# Gone -> If "Yes", set 'gone' to true, then create a Log entry like the following:
# id | loggable_id | loggable_type | logger_id | logger_type | context | start_date | end_date | description | log_action_id | log_action_type | created_at | updated_at
# 18 | 1 | Bike | 4 | User | | 2017-02-03 23:27:00 | 2017-02-03 23:27:00 | Gone | 5 | ActsAsLoggable::BikeAction | 2017-02-03 23:27:36.8387 | 2017-02-03 23:27:36.8387
# See https://github.com/spacemunkay/BikeShed/blob/master/app/components/bike_logs.rb#L12-L18 for example. Use user_id 1 for current_user_id (1 should be the admin ID I think). Use "Date Out" column for start_date & end_date. Set action_id to "COMPLETED".
#
# Date In -> Create a bike log entry with start_date & end_date with same value as "Date In". Set action_id to "AQUIRED"
# Date Out -> Should be the start_date & end_date value for "Gone" column mentioned above.
# Comment -> Create a bike log entry with action_id "NOTE". The log 'description' should be the value of 'Comment'.
