Overview

Edgarj::FormDrawer::Base draws HTML table tag based data entry form. This also provides default methods for SearchFormDrawer search condition entry form.

How to Customize

  1. First, it may be enough to just redefine @options

  2. Next, when draw_ATTR() is defined, it is called. See ModelPermissionControllerHelper for example.

  3. Then, consider to overwrite draw_ATTR() method.

  2. ‘belongs_to’ column uses:

** I18n.t(‘activerecord.attributes.MODEL.EXT_ID’) ** parent.human_name
