The url_for_pagination function throws an error when supplied a nested filter

[theirishpenguin]

The Problem

When I supply a nested filter for an index request - eg. /movies?filter[price][lt]=49
Then I get the error...

Suspected Cause

• The problem appears to be that URI.encode_query/1, which ultimately gets called, does not like nested fields (such as "lt" nested under "price")
• Some efforts to mitigate this already appear to have been taken at

  jsonapi/lib/jsonapi/view.ex

  Line 339 in 52c700d

  |> Utils.List.to_list_of_query_string_components()

  • ... however this mitigation falls short when there are multiple level nested query params
