How can I use custom object sets of a specifc object type as input data in my Palantir Foundry Workshop module

Question

I want to provide a Workshop module that can be applied to arbitrary object sets (eg. explorations) that are of a specific object type. The arbitrary object set is defined by the user and somehow provided to the Workshop module when the module is opened. Any functionality inside the module is the applied on this user specified object set. I assume that the user knows the rid of his custom object set (ri.object-set.main.versioned-object-set.UUID) and would be able to provide it.

One way in workshop would be promoted variables. But the documentation stats that this is not possible using promoted variables - I can only use a single object (using its RID) as input (https://www.palantir.com/docs/foundry/workshop/state-saving/#unsupported-promoted-variables-types-in-the-url). The documentation suggests that I can recreate the object set somehow using promoted string vars and using them to filter object sets. From my understanding the workaround is only feasible if the object set has a very small number of filter criteria and the criteria reflect direct values. For me its not an option.

Question: Are there any other ways in workshop to achieve the goal described above. Either with promoted variables or using a different approach?

Answer 1

This might not answer fully your use-case, but you can use routing to have variable defined in the URL of Workshop and so initialize them with a given value.

You will open your Workshop with /workspace/module/view/latest/ri.workshop.main.module.d3e0324a-894f-4f9a-9c65-89cd86ddfb95/page?object-set=ri.object-set.main.object-set.xxx-xxx-xxx-xxx-xxx and this will "set" the value of the object-set variable

Note: This doesn't work with ri.object-set.main.versioned-object-set... but works with ri.object-set.main.object-set...
