Description
With a PostGIS vector layer, providing a bad primary key produces the correct provider.hasErrors() and provider.errors() messages, but the method call returns True despite failing.
Found when developing a Python plugin.
The code involved (table has id primary key, and note varchar()):
feat = QgsFeature() myfields = layer.dataProvider().fields() feat.setFields(myfields) feat.setAttribute("id", None) # The line that causes the failure. None gets translated to 0, which id already exists in table feat.setAttribute("note", "test") feat.setGeometry(QgsGeometry.fromPoint(point)) res = layer.dataProvider().addFeatures([feat]) # addFeature fails, but res == True !!
