How to prohibit any response except html in controller

I have such code:

def show
  @attachment = Attachment.find(params[:id])

  respond_to do |format|
    format.html
  end
end

This code allows respond on json, but renders nothing. How to show custom page on any other request except html?

You can restrict the format of your routes when you define them in your config/routes.rb

scope :format => true, :constraints => {:format => :html} do
  resources :attachments
end

Define all the routes whose format you want to restrict within that scope.

Try:

before_filter do
  render text: 'Wrong type', status: 406 unless request.format == Mime::HTML
end

you can use format.any for any other request except html:

def show
  @attachment = Attachment.find(params[:id])

  respond_to do |format|
    format.html { render text: => 'This is html' }
    format.any  { render :text => "Only html is supported" }
  end
end
