answer:If you want to sort the `stations` by `arrival_time` with your given time string format within the SQL query itself, it would be more complex because SQL doesn't understand the `HH:MM am/pm` format directly. You will need to convert the time string into a format that SQL can order properly. One way to do this is to convert the `arrival_time` string to a 24-hour format time string before saving it to the database. This way, when you order by `arrival_time`, SQL can correctly sort it in ascending order. However, if the `arrival_time` is already stored in the database in the given format, you could either: 1. Alter the data within the database to convert the times to a 24-hour format which is easily sortable by SQL. 2. Or, handle the sorting in Ruby after you've retrieved the records, as shown in my original response. If it's not possible to change how the data is stored, and you want to sort the records in Ruby after retrieval, you'll have to fetch all the relevant stations, parse their arrival times to Time objects and then do the sorting. Since you initially highlighted concern over the specific code line for ordering, here's a modified approach with Ruby's sort mechanism: ```ruby class Api::V1::SchedulesController < ApplicationController # .. def index # Your code for getting schedules # .. schedules.each do |schedule| stations = schedule.stations.to_a # Fetch all stations into an array # Sort stations by parsed arrival time using Ruby instead of SQL sorted_stations = stations.sort_by { |station| parse_time(station.arrival_time) } # Your code for checking if both departure and destination stations are on the route # ... trips.each do |trip| trip[:stations] = trip[:stations].sort_by { |station| parse_time(station[:arrivalTime]) } end # Rest of your action... end end private def parse_time(time_str) # Your parsing method... end # ... end ``` In the above code, `.to_a` is used to convert the ActiveRecord Relation object to an array so we can manipulate it in Ruby. Then, we call `.sort_by` with a block that uses the `parse_time` method to sort the stations array by the parsed time objects. Keep in mind that this Ruby-based sorting approach will be less efficient compared to SQL-based sorting, especially with large datasets. For the best performance, consider storing your times in the database in a sortable format.

answer:If you must retain the time in the `HH:MM am/pm` format in the database and need another approach to sorting the times within the query, you could construct a custom SQL CASE statement to transform the AM/PM times into a 24-hour based sorting mechanism. However, this approach may depend on the specific SQL database system you're using and is generally not recommended due to its complexity and database dependency. Instead, I would suggest a server-side sorting approach after retrieving the records. This avoids custom SQL and depends purely on Ruby for the transformation and sorting. Below is how you might accomplish this: ```ruby class Api::V1::SchedulesController < ApplicationController # ... def index departure_station = params[:departure] destination_station = params[:destination] if departure_station.present? && destination_station.present? schedules = Schedule.joins(:stations) .where(stations: { name: departure_station }) .distinct.includes(:stations, route: :bus_schedule) trips = [] # Load the schedules and stations with arrival times schedules.find_each do |schedule| # No longer pre-sorted, as sorting in SQL with time strings is tricky stations = schedule.stations.with_attached_route # Sort stations after fetching from DB sorted_stations = stations.sort_by do |station| parse_time(station.arrival_time) end # ... rest of your processing using sorted_stations end # ... rest of your action end end private # Helper method to parse the string times def parse_time(time_str) time_format = "%I:%M %p" # Adjust the format to match your arrival_time format time = DateTime.strptime(time_str, time_format) # To ensure the sorting happens correctly across day boundaries # we make sure to wrap around times past midnight time = time.change(day: 1, month: 1, year: 2000) end end ``` The `sorted_stations = stations.sort_by { |station| parse_time(station.arrival_time) }` line sorts the `stations` Ruby array based on the 24-hour converted time parsed from the given string format. The `parse_time` method has been adjusted to handle the conversion to a `DateTime` object while forcing all times to a common date. This allows for sorting based on time alone without concern for the actual date. Keep in mind the performance considerations mentioned earlier: The sort operation is in-memory and performs well for small to medium-sized datasets but may not scale well for large datasets. Also, consider standardizing your time formats in the database to a sortable 24-hour time format for future robustness and performance.
