rails嵌套窗体问题

我试图让一个嵌套窗体显示空字段（当前存在的数据正在显示）。解决这部分，看看更新。rails嵌套窗体问题

此外，我试图找到一种方法来编辑每个嵌套的表单条目一次，目前我只能得到编辑，以编辑时显示在同一表单上的所有嵌套表单条目。理想情况下，我希望每个职位旁边的链接能够编辑只有一个条目，而不是在编辑模式下打开的所有条目。

用户控制器

# renders the users/new.html.erb form 
def new 
    @user = User.new 
    @user.work_histories.build # used for nested attributes in forms 
end 


# renders the users/edit.html.erb view form 
def edit 
    @user = User.find(params[:id]) 
    @user.work_histories.build # used for nested forms 
end 

# white listed form attributes for user and also for nested attributes (work history, qualifications, etc...). 
def user_params 
    params.require(:user).permit(:first_name, :last_name, :email, :phone, :current_job_title, :password, :password_confirmation, 
        work_histories_attributes: [:user_id, :id, :job_title, :company, :description, :city, :state,:start_date, :end_date]) 
end

用户模型用户

 # allows for nested attributes in the user views. 
    accepts_nested_attributes_for :work_histories, allow_destroy: true, 
    reject_if: lambda {|attributes| attributes['job_title'].blank?}

WorkHistory模型

belongs_to :user, optional: true

展示图。该模式显示first_name的用户字段，但不显示工作历史记录字段。

<!-- modal --> 
<div class="modal fade" id="experienceModal" tabindex="-1" role="dialog" aria-labelledby="experienceModal" aria-hidden="true"> 
    <div class="modal-dialog"> 
    <div class="modal-content"> 

     <div class="modal-header"> 
     <button type="button" class="close" data-dismiss="modal" aria-hidden="true"><i class="fa fa-times fa-fw" aria-hidden="true"></i></button> 
     <h4 class="modal-title" id="myModalLabel">Experience</h4> 
     </div> 

     <div class="modal-body"> 

     <!-- one-to-many nested attributes --> 
     <%= form_for(@user) do |f| %> 

      <%= f.label :first_name %> 
      <%= f.text_field :first_name, size: 40, autofocus: true, class: 'form-control' %> 

     <%= f.fields_for :work_histories do |ff| %> 

      <%= ff.label :job_title %> 
      <%= ff.text_field :job_title, size: 40, autofocus: true, class: 'form-control' %> 

     <% end %><!-- fields_for --> 

     <%= f.submit 'Save', class: 'btn btn-primary' %> 

     </div><!-- modal body --> 

     <div class="modal-footer"> 
      <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> 
     </div> 

     <% end %><!-- form_for --> 

    </div><!-- modal-content --> 
    </div><!-- modal dialog --> 
</div><!-- modal -->

UPDATE： 好吧，我想通了，如何让形式显示空的，所以我可以有用户数据，而不是表格与现有的用户数据被显示。只需在视图中添加WorkHistory.new。

<%= form_for @user do |user_form| %> 

    <%= user_form.label :first_name %> 
    <%= user_form.text_field :first_name, autofocus: true, class: "form-control" %> 

    <%= user_form.fields_for :work_histories, WorkHistory.new do |wh_fields| %> 
     job: <%= wh_fields.text_field :job_title %> 
    <% end %> 

<% end %>

如果有人在将来发生磕磕碰碰，则更新此更新。为了获得一个空白的嵌套表单，以便用户输入数据，请参阅原始问题中的UPDATE部分。

要实际编辑现有的嵌套表单记录，请参见下面的内容，必须同时传递用户标识和工作历史标识。

<table> 
    <!-- one-to-many association to loop through a users qualifications --> 
    <% @user.work_histories.each do |w| %>   
<tr> 
    <td>   
    <h4><b><%= link_to w.job_title, edit_user_work_history_path(user_id: @user.id, id: w.id) %></b></h4> 
    <!--<h4><b><%= link_to w.job_title, edit_user_work_history_path(user_id: @user.id, id: w.id), data: {toggle: "modal", target: "#experienceModal"} %></b></h4>--> 
    </td> 
</tr> 
<tr> 
    <td> 
    <%= w.company %> 
    </td> 
</tr> 
<tr> 
    <td> 
    <%= w.start_date.strftime("%b %Y") %> - <%= w.end_date.strftime("%b %Y") %> 
    </td> 
</tr> 
<tr> 
    <td> 
    <%= w.city %>, <%= w.state %> 
    </td> 
</tr> 
<tr> 
    <td> 
    <br /> 
    <%= w.description %> 
    </td> 
</tr> 
<tr> 
    <td> 
    <br /> 
    <hr> 
    </td> 
</tr>  
<% end %>
