如何將複合式已存在的 address 欄位,轉存到 address_full 欄位

idarfan — Sun, 27 Apr 2014 19:04:49 +0800

我想要把那個 view 裏面地址這個欄位的顯示，轉存到另一個名為 address_full 的欄位去. 我查看了下 view.. 這個部份的程式是這樣寫的

<div class="field1">
  <b>地址:</b>
  <%= area_name(@kojenadult) %><%= @kojenadult.road_name %><%= @kojenadult.address %>
</div>

後來我將它寫到模組中

# encoding: utf-8
class Kojenadult < ActiveRecord::Base 

  before_save :student_id_to_sub_column, :filter_out_xxx_email, :address_to_address_full

protected
  def address_to_address_full
    self.address_full = :area_name(@kojenadult)#@kojenadult.road_name #@kojenadult.address
  end

嗯？噴錯誤了..再幫我看下，這指令要怎麼寫

 SyntaxError in KojenadultsController#search

/home/idarfan/kojenadults/app/models/kojenadult.rb:138: syntax error, unexpected '(', expecting keyword_end
...self.address_full = :area_name(@kojenadult)#@kojenadult.road...

如何避免 adultclasses 輸入學生資料時輸錯或輸入不存在的學生 id

idarfan — Mon, 28 Oct 2013 11:27:08 +0800

撰寫這程式的思維是，adult 是學生資料表 adultclasses 是學生選課資料表，我想要達到的要求是當資料建檔人員鍵入學生選課資料時，要避免輸入不存在於 adult 學生資料表的 student_id. 反覆測了幾次沒能成功

另外我的 rails 版本較為老舊尚未昇級目前為 Rails 3.0.10

由於在建立程式時誤用了複數名稱，因此在 adultclasse.rb 裏做了如下的補救

# encoding: utf-8
class adultClasse < ActiveRecord::Base
set_table_name "adult_classes"
  belongs_to :adult  
  validates :student_id,  :presence =>  {:message => "請您必須填寫學生id"},   
    :length => {:message => "學生id最短4個數字,最長12個數字", :minimum => 4, :maximum => 12}        
end

在 adultclasses_controller.rb 的 cretae 裏做了如下的修改

def create
    @adult_class = AdultClasse.new(params[:adult_classe])
    @adults_session_descriptions = AdultsSessionDescription.all
    if 
      @adult_class = @adult_class.find(:student_id) == Adult.find_by_student_id(:student_id)       
      flash[:notice] = "查無該筆學生id記錄！"
      redirect_to:action => :index       
    else   
         respond_to do |format|
        if @adult_class.save
          format.html { redirect_to(@adult_class, :notice => 'adult classe was successfully created.') }
          format.xml  { render :xml => @adult_class, :status => :created, :location => @adult_class }
        else
          format.html { render :action => "new" }
          format.xml  { render :xml => @adult_class.errors, :status => :unprocessable_entity }
        end
      end
    end

adult.rb 裏的內容

has_many :adult_classe, :dependent => :destroy

關於 options_from_collection_for_select 如何指定預設值的欄位啊? 求賜教

idarfan — Sat, 22 Sep 2012 16:19:31 +0800

Rails 程式在撰寫下拉式選項時：

有一個 id 編號為 9 內容為 "none" 的記錄。

想要把預設指到那兒去，當使用者未留意而按下送出時，至少會送出 none 的記錄。底下的寫法並未能成功做到這樣的功能。有誰有碰到類似的問題？

<div class="field1">
    <%= f.label :adults_license, "5.請輸入認證班課程類別" %><br />
    <%= f.select(:adults_license, options_from_collection_for_select(@adults_licenses,:reason_desc, 'reason_desc', 9), {:prompt => '請選擇課程類別'}) %>  
</div>

上面的程式不能運作啊，怎麼都一直指向 1 去。

Add Behavior to Active Record Associations 要如何在 view 中調用?

idarfan — Mon, 17 Sep 2012 14:08:47 +0800

我碰到一個問題，參考這本書 RailsRecipes 3 關於 Add Behavior to Active Record Associations 如何新增行為到 AR 去。

