Adding a custom class for form_for in Ruby on rails [duplicate]

Question

I am trying out development on Ruby on Rails and I am creating a form using form_for helper:

 <%= form_for(:session, url: login_path) , :html => {:class => "formsignin"} do |f| %>

I am trying to add my own custom class formsignin but this does not work.

Does this answer your question? Use Rails’ form_for but set custom classes, attributes on <form> element? — Nikhil Wagh

:html option is an argument to form_for helper, you've closed form_for method call too early! Reference documentation for form_for.

Try the following:

<%= form_for(:session, url: login_path, html: {class: "formsignin"}) do |f| %>
