Ruby on Rails Form Helpers Create a form
Example
You can create a form using the form_tag helper
<%= form_tag do %>
Form contents
<% end %>
This creates the following HTML
<form accept-charset="UTF-8" action="/" method="post">
<input name="utf8" type="hidden" value="✓" />
<input name="authenticity_token" type="hidden" value="J7CBxfHalt49OSHp27hblqK20c9PgwJ108nDHX/8Cts=" />
Form contents
</form>
This form tag has created a hidden input field. This is necessary, because forms cannot be successfully submitted without it.
The second input field, named authenticity_token adds protection against cross-site request forgery.
