How to add an html id to a form_for tag in rails?

Question

I\'m trying to add an id tag to a form that I\'m creating in rails. The beginning of the form has the following code:

<%= form_for(@user) do |f| %>
         


        

Answer 1

This is new syntax

<%= form_for @user, html: {id: "my_form"} do |f| %> <% end %>

Answer 2

One more way: <%= form_for @user, html: {id: :form_id } do |f| %>

Answer 3

try this <%= form_for @user, :url => "controller action url", :html => {:id => "Blabla"} do |f| %>

EDIT: If you don't want custom action URL then you can use this as well <%= form_for @user, html: {id: "BlaBla"} do |f| %>
