Overview

A Well is a Receptacle on a Plate, it can contain one or more aliquots. A plate may have multiple wells, with the two most common sizes being 128 (96) and 2426 (384). The wells are differentiated via their Map which corresponds to a row and column. Most well locations are identified by a letter-number combination, eg. A1, H12.

#display_name ⇒ Object

Note:

Be very wary of changing this as we have places in limber (https://github.com/sanger/limber/blob/develop/app/helpers/exports_helper.rb) where it is assumed to contain the barcode and well location. It is highly likely that we aren't the only ones making this assumption.

Returns a name for the well in the format HumanBarcode:Location eg. DN12345S:A1

#poly_metadata ⇒ ActiveRecord::Relation

Returns a collection of PolyMetadatum records associated with the Well. This method overrides the autogenerated poly_metadata method to pick the correct metadatable_type instead of the parent type. Without this override, the generated SQL uses the wrong class name, e.g. Receptacle instead of Well.

Returns:
