如何统计某个页面的用户访问数量 ... 2 replies

yadun — Wed, 20 Aug 2008 17:32:26 +0800

比如我想统计最受欢迎的产品页，最受关注的用户页。
访问一次在数据库里记录一次?如何去除同一会话的对同一页面反复访问及刷新？
需要一个实现简易，效率高的方案。

rails 组合查询 ... no reply

msnvip — Mon, 11 Aug 2008 12:27:32 +0800

实现对数据列表，按动态指定条件查询。跨model

如 school :name string :id integer
,student :name string :id integer
school has_many student,
----------------------------------------
student list 中
单独查询form 可以通过 school 中 name 查询

上面只是举例。写死的方法，可以实现
请教有没有通用的类似hibernate 动态拼接sql之类的
方法，QueryHelper，或插件？

做了一个简单的rails测试应用，ruby script/srever启动之后，第一次访问结果正常，再次刷新就出现model无法找到的name error，请各位大侠指导。谢谢！

错误信息如下：其中Event是我的model class name

Migration貌似不支援unsigned？ ... no reply

CFC — Sat, 02 Aug 2008 17:20:30 +0800

是否Migration不支援unsigned int呢0.0
如果要加入unsigned該不會得自己跑去修表吧？
你們會怎樣處理啊？

rails map.namespace的疑问 ... no reply

pure — Fri, 11 Jul 2008 22:49:51 +0800

我定义了
map.resources :books # 前台

map.namespace :user do |user| #后台管理
user.resources :books
end

的路由,但请求user/books的时候有时候能正常转到user/books控制器,而有时却转到books控制器了,难道在user命名目录下的控制器必须不能同名?

根目录下
class BooksController < ApplicationController

user目录下的
class User::BooksController < ApplicationController

请求user/books时在BooksController 中输出控制器为user/books,但实现渲染的却是books目录下的视图而不是user/books目录下的视图
请求books/时时在BooksController 中输出控制器为books

请有知道的帮忙解释一下原因及解决方案!谢谢!

问题补充：
按理是没问题的,但就是请求一会儿正常一会又不正常,开始怀疑是不是session引起的,后面去掉大部分session问题依旧,就没再找session的原因了.下面是rotues.rb的全部代码:

ActionController::Routing::Routes.draw do |map|
map.root :controller=>'index'
map.resources :users
map.resources :news
map.resources :areas,:collection => { :json => :get,:switch => ost,:convert_code_name => ost }
map.resource :session
map.resources :salons,:member => { :vote => ost,:map => :get },:collection => { :search => :get },:has_many=>[ :comments,:fwus,:flacks,:jobs,:businesses ]

map.namespace :admin do |admin|
admin.root :controller => 'index'
admin.resources :areas
admin.resources :news
end

map.namespace :user do |user|
user.root :controller => 'index'
user.resources :salons,:has_many =>[ :fwus,:flacks,:jobs,:businesses ]
end

map.admin_top '/admin/top', :controller => 'admin/top', :action => 'index'
map.admin_menu_tree '/admin/menu_tree', :controller => 'admin/menu_tree', :action => 'index'
map.admin_main '/admin/main', :controller => 'admin/main', :action => 'index'

map.businesses '/businesses', :controller => 'businesses', :action => 'businesses'
map.user_profile '/user/profile', :controller => 'users', :action => 'edit'
map.signup '/signup', :controller => 'users', :action => 'new'
map.login '/login', :controller => 'sessions', :action => 'new'
map.logout '/logout', :controller => 'sessions', :action => 'destroy'
map.code_image '/code_image', :controller => 'code_image', :action => 'index'

关于ActiveRecord的查询 ... 1 reply

蕲春人 — Fri, 11 Jul 2008 12:13:01 +0800

一. 假设有两张表projects和tasks结构如下：
projects id:integer, name:string
tasks id:integer, name:string, complete:boolean, project_id:integer
两张表为1对多关系，即roject has_many :tasks, 要求写出下列查询：
1. 找出project的name是SourceTheGlobe的所有task
2. 找出有task还没有complete的所有project

