Installation

To install this module, you need to have PostGIS installed.

On Ubuntu:

+sudo apt-get install postgis
+

The module also requires two additional python libs:

Shapely
geojson

for a complete documentation please refer to the public documenation

Usage

Important changes in version 11

The geometry attributes must now be explicitly mentioned in the list of fields of +the XML geoengine view definitions. For instance:

+<record id="some_model_geo_view" model="ir.ui.view">
+  <field name="name">Some data view</field>
+  <field name="model">some.model</field>
+  <field name="arch" type="xml">
+    <geoengine>
+      <field name="name" select="1"/>
+      <field name="the_geom"/>
+    </geoengine>
+  </field>
+</record>
+

Known issues / Roadmap

Google layers have been removed as it was not working anyway.
Switching from map to form view should be eased to open selected feature. +It should work using do_switch_view and this probably requires to set self.dataset.index
A good way to open a record from map should be done with double click. +However selection handlers have difficulties to work nice with click events.

Bug Tracker

Bugs are tracked on GitHub Issues. +In case of trouble, please check there if your issue has already been reported. +If you spotted it first, help us smashing it by providing a detailed and welcomed +feedback.

Do not contact contributors directly about support or help with technical issues.
