Class Method Details

.resolve(expression, record:, user:) ⇒ Object

Resolves a set_fields value expression to a concrete value.

Supported shapes:

"current_user.id" / "record.title" / "current_date" / "current_datetime"
  → routed through DynamicReferences::Resolver
{ "value" => "literal" }   → string literal
{ "value" => "null" }      → nil
{ "value" => 42 }          → 42
:now / :today (symbol)     → migrated to "current_datetime" / "current_date"
anything else (string, number, true/false, nil) → itself

Legacy hash forms (date:, current_user:, field_ref:) are no longer accepted — callers should use the dotted-string form.
