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

Johannis259

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){
            rank=idx.row()+1;
            break;
        }
    }

    QModelIndexList indexList=clubsModelProxy->match(index(0,0),Qt::DisplayRole, QVariant::fromValue(clubName), -1, Qt::MatchFixedString);
    qDebug()<<indexList.count();
    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.

You're welcome !
