ruby-on-rails-4 – rails 4 wicked pdf缺少模板

我已经使用wicked pdf gem for html to pdf generate in rails 4.它对我不起作用,它会在/events/calendar_month_print.pdf中抛出类似ActionView :: MissingTemplate的错误
缺少模板事件/ calendar_month_print.html.erb,其中包含{：locale => [：en],：formats => [：pdf],：variants => [],：handlers => [：erb,：builder,：raw,： ruby,：rabl,：rxls,：“xls.rxls”,：jbuilder]}.搜索：我也在我的应用程序中创建了calendar_month_print.html.erb文件.我不知道我在哪里丢失.

我的宝石文件

gem 'wicked_pdf'
gem 'wkhtmltopdf-binary'

我的Controller文件

respond_to do |format|
    format.html
    format.pdf do
      render :pdf => "monthly_events.pdf",:template => "events/calendar_month_print.html.erb"
    end
  end

我的视图文件

<%= button_to "Print as pdf",calendar_month_print_events_path(format: "pdf"),:class => "btn btn-primary button monthly_print pull-right",:method => :get,target: '_blank'  %>

我的config / initializers / mime_types.rb

Mime::Type.register "application/pdf",:pdf

我的config / initializers / wicked_pdf.rb

WickedPdf.config = {
#:wkhtmltopdf => '/usr/local/bin/wkhtmltopdf',#:layout => "pdf.html",:exe_path => '/usr/local/bin/wkhtmltopdf'
