Laravel 5.1 firstOrNew与人际关系

Question

How can I use firstOrNew method with Laravel relationships.

I have the following relationship:

/**
 * The rows that belong to the timesheet.
 *
 * @return Object
 */
public function rowTimesheet()
{
    return $this->hasMany('App\Models\Timesheet\RowTimesheet');
}

I am trying to create a new row for the timesheet in the database using the following. I don't get any errors, but the row doesn't get inserted.

Any ideas?

/**
 * Create timesheet rows.
 *
 * @param $id
 * @param $row
 */
public function createTimesheetRow($id, $row) 
{
    return $this->timesheet->find($id)->rowTimesheet()->firstOrNew($row);
}

Hello about firstOrNew

model returned by firstOrNew has not yet been persisted to the database. You will need to call save manually to persist it

so you can try

public function createTimesheetRow($id, $row) 
{
    return $this->timesheet->find($id)->rowTimesheet()->firstOrCreate($row);
}

or

public function createTimesheetRow($id, $row) 
{
    $row = $this->timesheet->find($id)->rowTimesheet()->firstOrNew($row);
    return $row->save();
}

more info you can read in Laravel Docs