底下是實行的步驟：

用 scaffold 建立 studnet 模型包括 :name :graduating_year assoc_proxies$ rails g scaffold student name:string graduating_year:integer 用 scaffold 建立 grade 模型包括 :score :class_name assoc_proxies$ rails g scaffold grade score:integer class_name:string

assoc_proxies$ rails c
Loading development environment (Rails 3.0.10)

ruby-1.9.2-p290 :002 > me = Student.create(:name => "idarfan", :graduating_year => 2120)
 => #<Student id: 2, name: "idarfan", graduating_year: 2120, created_at: "2012-09-07 10:52:42", updated_at: "2012-09-07 10:52:42">
ruby-1.9.2-p290 :003 > me.grades.create(:score => 3, :class_name => "Algebra")
 => #<Grade id: 2, student_id: 2, score: 3, class_name: "Algebra", created_at: "2012-09-07 10:53:06", updated_at: "2012-09-07 10:53:06">

ruby-1.9.2-p290 :004 > s_all = Student.all
 => [#<Student id: 1, name: "Chad", graduating_year: 2020, created_at: "2012-09-06 12:23:13", updated_at: "2012-09-06 12:23:13">, #<Student id: 2, name: "idarfan", graduating_year: 2120, created_at: "2012-09-07 10:52:42", updated_at: "2012-09-07 10:52:42">]
ruby-1.9.2-p290 :005 > s_all.each {|s| s.grades}
 => [#<Student id: 1, name: "Chad", graduating_year: 2020, created_at: "2012-09-06 12:23:13", updated_at: "2012-09-06 12:23:13">, #<Student id: 2, name: "idarfan", graduating_year: 2120, created_at: "2012-09-07 10:52:42", updated_at: "2012-09-07 10:52:42">]

ruby-1.9.2-p290 :029 > Student.find(2).grades.below_average
 => []
#改成這樣

ruby-1.9.2-p290 :033 > s_all.each {|s| s.grades.below_average}
 => [#<Student id: 1, name: "Chad", graduating_year: 2020, created_at: "2012-09-06 12:23:13", updated_at: "2012-09-06 12:23:13">, #<Student id: 2, name: "idarfan", graduating_year: 2120, created_at: "2012-09-07 10:52:42", updated_at: "2012-09-07 
10:52:42">]
#看來似乎沒作用
 => [#<Student id: 1, name: "Chad", graduating_year: 2020, created_at: "2012-09-06 12:23:13", updated_at: "2012-09-06 12:23:13">, #<Student id: 2, name: "idarfan", graduating_year: 2120, created_at: "2012-09-07 10:52:42", updated_at: "2012-09-07 10:52:42">]

Student 資料模型中是這樣寫的

class Student < ActiveRecord::Base  
  has_many :grades do
    def below_average
      where('score < ?', 2)
    end
  end
end

grades 資料模型中有個 score 的字段，我要怎麼在 view 中調出這個方法？我只想列出成績小於 2 的。目前僅有兩筆資料。第一筆是 1 第 2 筆是 3.

感謝賜教。

請教如何在 view 產生一個陣列的具體作法？

idarfan — Wed, 02 May 2012 16:17:04 +0800

這個是我 view 的頁面具體的程式碼如下：

<% content_for :header do %>
  <script>
    jQuery(function($){
      //alert("ewe");
      $(".date_pick").datepicker();
    })
  </script>
<% end %>
<form action="show_money" methods="get">
  <input type="text" name="start_at" value="<%= (Time.now - 1.year).strftime("%Y/%m/%d") %>" class="date_pick"/>
  <input type="text" name="end_at" value="<%= Time.now.strftime("%Y/%m/%d") %>" class="date_pick"/>

  <select name="level">
    <% @level.each do |level| %>
      <option value="<%= level[1] %>"><%= level[0] %></option>
    <% end %>
  </select>  
  <select name="howuknowu">
    <% @howuknowu.each do |howuknowu| %>
      <option value="<%= howuknowu[1] %>"><%= howuknowu[0] %></option>
    <% end %>
  </select>
  <select name="whylearn">
    <% @whylearn.each do |whylearn| %>
      <option value="<%= whylearn[1] %>"><%= whylearn[0] %></option>
    <% end %>
  </select>
  <input type="submit" value="send"/>
</form>

