resources currently stored in NavalPlan database.
+Filter information on report
+----------------------------
+
+You are going to add a simple filter in interface to allow users to select what
+kind of resources are going to appear in the report: workers or machines.
+
+Steps:
+
+* Modify ``resourcesListReport.zul`` to add the following lines::
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+* Add following line in ``ResourcesListReportController``::
+
+ private Combobox resourcesType;
+
+* And modify ``getDataSource`` method in the same file::
+
+ @Override
+ protected JRDataSource getDataSource() {
+ Comboitem typeSelected = resourcesType.getSelectedItemApi();
+ String type = (typeSelected == null) ? "all" : (String) typeSelected
+ .getValue();
+
+ List dtos = resourcesListReportModel
+ .getResourcesListReportDTOs(type);
+ if (dtos.isEmpty()) {
+ return new JREmptyDataSource();
+ }
+
+ return new JRBeanCollectionDataSource(dtos);
+ }
+
+* This would mean that a new parameter appear in model method, so you would need
+ to modify ``IResourcesListReportModel`` to add the new parameter ::
+
+ List getResourcesListReportDTOs(String type);
+
+ And change ``getResourcesListReportDTOs`` method in
+ ``ResourcesListReportModel`` to get different information depending on the new
+ parameter::
+
+ @Override
+ @Transactional(readOnly = true)
+ public List getResourcesListReportDTOs(String type) {
+ List dtos = new ArrayList();
+
+ List resources;
+ if (type.equals("workers")) {
+ resources = resourceDAO.getWorkers();
+ } else if (type.equals("machines")) {
+ resources = resourceDAO.getMachines();
+ } else {
+ resources = resourceDAO.getResources();
+ }
+
+ for (Resource resource : resources) {
+ dtos.add(new ResourcesListReportDTO(resource));
+ }
+
+ return dtos;
+ }
+
+After applying these changes you will be able to filter the report depending on
+option selected by users in the interface.
+
+
+Send parameters to report
+-------------------------
+
+Sometimes you need to send parameters to be printed in the report. You are
+already doing it without noticing, for example, you are sending logo path. You
+can check ``getParameters`` method in ``NavalplannerReportController``.
+
+Now you are going to send a parameter to print a message specifying if you are
+printing all the resources or just workers or machines using the filter.
+
+Steps:
+
+* Override ``getParameters`` in ``ResourcesListReportController`` using the
+ following lines::
+
+ @Override
+ protected Map getParameters() {
+ Map result = super.getParameters();
+
+ result.put("type", resourcesType.getValue());
+ return result;
+ }
+
+* Modify report file ``resourcesListReport.jrxml`` with iReport to add the new
+ parameter and show it in some part of the report layout. You could use iReport
+ for this task, or, for example, add the following lines in XML file::
+
+
+
+ ...
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+ It is also needed to add the new label in ``.properties`` file::
+
+ type = Type:
+
+Now if you generate the report you will see the type of report you are
+generating, you can see more examples about how to send parameters in some of
+the other reports already implemented in NavalPlan.
