我尝试使用wicked_pdf生成pdf,尽管出现错误“无法渲染模板”。我已遵循wicked_pdf指南,但遇到了麻烦。任何帮助表示赞赏。
url:
http://localhost:3000/app/letters/1.pdf
app / controllers / app / letters_controller.rb:
def show
respond_to do |format|
format.html
format.pdf do
render pdf: "Letters" # Excluding ".pdf" extension.
end
end
end
显示页面链接:
<li><a href="<%= app_letter_path(@letter, format: :pdf) %>" target="_blank"> Print</a></li>
app / views / app / letters / show.pdf:
<!doctype html>
<html>
<head>
</head>
<body>
<div>
<p>test</p>
</div>
</body>
</html>
宝石文件:
gem 'wicked_pdf'
gem 'wkhtmltopdf-binary'
错误:
无法加载PDF文档。
答案 0 :(得分:0)
Wicked PDF在此处签出可用选项
views/layouts/pdf.html.erb
中为pdf文档创建布局<!DOCTYPE html> <html> <head> <title>My PDF</title> <%#= wicked_pdf_stylesheet_link_tag "style" -%> </head> <body> <div class='my_container'> <%= yield %> </div> </body> </html>
2-在控制器中(您必须添加选项disposition: 'inline'
才能在新标签页中打开
def show
respond_to do |format|
format.pdf do
render pdf: "show",
disposition: 'inline',
stream: false,
layout: 'layouts/pdf.html.erb'
end
end
end
3-Pdf html文档名称应以.erb
结尾,即app/views/app/letters/show.pdf.erb
<div>
<p>test</p>
</div>
