Rails button_to does not set the class correctly

Question

My code is:

<%= button_to 'Login', {:type => 'submit', :class => 'submit'} , {}%>

I want to end with this:

<input type='submit' value='submit' class=submit/>

but I get:

<input type=submit value=submit/>

how to set a class?

Answer 1

HTML parameters are the third parameter according to the documentation . Try the following:

<%= button_to 'Login', {}, { :type => 'submit', :class => 'submit' } %>
