How to read an array of hashes as parameter in ruby on rails?

Question

I wanna read an array of hashes as parameter from postman (or anything else).

postman:

{
  "domains": [
     {"id":"1", "name": "aa"},
     {"id":"2", "name": "bb"}
  ]

}

I need to read this parameter exactly like this:

ruby on rails:

 [
     {"id":"1", "name": "aa"},
     {"id":"2", "name": "bb"}
 ]

How can I do that?

What is context? Is the first codeblock the JSON body (with Content-Type: application/json) of a POST request? If so have you tried accessing it using params[:domains] in the controller? — 3limin4t0r

yes, It is. but with params[:domains], I receive ``` [<ActionController::Parameters {"id"=>"1", "name"=>"aaa"} permitted: false>]```. but I need to read exactly like my question. — user11281772

You can permit your params with this syntax.

params.permit(:domains: %i[id name])
