ruby on rails - Contact Form (SimpleForm) - Route not found/unable to autoload? -

i'm trying install contact page on ruby on rails app. seems straight forward enough, after installing mailer gems, , creating controller with:

$ rails generate controller contact_form new create

i navigate contact url (/contact_form/new), , says

"unable autoload constant contactformcontroller, expected /home/ubuntu/workspace/app/controllers/contact_form_controller.rb define it"

routes , controller follows:

routes.rb

get 'contact_form/new' 'contact_form/create' resources :contact_forms 

contact_form_controller.rb

class contactformscontroller < applicationcontroller      def new       @contact_form = contactform.new     end      def create       begin         @contact_form = contactform.new(params[:contact_form])         @contact_form.request = request         if @contact_form.deliver           flash.now[:notice] = 'thank message!'         else           render :new         end       rescue scripterror         flash[:error] = 'sorry, message appears spam , not delivered.'       end     end   end 

contact_form.rb

class contactform < mailform::base   attribute :name,      :validate => true   attribute :email,     :validate => /\a([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})\z/i   attribute :message   attribute :nickname,  :captcha  => true    # declare e-mail headers. accepts mail method   # in actionmailer accepts.   def headers     {       :subject => "my contact form",       :to => "your_email@example.org",       :from => %("#{name}" <#{email}>)     }   end end 

note class named contactformscontroller , rails looking contactformcontroller. need pay careful attention pluralization in rails.

• controllers plural.
• models singular.
• routes plural in cases.
• the pluralization of classes must match file name.

so why rails looking contactformcontroller? because routes not defined properly:

get 'contact_form/new' 'contact_form/create' 

get 'contact_forms/new' proper route form create new resource. don't create resources get rid of get 'contact_form/create'.

resources :contact_forms 

is all need.

so fix error should:

1. rename contact_form_controller.rb -> contact_forms_controller.rb.
2. change route definition.
3. request /contact_forms/new instead.
