Ruport官方网站:http://www.rubyreports.org/

本例中将介绍Ruby报表的简单开发

 

开发环境

OS:WindowsXP

Ruby:Ruby1.8.7

Rails:Rails2.3.5

Mysql:Mysql5.0.9

IDE:Rubymine2.0.1

 

一、安装gem

安装命令

gem install ruport

gem install ruport-util

gem install acts_as_reportable

 

二、创建数据库

  database: dbdevelopment
  username: crystal
  password: crystal
  host: localhost

 

三、创建Rails工程RailsRuport

1)配置database.yml,内容如下:

development:
  adapter: mysql
  encoding: utf8
  reconnect: false
  database: dbdevelopment
  pool: 5
  username: crystal
  password: crystal
  host: localhost

 

2)通过scaffold映射Products表

参数为 Product title:string description:string price:integer

 

3)修改routes.rb

修改

map.resources :products

map.resources :products,:collection=>{:save_as_report=>:get}

表示当遇到save_as_report时,用get方式,否则默认方式将跳转到show.html执行查询

 

在最后添加

require "rubygems"

require "ruport"

 

四、修改Product.rb

为Model添加acts_as_reportable方法

修改后代码如下:

class Product < ActiveRecord::Base
  acts_as_reportable
  set_primary_key "product_id"
end

 

五、修改products_controller.rb

1)修改index方法为如下:添加Report的输出应用

def index
    @products = Product.all
    @table = Product.report_table(:all,:only=>['title','description'])
    @grouping = @table.to_group('title')

    respond_to do |format|
      format.html # index.html.erb
      format.xml  { render :xml => @products }
    end
end

 

2)添加save_as_report方法,实现Report的保存应用

def save_as_report
    puts 'Save Pdf!'
    send_data Product.report_table(:all,:only=>['title','description']).to_pdf, :type => "application/pdf",
                             :filename => "books.pdf"

  end

六、 修改app/view/products/index.html.erb

在界面上显示Report绘制的table,在最后添加如下代码:

<h2>Report Table</h2>
<%= @grouping.to_html %>
<br />
<%= link_to 'Save As Report', :controller=>"products",:action=>"save_as_report"%>

演示效果:
