My api is return a :ok when should be returning a :unprocessable

I have an API that I'm currently using rspec to do the tests. In a specific test, I do a patch/put in a unity giving invalid values, but when I do the same test he responds with a status ":ok" and not a ":unprocessable_entity" as they should.

The test:

it "renders a JSON response with errors for the new unit" do
  post units_url,
  params: { unit: invalid_attributes }, headers: valid_headers, as: :json
  expect(response).to have_http_status(:unprocessable_entity)
  expect(response.content_type).to match(a_string_including("application/vnd.api json"))
end

The update on unit_controller.rb:

def update
  if @unit.update!(unit_params)
    render json: @unit
  else
    render json: @unit.errors, status: :unprocessable_entity
  end
end

The unit_params:

def unit_params
  params.require(:unit).permit(:name)
end

The response:

CodePudding user response：

You need to send such params

{
  "unit": {
    "name": ""
  }
}

You don't need update! method because it raises error if validations fail. Use update (without bang) instead
