#38 楼 @_samqiu 一眼就被你看出来了，Redmine 你也接触过？^_^

#36 楼 @_samqiu php 我没接触过，所以领会不深，我在一个 view 页面里面的代码头部加了一下你给的语句，报错信息如下：

Started GET "/wktime/edit?project_Id=2&startday=2013-04-21&tab=wktime&user_id=3" for 127.0.0.1 at 2013-07-16 11:34:56 +0800 Processing by WktimeController#edit as HTML Parameters: {"project_Id"=>"2", "startday"=>"2013-04-21", "tab"=>"wktime", "user_id"=>"3"} Current user: xwj (id=5) Rendered plugins/redmine_wktime/app/views/wktime/edit.html.erb within layouts/base (46.9ms) Completed 500 Internal Server Error in 297ms

你给的这句话的添加是不是有讲究的？

#20 楼 @Rei 你昨天发给我的那个 IDE 地址，里面是不是有工具下载，这个工具大么？你手上有么？方便发给我么？

#31 楼 @luikore 谢谢你，照你说的改了^_^

#32 楼 @ery 用 windows 系统是不是就不能用 pry 调试？要把 ruby 学好还要学会用 linux，看来是个大学问。

#28 楼 @luikore 路径下是有几个新生成的文件夹。

是安装的时候，开头出现的那句话 WARNING: Error fetching data: too many connection resets (http://production.s3. rubygems.org/specs.4.8.gz) 还有安装过程中出现的类似语句对整体有影响么？

unable to convert "\x8D" to UTF-8 in conversion from ASCII-8BIT to UTF-8 to GBK for lib/pry-doc/core_docs_18/object_types, skipping unable to convert "\x9A" to UTF-8 in conversion from ASCII-8BIT to UTF-8 to GBK for lib/pry-doc/core_docs_19/object_types, skipping unable to convert "\xED" to UTF-8 in conversion from ASCII-8BIT to UTF-8 to GBK for lib/pry-doc/core_docs_20/object_types, skipping

#23 楼 @luikore 哦，这下明白 heliang7 为啥说远离 windows 了，那是不是也就意味着 pry 不能在 windows 下用？

#22 楼 @hooopo 水平低，所以。。。 看在女流之辈的份上，请多多包涵。

#17 楼 @hooopo 你的意思，我问的一系列问题太菜了？

#13 楼 @blacktulip 谢谢你的帮助，你发的这个链接是怎么安装和使用 pry 的介绍是吧，我在我的机器上用 执行了开头的两个命令，出现这样的信息，是不是表示我机器上还没有 pry？

#15 楼 @heliang7 “远离 windows”？为何？

#3 楼 @Rei 谢谢你，我这里用 chrome 打开你发的这个网站很慢很慢。不知道怎么回事。

#11 楼 @luikore log 目录下有个文件时间是最新的，打开看里面的内容就和我前面贴出来的图上的 cmd 窗口的内容一致。

你说的“插 binding.pry 比 debug 好用”，能在说的详细些么，我还没理解。:$

#4 楼 @heliang7 你帖子上指的控制台 是不是是我现在用来看 puts 结果的地方？

#5 楼 @luikore 看你帖子上说的 $stderr.puts 我试了一下，还是打印不出来，你说的重定向到日志，怎么找这个日志文件？

#1 楼 @chinakr 谢谢你的回复，你给的这个链接，我先收藏先，慢慢学习，对于目前我的水平，这个帖子对我还有点深。 我现在想要的东西是能像一些开发工具那样，能对代码进行单步调试的，因为要修改代码，想用这种调试工具应该要比我现在无头苍蝇般的瞎 puts 好一些。

#29 楼 @zj0713001 收到你的回复，感动 ing，很感谢你在忙碌的工作中这么热心的帮助我，这块东西对于初学的我而言，感觉牵涉的东西纵横交错，有不少想请教的，在这里都贴出来么怕影响版面，所以之前问你是否有其他联系方式，方便进一步请教。

#26 楼 @zj0713001 问个问题，这段代码中 set_project_issues(@xxxx),依你看是做什么用？

set_project_issues(@entries)
   if @entries.blank? && !params[:prev_template].blank?
       @prev_entries = prevTemplate(@user.id)
       if !@prev_entries.blank?
       set_project_issues(@prev_entries)
       @prev_template = true
       end
   end

