邪恶的pdf不呈现页眉/页脚 [英] Wicked pdf not rendering header/footer
问题描述
我正在使用 wicked_pdf 从 html<生成 pdf/code> 在我的 rails 项目中.它正在呈现 template 但我无法打印 header/footer 部分.下面是我的代码，只打印 template 部分
I am using wicked_pdf for generating pdf from html on my rails project. It is rendering template but I could not manage to print header/footer sections. Below is my code that print only template section
render pdf: "pdf_name",
layout: 'application',
template: 'reports/show',
formats: [:html],
margin: { top: 10, bottom: 10, left: 10, right: 10 },
disable_javascript: true,
show_as_html: params[:debug],
header: {
html: { template: 'shared/header' },
spacing: 10
},
footer: {
html: { template: 'shared/footer' },
spacing: 30,
line: true
}
如果我尝试使用 WickedPdf.new.pdf_from_string render_to_string 它显示 Failed to load PDF document 错误即使是简单的 WickedPdf.new.pdf_from_string('<html><body><h1>你好！</h1></body></html>') 不起作用.
If I try to use WickedPdf.new.pdf_from_string render_to_string it show Failed to load PDF document error even simple WickedPdf.new.pdf_from_string('<html><body><h1>Hello There!</h1></body></html>') does not work.
我尝试使用 render_to_string_with_wicked_pdf, render_with_wicked_pdf 但没有成功.我的 Rails 版本是 3.2.19，wicked_pdf gem 版本是 1.1.0 和 wkhtmltopdf 版本是 wkhtmltopdf-0.13.0-alpha-7b36694_linux-trusty-amd64.deb.我也尝试使用 wkhtmltopdf 版本 0.12.0.
I have tried to use render_to_string_with_wicked_pdf, render_with_wicked_pdf but did not success. My Rails version is 3.2.19, wicked_pdf gem version is 1.1.0 and wkhtmltopdf version is wkhtmltopdf-0.13.0-alpha-7b36694_linux-trusty-amd64.deb. I also tried to use wkhtmltopdf version 0.12.0.
我的问题是
- 为什么我的上述实现不起作用?
- 为什么
pdf_from_string不起作用?
- Why my above implementation does not work?
- Why
pdf_from_stringdoes not work?
感谢任何形式的帮助.谢谢.
Any kind of help is appreciated. Thanks.
推荐答案
使用带有补丁的 qt 构建的 wkhtmltopdf 版本，它可以正确地与页脚和页眉配合使用.
Use a version of wkhtmltopdf built with patched qt, which properly works with footer and header.
$ wget http://download.gna.org/wkhtmltopdf/0.12/0.12.4/wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
$ tar xf wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
$ sudo mv wkhtmltox /usr/local/share/
$ sudo update-alternatives --install /usr/local/bin/wkhtmltopdf wkhtmltopdf /usr/local/share/wkhtmltox/bin/wkhtmltopdf 1005
检查版本:
$ wkhtmltopdf --version
应该说:
wkhtmltopdf 0.12.4 (with patched qt)
测试一下:
$ wkhtmltopdf --footer-center 'footer' http://www.google.com google.pdf
你也可以安装 wkhtmltoimage:
you can also install the wkhtmltoimage:
$ sudo update-alternatives --install /usr/local/bin/wkhtmltoimage wkhtmltoimage /usr/local/share/wkhtmltox/bin/wkhtmltoimage 1005
您可以使用这样的脚本:wkhtmltox installer
you can use a script like this: wkhtmltox installer
