未提交简单嵌套表单中的隐藏字段

环境:Rails 3.1.0,Ruby 1.9.2

我有投资组合模型,其中has_many位置为has_one资产。

这是位置模型的架构:

create_table "positions", :force => true do |t|
    t.integer  "portfolio_id"
    t.integer  "asset_id"
    t.decimal  "holding_percentage"
end

当用户创建投资组合时,他/她应输入投资组合名称,然后通过添加股票代码添加头寸。 Jquery执行其操作并显示资产的全名,并将asset_id插入隐藏字段。

我正在使用nested_form和simple_form,如下所示:

<%= simple_nested_form_for @portfolio  do |f| %>

    <%= f.input :name, :placeholder => 'Your portfolio name' %>  

    <%= f.fields_for :positions do |position_form| %>

        <%= text_field_tag 'asset-ticker', nil, :class => 'asset-ticker' %>         
        <span class="asset-name"></span>
        <%= position_form.text_field :holding_percentage, :class => 'asset-perc' %>
        <%= position_form.hidden_field :asset_id, :class => 'asset-num', :as => :hidden %>

        <%= position_form.link_to_remove "Remove this position", :class => 'asset-rem-link' %>
    <% end %>

    <p><%= f.link_to_add "Add a Position", :positions, :class => 'asset-add-link' %></p>  

    <%= f.button :submit %>

<% end %>

问题是隐藏字段中的asset_id值未提交。参数如下:

Parameters: {"utf8"=>"✓", "authenticity_token"=>"hmvoGHF9GzpPsohQQ2MwhWk4FzhVVrf+IqoChHgftEs=",  
    "portfolio"=>{"name"=>"needhelpnow", 
                  "positions_attributes"=>
    {"new_1316730954406"=>{"holding_percentage"=>"11", "asset_id"=>"", "_destroy"=>"false"}, 
     "new_1316730961085"=>{"holding_percentage"=>"22", "asset_id"=>"", "_destroy"=>"false"}, 
     "new_1316730971587"=>{"holding_percentage"=>"33", "asset_id"=>"", "_destroy"=>"false"}}}, 
     "commit"=>"Create Portfolio"}

1 个答案:

答案 0 :(得分:0)

事实证明,问题在于我用隐藏字段的值写了:

('.asset-num').html(data.id)

而不是:

('.asset-num').val(data.id)
