[Qgis-user] Atlas generation - possibility to display data linked to current atlas feature?

[Alexandre Neto]

Don't know if the join strategy will work. I normally create the view
directly on the postgis DB, and works fine.

According to Nathan, using atlas features fields might be possible in the
future, but I don't think it is available now.
