Princely Plugin: get nil.size error

Hi All,

I want to generate pdf with css. I am using princely plugin.

This is code which I written

def pdf
   prince =
   html_string = render_to_string(:template =>
     :filename => 'some_document.pdf',
     :type => 'application/pdf'

But I am getting error of nil.size

You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.size

RAILS_ROOT: /var/www/sortapp
Application Trace | Framework Trace | Full Trace

app/controllers/users_controller.rb:135:in `pdf'

I also used make_and_send_pdf function but got the same error.
I thought I am getting error in render_to_string function.

Can anyone tell me how can I solve this issues?

Thanks in advance

Did you ever figure out this problem?

I have a working application and my code works on my laptop, but when I
try it on our production server I come up with this error, but for the
life of me I can't figure out why it is being thrown on one machine and
not the other.

NoMethodError: undefined method `size' for nil:NilClass

[RAILS_ROOT]/vendor/plugins/princely/lib/pdf_helper.rb:13:in `render'
[RAILS_ROOT]/app/controllers/driver_payments_controller.rb:13:in `print'

Anyone got any ideas?

This unfortunatly wasn't the problem, but I did manage to figure out I
only got it when running through mod_rails. We just deployed the app to
another server that was rebuilt from scratch and it is working now, so
no idea what the actual cause was.

Thanks for the help.
