努力实现对虾栏宝石

Question

I am currently trying this prawn-rails gem. Please note this is not the famous gem 'prawn' .

Following prawn-rails instructions per se (correctly I hope!), so far, I have:

In Users' Controller

  def test 
    @users = User.all
  end

In Users' Index View

<%= link_to "Download PDF", users_test_path(:format=>:pdf) %>

In views/users/test.pdf.prawn

prawn_document do |pdf|
  @users.each {|u| pdf.text u }
end

In routes

get "users/test"

Yet, whenever I attempt to click on the Download PDF link in the user's index, this is what I get:

NoMethodError at /users/test.pdf

undefined method `encode' for #<User:0x007fc6fadb0380>
Did you mean?  encode_with

Any ideas why?

Changed my views/users/test.pdf.prawn to this:

prawn_document do |pdf|

    pdf.font_size 25 
    pdf.text 'List of Users', :style => :bold

  @users.each do |u|  
    pdf.font_size 16
    pdf.text u.first_name + " " + u.last_name
  end

end

And then it showed the results
