Re: [Qgis-developer] Pyqgis - join a CSV to a vector layer
Martin, Thanks for your answer. Indeed I did not add the layer to the registry in my foreach loop. I did it at the end (for better performance ) Now it is working, thanks a lot !

Re: [Qgis-developer] Pyqgis - join a CSV to a vector layer
Hi Michael your code works for me. Maybe you have not added the loaded DBF to the QgsMapLayerRegistry before using it for the join? The main layer otherwise does not have a way to resolve the reference to layer from its ID. By the way, it is not necessary to set "joinFieldIndex" and "targetFieldIndex" members - they will have no effect.

[Qgis-developer] Pyqgis - join a CSV to a vector layer
Hi all. I am trying to join a DBF to a vector layer via python . I can create the QgsVectorJoinInfo() , set the parameters and add it to the layer : https://pastee.org/fv55y When I get vlayer.vectorJoins() , it is filled (3 times, because I made 3 attempts), but when I open the vector layer properties dialog, no join appears in the Join tab. Should I update something after adding the join via addJoin method ? Has anyone a working example ? Thanks in advance Michael ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
