I’m writing terraform custom provider, and I’m completely new at terraform.

I need to take user input, transform it, and pass it to resource, something like this

data "data_source" d1 {
  input = "some input here"
  //output = { param_a,param_b }
}


resource "resource" "r1" {
  input = {
    param_a : data.data_source.output.param_a
    param_b : data.data_source.output.param_b
  }
}

But the problem is that I have many param_x and its very annoying to pass it one by one

Is there any better solution to do that ? Can I pass whole object somehow ?

This unfortunately does not work

resource "resource" "r1" {
  input = data.data_source.output
}
