Notes

When an array parameter is mentioned, the Rails convention of specifying array parameters in query strings is meant. For example, a ruby array like foo = [1, 2, 3] can be encoded in the params as foo[]=1&foo[]=2&foo[]=3. Square brackets can be indexed but can also be empty.

When a file parameter is mentioned, a form-encoded upload is expected.
