Should solve #177

[sjib]

Relation to Abwasserbauwerk is now empty with SIA405 Export:

Abwasserknoten is still exported.
@urskaufmann Is that what you expect?

Maybe in future ARABauwerk should become part of SIA405 Abwasser.
Do we have to implement the same for the other subclasses that are not part of SIA405 Abwasser (Abflusslose_Toilette and KLARA?)

This would only be needed on tww

[sjib]

For tww this would have to be extended:

    # select all obj_id from wastewater_structure that are not in wwtp_structure
    cursor.execute(
        "SELECT * FROM qgep_od.wastewater_structure WHERE obj_id NOT IN (SELECT obj_id FROM qgep_od.wwtp_structure);"
    )

Abwasserknoten is still exported.

I do not expect, that the node is exported. First of all, I expect that there is no error, when I should export such a database to SIA405.
I think, that wastewater_networkelements without relation to a wastewater_structure should be really exceptions. And VSA / SIA should answer these questions and make changes, if necessary.
I think the same problem will/can occur in model 2020 with e.g. Spuelstutzen or other structure parts, if TWW does not handle this problems.

I have now checked with this new code. And I got the next error (sorry): no more abwassernetzelement, but bauwerksteil:

I did then delete the cover, that was with this ARA-Bauwerk, and then it works....

[urskaufmann]

Does not work, if the ARA-Bauwerk has a structure_part. All Structure_Parts of Wastewater_structures, that are not in the export, can also not be in the export

[sjib]

Thanks for the hint - then I have to adapt this also. Looks a little bit trickier to not export the cover. First work around would be to just leave the fk_abwasserbauerk empty also for Deckel, etc.

[sjib]

• check if ws have to be added also in dss export if selection
• check missing data - comments urs
