如何从DSpace中的反馈页面的修改版本中获得引荐页面(项目)的标题? [英] How can I get the title of the referring page (item) from a modified version of feedback page in DSpace?

问题描述

如何像在jspui中的推荐此商品"中那样，从修改后的反馈页面中获取商品的标题?我也希望生成页面的结果URL，例如 http://example. com/feedback?handle = 123456789/123 .我在上一篇帖子的评论中提出了此要求，但我不知道如何使用HandleManager.我已经使用itemRequestForm的部分代码尝试了很多次，但是我总是会得到空指针错误.

How can I get the title of an item from a modified version of the feedback page just like in the "Recommend this item" in jspui? I'm hoping also to generate the resulting url of the page to be like http://example.com/feedback?handle=123456789/123. I've asked this from a comment in my previous post but I don't know how to use the HandleManager. I've tried many times using part of the code from itemRequestForm but I always get null pointer error.

    DSpaceObject dso = HandleUtil.obtainHandle(objectModel);
    if (!(dso instanceof Item)) {
        return;
    }
    Request request = ObjectModelHelper.getRequest(objectModel);
    boolean firstVisit=Boolean.valueOf(request.getParameter("firstVisit"));

    Item item = (Item) dso;

我还尝试查看/ViewArtifacts/sitemap.xmap，但现在我无法找出我所缺少的东西.

I also tried to looked in /ViewArtifacts/sitemap.xmap but right now it is beyond me to figure out what I am missing.

我认为在这里发布太久了.

I Think its too long to post here.

检查SolicitarCorreccionForm以显示标题和想要的内容，使用其他响应从句柄获取数据，而不是:

Check SolicitarCorreccionForm to show the title and what you want using my other response to get the data from the handle and instead:

feedback.addPara(T_para1.parameterize(parameters.getParameter("handle","unknown")));

您应该这样做:

String handle=parameters.getParameter("handle","unknown");

  // context=new Context(); // Context exist in a form:

  DSpaceOBject dso = HandleManager.resolveToObject(context,handle);

  if (dso instanceof Item){
       Item item=((Item)dso);
       DCValue[] titles= item.getMetadata("dc", "contributor", "author",null); 

       feedback.addPara(titles[0].value); // check for nulls or multiple values;
  }

要将标题发送到邮件类别，您应该执行以下操作:

to send the title to the mail class you should do:

feedback.addHidden("title").setValue(titles[0].value);

在Aspects/ViewArtifacts/sitemap.xmap中，您应该设置参数:

And at aspects/ViewArtifacts/sitemap.xmap you should set the parameter:

<map:transform type="SolicitarCorreccionForm">
<map:parameter name="title" value="{title}" />
...

获取SendSolicitarCorreccionAction并发送到电子邮件，以将参数添加到邮件中，例如:

Get at SendSolicitarCorreccionAction and send to email, to add the parameters to the mail like:

String title= request.getParameter("title");
email.addArgument(title);    // Titulo
...

您想从

<map:match pattern="solicitarCorreccion/**">

想要的东西.

P.D.-我忘了提起添加SolicitarCorreccionForm的导入:

P.D.- I forget to mention to add imports of SolicitarCorreccionForm:

import org.dspace.content.DCValue;
import org.dspace.content.DSpaceObject;
import org.dspace.content.Item;
import org.dspace.handle.HandleManager;
