# 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.
