Overview

Stores a record of which templates have been used in which submission This ensures that a tag clash is not introduced prior to later pooling. We can also enforce uniqueness at the database level, eliminating race conditions when multiple plates get processed at the same time. This is a genuine risk, as the users often process multiple plates in parallel and processing time is non-trivial.

A note on future changes: Once we’ve solved the duplicate-tag-sequences problems it might make sense to actually track tag sequence pairs here, but hopefully by that point we’ll be pooling flexibly anyway. We’d probably also still need to be able to show which templates had been used, as a huge list of oligo sequences isn’t very user friendly.

Instance Attribute Summary

• #enforce_uniqueness ⇒ nil, true

  True to enforce uniqueness of a template within a submission or nil to allow duplicate templates.

Instance Method Summary

• #coerce_false_enforce_uniqueness_to_nil ⇒ Object

  By setting the value to nil, we can bypass the uniqueness constraint on the database.
