Rails How to link an email form with Sendgrid? -

i able create contact form when user clicks submit - send email , receive in inbox. have email sent via sendgrid can analyze analytics. looked @ gorails sendgrid course , able send email via sendgrid don't know how apply contact form. have listed code below, amazing. thank much!

new.html.erb (contact form sends email regularly when user clicks submit)

<div align="center"> <h3>send message us</h3>   <%= form_for @contact |f| %> <div class="field">     <%= f.label :name %><br>     <%= f.text_field :name, :required => true %> </div> <div class="field">     <%= f.label :email %><br>     <%= f.email_field :email, :required => true %>     </div>     <div class="field">     <%= f.label :message %><br>     <%= f.text_area :message, :as => :text, :required => true %>     </div> <div class="actions">     <%= f.submit "send message", :class => "btn btn-primary btn-md"%>     </div>   <% end %> </div> 

contacts_controller.rb

class contactscontroller < applicationcontroller   def new @contact = contact.new   end   def create @contact = contact.new(contact_params)  @contact.request = request if @contact.deliver   flash.now[:notice] = 'thank message. contact soon!' else   flash.now[:error] = 'cannot send message.'   render :new end   end   private   def contact_params   params.require(:contact).permit(:name, :email, :message)   end end 

sendgrid.rb (within config > initializers folder)

actionmailer::base.smtp_settings = {   :user_name => 'apikey',   :password => rails.application.secrets.sendgrid_api_key,   :domain => 'tango.co',   :address => 'smtp.sendgrid.net',   :port => 587,   :authentication => :plain,   :enable_starttls_auto => true } 

development.rb

config.action_mailer.perform_caching = false config.action_mailer.delivery_method = :smtp actionmailer::base.smtp_settings = { :user_name => 'apikey', :password => rails.application.secrets.sendgrid_api_key, :domain => 'tango.co', :address => 'smtp.sendgrid.net', :port => 587, :authentication => :plain, :enable_starttls_auto => true } 

mailers folder (i have 2 files notification , application none deal contacts form)

i figured out missing this. needed generate mailer contacts. completed , adding line contacts_controller.rb, able send emails via sendgrid no problemo :)

class contactscontroller < applicationcontroller   def new @contact = contact.new   end   def create @contact = contact.new(contact_params)  @contact.request = request if @contact.save     contactmailer.new_request(@contact.id).deliver_later end if @contact.deliver   flash.now[:notice] = 'thank message. contact soon!' else   flash.now[:error] = 'cannot send message.'   render :new end   end   private   def contact_params     params.require(:contact).permit(:name, :email, :message)  end end 

contacts mailer

class contactmailer < applicationmailer   def new_request  end end
