Question

I’m accepting dates from a wicket form – now I want query my DAO object with the dates and get the filters result. So the question is how can I pass parameters in models ? or Can I pass parameters in model?
The model by default call the getObject() method – which can’t take any parameter–
and if I use the model I can’t call the other method I created (getByDates(startDate,endDate))
what is the best way to pass parameters to DAO and get show the result in front end..
eg. Dataprovider / models etc …

      final  AbstractReadOnlyModel<List<LogParsed>> listModel =  new  AbstractReadOnlyModel<List<LogParsed>>()
        {
            @Override
            public List<LogParsed> getObject() {
                // TODO Auto-generated method stub
                return logParsedDao.findAll();
            }

            public List<SyslogParsed> getObject(Date startDate, Date endDate) {
                // TODO Auto-generated method stub
                return logParsedDao.findByDates(startDate, endDate);
            }
        };

Typically if the dates are not part of your domain model, but rather items you need in the user interface, then you can make them part of your page, panel or form, and then reference them in your anonymous inner class:

class MyPage extends Page {
    private Date startDate;
    private Date endDate;

    public MyPage() {
        Form form = new Form("form"){ ... submit logic etc ...};
        add(form);
        form.add(new DateField("startDate", new PropertyModel<Date>(this, "startDate")));
        form.add(new DateField("endDate", new PropertyModel<Date>(this, "endDate")));

        IModel<List<Item>> itemsModel = new LoadableDetachableModel<List<Item>>(){
            @Override
            protected List<Item> load() {
                return logParseDao.findByDates(startDate, endDate);
            }
        };
        add(new ListView<Item>("items", itemsModel) { ... });
    }
}
