Hi All,
I want to generate pdf with css. I am using princely plugin.
This is code which I written
def pdf
prince = Prince.new()
html_string = render_to_string(:template =>
'/users/paid_invoice.pdf.erb')
send_data(
prince.pdf_from_string(html_string),
:filename => 'some_document.pdf',
:type => 'application/pdf'
)
end
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
/usr/lib/ruby/gems/1.8/gems/actionpack-2.1.2/lib/action_controller/streaming.rb:123:in
`send_data'
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
