Can the Admin UI show calculations?

I have two resources; One acting as a course template and one for actualized, planned courses. Both have a price attribute with the intention that if an actualized course does not have a price it will use the default price from its template. This works fine when looking at the result of a read action in iex but the Admin UI doesn't want to show that calculation anywhere. Is this just not part of what AshAdmin is meant to do? This is not really a breaking issue as I will have to write my own dashboard UI on top of this anyway, it would've just been nice to be able to quickly check AshAdmin to see if changes in my resources work as intended.

🤔 do you have public? true on your calculations?

Huh, I didn't even know you could/had to do that. I tried

calculations do
  calculate :price_net, :money do
    public? true

    expr(...)
  end
end

calculations do
  calculate :price_net, :money do
    public? true

    expr(...)
  end
end

and moving public? true into the calculations block but in both cases the compiler gets angry because public? doesn't exist

calculations do
  calculate :price_net, :money do
    public? true

    calculation expr(...)
  end
end

calculations do
  calculate :price_net, :money do
    public? true

    calculation expr(...)
  end
end

it should work

Just tried that and it compiles but the calculation still does not show anywhere in the Admin UI

Huh, that page implies all calculations are included by default. I didn't explicitly overwrite that. Thank you very much for pointing this page out in general though. I was not aware that there is this much control over how AshAdmin handles resources!

Oh, you want table_columns -- nvm

I just tried explicitly telling it to show the calculation and that worked. weird. it shows up as a separate box below the resource itself

ZachDaniel•2mo ago

Yeah Are you looking to edit the show page or the table? They are done differently IIRC

PakoOP•2mo ago

I mainly just wanted to see calculations somewhere so I can quickly check if my calculations work properly instead of having to run the app through iex not sure which message to mark as solution, I think I'll go with the one that has the doc link?
