[WojciechKo]

Now you can mark attribute that is required in response model.

Hello, i think that should be a part of https://github.com/ruby-grape/grape-swagger-entity

[WojciechKo]

It's not possible because https://github.com/ruby-grape/grape-swagger-entity uses
GrapeSwagger.model_parsers.
With that we can manipulate properties attribute of model definition but we need to add required array to model definition. Like in example:

definitions: {
  Location: {
    type: "object",
    properties: {
      id: { type: "integer" },
      name: { type: "string" }
    },
    required: ["id", "name"],
  },
  ...
}

Ok that sounds reasonable, please fix a tests, write a spec for required attributes, put this pull request to CHAGELOG.md, and add notes to README.md about required attributes
