I'm trying to follow this tutorial.
When I'm adding .pdf to my url it does nothing. My controller has:
respond_to :html, :pdf.
My mime type has been declared.
I tried this too:
respond_to do |format|
format.html
format.pdf {
html = render_to_string(:layout => false , :action => "www.google.fr")
kit = PDFKit.new(html)
send_data(kit.to_pdf, :filename => "candidats.pdf", :type => 'application/pdf')
return # to avoid double render call
}
end
but it does not work and I don't get errors. My browser keep waiting for localhost, but nothing happens.
So how should I try to use pdfkit ?
edit 2 :
According to my rails' logs, rails render successfully the HTML. I saw this in the .log, rails doesn't send it to webrick nor to my browser. And my browser keeps waiting, and waiting and nothing happen. I only have little pictures here.
edit 3 : My webrick server seem unable to respond to other request, once he starts getting a .pdf version of my url, any ideas ?
edit 4 :
I am using rails 3.1, wkhtmltopdf 0.9.5 (windows installer) and pdfkit 0.5.2
I found a better way to access my .pdf urls even in developpement mode.
# Enable threaded mode
config.threadsafe!
# Code is not reloaded between requests
#config.cache_classes = true
Config.cache_classes is a comment, cause i had some problems when it wasn't. This way pdfkit works wonder even with rails 3.1. But, you don't reload code between requests.
That's not really a problem, cause you first work on your html, and you switch configuration, in order to check the pdf result. This way you don't have to bother about your production database.
Thanks to another stack overflow answer I got part of solution.
This works:
html = '<html><body>Toto de combats</body></html>'
@pdf = PDFKit.new(html)
send_data @pdf.to_pdf, :filename => "whatever.pdf",
:type => "application/pdf",
:disposition => "attachement"
You can replace attachement by inline, so the pdf is displayed in your browser.
In the stack overflow answer I spoke about (I don't remember the link), the .to_pdf was missing, but is mandatory. Otherwise PDF reader doesn't recognize it.
I'm trying to get this work with a .pdf url.
Edit 3:
My problem with .pdf urls is solved. known issue with rails 3.1, but google was unable to find them.
