是否可以在Life ray中将liferay ui:搜索容器行设置为不可编辑？

Question

我有一个页面，需要在自定义portlet中为用户设置并分配站点角色。因此，我能够在一个列表中获取“用户现有角色”，并在另一个列表中获取所有“可用站点角色”。那么，我该如何对分配给用户的行进行调整或任何验证，以使其不可编辑。比方说（我们有四个站点类型的角色，即站点管理员、站点所有者、站点成员和站点内容审阅者，现在相应的用户已经分配了站点管理员角色。因此，现在在搜索容器行中，我需要将站点管理员行设置为不可编辑，因为用户已经具有此角色）。我的代码如下，

 <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
    <%@include file="/html/users/init.jsp"%>

    <portletefineObjects />
             <%
List<Role> siteRoleList = (List) request.getAttribute("allsiteRolesList");   
List<Role> existingRoles = (List) request.getAttribute("existingRoles");     
String sel_userID = renderRequest.getParameter("sel_userID");
String backURL = ParamUtil.getString(request, "backURL");
            %>
            <%! 
                    List<Role> roles = null;
                    int totalNoOfroles=0;
                    String value = null;
            %>
            <%
            totalNoOfroles = siteRoleList.size();        
            roles = siteRoleList;
            %> 

    <liferay-ui:header backURL="<%= backURL %>" title="Available Site Roles" />

            <liferay-ui:search-container delta="5" emptyResultsMessage="no-site-roles-were-found" rowChecker="<%= new RowChecker(renderResponse) %>" >
            <liferay-ui:search-container-results
                    results="<%= ListUtil.subList(roles,searchContainer.getStart(),searchContainer.getEnd()) %>"
            total="<%= totalNoOfroles %>">    
        </liferay-ui:search-container-results>
            <liferay-ui:search-container-row className="com.liferay.portal.model.Role" keyProperty="roleId"        modelVar="role">

                    <liferay-ui:search-container-row-parameter name="roleIds" value="<%= role.getRoleId() %>"></liferay-ui:search-container-row-parameter>
                    <liferay-ui:search-container-row-parameter name="userIds" value="<%= sel_userID %>"></liferay-ui:search-container-row-parameter>
                    <liferay-ui:search-container-column-text name="title" value="<%= role.getName()%>" />
            <liferay-ui:search-container-column-text name="type" value="<%= role.getTypeLabel() %>">
            </liferay-ui:search-container-column-text>

            <liferay-ui:search-container-column-text name="description" value="<%= role.getDescription() %>">
            </liferay-ui:search-container-column-text>

                    <liferay-ui:search-container-column-jsp align="right" path="/html/users/user_assign_site_role_actions.jsp" />

            </liferay-ui:search-container-row>
            <liferay-ui:search-iterator />
    </liferay-ui:search-container>
    <liferay-ui:search-container delta="5" emptyResultsMessage="no-users-were-found" />

动作类：

 public void assignUserSiteRoles(ActionRequest request, ActionResponse response) throws com.liferay.portal.kernel.exception.PortalException, com.liferay.portal.kernel.exception.SystemException{
                    String sel_userID = ParamUtil.getString(request, "selectedId");
                    long userid = Long.valueOf(sel_userID);
                    String backURL = ParamUtil.getString(request, "backURL");
                    ThemeDisplay themeDisplay = (ThemeDisplay)request.getAttribute(WebKeys.THEME_DISPLAY);
                    long companyId = themeDisplay.getCompanyId();
                    long mySite =  themeDisplay.getSiteGroupId();
                    List<Role> allsiteRolesList = new ArrayList<Role>();
List<Role> existing roles = new ArrayList<Role>(); 


                    List<UserGroupRole> userGroupRoleList = UserGroupRoleLocalServiceUtil.getUserGroupRoles(userid, mySite);
                                if (userGroupRoleList != null) {
                                for (UserGroupRole userGroupRole : userGroupRoleList) {
                                    /* Get Role object based on userGroupRole.getRoleId() */
                                    Role role = RoleLocalServiceUtil.getRole(userGroupRole.getRoleId());
                                    if(role.getTypeLabel().equalsIgnoreCase("Site"))
                                {
                                 existingroles.add(role);             
                                }

                                }
                            }

                    List<Role> rolesList = RoleLocalServiceUtil.getRoles(companyId);
                    if (rolesList != null) {
                for (Role role : rolesList) {  
                                if(role.getTypeLabel().equalsIgnoreCase("Site"))
                                {
                                        allsiteRolesList.add(role);
                                }
                    }
                }


                    request.setAttribute("allsiteRolesList", allsiteRolesList);
                    response.setRenderParameter("sel_userID", sel_userID);
                    response.setRenderParameter("backURL", backURL);
                    response.setRenderParameter("mvcPath","/html/users/assign_user_site_roles.jsp");
              }

在我的代码中，siteRoleList包含所有可用角色的列表，existingRoles列表包含已分配给相应用户的角色。那么，如何才能只对那些用户没有该角色的行进行编辑呢。

actionJSP

<%@ include file="/html/users/init.jsp" %>

<%
ResultRow resultRow = (ResultRow)request.getAttribute(WebKeys.SEARCH_CONTAINER_RESULT_ROW);
Role role = (Role)resultRow.getObject();
String rowUserId = (String)resultRow.getParameter("userIds");
%>

<liferay-ui:icon-menu>  

  <portlet:actionURL name="UserSiteRoleAssign" var="UserSiteRoleAssign">
          <portlet:param name="selectedId" value="<%=String.valueOf(role.getRoleId()) %>" />
          <portle:pgaram name="rowUserId" value="<%= rowUserId %>" />
  </portlet:actionURL>
  <liferay-ui:icon iconCssClass="icon-signin" message="Assign Role" url="<%= UserSiteRoleAssign.toString() %>" />
</liferay-ui:icon-menu>

有什么建议吗。。

我不确定你如何评估条件来检查某些用户是否具有特定的角色。

无论如何，在你的actionJSP中，如果你能通过检查存在的角色列表来识别被选中的用户具有特定的角色，如下所示，应该可以为你做到这一点：

<%
ResultRow resultRow = (ResultRow)request.getAttribute(WebKeys.SEARCH_CONTAINER_RESULT_ROW);
Role role = (Role)resultRow.getObject();
String rowUserId = (String)resultRow.getParameter("userIds");

/* Get user existingRoles list here. */
boolean hasSiteRole = false;

for(Role userRole : existingRoles){
    if(userRole.getRoleId() == role.getRoleId())
        hasSiteRole = true;
}


%>

<liferay-ui:icon-menu>
    <portlet:actionURL name="UserSiteRoleAssign" var="UserSiteRoleAssign">
        <portlet:param name="selectedId" value="<%=String.valueOf(role.getRoleId()) %>" />
        <portle:pgaram name="rowUserId" value="<%= rowUserId %>" />
    </portlet:actionURL>

    <%
        String url = !hasSiteRole ? UserSiteRoleAssign.toString() : "javascript: void();";
        String styleClass = !hasSiteRole ? "icon-signin" : "icon-signin-diabled";
    %>

    <liferay-ui:icon iconCssClass="<%=styleClass %>" message="Assign Role" url="<%=url %>" />
</liferay-ui:icon-menu>

基于hasSiteRole属性，您可以控制图标的href、类或呈现。你也可以在主视图上查看。如果用户在existingRoles列表中已经存在某个角色，则将图标和样式类隐藏为禁用状态。

注意：这只是一个想法，你要给它具体的实施。
