Rails 3.2.3想在我的Rails寫了一個「點」系統3應用
我想要一個「點」功能添加到我的Rails應用程序。這個想法非常簡單，如果你點擊UP你的點數將增加1.如果你點擊DOWN你的點數將減少1點。但由於某些原因點數不會改變，並且我創建的每個新鏈接點數會增加10點。
我有個默認爲0在我的移民文件（但他們從來沒有顯示爲零）
t.column :points, :integer, :default => 0`
這裏是我的視圖代碼部分
<td>
<%= link_to "Up",
:url => { :action => 'modify_points',
:id => link.id,
:by => 1 },
:remote => true,
:update => "link" + link.id.to_s %>
</td>
<td>
<%= link_to "Down",
:url => { :action => 'modify_points',
:id => link.id,
:by => -1 },
:remote => true,
:update => "link" + link.id.to_s %>
</td>
<td>
<b> <a href="<%= link.url %>"> <%= link.description %> </a> </b>
(<%= if link.url =~ /:\/\/([^\/]*)/ then $1 else "wrong URL" end %>) <br/>
<span id="link"><%= link.id.to_s %><%= link.points %> </span>
points posted <%= time_ago_in_words link.created_at %> ago
</td>
，這裏是我的modify_points方法在我links_controller.rb：
def modify_points
@link = Link.find(params[:id])
@link.update_attribute :points, @link.points + params[:by].to_i if params[:by] =~ /[+|-]?1/
render_text @link.points
end
現在，我的第一個提交的鏈接有10分，我的第二個環節都有20分，我的第三個環節都有30分...等等....等。 。和UP & DOWN鏈接什麼都不做。爲什麼我看不到0的默認點值？ modify_points方法中的正則表達式代碼是否會導致這些錯誤？
** 編輯：這裏是當按下UP LINK **

這聽起來好像你有多個問題，可能是彼此無關 - 當您創建的鏈接是不使用默認值，而modify_points不按預期工作。您是否可以包含通過單擊其中一個鏈接生成的rails服務器日誌副本？ – MrTheWalrus
只是在按下UP鏈接時添加了服務器日誌 –
