Question

New to rails!!!
How do i make my “Send” button call a function (sendmail) which sends an email?
This is what I have so far….
The sendmail in events_controller does not called!
And I have an event in my model, and i am running rails 3.2.3

show.html.erb:

<p><b>Send Results</b></p>
<%= form_tag("/events", :method => "get") do %>
<p><label for="email_recipient">Email recipient</label>:
<%= text_field 'email', 'Email recipient' %></p>
<%= submit_tag "Send" %>
<% end %>

routes.rb:

resources :events do
      member do 
          get '/sendmail', :as => :sendmail
      end
  end

events_controller.rb

   def sendmail
        puts "sendmail"
        Emailer.deliver_results_email
        return if request.xhr?
        render :text => 'Message sent successfully'
  end

emailer.rb

class Emailer < ActionMailer::Base
  #default from: "[e-mail]"
  def results_email
    puts "RESULTS EMAIL"
    #NEVER GETS THIS FAR.....
  end
end

First things first. In your routes.rb you have put the sendmail action inside a member block. This would generate a route like this:

/events/:id/sendmail

If the sendmail action is kindda generic and don’t need to be applied on a single ‘event’, maybe you should put it on a collection block, so your route would be like this:

/events/sendmail

Second, if you run rake routes | grep sendmail in your console, you will get something like this outputed:

sendmail_event GET /events/:id/sendmail events#sendmail

What this line is saying is that you have a route configured and you have a helper route method named sendmail_event_path that you can use to facilitate the understanding of your views, etc. So in your view it would be something like this:

<%= form_tag sendmail_event_path(@event.id) %>
  ...
<% end %>

When you click the submit button the form would be POSTED to the sendmail action of your events_controller.

I suggest you to change your route to a collection, and change to :post, so you can use it without the event isntance.
