Module: SMEditor::Rails::FormHelper

Defined in:
lib/smeditor/rails/form_helper.rb

Overview

View helper that mounts a SMEditor editor inside a Rails form.

<%= form.smeditor_editor :content %>      # via FormBuilder
<%= smeditor_editor(form, :content) %>    # standalone

Emits a hidden field carrying the document HTML plus an empty mount point. The boot script (smeditor.js) finds the mount, attaches a real editor seeded from the hidden field, and writes editor.getHTML() back into that field on every change — so a normal form submit persists the content with no extra wiring.