3. 找出每个的task都没有complete的所有project

我只会写第一个:

class Task < ActiveRecord::Base
belongs_to roject

def self.find_by_project_name(project_name)
Project.find(:first, :conditions => ["name = ?", project_name] ).tasks
end end

关于routes.rb的奇怪问题 ... 2 replies

sixfooter — Mon, 07 Jul 2008 22:36:36 +0800

我的routes.rb里面有这样一句

map.connect '', :controller => "welcome", :action => 'index'

这个可以让默认的首页指向相应的controller的action
同时我已经设置了welcome的index的cache_page.
在我的电脑上是完全可以的, 可以在public目录下生成index.html静态页面而且再访问也是读取这个页面.

但是网站部署到hostmonster的服务器上就不对了. 每次都生成新的index.html, 而且再访问也不读取相应的cache page了.

到底是什么东西不同了呢?

或者有什么办法让访问一定读取index.html这个缓存页面呢?

<>一书上关于文件上传例子的中以二进制保存文件的问题 ... 1 reply

def picture=(picture_field)
self.name = base_part_of(picture_field.original_filename)
self.content_type = picture_field.content_type.chomp
self.data = picture_field.read
end
这个self.data如果用MYSQL的BLOB类型来存储picture_field.read读出的二进制数据没问题，如果用SQL SERVER2000的image类型来存储就会报错DBI:atabaseError: Not enough SQL parameters，是不是MYSQL的BLOB和MS SQL的image有数据格式不一样，是不是需要做一些转换处理.

关于发送Email的问题 ... 9 replies

Caiwangqin — Tue, 01 Jul 2008 14:51:57 +0800

业务要求需要对用户发送Email, 用户主要使用的Email Service是:

hotmail.com
163.com
126.com
sina.com
qq.com
gmail.com
sohu.com
yahoo.com.cn

使用Ruby on Rails的ActiveMailer能够用SMTP发送出邮件，但自己使用Postfix搭建的SMTP极有可能被各Email服务商屏蔽，而且发送qq.com的Email默认总会在垃圾箱中，迫切需要这个问题。

有没有公司提供保证到达率的SMTP业务呢？Fenng说他们公司是自己搞，不过都在大服务商的白名单里面，我们现在没有这么大业务量的Email怎样做呢？

如何使用最优最简单方法分配？ ... 10 replies

Caiwangqin — Thu, 26 Jun 2008 14:17:53 +0800

现有一表Table1，内容如下：

id name status
1 a 0
2 b 0
. . .
. . .
. . .
90000 n 0

任务是人工检验照片,将status变为1，可以分配n个人同时取其中一条，将status更改为1，如何使用最优最简单的方法分配呢？

有以下思考：

Repeat

Staff = Table1.find(:first, :conditions => "status=0", : order => "id asc")

Staff.update(:status => 1)

以上过程如果有1个人去完成这个任务，没有问题，如果有10个人同时去做，就可能出现抢任务的情况，怎样使用一个简单的方法完成这个任务呢？

注：n不确定，可以3个人做，可以10个人做，所以不考虑使用按id分段的方法。

用mongrel_rails 部署时遇到个问题 ... 6 replies

使用命令：mongrel_rails service::install -N redmine -c D:\dev\NetBeansProjects\redmine\trunk -p 3002 –e production
应该是production 环境，为啥我看系统服务里是这个样子？
"D:/dev/InstantRails/ruby/bin/mongrel_service.exe" single -e development -p 3002 -a 0.0.0.0 -l "log/mongrel.log" -P "log/mongrel.pid" -c "D:/dev/NetBeansProjects/redmine/trunk" -t 0 -r "public" -n 1024

请问这个是什么问题，还需要指定什么参数吗？
