Module: MasterView::MIO::DefaultGenerateMIOFilter

Included in:
MasterviewController
Defined in:
lib/masterview/io.rb

Overview

checks to see that mv:generate or mv:gen_partial has been used somewhere in file and if not then it puts in a default mv:generate directive based on the following logic. If a body tag exists then add the mv:generate directive to the body tag and also add a mv:omit_tag=“” directive. This is based on the assumption that we are body will be defined in a layout somewhere so we are only interested in the internal content of it (excluding the body tag itself). If a body tag does not exist, then simply add the mv:generate tag to the root element.

Examples: <html><body>Hello world</body></html> becomes <html><body mv:generate=“template_path” mv:omit_tag=“”>Hello world</body></html>

<div>Hello</div> becomes <div mv:generate=“template_path”>Hello</div>
