Hi All

Followed the Railcast # 158 on PDF with Prawn

Click the to_pdf link and get the following error message

Hello,

It looks like your model doesn't have eno field.

This is unrelated to Prawn in any way, though.

Hi Alex

Just checked, there is a eno field in the model which is why I am puzzled on the erro message.

What else can I check for ?

TIA

[Alexander Mankuta]

On closer inspection payslips appears to be nil. Check if you've assigned it properly (typos?).

Hi Alexander

I replace # payslips=[payslips.eno, payslips.ename, payslips.dept, payslips.netpay]

with pdf.text="we made it"

Still got an error message
