将 pdf 附加到操作邮件程序和邪恶的 pdf 时缺少模板

Question

尝试发送带有pdf附件的电子邮件时出现缺少模板：

控制器

respond_to do |format|
format.html
format.pdf do 
render pdf: "job card ##{@bike_service.id} - #{DateTime.now}", :template => 'bike_services/show.html.erb' # Excluding ".pdf" extension.
end
end
BikeServiceMailer.job_card_pdf_email(BikeService.last.id).deliver_now
end

邮件

def job_card_pdf_email(bike_service_id)
bike_service = BikeService.find(bike_service_id)
attachments["bike_service_#{bike_service.id}-#{DateTime.now}.pdf"] = WickedPdf.new.pdf_from_string(
render_to_string(pdf: 'bike_service', template: File.join('app', 'views', 'bike_services', 'show.pdf.erb'), layout: 'pdf.html')
)
mail(to: todo.owner.email, subject: 'Your job card PDF is attached', bike_service: bike_service)
end

show.pdf.erb 模板已经存在。

我认为您需要将render_to_string行更改为：

render_to_string(pdf: 'bike_service', template: File.join('bike_services', 'show.pdf.erb'), layout: 'pdf.html')

或

render_to_string(pdf: 'bike_service', template: Rails.root.join('app', 'views', 'bike_services', 'show.pdf.erb'), layout: 'pdf.html')

目前，我认为系统正在寻找/Users/vangama/projects/mm-crm/app/views中有效/Users/vangama/projects/mm-crm/app/views/app/views/bike_services/show.pdf.erb不存在的app/views/bike_services/show.pdf.erb。
