#by_location_with_data ⇒ Object

Fetches vendor places and groups route stops by their location object Returns: { location_obj => [route_stop_a, route_stop_b], location_obj_2 => […] } Example: If you have stops for branches in “Bangkok” and “Chiang Mai”,

this returns all stops grouped by their location object

#group_by_sequence ⇒ Object

Groups route stops by their location in sequence order Returns an array of hashes where each hash contains:

- location: the VendorPlace representing the location
- stops: array of route stops at that location, sorted by sequence

Example usage: @stops.group_by_sequence 

location_object_1 => [stop1, stop2, stop3],
location_object_2 => [stop4, stop5]

Stop 0: Location A Stop 1: Location A Stop 2: Location B Stop 3: Location A ← Same location again (For case when the bus has the same origin/destination)