我有請教其它的程式設計師，他大概說了底下的作法，說是那樣就可以在 view 產生一個陣列，當參數傳給下一個頁面用。但我無法理解具體的作法該是怎麼樣子

form_tag do
          text_field_tag 'xxx_ids[] x 10'
end

接下來是我控制器裏的寫法 #加入學歷的選項

def money
  @level = Incomelevel.all.map{|im|[im.reason_desc , im.id]}    #test ok by rails c
  @howuknowu = Howuknowu.all.map{|sh|[sh.reason_desc , sh.id]}  #test ok by rails c 
  @whylearn = Whylearn.all.map{|sw|[sw.reason_desc , sw.id]}    #test ok by rails c
  render :layout =>"test_layout"
end

def show_money    
  start_at = Time.parse(params[:start_at])
  end_at = Time.parse(params[:end_at])
  level = params[:level].to_i
  howuknowu = params[:howuknowu].to_i
  whylearn = params[:whylearn].to_i
  @income_ids = params['level[][]'].map{|i|i.to_i > 0 ? i.to_i : nil}.compact
  @howuknowus_ids = params['howuknowu[][]'].map{|i|i.to_i > 0 ? i.to_i : nil}.compact
  @whyulearn_ids = params['Whylearn[][]'].map{|i|i.to_i > 0 ? i.to_i : nil}.compact
  @students = Student.from('students AS s').joins("
  INNER JOIN student_incomes AS si ON si.student_id = s.id AND si.income_id IN (#{@income_ids.join(',')})
  INNER JOIN student_howyouknowus AS sh ON sh.student_id = s.id AND sh.howyouknowus_id IN (#{@howuknowus_ids.join(',')})
  INNER JOIN student_whyyoulearn AS sw ON sw.student_id = s.id AND sw.whyyoulearn_id IN (#{@whyulearn_ids.join(',')})  
  INNER JOIN students ON (students.id = si.student_id AND 
      students.created_at BETWEEN 
      DATE('#{start_at.strftime("%Y/%m/%d")}') AND
      DATE('#{end_at.strftime("%Y/%m/%d")}'))
 ")

執行的話就噴出底下的錯誤訊息，求高手指點

各位路過的大俠大家好：可不可以拔刀相助一下 Orz ... 感謝

我有一個學生表 S 一個學生收入關連表 SI（s.id , si.id) 與學生收入選項表 Income, 及一個從何知道我們的關連表 SH(s.id, sh.id) 與從何知道我們的選項表 Howyouknowus 一個為何學英文的關連表 SW(s.id, sw.id) 與為何學英文的選項表 Whyyoulearn 我想要知道 Income 裏的 row 介於多少價錢之間（income.money) 與 Howyouknous 裏的 row 介於某原因之間（Howyouknous.reason_desc) 及 Whyyoulearn 裏的 row 介於某個原因之間（whyyoulearn.reason_desc) 來選擇出 S 的集合（s.id) 我該如何撰寫合宜的 Active Record 或 Active Record Custom Query? 或如何把底下的 sql 塞進去 models ? 這底下是我想做的 search from 效果示意圖 http://i1210.photobucket.com/albums/cc408/idarfan/_035-1.png 這底是是那段 sql 的截圖 http://i1210.photobucket.com/albums/cc408/idarfan/ohmysql2012-04-25173100.png

汗！這個該死的 Active Record Custom Query 到底要怎麼搞掂它 (我只是想做多個下拉選單的查詢表單)

idarfan — Tue, 24 Apr 2012 14:52:56 +0800

我也試著去把 msyql 的解法給做出來。底下是我寫出來的 mysql ,但這對問題好像沒有幫助因為我也不知道如何將它塞進去 rails 當一個方法用

SELECT  SI.incomelevel_id, SG.graduated_id,  SH.howuknowu_id, SM.mostimportchoice_id, ST.student_id, ST.cname, ST.email
FROM students AS ST, student_incomelevelships AS SI, student_graduatedships AS SG, student_howuknowusships AS SH, student_mostimportchoiceships AS SM
WHERE ST.student_id = SI.student_id  AND  ST.student_id =SG.student_id  AND  ST.student_id = SH.student_id AND ST.student_id= SM.student_id
AND  SI.incomelevel_id = 1
AND  SG.graduated_id =  1
AND  SH.howuknowu_id = 1

