Subject: [Geoserver-users] App-Schema Custom GetFeatureInfo HTML

Hello,

Having successfully got my App-Schema based WMS to return a PNG image, I now wish to override the GetFeatureInfo request to output custom HTML. I’ve defined the following content.ftl template:

=== Begin content.ftl

<#list features as feature>

${feature.fid}

<#list feature.attributes as attribute>

<#if attribute.name != “the_geom”>

${attribute.name} = ${attribute.value}

</#if>

</#list>

=== End content.ftl

This template gives me the bullet point list I expect to see for the tutorial (non App-Schema) data layers when I invoke a GetFeatureInfo request by clicking on the OpenLayers map, however, when I use the same content.ftl for my App-Schema data layer, the default HTML (a table of attributes instead of my custom bulleted list) is displayed.

Does App-Schema support the use of a custom content.ftl template? If so, what modifications do I need to make to make to the template above in order to display the bulleted list?

Best Regards,

Ryan

As far as I can see, if the feature is a complex one, a different template
is used, complex_content.ftl.

The default one seems to contain this:

<#--
Macro's used for content
-->

<#macro property node>
    <#if !node.isGeometry>
       <#if node.isComplex>
       <td> <@feature node=node.rawValue type=node.type /> </td>
      <#else>
      <td>${node.value?string}</td>
      </#if>
    </#if>
</#macro>

<#macro header typenode>
<caption class="featureInfo">${typenode.name}</caption>
  <tr>
  <th>fid</th>
<#list typenode.attributes as attribute>
  <#if !attribute.isGeometry>
    <#if attribute.prefix == "">
    <th >${attribute.name}</th>
    <#else>
    <th >${attribute.prefix}:${attribute.name}</th>
    </#if>
  </#if>
</#list>
  </tr>
</#macro>

<#macro feature node type>
<table class="featureInfo">
  <@header typenode=type />
  <tr>
  <td>${node.fid}</td>
  <#list node.attributes as attribute>
      <@property node=attribute />
  </#list>
  </tr>
</table>
</#macro>

<#--
Body section of the GetFeatureInfo template, it's provided with one feature
collection, and
will be called multiple times if there are various feature collections
-->
<table class="featureInfo">
<@header typenode=type />

<#assign odd = false>
<#list features as feature>
  <#if odd>
    <tr class="odd">
  <#else>
    <tr>
  </#if>
  <#assign odd = !odd>

  <td>${feature.fid}</td>
  <#list feature.attributes as attribute>
    <@property node=attribute />
  </#list>
  </tr>
</#list>
</table>
<br/>

Hope this helps

Cheers
Andrea

Andrea, you’re a star! I’ve renamed my template from content.ftl to complex_content.ftl and this has worked perfectly – thank you very much

Happy to be of help.
If you have time, could you open a ticket at
http://jira.codehaus.org/browse/GEOS to report the missing bit in the
documentation?
(or if you have even more time, provide a patch for the docs? :-p )

Cheers
Andrea

Hi,

Sorry I just only saw this email. I implemented this.

This is in fact already documented:

http://docs.geoserver.org/latest/en/user/data/app-schema/wms-support.html#getfeatureinfo

Niels
