Inherits:

• ActionController::Base
• ApplicationController
• BioscanControlLocationsController

Defined in:

app/controllers/bioscan_control_locations_controller.rb

Overview

Handles POST requests to /bioscan_control_locations. This action has been migrated from the Lighthouse /pickings endpoint. The robot uses POST requests to get the locations of the positive and negative controls on the plate with the given barcode.

Request JSON: { “barcode”: “plate_barcode”, “user”: “robot_user”, “robot”: “robot_name” }

Response JSON: { “barcode”: “plate_barcode”, “positive_control”: “well_description”, “negative_control”: “well_description” }

Error responses are returned as: { “errors”: [“error message”] }

The controller validates: - Plate existence - Plate purpose - Plate has samples - Exactly one positive and one negative control

If any validation fails, a JSON error response is returned. Error responses use the same format and HTTP 400 status codes as the original Lighthouse endpoint.
