Is there any way to define additionalProperties? or Free-Form Object

[AlexeyMatskevich]

Hi, I have some rspec test with data:

    let(:data) {
      {
        description: {},
        type: "closed", 
        max_rating: 1,
        answer_options: [
          {id: first_answer_option.id, description: "description", correct: false},
          {id: second_answer_option.id, description: "NOT description", correct: true},
          {description: "New answer", correct: false}
        ]
      }
    }

When generating the documentation, I have this description for the descriopion field

            description:
              type: object
              properties: {}

The description field in my business is a field within which I pass data from the wysiwyg editor, and get an arbitrary object.
I'm trying to define it as a Free Form Object, according to this documentation: https://swagger.io/docs/specification/data-models/data-types/#object
I add this key additionalProperties: {} and remove this key properties: {}

When I run the generation, I get again properties: {} key.

Is there any way to deal with this?

I can try to make a contribution if required.

Right now, this is not doable.
rspec-openapi preserves most of manually added fields (additionalProperties for this case) but resurrect properties.

We may omit properties if there is already additionalProperties manually added.

I guess my example is one of the extreme cases. However, there is another extreme case that may arise for other users.

Instead of a Free object, someone may want to describe a predefined list of fields, but leave the ability to add any set of additional fields.

But in the openapi documentation I couldn't find any direct indication that this is possible, so I don't know if such a complex case actually exists.

Personally, your solution works for me. Just concerned about more general cases.

Implemented in #178
