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:

Report Table

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