我想使用Rails 3生成应包含下表的PDF文件。我能够生成PDF文件但无法自定义。
pdftable.html.erb

我想在生成的PDF文件中获取上述文件格式。请检查我的其他以下代码。
table.html.erb
<table class="table table-bordered">

<col class="col-md-1 col-sm-1">
<col class="col-md-3 col-sm-3">
<col class="col-md-2 col-sm-2">

<td class="text-center"><%= @add_payment.total_claim %></td>
<td class="text-center"><i class="fa fa-rupee"></i><%= @add_payment.paid_amount %></td>
<td class="text-center"><i class="fa fa-rupee"></i><%= @outstanding %></td>
<td class="text-center">
<div class="btn-group">

<!-- <a href="javascript:void(0)" title="" class="btn btn-xs btn-success" data-toggle="modal" data-target="#payviewdetailsdiv4">

<i class="fa fa-eye"></i>
<% end %>
</div>
<div class="btn-group">
<a href="javascript:void(0)" title="" class="btn btn-xs btn-danger">
<i class="fa fa-download"></i>

</div>
</td>
</tr>
</tbody>
</table>
控制器/ payment_controller.rb：
class PaymentsController < ApplicationController
require "prawn/table"
require "prawn"
def download_pdf
@product = Product.all
respond_to do |format|
format.pdf do
pdf = Prawn::Document.new
table_data = Array.new
table_data << ["Sl no", "Receipt No","Item","Amount"]
@product.each do |p|
table_data << [p.id, p.Receipt_no,p.item,p.Amount]
end
pdf.table(table_data, :width => 500, :cell_style => { :inline_format => true })
send_data pdf.render, filename: 'test.pdf', type: 'application/pdf',:disposition => 'inline'
end
end
end
end
我正在使用两个gem，即gem 'prawn', '~> 1.3.0'和gem 'prawn-table', '~> 0.2.1'来生成PDF文件。这里我的要求是我需要PDF文件，但是这个文件中的表格格式应该按照我的第一个代码显示（即pdftable.html.erb）。请帮我用Rails 3添加这种类型的布局。
答案 0 :(得分：0)
def download_pdf
@product = Product.all
end
创建名为download_pdf.pdf.prawn的文件 在该文件中，您可以使用prawn gem构建表 http://prawnpdf.org/manual.pdf
