Class: ActsAsCalculatorEditor::FormulaVersionsController

Inherits:
ApplicationController show all
Defined in:
app/controllers/acts_as_calculator_editor/formula_versions_controller.rb

Overview

No edit, no update, no destroy — a published version is immutable, and the corrective action is publishing another one (docs/core-gem-contract.md §2.4). new accepts ?from_version_id= so "duplicate this into a new draft" is available, which is usually what an operator reaching for "edit" actually means.

@form and @variable_rows are plain hashes rather than an unsaved FormulaVersion: a failed submission has to come back showing exactly what the operator typed, including the unparseable date that caused the failure, and an ActiveRecord object cannot hold one.

#create ⇒ Object

Straight through PublishFormulaVersion, which is the same object the core gem's own API controller calls: the incumbent is superseded rather than rewritten, version numbers are handed out in one place, and a supersede that would leave part of the incumbent's range with no active version raises PartialSupersedeError — surfaced here as a 409 with its message intact, because that message names the exact date range at issue and the two ways out of it.
