When you have a layer with a common ID to e.g. a database/table with numerous entries for this ID you may set up a relation and browse the associated data, but I found no easy way in QGIS so far to also display them on the map/do other stuff with them.</div><div><br></div><div>The only referred way of solving that which I found on the web, is to replicate the geometries for each entry in the database/table.</div><div><br></div><div>But is no convenient way with QGIS to achieve that so far:</div><div>Export WKT of the layer to a new field -> join those attributes to the database/table -> export this as csv -> reimport this dataset with "Add Delimitzed Text Layer", set to WKT.</div><div><br></div><div>This works with points, but when I need to do this with polygons, this approach miserably fails, cause the WKT for even small sized polygons is way too long for a string field, so the WKT is crippled!</div><div><br></div><div>In my specific case which I try to solve for a long time, I receive several point and polygons layers and only one attribute table with a variety of 0 to numerous entries per ID in those layers.</div><div><br></div><div>Even for a small amount of features it is a pain in the ass to produce those "materialized 1:n-relations" for being able to make a map.</div><div>In my despair, I hacked together an external R script doing all the stuff for me, producing all needed layers with one geometry per database/table-entry, but I would like to share this with colleagues without having to install and maintain R at their computers as well.</div><div><br></div><div>In my point of view it would be nice to have a model/python script to do at least the failing stuff:</div><div>Add vector layer, add Table, set Join 1 and 2 -> receive new vector layer with features for each matching entry.</div><div><br></div><div>Shouldn't something like this be quite easy with python?
