<body class='hmmessage'><div dir='ltr'>Ho Dimitris and all,<br><br>the tool you developed it' really fantastic as well as useful from my point of view.<br>Your work made me think about a possible tool: it could be nice to have a query builder for the layer to insert in the map composer, just a sort of a layer pre-filter. Moreover I wonder even if having a combo box, including possible values, in the query builder is easy to implement.<br><br>This my 2 cents.<br>Best<br><br>Eugenio<br><br><hr>Date: Mon, 23 May 2016 17:14:49 +0200<br>From: karakostis.dimitris@gmail.com<br>To: pjdufour.dev@gmail.com<br>Subject: Re: [GeoNode-devel] QueryBuilder for Download Layer functionality<br>CC: geonode-devel@lists.osgeo.org<br><br><div dir=ltr><br><div>Hi guys, </div><div><br></div><div>I have deployed the newly developed 'Query Builder and Map Filter' tool in our staging server for WFP Geonode: <a href="http://staging.geonode.wfp.org/layers/" target=_blank>http://staging.geonode.wfp.org/layers/</a> There are still several features to be added but you can have a look and give some recommendations, improvement ideas etc.</div><div>To use the tool, select a layer, click the Download button and then the Layer Filtering.</div><div><br></div><div>Cheers</div><div>Dimitris</div><div><br></div><div><br></div></div><div class=ecxgmail_extra><br><div class=ecxgmail_quote>On Mon, May 16, 2016 at 9:09 PM, Patrick Dufour <span dir=ltr><<a href="mailto:pjdufour.dev@gmail.com" target=_blank>pjdufour.dev@gmail.com</a>></span> wrote:<br><blockquote class=ecxgmail_quote style="border-left:1px #ccc solid;padding-left:1ex;"><p dir=ltr>Yes, I can help with the GNIP when ready.</p>
<p dir=ltr>The implementation will leverage the cql_filter GeoServer WFS querystring parameter, as such no changes to GeoServer or django DB models are needed.</p>

<br>
Can you file a GNIP for this so we can discuss the implementation as a<br>
group? If you need help with that, let us know. You will need a core<br>
committer to actually file the GNIP. Perhaps Patrick can help?<br>
<br>
Looking forward to seeing/using this!<br>
