Question

我想更新表，但不执行更新SQL，因此更改无效。

详细说明：

最初是issue.name我们'问题'。我想改成'qqqqqqqqqqqq'。

控制器：

def update
if params['cancel']
  redirect_to(@issue)
  return
end
@issue = Issue.find(params[:id])
logger.debug "original object"
logger.debug "#{@issue.to_yaml}"
logger.debug 'bulk attribute settings...'
@issue.attributes= params[:issue]
logger.debug "after bulk settings"
logger.debug "#{@issue.to_yaml}"

@issue.events.build(:note=>params[:issue][:description],:verb=>'Edited', :changes=>@issue.textalize_changes)

if @issue.save
  logger.debug "after save"
  logger.debug "#{@issue.to_yaml}"
  redirect_to(@issue)
else
  render :action => "edit"
end
end

textalize_changes：

可能有一个额外的代码段

def textalize_changes
r = ""
if changed?
  changes.keys.each do |k|
    r << "#{k.humanize} changed "
    r << "from `#{translate(k,changes[k][0])}` " 
    r << "to `#{translate(k,changes[k][1])}`"
    r << "<br/>"
  end
end
r unless r.blank?
end

结果：

直到行@issue.save一切看起来都正确。我已检查@issue包含我所做的所有更改。
在用户界面上没有我已通知的更改。
在日志中没有更新SQL可见。所有相关的选择和插入都显示但没有更新 - 所以表issues
偶数textalize_changes在检查时没有实现和更改对象（changed?）
如果我在源代码级别手动更改name=XXX的属性，则表明它正在运行。

我根本不知道要检查或检查什么。代码非常简单，根本不知道。

以下是操作的日志：

技术信息：

操作系统：winXP
rails：rails 2.3.4

其他信息：

我有一个正常工作的批量操作。我真的不知道差异：

def update_multiple  
if params['cancel']
  redirect_to issues_path
  return
end
@issues = Issue.find(params[:issue_ids])
@issues.each do |issue|
  issue.attributes= params[:issue].reject {|k,v| v.blank? }
  issue.apply_template_on_name_change
  issue.events.build(:note=>params[:issue][:description],:verb=>"Edited", :changes=>issue.textalize_changes)
  issue.save!
end
flash[:notice]="Issues updated!"
redirect_to issues_path
 end

其他信息：

如果我将@issue.attributes= params[:issue]替换为@issue.attributes= params[:issue].reject {|k,v| v.blank? }，则会应用更改并正常工作。但它不是我真正想要的那个。我想立刻改变一切。我疯了。

Answer 1

您可以尝试使用感叹号进行保存，例如@issue.save!以查看错误。

Answer 2

我在令人敬畏的嵌套集中发现了这个问题。

此插件在执行嵌套集操作之前重新加载对象：我已按以下方式更改控制器：

@issue.parent_issue= params[:issue][:parent_issue]
@issue.attributes= params[:issue].reject {|k,v| 'parent_issue'==k }

这是现在最好的解决方案。

注意：parent_issue用于设置给定实体的父级，并使用与其余属性相同的表单。

不通知属性更改，也不更新表
