[GeoNode-users] Tip: how to use custom groups in Legend

[Amedeo Fadini]

Hi everybody,

maybe all of you already knows how to setup different groups in the
geoexplorer toc (layercontainer)  for geonode maps...  the default
installations has two groups, "overlay" an "backgrounds".

As long as the gxp.plugins.LayerTre has a property "groups" that is
default setted to null,
(see the file /var/www/geonode/static/geoexplorer/GeoExplorer.js 80302 )

I've found this way to overwrite it and set my custom groups:
 in the map templates dir I've created different templates

/usr/local/lib/python2.7/dist-packages/geonode/maps/templates/maps

map_view.html
map_geoexplorer.js

(original)

map_view_company.html
map_geoexplorer_company.js

(custom)
where  map_view_company.html has only the different script line:

{% include 'maps/map_geoexplorer_company.js' %}


and in map_geoexplorer_company.js the code to load custom groups

<script type="text/javascript">
/* modifica amedeo 27/07/16
 * vengono definiti i layergroup per le mappe di tipo "Abaco"
  */
 gxp.plugins.LayerTree.prototype.groups = {

                "agen": "Agenzie",
                "come":{
                    title: "Commesse",
                    exclusive: true
                                },
                  "comp": "Competitors",
                  "mark": "Commerciali",
                  "default": "Utilità", // title can be
overridden with overlayNodeText
                "background": {
                    title: "Sfondi", // can be overridden with baseNodeText
                    exclusive: true
                }
            };
 </script>


Each group is defined in the form "name": "Title" or can have another
property "exclusive": true for radio button group.

see http://gxp.opengeo.org/master/doc/lib/plugins/LayerTree.html

Now I'm wondering what's the better  way to call differnte templates
based on map name or map id,
I've added a dictionary { "mapid": "templatename"} in
local_settings.py and by now I've customized the
geonode.maps.view.map_view to parse that dictionary, but I'm pretty
sure that the template can be used as an argument of that function so
I can parse the dictionary in geonode.urls.py.


Any comments or suggestions are appreciated.
