Automatically add a class to the body tag
Add a class to your body so that you can easily reference it in your CSS to customize specific pages. You can also add a controller method to add additional classes if needed.
In application_helper:
# Outputs the body classes and adds one that
# is automatically generated
# ex: 'admin-users-index-view'
def body_css_class
@body_css_classes ||= []
view_css_class = [controller_path.split('/'), action_name, 'view'].flatten.join('-')
@body_css_classes.unshift(view_css_class).join(' ')
endNote: You can customize the format easily, remove the 'view' suffix if you don't like it, gsub 'new' and 'edit' for 'form', etc.
In application_controller:
# Controllers can call this to add classes to the body tag
def add_body_css_class(css_class)
@body_css_classes ||= []
@body_css_classes << css_class
endThen in your layout file:
<body class="<%= body_css_class %>">
