[GeoREST] Can't update features with PUT

[Pierre-Nicolas Hutin]

Hello,

 

I’ve seen that it is possible to update features through georest. This looks great and very interesting !

 

I’ve tried with the buildings of the Sheybogan MapGuide samples. Currently my data source is a mapguide feature source.

 

I’ve set READONLY to FALSE. I’ve added the PUT method on the XML :

<Representation renderer="XML" pattern=".xml"><Method name="PUT" /><Method name="POST" /><Method name="GET" /></Representation>

 

I’ve modifeied a template in order to be able to update the features as follow :

 

Created a javascript function following the Wiki example :

 

function UpdateFeature()

{

  var xml = '<?xml version="1.0" encoding="UTF-8"?><FeatureSet><Features><Feature>';

  xml = xml+'<Property><Name>NAME</Name><Value>'+document.getElementById('feature_NAME').value+'</Value></Property>';

  xml = xml+'</Feature></Features></FeatureSet>';

                        

  var xmlhttp;

  if (window.XMLHttpRequest)

  {

    xmlhttp=new XMLHttpRequest();

    xmlhttp.onreadystatechange = function(evt)

    {

     if(this.readyState == 4)

     {

        alert(this.responseText);

     }

    };

    xmlhttp.open("PUT",'/rest/data/building/{{BUILDING_ID}}.xml',true);

    xmlhttp.setRequestHeader("Content-Type","application/xml; charset=UTF-8");

    xmlhttp.send(xml);

  }

}

 

And add a simple table with a button :

 

<table width="100%" height="50" id="feature_TABLE" class="mainfont">

               <tr>

                              <th height="10" align="left" valign="left" bgcolor="#E6E6E6" >Edit building data</th>

  </tr>

               <tr>

                              <td class="mainfont" height="10" >

                              <strong ><em>ID: </em></strong><input type="text" name="feature_ID" id="feature_ID" value="{{BUILDING_ID}}" size="17"/></td>

               </tr>

               <tr>

                              <td class="mainfont" height="10" >

                              <strong ><em>Name: </em></strong><input type="text" name="feature_NAME" id="feature_NAME" value="{{BUILDING_NAME}}" size="17"/></td>

                              </td>

               </tr>

               </table>

               <input type="button" name="send" id="button" value="Send" onClick="UpdateFeature()" size="17"/>

{{/BUILDING}}

</td>

</tr>

</table>

 

When cliking on the button send, the following lines are displayed in the Georest server window :

 

PUT(277): http://localhost:99/rest/data/building/15462.xml

Post Data...<?xml version="1.0" encoding="UTF-8"?><FeatureSet><Features><Feature

><Property><Name>NAME</Name><Value>tttttttt</Value></Property></Feature></Featur

es></FeatureSet>...

200(277) Time (0.050005)

 

And a message box is displayed in the webpage : Update Done

 

Though when refreshing the webpage same … I was expecting to see the value I entered in the field . But the field remains balk … any idea .. what is going wrong ?

 

Is this update function of georest reliable ? I was at the end forecasting to do this on a sqlite data source … would it work also ?

 

Thanks for your help,

 

Pierre-Nicolas

Hi guys,

 

Just to notify you that it worked immediately with a feature source pointing to a sqlite file !

Looks great !

 

Don’t know why it didn’t worked with the buildings of Sheybogan …

 

Have a great day !
