Creating a type that accepts a generic map

[bradherman]

The API I'm working with uses Rails on the backend and serializes the errors into a generic map of field_name: [arr_of_messages]... When creating an Error type, I would love to just do the following:

const resp = await makeMyApiCall
if (resp.type === 'errors') {
  return Error.create(resp.data)
}
return OtherModel.create(resp.data

If the payload looks like this:

{
  "data" => {
    "type" => "errors",
    "attributes" => {
        "errors" => {
          "terms_of_service" => ["can't be blank"],
          "email" => ["too short", "must contain @"],
          ...

how can I define my Error model to accept the errors attribute directly knowing the keys in the map will be dynamic?

export const Error = types.model('Error', {
  errors: types.map(...),
})

Hi @bradherman!

You could model it as a map of array of strings:

export const Error = types.model('Error', {
  errors: types.map(types.array(types.string)),
})

will give that a shot... thanks!
