设置子项后，将父数据值设置为true

Question

我想自动将根模块视图设置为true，如果选择了子模块，请任何人帮我解决这个问题，请检查我附带的JSF和Managed Bean代码。

JSF代码

<p:dialog widgetVar="assignPermission" id="assignPermissionDlgId">
    <p:panel>
        <h:form id="form">
            <p:dataTable value="#{roleModule.modulesList}" var="modules"
                         id="tableId">
                <p:column headerText="Root Module ID:">
                    <h:outputText value="#{modules.moduleID}" />
                </p:column>
                <p:column headerText="Module ID:">
                    <h:outputText value="#{modules.rootID}" />
                </p:column>
                <p:column headerText="Module Description:">
                    <h:outputText value="#{modules.moduleDescription}" />
                </p:column>
                <p:column headerText="View">
                    <h:selectBooleanCheckbox id="view" value="#{modules.view}" />

            </p:dataTable>

            </p:confirmDialog>
        </h:form>
    </p:panel>
</p:dialog>

ManagedBean

    public void confirmMethod()
    {
        System.out.println(modulesList.size());

        PreparedStatement pst = null;
        Connection con = getConnection();
//      System.out.println("value check"+applicationShort);
        String insert="INSERT INTO role_module_mapping VALUES(?,?,?,?,?,?)";


        for(Module list : modulesList)
        {
            try {
                pst=con.prepareStatement(insert);
                pst.setInt(1, 0);
                pst.setInt(2, list.getModuleID());

                pst.setString(3, (list.isCreate())==true? "T" : "F");
                pst.setString(4, (list.isEdit())==true? "T" : "F");
                pst.setString(5, (list.isDelete())==true? "T" : "F");
                pst.setString(6, (list.isView())==true? "T" : "F");
                pst.executeUpdate();
//              System.out.println("Method called"+value);

            } catch (SQLException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }


    }


}

        $(PrimeFaces.escapeClientId('form:tableId')).on(

Answer 1

假设您正在使用父结构和子进程使用相同实体的树结构，我会做类似的事情：

<p:selectBooleanCheckbox id="view" value="#{modules.view}" widgetVar="ckBoxVar#{modules.rootID}" onchange="#{(modules.moduleID ne null) ? 'ckBoxVar' : ''}#{(modules.moduleID ne null) ? modules.moduleID : ''}#{(modules.moduleID ne null) ? '.check()' : ''}"  />

出于某种原因，我有这种强烈的感觉，当你写：

<p:column headerText="Root Module ID:">
    <h:outputText value="#{modules.moduleID}" />
</p:column>
<p:column headerText="Module ID:">
    <h:outputText value="#{modules.rootID}" />
</p:column>

你实际上是想说这个：

<p:column headerText="Root Module ID:">
    <h:outputText value="#{modules.rootID}" />
</p:column>
<p:column headerText="Module ID:">
    <h:outputText value="#{modules.moduleID}" />
</p:column>
