I am trying to use a custom font in a pdf I generate from html with PDFKit in my Rails app. I added the font in ...app/assets/fonts/ and included it in my html template:
css:
@font-face {
font-family: 'journal';
src: url(file://#{Rails.root.join('app', 'assets', 'fonts', 'journal.eot')});
src: url(file://#{Rails.root.join('app', 'assets', 'fonts', 'journal.woff')} format("woff")),
url(file://#{Rails.root.join('app', 'assets', 'fonts', 'journal.ttf')}) format("truetype");
}
called it in the css:
h1 {font-family: journal; }

Background
After reading around it seemed to me that Prawn is out and wkhtmltopdf is in. It also seems like the PDFKit and wicked_pdf gems for Rails are the new cool. So I found a screencast by Ryan on how to use PDFKit. I installed everything, tested wkhtmltopdf on the CLI with no problems, fiddled around with Rails settingsto run multiple processes so the asset pipeline works, and all seemed good, except I'm still stuck at the very end of the process (actually getting the PDF response from the server).
Question
When I request a .pdf version of my view (I'm using the PDFKit Middleware option) my browser just sits there waiting for a response, but as soon as I kill the Rails process the PDF I expected to get only then pops up in my browser window. What gives?
What I'm Using
- OS: OSX 10.8.1
- Rails: 3.2.8
- Ruby: 1.9.3
- wkhtmltopdf: 0.11.0_rc1 (although when I run
wkhtmltopdf -V it says 0.10.0_rc2)
- qt: 4.8.2
What I've Done
- used the PDFKit middleware by loading
config.middleware.use "PDFKit::Middleware" in my application.rb file.
- included
gem 'pdfkit' in my Gemfile and installed it with Bundler
- set the
.pdf mime-type in my mime_types.rb initializer with Mime::Type.register_alias "application/pdf", :pdf
- added
config.threadsafe! to config/environments/development.rb for multiple threads so asset pipeline doesn't conflict with PDF engine
- tested
wkhtmltopdf http://www.google.com google.pdf and it generated a PDF of the Google homepage as expected
- tried swapping PDFKit for wicked_pdf and encountered the same problem (hanging, but when Rails process is killed the PDF renders as expected)
What it Looks Like
This is the regular html page rendered by Rails (I've blurred the client details):
This is the CLI output by Rails when I try to navigate to localhost:3000/some/path.pdf. (the app hangs while waiting for a response):
When I finally kill the Rails process with ctrl-c the PDF finally shows up in the browser as I expected to see it (CSS and HTML rendered properly, so assets seem to load fine):
Conclusions So Far
Swapping PDFKit for wicked_pdf and getting the same results seems to make me think the problem isn't with those libraries, but something to do with my development environment. But wkhtmltopdf runs fine off the command line, so that makes me think that it and QT are doing their job. The problem must be in Rails. Maybe I'm not configuring something properly?
Plea for Help
How do I determine what exactly the problem is and how do I fix it?
I'll love you if you can help me <3
Update
I've also tried using an alternative method of rendering the PDF (with .to_pdf) without the middleware option as follows (doing this I commented out config.middleware.use "PDFKit::Middleware" from my application.rb file):
respond_to do |format|
format.html
format.pdf do
html = '<html><body>This is a test.</body></html>'
@pdf = PDFKit.new(html)
send_data @pdf.to_pdf,
:filename => 'whatever.pdf',
:type => 'application/pdf',
:disposition => 'attachment'
end
end

I am generating pdf report from html page with one table.
I am using wkhtmltopdf for the purpose.
when pdf is generated it breaks anywhere in tr tag.
I want to avoid it .

I'm having trouble generating a PDF out of a html page.
I'm using PDFkit. In the process of installing it, I noticed I needed wkhtmltopdf. So I installed it too. I did everything PDFkit's documentation said to do.. and now I'm getting this error when I try to load the PDF.
Here is the error:
command failed: "/usr/local/bin/wkhtmltopdf" "--margin-right" "0.75in" "--page-size" "Letter" "--margin-top" "0.75in" "--margin-bottom" "0.75in" "--encoding" "UTF-8" "--margin-left" "0.75in" "--quiet" "-" "-"
Any idea of what this could be?
Thanks

I am working in a project using ruby on rails(3.1). My requirement is to produce pdf from the html content. So I use pdfkit gem.
In some pages, characters in single line partially cut between pages. When I convert html convert to pdf using pdfkit gem
version of wkhtmltopdf: wkhtmltopdf -- 0.11.0 rc1
operating system: Linux CentOS 5.5
In the image below showing character partially cut between pages.
Please suggest a solution.

I have a rails 3.1 app that creates pdf documents using pdfkit, and everything works as specified, except for the fact that the generated pdfs don't have any styling. I am assuming that wkhtmltopdf doesn't have access to my stylesheets and that it is not a larger issue than that. Would anyone have a clue as to how you would allow access to these stylesheets? I have basically followed railscast #220 on the subject, however I have had to create a new initializer to get pdfkit to work with rails 3.1.
This is the initializer that I had to use to get pdfkit to work with rails 3.1
ActionController::Base.asset_host = Proc.new { |source, request|
if request.env["REQUEST_PATH"].include? ".pdf"
"file://#{Rails.root.join('public')}"
else
"#{request.protocol}#{request.host_with_port}"
end
}
The link to the pdf looks like this:
<%= link_to 'Download PDF', load_path(@load, :format => "pdf") %>
This will give me a link to the pdf that has no styling.
In my application.rb I have configured pdfkit as such:
config.middleware.use PDFKit::Middleware, :print_media_type => true
I have also added this to my layouts/application.html.erb file:
<%= stylesheet_link_tag "application", :media => "all" %>

