ruby - Rails: Ajax-enabled form without a model object -

-

i'm new rails , having hard time figuring out how create form submits on ajax without having corresponding model object.

my use case simple form collects email address , sends email; there's nothing persisted, no model.

in cases do have model, i've had success form_for(@model, remote: true). can't seem find right helper case there no model. tried form_tag(named_path, remote: true) , works, not use ajax.

pointers example example proper controller, .html.erb , routes.rb appreciated.

here's how solved it. key using form_tag , specifying hash argument matched route. business logic, need pass in "id" param, used in controller logic.

<%= form_tag(sendmail_path({ id: 1}), remote: true) %>   <%= text_field_tag :email, params[:email] %>   <%= submit_tag "send", remote:true %> <% end %>

routes.rb:

myapp::application.routes.draw   post '/sendmail/:id(.:format)' => 'mycontroller#sendmail', :as => 'sendmail'   # etc... end

i had supply sendemail.js.erb template updates form after submission.
