Add class to erb element

<%= d.box, :class => "something" %>

What is my syntax error here? Can't figure it out. Class is not properly adding to erb variable.

Error message:

syntax error, unexpected =>, expecting :: or '[' or '.' ...pend=( d.box, :class => "something" );@output_buffer.safe... ... ^

<%= %> means just run code and print on view.
so, <%= d.box, :class => "something" %> raise error.

I think you tried call helper method.

You can't add class to a simple value (d.box). ERB will render the value of d.box, let's say 123. So you are trying to add class to 123 which is not a html element. You should add class name to the parent html element.
