Module: CamaContactForm::CoreCompatibility

Defined in:
lib/cama_contact_form/core_compatibility.rb

Overview

camaleon_cms version gate. The plugin needs a core new enough to (a) expose CamaleonCms::UnsafeMarkup (the admin markup gate delegates to it) and (b) not wipe Rails.cache on every frontend POST -- camaleon_cms before 2.9.4 did, through the bundled front_cache plugin, which left the submission throttle counter erased each submission and unable to ever trigger.

The floor is not expressible as a gemspec dependency (camaleon_cms depends on this gem, so a reverse pin would be circular), and older camaleon_cms releases pin cama_contact_form wide enough to resolve this release. So the plugin verifies the version itself, at boot, from the engine initializer -- a seat every process passes through before serving, unlike a controller class body, which under lazy loading may never load before FrontController#save_form is served. It fails fast with an actionable error rather than a broken gate or a silently dead throttle at the first untrusted request.