Ruby 1.8.7, Rails 3.0.4, PDFKit 0.5.0
I'm trying to create a PDF with PDFKit without using the middleware so I can disable javascript (there's an accordion action in there that hides a lot of info that should be on the PDF). However, whenever I try, it fails because it says the partials in my view (show.html.erb) are missing:
Missing partial programs/details with {:locale=>[:en, :en], :formats=>[:pdf], :handlers=>[:erb, :rjs, :builder, :rhtml, :rxml]}
If I remove the references to the partials, it works fine. I've also tried putting the partials in the same directory with show.html.erb to no avail. Here is the code in my controller's show action:
respond_to do |format|
format.html # show.html.erb
format.pdf {
html = render_to_string(:template => "show.html.erb")
kit = PDFKit.new(html, :disable_javascript => true )
send_data(kit.to_pdf, :filename => "test_pdf", :type => "application/pdf", :disposition => 'attachment')
}
end
Is there any way to do this and keep the partials?
EDIT: for now I've done this:
# config/initializers/pdfkit.rb
PDFKit.configure do |config|
config.default_options = {
:page_size => 'Legal',
:print_media_type => true,
:disable_javascript => true
}
end
This has the disadvantage of turning off javascript for every PDF I generate, but it'll do for now. Any answers on the original question of getting the partials to work still with render_to_string still appreciated.

I'm trying to use PDFKit as middleware in a rails 3 app.
I can use wkhtmltopdf from the command line just fine, but my app keeps throwing me this error
command failed: "/Users/bobby/.rvm/gems/ruby-1.9.2-p0/bin/wkhtmltopdf" "--page-size" "Letter" "--margin-top" "0.75in" "--margin-right" "0.75in" "--margin-bottom" "0.75in" "--margin-left" "0.75in" "--encoding" "UTF-8" "--print-media-type" "--quiet" "-" "-"
If i run this in terminal, it waits for my input, so I type some HTML, then press Ctrl-d and it spits what appears to be some PDF... but no luck in rails.
Here's what I have:
application.rb
require File.expand_path('../boot', __FILE__)
require 'rails/all'
require 'pdfkit'
Bundler.require(:default, Rails.env) if defined?(Bundler)
module Mpr
class Application < Rails::Application
YEARS_ARRAY = (2006..2012).map {|y| [y,y]}.unshift(["Year",nil])
MONTHS_ARRAY = (1..12).map{|m| [ Date::MONTHNAMES[m], m]}.unshift(["All months",nil])
config.middleware.use "PDFKit::Middleware", :print_media_type => true
PDFKit.configure do |config|
config.wkhtmltopdf = '/Users/bobby/.rvm/gems/ruby-1.9.2-p0/bin/wkhtmltopdf'
end
end
end
in my controller (first line)
respond_to :html, :pdf
I think I've gone through all threads on SO, Github and Google, but no luck.
Can anyone help or point me in the right direction?
thanks, P.

I am using PDFkit with rails 3.1. In the past I was able to use the render_to_string function and create a pdf from that string. I then add the stylesheets as follows. My issue is that I have no idea how to access them from within the asset pipeline. (This is how I did it in rails 3.0)
html_string = render_to_string(:template => "/faxes/show.html.erb", :layout => 'trade_request')
kit = PDFKit.new(html_string, :page_size => 'Letter')
kit.stylesheets << "#{Rails.root.to_s}/public/stylesheets/trade_request.css"
So my question in how do i get direct access from my controller to my css file through the asset pipline?
I know I can use the Rack Middleware with PDFkit to render the pdf to the browser, but in this case i need to send the pdf off to a third party fax service.
Thanks for your help.

I use pdfkit and wkhtmltopdf to generate pdf documents. When i generate the first pdf all is well. When i quickly (within 5 seconds) generate an other i get the error [Errno 9] Bad file descriptor. If i close the error (step back in browser) and open again, it will create the pdf.
my views.py
config = pdfkit.configuration(wkhtmltopdf='C:/wkhtmltopdf/bin/wkhtmltopdf.exe')
pdfgen = pdfkit.from_url(url, printname, configuration=config)
pdf = open(printname, 'rb')
response = HttpResponse(pdf.read())
response['Content-Type'] = 'application/pdf'
response['Content-disposition'] = 'attachment ; filename =' + filename
pdf.close()
return response
Maybe important note: i run this site on IIS8, when running from commandline (python manage.py runserver) the error is not present.
Any guidelines on how to handle this error would be great.

If somebody is interested in saving the PDF file in the filesystem which is shown by PDFKit middleware gem, then here it is...
- Override the
call method of middleware.rb file.
In overriding just replace this line:
body = PDFKit.new(translate_paths(body, env), @options).to_pdf
with
pdf = PDFKit.new(translate_paths(body, env), @options)
file = pdf.to_file('Your/file/name/path')
Mymodel.my_method() #You can write your method here to use that file
body = pdf.to_pdf #Here you can change the response body
You can also override the response-body and content-type if you don't want to give pdf response. If you have any further query then go ahead.
This procedure is really help full because when you are having heavy JavaScript an CSS in your view file then render_to_string method will not work i.e. it will not render the heavy JavaScript.

I'm trying to create a pdf with PDFKit from a webpage with custom Google Web fonts.
I can't seem to get the custom fonts to work properly.
I'm using the default PDFKit middleware for Rails, as shown here.
Can someone please show me a .html file and the (preferably ruby) code that converts it to a pdf using PDFKit or just wkhtmltopdf. The converted pdf should have pretty fonts :)