GROUP BY ST.student_id

#加入學歷的選項
def money

end

def show_money
    start_at = Time.parse(params[:start_at])
    end_at = Time.parse(params[:end_at])   
    level = params[:level].to_i
    grat = params[:grat].to_i   
    @students = Student.all(:from => "student_incomelevelships AS si AND student_graduatedships AS sg" ,
      :conditions => ["si.incomelevel_id = ? AND sg.graduated_id = ?", level , grat] ,    
      :joins => "INNER JOIN
        students ON students.id = si.student_id AND students ON students.id = sg.student_id AND
        students.created_at BETWEEN DATE('#{start_at.strftime("%Y/%m/%d")}')
        AND DATE('#{end_at.strftime("%Y/%m/%d")}')")   
  end

viewer 的部份是這樣寫的：

<% content_for :header do %>
  <script>
    jQuery(function($){
      //alert("ewe");
      $(".date_pick").datepicker();
    })
  </script>
<% end %>
<form action="show_money" methods="get">

  <select name="level">
    <% @level.each do |level| %>
      <option value="<%= level[1] %>"><%= level[0] %></option>
    <% end %>
  </select>
  <select name="grat">
    <% @grat.each do |grat| %>
      <option value="<%= grat[1] %>"><%= grat[0] %></option>
    <% end %>
  </select>
  <input type="submit" value="send"/>
</form>

joins 的用法部份，我手邊有的資源也相當有限。我比對我 mysql 的語法大致上認為應該沒有錯，只是 AND 與 OR 我目前對其作用不甚明白但這樣我在做查詢時。屢屢出現底下的錯誤訊息 (看起來我的 joins 並沒有用對，能否請您指點我感恩）

sunspot 要如何設定才能令在隨 ubuntu 11.10 伺服器一併起動，不用再去應用程式輸入命令？

idarfan — Fri, 20 Apr 2012 16:52:40 +0800

各位大俠大家好：

看著老外的教程把 sunspot 搭配著 slor 搞了起來，可有件事我很納悶目前我還是跑著 rails 內鍵的伺服器，可是每次我把應用程式跑起來就要再應用程式的目錄下執行下述指令。

rake sunspot:solr:start 有什麼法子該它能隨伺服器一併啟動，懇請賜教

另外我知道在做全文檢索時只能應對一個欄位，我的資料量也不是很多有時想要連 int 的欄位像是 student_id 也想要讓它也一併搜索一下有誰知道這解法嗎？

Squeel 作者網站的示例，怎麼越看越不明白？

idarfan — Thu, 19 Apr 2012 20:36:54 +0800

各位大俠大家好：關於 Squeel 0.95.0 的 joins 真是越參越不明白。。底下是官方的示例 You can refer to these associations when constructing other parts of your query, and they'll be automatically mapped to the proper table or table alias This is most noticeable when using self-referential associations: 構建您的查詢的其他部分時，你可以參考這些關聯，他們將被自動映射到正確的表或表別名，當使用自我參照關聯這是最引人注目的：

Person.joins{children.parent.children}.
       where{
         (children.name.like 'Ernie%') |
         (children.parent.name.like 'Ernie%') |
         (children.parent.children.name.like 'Ernie%')
       }
=> SELECT "people".* FROM "people" 
   INNER JOIN "people" "children_people" ON "children_people"."parent_id" = "people"."id" 
   INNER JOIN "people" "parents_people" ON "parents_people"."id" = "children_people"."parent_id" 
   INNER JOIN "people" "children_people_2" ON "children_people_2"."parent_id" = "parents_people"."id" 
   WHERE ((("children_people"."name" LIKE 'Ernie%' 
         OR "parents_people"."name" LIKE 'Ernie%') 
         OR "children_people_2"."name" LIKE 'Ernie%'))

