Note* The above codes working perfectly on my windows development environment (ie) PDF generated properly with header and footers. But when i hosted my application in linux production server PDF generated without headers and footers.*

Resolved Header Footer Issue , the above is the working code. The above problem is due to my files don't have enough executable permissions in production Linux environment.

Solution

  • Put .erb at the end of filename

    :header => {:html => { :template=> 'layouts/pdf_header.html.erb'}},
:footer => {:html => { :template=> 'layouts/pdf_footer.html.erb'}}
