Wicked_PDF 仅下载 - Rails 3.1

发布于 2024-12-12 07:58:58 字数 757 浏览 2 评论 0原文

我目前运行 Rails 3.1 并使用最新版本的 Wicked_pdf 来生成 PDF。我已经正确设置了所有内容，并且 PDF 生成得很好。

但是，我希望用户能够单击按钮来下载 pdf。目前，当单击时，浏览器会渲染 pdf 并将其显示在页面上。

<%= link_to "Download PDF", { :action => "show", :format => :pdf }, class: 'button nice red large radius', target: '_blank'%>

我的控制器。

def show
    @curric = Curric.find(params[:id])

    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @curric }
      format.pdf do
        render :pdf => @curric.name + " CV",
        :margin => {:top                => 20,  
                    :bottom             => 20 }

      end
    end
  end

我已经被指向 send_file，但完全不知道如何在这种情况下使用它。

任何帮助表示赞赏。

I currently run Rails 3.1 and am using the latest version of Wicked_pdf for PDF generation.
I have set everything up correctly, and PDFs are generated just fine.

However, I want the user to be able to click a button to DOWNLOAD the pdf. At the present time, when clicked, the browser renders the pdf and displays it on the page.

<%= link_to "Download PDF", { :action => "show", :format => :pdf }, class: 'button nice red large radius', target: '_blank'%>

My Controller.

def show
    @curric = Curric.find(params[:id])

    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @curric }
      format.pdf do
        render :pdf => @curric.name + " CV",
        :margin => {:top                => 20,  
                    :bottom             => 20 }

      end
    end
  end

I have been pointed towards send_file, but have absolutely no idea how to use it in this scenario.

Any help is appreciated.

分解您需要设置为“附件”的配置，例如：

respond_to do |format|
  format.pdf do
    render pdf: @curric.name + " CV",
           disposition: 'attachment'
  end
end

Decomposition the config you need to set as 'attachment', example:

respond_to do |format|
  format.pdf do
    render pdf: @curric.name + " CV",
           disposition: 'attachment'
  end
end

我就是这样做的：

  def show
    @candidate = Candidate.find params[:id]

    respond_to do |format|
      format.html
      format.pdf do
        @pdf = render_to_string :pdf => @candidate.cv_filename,
            :encoding => "UTF-8"
        send_data(@pdf, :filename => @candidate.cv_filename,  :type=>"application/pdf")
      end
    end    

  end

它对我有用;-)

I am doing it that way:

  def show
    @candidate = Candidate.find params[:id]

    respond_to do |format|
      format.html
      format.pdf do
        @pdf = render_to_string :pdf => @candidate.cv_filename,
            :encoding => "UTF-8"
        send_data(@pdf, :filename => @candidate.cv_filename,  :type=>"application/pdf")
      end
    end    

  end

and it works for me ;-)

让我们尝试一下：

pdf = render_to_string :pdf => @curric.name + " CV",
                       :margin => {:top     => 20,  
                                   :bottom  => 20 }
send_file pdf

Let's try:

pdf = render_to_string :pdf => @curric.name + " CV",
                       :margin => {:top     => 20,  
                                   :bottom  => 20 }
send_file pdf

//Download pdf generated from html template using wicket_pdf gem 
pdf = render_to_string :template => "simple/show" // here show is a show.pdf.erb inside view

send_data pdf

//Download pdf generated from html template using wicket_pdf gem
