Rails/Rspec JSON array of integers being converted to array of strings when testing post call

Question

I have defined param below in my spec file:

let(:params) do
 {
   company: {
    name: "My company",
    company_type_ids: [1,2]
   }
 }
end

There's no problem when I send request with the same param by postman, but when calling post request with rspec array of int in param is converted to string, like this: company_type_ids: ["1", "2"]

It should be company_type_ids: [1,2]

How can I prevent that array in param to be converted to string?

Many thanks!

You can't. The data passed to server via http(s) will always be textual or binary(file upload). Why you need ids as integer? — Amit Patel

@AmitPatel Because I need to handle that integer array before create or update. I have a fixed list of types, and I want to get names of those type ids from list using method "select" and "include?" — Truong Van Cong Nhat

You can still use string ids to search records e.g CompanyType.find(id: params[:company_type_ids]. No need to convert string to integer. — Amit Patel

Actually you can pass integer array as long as you set the header CONTENT_TYPE to be application/json. — moon

How to fix this problem in the post request:

post '/route', params: { 
  array: [1,2] 
}, as: :json
