1.c:\rails flexstore
2.修改数据库配置文件 database.yml
3.c:\flexstore\ruby script/generate model product
4.c:\flexstore\ruby script/generate web_service ProductWervice getall find
5.修改如下两个 rb文件

product_service_api.rb
class ProductServiceApi < ActionWebService::API::Base
  api_method :getall,:returns => [[Product]]
  api_method :find,
  :expects => [{:from=>:int},{:to=>:int}],
  :returns => [[Product]]
end

product_service_controller.rb
class ProductServiceController < ApplicationController
  wsdl_service_name 'ProductService'
  web_service_scaffold :invoke #此处可以像.NET一下直接在浏览器测试web service
  def getall
    return Product.find_all
  end

  def find
    return Product.find(:all,:conditions =>["price >= :from and price <= :to",params])   
   end
end
6. C:\flexstore\ruby script/server

7. http://localhost:3000/Product_Service/service.wsdl

8.测试 http://localhost:3000/Product_Service/invoke

9.使用自己定义的结构
#model
class ReportStruct < ActionWebService::Struct
  member :id, :int
  member :CreateDate,:string
  member :UpdateDate,:string
  member :user_id,:int
  member :Content,:string
  member :username,:string
end

#Controller
def reports_find(userid)
    if userid != 0
      reports = Report.find(:all,:conditions => ["user_id= :userid",params],:order => "CreateDate desc")
    else
      reports = Report.find(:all,:order => "CreateDate desc")
    end
    results = []
    reports.each do |rec|
       results << ReportStruct.new(:id => rec.id, :CreateDate => rec.CreateDate,
           :UpdateDate => rec.UpdateDate, :user_id => rec.user_id,
           :Content => rec.Content,:username => rec.user.DisplayName)
    end
    return results 
  end
