PDFKit not generating correct PDF
I installed PDFKit and wkhtmltopdf.
In one action I render a simple html like:
<html><body><h1>Hello Internet!</h1></body></html>
When I run my action with .pdf extension it generates a wrong pdf file. Debugging PDFKit I got to these lines:
result = IO.popen(invoke, "w+") do |pdf|
pdf.puts(@source.to_s) if @source.html?
pdf.close_write
pdf.gets(nil)
end
Well, this is where my PDF is generated, it uses a command line no wkhtmltopdf and my html as input.
Using rdebug I found that the value for invoke is:
"c:\Program Files\wkhtmltopdf\wkhtmltopdf.exe" "--margin-right" "0.75in" "--page-size" "Letter" "--margin-top" "0.75in" "--margin-bottom" "0.75in" "--encoding" "UTF-8" "--margin-left" "0.75in" "--quiet" "-" "-"
And @source.to_s is
<html><body><h1>Hello Internet!</h1></body></html>
Ok, so I tried to run the command by hand like this:
"c:\Program Files\wkhtmltopdf\wkhtmltopdf.exe" "--margin-right" "0.75in" "--page-size" "Letter" "--margin-top" "0.75in" "--margin-bottom" "0.75in" "--encoding" "UTF-8" "--margin-left" "0.75in" "--quiet" "-" "-" < c:\hello_internet.html > correct.pdf
Obviously in hello_internet there is the content of @source.to_s
Running it results in the correct pdf being generated.
The correct pdf generated is here and the wrong is here.
I have no idea what can be wron开发者_高级运维g here.
Thanks.
The solution is pretty simple and is object of a pull request by bxu689 at PDFKits Github.
