我有一个用户模型和配置文件模型.
用户has_one：个人资料.
个人资料belongs_to：user.

我的routes.rb看起来像这样：map.resources：users,：has_one => ：简介

当我的应用程序的访问者创建用户并点击提交时,他们将被定向到“创建个人资料”屏幕.

以下控制器创建一个配置文件,以便创建的配置文件URL为：localhost：3000 / users / [user_id] / profile

def new  
    @profile = `current_user.build_profile`  
end

def create
  @profile = current_user.build_profile(params[:profile])
  if @profile.save
    flash[:notice] = 'Profile was successfully created.'
    redirect_to user_profile_path
  else
    flash[:notice] = 'Error.  Something went wrong.'
    render "new"
  end
end

一切正常.

编辑配置文件时出现问题.

起初看起来很好.当我转到“编辑个人资料”视图时,网址是正确的.例如,如果“显示配置文件”视图的URL是localhost：3000 / users / 1 / profile,则“编辑配置文件”视图显示为：localhost：3000 / users / 1 / profile / edit

那很好.

当我进行更改并单击更新按钮时,这似乎也有效.我被引导到正确的“显示配置文件”视图,我得到一个确认更改的闪存通知.

所以这是奇怪的部分.当我回到我的配置文件索引以查看应用程序中的所有配置文件时,结果是每次更新配置文件时应用程序都创建了新的配置文件记录.原始配置文件记录仍然存在,但有新的附加记录.请记住,我的应用中的所有配置文件都与用户绑定,用户只能拥有一个配置文件.因此,如果我的应用程序中有5个用户,那么现在可能有10个不同的配置文件,每个配置文件都有一个指向已打破页面的URL,因为数据库中不存在user_id.例如,localhost：3000 / users / 7 / profile,users / 8 / profile等.

记录将保存到我的数据库中的配置文件表中,但user_id列显示NUL.

我认为问题来自(a)配置文件控制器中的编辑/更新方法,或(b)我用于在配置文件索引页面上显示配置文件的代码.

这是编辑和更新方法的配置文件控制器：

def edit
    @profile = current_user.profile(params[:id])
end

def update
  @profile = current_user.profile.find(params[:id])
  if @profile.update_attributes(params[:profile])
    flash[:notice] = 'Profile was successfully updated.'
    redirect_to(@profile)
  else
    render "edit"
  end

结束

这是配置文件index.html.erb视图文件：

<div id="posts">
  <% @profiles.each do |profile| -%>
    <% unless profile.blank? -%>
    <div class="profiles">
    <div class="right">
            <p><%=h profile.name %></p>
        <p><%=h profile.category %></p>
            </div>
    <div class="bottom">
            <p><%= link_to 'See Profile',user_profile_path(profile) %></p>
            </div>
    <% end -%>
</div>
<% end -%>

重复我的问题：当我编辑个人资料页面时,如何让我的个人资料控制器的编辑/更新方法停止创建新记录？

UPDATE

查看日志,看起来它正在调用Edit方法,但是然后调用“create”方法而不是“update”方法来执行操作.这是我得到的：

我认为这是相关部分,但如果您需要更多,请告诉我.其余的只是个别领域.
