Update run_external_job to work with updated interface implementation

[amickan]

With the introduction of optional inputs (https://github.com/DIAGNijmegen/rse-roadmap/issues/153), scheduling jobs through the API via the run_external_job helper function will break as soon as people update or add new interfaces to their algorithms.

The run_external_job function currently checks if the provided inputs match those defined on the algorithm.
We need to decide if we want to keep those checks here. The checks already happen on GC, so we could also remove them here, but then again it's good to do some quality checking...

If we want to keep the checks, they will need to be updated to check whether the inputs match any of the possible input sets of the algorithm.

To be able to do that:

• The Algorithm model in gcapi will need to be updated to reflect the move from inputs and outputs to interfaces.
• We'll likely need an AlgorithmInterface model and a AlgorithmInterfaceAPI that map to the new endpoint.

The models are auto extracted. So the Algorithm should reflect the updates already once things are extracted, this includes your newly suggested models.

I do think it wise do some pre-flight checking on the client side. As such, updating those pre-flight checks make sense and should be pretty straight forward.

The models are auto extracted.

Ah nice! I didn't know that. So adding a serializer in GC for the new model is enough for gcapi to pick it up?

[chrisvanrun]

The picking up is still a script that needs to be ran by a developer. But yes =)

[amickan]

Check! I almost thought magic was involved ;-)

But what I meant to clarify is that having a serializer is enough, no need for an API view, right?

[chrisvanrun]

As long as it shows up via the schema it should suffice:

rse-gcapi/generate_models.py

Line 16 in a802507

"https://grand-challenge.org/api/schema/",

thing

I think that if you make the serializer referenced via a field in Algorithm, the new interface model wil show up in the schema.
