# frozen_string_literal: true
# Finder for retrieving the pending todos of a user, optionally filtered using
# various fields.
#
# While this finder is a bit more verbose compared to use
# `where(params.slice(...))`, it allows us to decouple the input parameters from
# the actual column names. For example, if we ever decide to use separate
# columns for target types (e.g. `issue_id`, `merge_request_id`, etc), we no
# longer need to change _everything_ that uses this finder. Instead, we just
# change the various `by_*` methods in this finder, without having to touch
# everything that uses it.
class PendingTodosFinder
attr_reader :users, :params
# users - The list of users to retrieve the todos for.
# params - A Hash containing columns and values to use for filtering todos.

@users = users
