RoR form: adding text behind input-field

I am currently working on a registration form. Users should only register with an email-adress belonging to a specific domain (e.g. "@example.com"). I want to add this domain as a text behind the email-input-field to make it clear for the users what to enter. Unfortunately it seems impossible to write something behind an input-field as rails automatically does a line break.
This is the relevant part of the form:

<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
    <%= devise_error_messages! %>
    <div class="field">
        <%= f.label :email %>
        <%= f.text_field :email, autofocus: true %>[@example.com]
    </div>
   
    <div class="actions">
        <%= f.submit "register", class: "button" %>
    </div>
<% end %>

The result should look like [ ] @example.com
Also I need the email-adress to be an actual email-adress. Therefore I also need to manipulate the input e.g. "john" to "[email protected]" before saving the user to the database.

How can I achieve these two things?

The strict answer to your question is that in your controller action you are free to manipulate or set attributes on an instance before you save it.

def create
 @foo = Foo.new(foo_params)
 @foo.email = mangle_email(@foo.email)
 if @foo.save
   ... # normal stuff
 end
end

In your particular case, you should consider the various input scenarios (e.g., user adds the @domain on their own, etc.), since there are lots of cases where just appending something to the end of the user input is probably not what you're after.
