"Error: Unable to create PDF!" with WickedPDF
Mistake:
RuntimeError in BillsController#printing
Failed to execute:
"/usr/local/bin/wkhtmltopdf" -q "file:////var/folders/j5/2wx0qdjj7kl7vbvq3m2z4rj00000gn/T/wicked_pdf20130213-41259-x9dcb5.html" "/var/folders/j5/2wx0qdjj7kl7vbvq3m2z4rj00000gn/T/wicked_pdf_generated_file20130213-41259-mg4iqp.pdf"
Error: PDF could not be generated!
BillsController:
# GET /bills
# GET /bills.json
def print
respond_to do |format|
format.html
format.pdf do
render :pdf => "rechnung_id",
:layout => "printing.pdf",
:show_as_html => params[:debug]
end
end
end
as views I created print.html.erb and print.pdf.erb - and tried both.
I installed wkhtmltopdf as binary and as a gem. When I try to use a gem (by commenting out the line:
WickedPdf.config = { :exe_path => '/usr/local/bin/wkhtmltopdf'}
something seems to go wrong and nothing happens. When I use the binary, I get the error displayed at the top. Versions of my gems are wicked_pdf (0.9.4) and wkhtmltopdf-binary (0.9.9.1).
I was looking for help - this is what I already tried:
- "batch update" and "install package"
- installed wkhtmltopdf in version 9.9
- added "Mime :: Type.register" application / pdf ",: pdf"
EDIT: If I use terminal and type "wkhtmltopdf www.myHomepage.info myhomepage.pdf" it works great. "which wkhtmltopdf" gives me the path "/ usr / bin / wkhtmltopdf", but if I want to use it, it will open "wkhtmltopdf_darwin_386" and the site freezes.

now i have solved the problem.
I changed my controller method to:
def printing
@bills = Bill.find(params[:id])
respond_to do |format|
format.html
format.pdf do
render :pdf => "bill_#{@bills.id}",
:wkhtmltopdf => '/usr/bin/wkhtmltopdf',
:template => '/bills/printing.pdf.erb',
:disposition => "inline"
#:save_to_file => Rails.root.join('pdf', "rechnung_#{@bills.id}.pdf")
end
end
end
and I had to remove WickedPDF as middleware in application.rb:
require 'wicked_pdf'
config.middleware.use WickedPdf::Middleware, {}
now it works as expected.
