将CSS类添加到mail_to ruby​​ on rails helper

Question

I know that you can add HTML classes to link_to helpers like this:

<%= link_to 'Logout', logout_path, class: 'primary-link-style' %>

But what about the mail_to helper? There doesn't seem to be a way to add a HTML/CSS class like you can with the link_to helper.

The docs only talk about examples of inline styling which I want to avoid.

Answer 1

The method signature from the docs you linked to:

 mail_to(email_address, name = nil, html_options = {}, &block) 

That third argument, html_options , works just like the same argument of link_to :

<%= mail_to "foo@example.com", "Email me", class: "primary-link-style" %>