还有第二个问题，我在之前我贴出来的那个 view 的 erb 文件中看到这段代码，是不是就是引用@prev_template 的地方

<% if !entry.blank? %>
                   <% if !issueWritten %>
                       <% # this is a new Row %>
                       <% # close the previously opened row first %>
                       <%= render :partial => 'edit_hours', :locals => {:entry => nil, :isTemplate => false,
                           :padAt => 'end', :padTill => 8}%>

                       <%= render :partial => 'edit_issues2', :locals => {:entry => entry, :isTemplate => false}%>     
                       <% issueWritten = true %>
                   <% end %>
                   <% # fill the days till the current day %>
                   <%= render :partial => 'edit_hours', :locals => {:entry => nil, :isTemplate => false, 
                           :padAt => 'begin', :padTill => i+1}%>
                   <%= render :partial => 'edit_hours', :locals => {:entry => entry, :isTemplate => false, 
                   :padAt => 'begin', :padTill => i+2}%>   
                   <% thours[i] += entry.hours unless @prev_template%>
                   <% @total_hours += entry.hours unless @prev_template%>
                   <% currencySym = controller.getUnit(entry) %>
               <% end %>
           <% end %>
           <% # write only the firt row for previous week template
             break if @prev_template %>
       <% end %>
   <% end %>

#26 楼 @zj0713001 难关攻破了，我的 ruby 学习之路估计就可以出师了，@zj0713001 ，再帮帮女流一把如何。

#24 楼 @zj0713001 第二个问题，凭我目前的能力还欠缺：（ 首先感谢你这么热心的帮助我，弱弱的问一下，你用聊天工具不？能否求一个，方便我向你进一步请教。

#22 楼 @zj0713001 粗心，没注意_和。的区别，照你说的改了，还是老样子。

#20 楼 @zj0713001 你说“那你的代码里就得写是 @selected_pro.id 而不是 @selected_pro_id”

你的意思是我在 prevTemplate 函数里面 " and project_id=#{@selected_pro_id}"+

这句话应该这样？ " and project_id="+ @selected_pro_id+

#18 楼 @zj0713001 对于第一，我在一个 edit.html.erb 代码里加了这行代码，是不是就能传递参数过去？我查看 edit 页面的源代码，是能得到我要的 project_id 值的。

<%= render :partial => 'row_template' %>
<!--表单头-->
<%= form_tag({:controller => controller.controller_name, :action => 'update'}, :method => :post, :id => 'wktime_edit') do %>

<h2><%= l(:label_wktime) %></h2>
<%=h hidden_field_tag('tab', "#{controller_name}") %>
<!--add project_id Parameter-->
<%=h hidden_field_tag('project_id', "#{@selected_project.id}") %>

<%= render :partial => 'edit_header' %>

对于第二。我还不理解 :$

#14 楼 @Juanito 看到了，谢谢你。之前在运行 ruby 的虚机上的 ie8 看，没有你图上标识的那个<>,用 chrome 浏览就一目了然了。

#13 楼 @lidashuang 谢谢你，用 chrome 看是好多了

@zj0713001 谢谢你的建议，之前我在网上也看了一些相关初级入门文档，因为有代码要改，想边调试边学习，所以也没有很充足的全面学习。对 ruby 这门语言是零基础，先前也不知道好的书和资料哪里有，加上英文不太好，看网上的资源悟性不高吧 :$

**prevTemplate函数**

def prevTemplate(user_id)   
        prev_entries = nil      
        noOfWeek = Setting.plugin_redmine_wktime['wktime_previous_template_week']

        if !noOfWeek.blank?
            entityNames = getEntityNames

**这段是我修改后的sql语句，增加了一个project_id 项目id的结果集删选**

            sqlStr = "select t.* from " + entityNames[1] + " t" + 
                    " inner join (select " + getDateSqlString('spent_on') + " as startday" +
                    " from  " + entityNames[1] + " where user_id = " + user_id.to_s +
                    " group by startday order by startday desc limit " + noOfWeek.to_s + ") as v" +
                    " on " + getDateSqlString('t.spent_on') + " = v.startday where user_id = " + user_id.to_s +

@juanito 你说的 这句话，我没理解 :$,再弱弱的问一下。 你也可以透過點擊頁面的 <> 取得 raw markdown。

@Juanito 谢谢你这么详细的解释，感动 ing... ^_^

@levan 我用 ie8

@juanito，不好意思，对 ruby 这门技术还不太了解，你说的“Markdown 語法幫助”，之前不知道， 在你说回复框后，我看到这行字“按“M”键查看更多 帮助。”

我按 m 没反应，点击“帮助”超链接，弹出来的框是偏移的，文字内容看不完整。
