I would like to join a CSV and a vector layer, based on a field.
I know I can handle this with multiple lines like in first part of https://www.qgistutorials.com/en/docs/performing_table_joins_pyqgis.html .
However, in order to get things a bit shorter and clearer, I would like to use processing algorithm "qgis:joinattributestable".
processing.runandload('qgis:joinattributestable', shp, csv, shpField, csvField, None) would be the solution.
Now I'm under Qgis 3.8, I know I can use
My question then is : what are the keys of the values (shp, csv, shpField, csvField) that I have to feed
parameters dictionnary with ? And also where can I fin this information next time ? (https://docs.qgis.org/testing/en/docs/user_manual/processing_algs/qgis/vectorgeneral.html#join-attributes-by-field-value does not tell it if I'm right).
