defmodule Pleroma.User.Query do
@moduledoc """
User query builder module. Builds query from new query or another user query.
## Example:
query = Pleroma.User.Query.build(%{nickname: "nickname"})
another_query = Pleroma.User.Query.build(query, %{email: "email@example.com"})
Pleroma.Repo.all(query)
Pleroma.Repo.all(another_query)
Adding new rules:
- *ilike criteria*
- add field to @ilike_criteria list
- pass non empty string
- e.g. Pleroma.User.Query.build(%{nickname: "nickname"})
- *equal criteria*
- add field to @equal_criteria list
- pass non empty string
- e.g. Pleroma.User.Query.build(%{email: "email@example.com"})
- *contains criteria*
- add field to @containns_criteria list
- pass values list
- e.g. Pleroma.User.Query.build(%{ap_id: ["http://ap_id1", "http://ap_id2"]})
