Question

我正在使用Omnicontacts Gem来提取联系人列表。到目前为止有效。我可以获取联系人并使用它们填充表单，以便我可以将它们传递给我的Contacts Controller以保存在联系人模型中。

我已经查看了Rails Cast＃165的指导和Stackoverflow上的几篇帖子。但是我似乎无法破解这个坚果。感觉我错过了一些基本的东西，并且让我感到沮丧。

编辑：问题重述

我遇到的麻烦是没有联系人记录被写入内存。请参阅下面的更新日志部分。实际上，我正在尝试提交多条记录，只有最后一条记录被提取。这实际上并没有保存到模型中，然后导致其他问题。这似乎是由于调用NEW引起的。通过将方法更改为CREATE，它现在保存列表中的最后一项。但是，表单中未列出的任何字段都将保存为nil，这会导致其他问题。

从控制台运行：

$Contact.create([{ user_id: '1', first_name: 'sam'}, { user_id: '1', first_name: 'Dean'}])

在Contact模型中创建两个新记录。因此，我试图弄清楚如何从表单中实现这一点。基本上

可以在自己的模型中嵌套表单吗？我应该先将联系人保存到临时表吗？看来应该有一个“Rails”方式来做到这一点。任何意见是极大的赞赏。该视图属于控制器的导入部分。

控制器：

def new
  @contact = Contact.new
  redirect_to action: 'index'
end

def edit
end

def create
  @user = current_user
  @contact = @user.contacts.new(contact_params)
  @contact.save
  redirect_to action: 'index'
end

def import
  @import = request.env['omnicontacts.contacts']
  respond_to do |format|
    format.html
  end
end

查看：

<div class="row">
  <div class="small-12">
    <%= simple_form_for Contact.new do |f| %>
        <% unless @import.nil? %>
            <% @import.each do |c| %>
                <%= f.input :first_name, input_html: {value: c[:first_name]} %>
                <%= f.input :last_name, input_html: {value: c[:last_name]} %>
                <%= f.input :email_home, input_html: {value: c[:email]} %>
                <%= f.input :phone_home, input_html: {value: c[:phone_number]} %>
            <% end %>
        <% end %>
        <div class="actions" align="right">
          <%= f.button :submit %>
        </div>
    <% end %>
  </div>
</div>

当我检查我的表记录501实际上并不存在，但我的应用程序确实存在。

尝试像这样更改视图代码

<div class="row">
    <div class="small-12">
      <%= simple_form_for Contact.new do |f| %>
        <% unless @import.nil? %>
          <% @import.each do |c| %>
              <%= f.input :first_name, input_html: {value: c[:first_name]} %>
              <%= f.input :last_name, input_html: {value: c[:last_name]} %>
              <%= f.input :email_home, input_html: {value: c[:email]} %>
              <%= f.input :phone_home, input_html: {value: c[:phone_number]} %>
          <% end %>
        <% end %>
        <div class="actions" align="right">
          <%= f.button :submit %>
        </div>
      <% end %>
     </div>
   </div>

Answer 2

所以我试图做的事情是不可能的。最终需要创建一个Import Controller，以便我可以通过User模型调用嵌套的Controller表单。

<div class="row">
  <div class="small-12">
    <%= simple_form_for(@user, url: import_path) do |f| %>
      <%= f.simple_fields_for :contacts, @contacts do |contact| %>
        <%= render 'contact_fields', f: contact %>
      <% end %>
    <div class="actions" align="right">
      <%= f.submit class:"button tiny" %>
    </div>
    <% end %>
  </div>
</div>
