QGIS : Create a vector layer from a GeoAlchemy2 query

[Marc Martinot]

Hello !

I don't know if I came to the right place but I thought that maybe I can get an answer here...

I'm currently developing a QGIS plugin where I mapped a PostGIS database via GeoAlchemy2.

I wrote a function that returns results from a GeoAlchemy query but have no idea how to create a vector layer from this (by using, for example, a function from QGIS API, like QgsVectorLayer(...)) and display it.

Is there any way to do this ? 

Thanks a lot,

Marc

Hey!

Did you figure this out?

I need to query with GeoAlchemy, transform the result into a QgsVectorLayer so I will be able to run QGIS analysis.

Thanks

Nevermind... 

I'm just using PyQGIS all the way like:

uri = QgsDataSourceURI()
uri.setConnection("localhost", "5432", "geo", "geo", "")
uri.setDataSource("public", "table", "shape_utm", "filter=12")
blocks_layer = QgsVectorLayer(uri.uri(False), "table", "postgres")
