我在动作邮件程序rails 3模型中使用了wicked_pdf pdf_from_string。 pdf渲染完美地做到了这一点:
附件[" pdf.pdf"] = WickedPdf.new.pdf_from_string( render_to_string(:pdf =>" pdf.pdf",:template =>' documents / show.pdf.erb') )
当我尝试传递选项:footer时,它不适用于这些选项:
attachments["pdf.pdf"] = WickedPdf.new.pdf_from_string(
render_to_string(:pdf => "pdf.pdf", :template => 'pdf/pdf.html.erb', :layout => 'pdfs/pdf',
:footer => {:html => {:template => 'pdf/pdf_footer.html.erb', :layout => 'pdfs/pdf'}, :spacing => -65})
)
请注意:页脚选项在控制器内部运行良好,来自控制器默认'渲染' :pdf方法。
我最终做了这样的事情,但我不想使用陷阱。
File.open("/tmp/wicked_pdf_#{@model.number}.html", 'w+b', 0644) { |f|
f.write render_to_string({:template => 'pdf/pdf_footer.html.erb', :layout => 'pdfs/pdf'})
}
attachments["pdf.pdf"] = WickedPdf.new.pdf_from_string(
render_to_string(:pdf => "pdf.pdf", :template => 'pdf/pdf.html.erb', :layout => 'pdfs/pdf'),
:footer => {:html => {:url => "file:///tmp/wicked_pdf_#{@model.number}.html"}, :spacing => -65}
)
有任何线索可以正常工作吗?

这看起来与此问题中的问题有关:
Rails 3 ActionMailer and Wicked_PDF
当您调用渲染时邮件程序不喜欢它。
尝试将附件设置包装在respond_to块中,如下所示:
mail(:subject => 'Your pdf', :to => user.email) do |format|
format.text
format.pdf do
attachments['pdf.pdf'] = WickedPdf.new.pdf_from_string(
render_to_string(
:pdf => "pdf.pdf",
:template => 'pdf/pdf.html.erb',
:layout => 'pdfs/pdf',
:footer => {
:html => {
:template => 'pdf/pdf_footer.html.erb',
:layout => 'pdfs/pdf'
},
:spacing => -65
}
)
end
end
