我可以很好地将HTML页面转换为PDF文档.问题是,我不知道如何将HTML文件转换为横向PDF.有没有办法在控制器中设置它？
从控制器......
def pdf_customer_shipments
@customer = Customer.find(params[:id])
@shipments = Shipment.where("customer_id = ? AND status = 'Open'", @customer.id)
render :layout => 'pdf'
end
如果这有帮助,我使用PDFKit并可以使用以下方式渲染PDF格式:
respond_to do |format|
format.html
format.pdf {
html = render_to_string(:layout => false , :action => "my_page.html.haml")
kit = PDFKit.new(html, :orientation => 'Landscape')
kit.stylesheets << "#{Rails.root}/public/stylesheets/views/pdf.css"
send_data(kit.to_pdf, :filename => "some_name.pdf", :type => 'application/pdf')
return # to avoid double render call
}
end
我从这里得到了方向部分:https://github.com/pdfkit/pdfkit/issues/12
您需要在html文件中使用元标记:
...
<head>
<meta name="pdfkit-orientation" content="Landscape"/>
</head>
...
然后PDF是横向的.
PDFKit 应该接受 wkhtmltopdf 的选项，因此您应该能够使用以下命令在横向模式下渲染：
def pdf_customer_shipments
@customer = Customer.find(params[:id])
@shipments = Shipment.where("customer_id = ? AND status = 'Open'", @customer.id
render :layout => 'pdf', :orientation => 'Landscape'
end
