You may need to calculate certain page data to generate pagination links. You can use page_data/3 that this module imports for you.

{query, page_data} =
  User

  links = build_links(page_data)
  meta = build_meta(page_data)

def build_filter_query(query, "name", name, _conn) do
  Ecto.Query.where(query, [r], r.name == ^name)
end