這段是我照著拿來改改看能不能用的。怎麼改也死活跑不出來真令人納悶有誰能幫我睇下這個惱人的問題感謝

ActiveRecord 關於多個資料表 joins 的問題請教

idarfan — Thu, 19 Apr 2012 16:32:29 +0800

這個是我原先寫在控制器裏的方法，這是以前一個朋友教我的寫法我現在碰到一個難題，除了要列出一定期間內收入為 30000 的學生. 還要列出它是因為工作需要才來選課的學生。請參考底下附圖

def money
    @level = Incomelevel.all.map{|im|[im.reason_desc , im.id]}
    render :layout =>"test_layout"
  end
  def show_money
    start_at = Time.parse(params[:start_at])
    end_at = Time.parse(params[:end_at])
    level = params[:level].to_i    
    @students = Student.all(:from => "student_incomelevelships AS si" , 
      :conditions => ["si.incomelevel_id = ?" , level] ,
      :joins => "INNER JOIN
        students ON students.id = si.student_id AND
        students.created_at BETWEEN DATE('#{start_at.strftime("%Y/%m/%d")}')
        AND DATE('#{end_at.strftime("%Y/%m/%d")}')")    
  end

像這樣的情況，我該如何將其 joins 在一起，並分別列出兩個條件式？懇請賜教

Squeel 的 joins 怎麼用起來那麼不順？

idarfan — Wed, 18 Apr 2012 20:06:56 +0800

各位大俠大家好：

為了方便讓大家明白我的問題，也怕我水平不足無法正確陳述問題。我附上一些圖片但不知會不會被和蟹掉。如果看不到圖請不吝告之那邊有可以正常運作的圖片網站我再去註冊。

Student.joins(:student_incomelevelships => {:incomelevels => :student})

我想把它們 joins 一起再由 view 那兒做出選單大概類似 squeel 範例裏所述的

Person.joins(:articles => {:comments => :person}) => SELECT "people".* FROM people" INNER JOIN "articles" ON "articles"."person_id" = "people"."id" INNER 
JOIN "comments" ON "comments"."article_id" = "articles"."id" INNER JOIN "people" people_comments" ON "people_comments"."id" = "comments"."person_id"

當我用這個指令時

Student.joins(:student_incomelevelships => {:incomelevels => :student})

卻一直出現底下的錯誤訊息

ruby-1.9.2-p290 :018 > Student.joins(:student_incomelevelships => {:incomelevels => :student}) ActiveRecord::ConfigurationError: Association named 'student_incomelevelships' was not found; perhaps you misspelled it?

請問這是什麼原因造成的？還是我指令有錯？

Squeel 0.9.5 的查詢問題請教大家

各位好啊

近日在研究怎麼把 Squeel 0.9.5 怎麼來配合我要做的 search from. 按著說明一個個來測試測到底下的指令就卡住了

我是先在 rails console 底下測。其中有個性別的欄位。它死活就是不讓我過好生納悶，有誰也有在用 Squeel 幫忙看看謝謝 Loading development environment (Rails 3.0.7) ruby-1.9.2-p290 :001 > Student.where{(cname =~ '陳%') & (gender > M) | (cname =~ '陳%') & (gender > F)} NameError: uninitialized constant M from (irb):1:in block in irb_binding' from /home/kojendirect/.rvm/gems/ruby-1.9.2-p290/gems/squeel-0.9.5/lib/squeel/dsl.rb:31:ininstance_eval' from /home/kojendirect/.rvm/gems/ruby-1.9.2-p290/gems/squeel-0.9.5/lib/squeel/dsl.rb:31:in eval' from /home/kojendirect/.rvm/gems/ruby-1.9.2-p290/gems/squeel-0.9.5/lib/squeel/adapters/active_record/3.0/relation_extensions.rb:219:inwhere' from /home/kojendirect/.rvm/gems/ruby-1.9.2-p290/gems/activerecord-3.0.7/lib/active_record/base.rb:442:in where' from (irb):1 from /home/kojendirect/.rvm/gems/ruby-1.9.2-p290/gems/railties-3.0.7/lib/rails/commands/console.rb:44:instart' from /home/kojendirect/.rvm/gems/ruby-1.9.2-p290/gems/railties-3.0.7/lib/rails/commands/console.rb:8:in start' from /home/kojendirect/.rvm/gems/ruby-1.9.2-p290/gems/railties-3.0.7/lib/rails/commands.rb:23:in' from script/rails:6:in require' from script/rails:6:in
