterProxyModel.

    int ClubsModel::getRank(const int clubId)
        int nrofrows = clubsModelProxy->rowCount();
        int rank=0;
        QString clubName=data(index(clubId, CLUBNAME, QModelIndex()), Qt::DisplayRole).toString();
        for (int row = 0; row < nrofrows; ++row) {
            QModelIndex idx=clubsModelProxy->index(row,CLUBNAME,QModelIndex());
            if (clubsModelProxy->data(idx).toString()==clubName){
        QModelIndexList indexList=clubsModelProxy->match(index(0,0),Qt::DisplayRole, QVariant::fromValue(clubName), -1, Qt::MatchFixedString);
        return rank;

    What do I overlook?

    Hi and welcome to devnet,

    Is CLUBNAME's value 0 ?

  • Thank you! CLUBNAME is not 0. CLUBNAME is defined as const int CLUBNAME=2. It's refering to the third row of the model. That row contains club names.
