AND status = 'Open'", @customer.id) render :layout => 'pdf' end
def pdf_customer_shipments
@customer = Customer.find(params[:id])
@shipments = Shipment.where("customer_id = ? AND status = 'Open'", @customer.id)

PDFKit应该接受wkhtmltopdf的选项,因此您应该能够使用以下选项以横向模式进行渲染:
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
如果这有帮助,我正在使用PDFKit,可以使用以下方式在横向中渲染pdf:
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
respond|to do |格式|
format.html
格式.pdf{
html=render_to_string(:layout=>false,:action=>“my_page.html.haml”)
kit=PDFKit.new(html,:orientation=>“横向”)
kit.stylesheets“some_name.pdf”,:type=>application/pdf)
返回#以避免双重渲染调用
}
结束
我从这里得到了方向部分:您的html文件中需要一个元标记:
...
<head>
<meta name="pdfkit-orientation" content="Landscape"/>
</head>
...
。。。
...
然后PDF是横向的。这太完美了!在我的中间件初始值设定项中,我需要将默认值保留为纵向,但这允许我逐页覆盖横向。
