[Qgis-developer] Creating a spatialite layer in a python plugin

[Daniel]

Answer:

vlayer = QgsVectorLayer('track.shp', 'layer_name_you_like', 'ogr')

error_msg = ''

error = QgsVectorFileWriter.writeAsVectorFormat( vlayer, 'test.sqlite',
'System', vlayer.crs(), 'SQLite', False, error_msg, [ "SPATIALITE=YES" , ] )

where:

vlayer                             =>  vector layer which will be exported
to spatialite
'test.sqlite'                      =>  absolute path to new spatialite
database file
'System'                         =>  string that represents the file
encoding
vlayer.crs()                      =>  vector layer crs
'SQLite'                           =>  provider name
False                              =>  export onlySelected?
error_msg                        =>  if there is any error message will be
put in that variable (if user don't care about error handling, set to None)
[ "SPATIALITE=YES" , ]   =>  database options. (here is the trick)



Also, there is a class
http://www.qgis.org/api/classQgsVectorLayerImport.html

But, I didn't have success in create an empty database using the
QgsVectorLayerImport. I think that class (QgsVectorLayerImport) expects a
created spatialite database.
