Use Arel to run an AND and OR search
set_one_ids = [1,2]
set_two_ids = [3,4]
set_one_query = Thing.where(id: id_set_one).where_values.reduce(:and)
set_two_query = Thing.where(id: id_set_two).where_values.reduce(:and)
Thing.where(set_one.or(set_two))
# That runs the SQL:
# SELECT `things`.* FROM `things` WHERE ((`things`.`id` IN (1, 2) OR `things`.`id` IN (3, 4)))

An example of how you could delete revoked Strava users, along with a primitive retry system
user = User.find(user_id)
begin
client = Strava::Api::V3::Client.new(access_token: user.token)
strava_user = client.retrieve_current_athlete
rescue => error
if error.message.include?('"errors":[{"resource":"Athlete","field":"access_token","code":"invalid"')
user.destroy and return
else
sleep 1

dumbly simple debug output ... Just replace VARIABLENAME with the name (without the $) of the variable (probably an array) you want to see the contents of
// Begin Debug Output
echo "Debug Output for VARIABLENAME:<br><pre>";
var_dump($VARIABLENAME);
echo "</pre><br>End of debug output.";
// End Debug Output
