PF Filtering a Datatable column which contains a date

Question

I have a column in a datatable and I want to add a filter with this code:

Answer 1

For simpler solution you just need to add a placeholder for a date with String as data type for filterBy component usage.

Steps:

Create a new transient property in the model class.

@Transient
private String dateForFilter;
public String getDateForFilter() {
 return dateForFilter;
}
public void setDateForFilter(String dateForFilter) {
 this.dateForFilter = dateForFilter;
}

Create the logic below before returning the data model.

public List<Item> getDataModel() {
   List<Item> lstItem = serviceClass.loadItem(userid);
   for (Item item : lstItem) {
      DateFormat dateFormat = null;
      Date date = item.getDate;
      dateFormat = new SimpleDateFormat("MM/dd/yyyy kk:mm");
      item.setDateForFilter(dateFormat.format(date));
   }

   return lstItem;
}

Update your XHTML to use the dateForFilter property.

<p:column filterBy="#{item.dateForFilter}">
  <f:facet name="header">
    Transaction Date
  </f:facet>
  <h:outputText value="#{item.dateForFilter}" />
</p:column>

Note: You can only use this if you're not using the date to update the content of the model class.

HTH.

There is no ready-made date filter mechanism in primefaces yet, but there is a possibility to filter by date using a custom filter. You will have to define a header facet for your column and use ajax calls for "manual" filtering, but it does work:

<column>
  <f:facet name="header">DateRange
    <div>
      <p:calendar id="from" value="#{bean.from}" styleClass="calendarFilter">
        <p:ajax event="dateSelect" listener="#{ctrlr.filterDates()}" update="dataTableId"/>
      </p:calendar>
      <p:calendar id="to" value="#{bean.to}" styleClass="calendarFilter">
        <p:ajax event="dateSelect" listener="#{ctrlr.filterDates()}" update="dataTableId"/>
      </p:calendar>
    </div>
  </f:facet>
