<div dir="ltr">Finally I found the solution. The function set_rgeo_factory_for_column must be added to each model with a link to PostGIS where you specify which factory you are using. <div><br></div><div>example : set_rgeo_factory_for_column(RGeo::Geographic.simple_mercator_factory.projection_factory)<div>

<div class=""><div dir="ltr">I tried to create the database manually with the template and only after does the migrations. I check the value before being recorded and it is ok (I can obviously unproject the projection). But when it is stored, it cannot be unproject. The problem can come from 2 different points. The activerecord-postgis-adapter/rgeo-activerecord or PostGIS. I think Rails 4 is a possible reason of that.</div>
