在p：dataExporter中更改p：graphicImage的导出值 [英] Change exported value of p:graphicImage in p:dataExporter

问题描述

我有以下问题：

我以0和1字符串形式从数据库中获取虚假/真实值。

因为我想对我的用户很好:-)我的数据表中的输出不应该是零和一个。

所以我使用一个代表状态为零和一个的图形。

我这样做（在p：datatable内）：

 < p：column width =50sortBy =＃{report.arrived}> 
< f：facet name =header> Report？< / f：facet> 
< p：graphicImage library =images
 name =＃{report.arrived} .gif/> 
< / p：column> 
  

所以，0.gif显示为false，而1.gif为true。

看起来像这样：

我从原点的dataexporter的问题是这个列将导出为

org.primefaces.component.graphicimage.GraphicImage@26bbdbd

有没有办法更改导出值？任何想法如何获得图形图像并导出价值？

感谢您的帮助！

p：dataExporter不能识别p：cellEditor

解决方案

根据您真正报告的问题4013 自从PrimeFaces 3.5.25,4.0.9和5.0以来，数据出口商现在对< p：cellEditor> 和< h：图形图像> 。

如果< h：graphicImage> code> alt 属性将用于表示导出的值。额外的好处是，它迫使你使视觉障碍者更容易访问您的网站;）

例如

 < p：graphicImage ... alt =＃{report.arrived =='0'？'否'：'是'}/> 
  

顺便说一下，你应该更好地使用一个布尔值c $ c>或枚举而不是 int 。

另见：

• p：dataExporter不能识别p：cellEditor

I have the following problem:

I get false / true values from my database in form of „0" and „1" strings.

Because I want to be nice :-) to my users, the output in my datatable shouldn't be zeros and ones.

So I use a graphic which represents the states zero and one.

I do it like this (inside p:datatable):

<p:column width="50" sortBy="#{report.arrived}">
           <f:facet name="header">Report?</f:facet>
           <p:graphicImage library="images"
               name="#{report.arrived}.gif" />
</p:column>

So 0.gif is shown for false and 1.gif for true.

It looks like this:

My problem with the dataexporter from primefaces is that this column will be exported as

org.primefaces.component.graphicimage.GraphicImage@26bbdbd

Is there a way to change the exported value? Any ideas how I could get a graphical image and exporting the value?

I appreciate your help!

Solved, smiliar to this solution, thx to BalusC !

p:dataExporter does not recognize p:cellEditor

解决方案

As per issue 4013, reported by yours truly, since PrimeFaces 3.5.25, 4.0.9 and 5.0 the data exporters have now additional support for <p:cellEditor> and <h:graphicImage>.

In case of <h:graphicImage>, the alt attribute will be used to represent the exported value. Additional bonus is, it forces you to make your website more accessible to the visually disabled ;)

E.g.

<p:graphicImage ... alt="#{report.arrived == '0' ? 'No' : 'Yes'}" />

By the way, you should here really better use a boolean or an enum instead of an int.
