传递一个参数在本地工作但不在Heroku上工作

出于某种原因，Heroku没有通过param，这给了我一个NoMethod错误。

这是我的控制器创建动作：

def create
  # @stock = Stock.new(params[:data].keys, params[:data].values)
  @user = current_user
  @data = params["data"]
  @data.each do |d|
    @stock = Stock.create(my_params(d))
    if @stock.altas == nil && @stock.bajas == nil
      @stock.destroy
    else
      @stock.save
    end
    @item = Item.find(@stock.item_id)
    if @stock.altas != nil
      @item.quantity =  @item.quantity + @stock.altas
      @item.save
    end
    if @stock.bajas != nil
      @item.quantity = @item.quantity - @stock.bajas
      @item.save
    end
  end
  # ItemMailer.reporte_diario_email(@user).deliver_now

  redirect_to change_path, notice: 'Cambio en el inventario creado.'

end

表单传递了params [“data”]，这是我登录localhost，显示param通过了：

Processing by StocksController#create as HTML
 Parameters: {"utf8"=>"✓",    "authenticity_token"=>
"BB/8I4Bypwa8aga8x7wCi6QWF2I9tPTuWbIitYpdpESCvOeFfPnDuaf7PjFYkjuzuz6N45t9phdbVZ1QNB3DeA==", "data"=>[{"altas"=>"", "bajas"=>"", "item_id"=>"1"}, {"altas"=>"5", "bajas"=>"", "item_id"=>"5"}, {"altas"=>"", "bajas"=>"", "item_id"=>"3"}, 
{"altas"=>"2", "bajas"=>"", "item_id"=>"2"}, {"altas"=>"", "bajas"=>"",
"item_id"=>"4"}], "commit"=>"Update"}

这是heroku上的日志：

Processing by StocksController#create as HTML
 2016-10-25T23:23:32.440253+00:00 app[web.1]:   Parameters: {"utf8"=>"✓",   "authenticity_token"=>"wye0t6tc1BQV15WgQsoVsnvSuwMwA8bCT77JWRqsuRNikVSq+OGhed5oIGczCmdGHl0/f+Y4/KL/YVEOOrzv/g==", "commit"=>"Update"}

最后，这是需要时的表格：

 <%= form_tag stocks_path  do %>

  <% @items.each do |item| %>
  <%= fields_for 'data[]', @stock do |stock| %>

  <tr>
    <td><%= item.nombre %></td>
    <td><center><%= item.material %></center></td>
    <td><center><%= item.marca %></center></td>
    <td><center><%= item.espesor %> mm</center></td>
    <td><center><%= stock.text_field :altas %></center></td>
    <td><center><%= stock.text_field :bajas %></center></td>
    <%= stock.hidden_field :item_id, :value => item.id %>
    <% end %>

  <% end %>
  </tr>
 </table>
 <div class="form-group">
 <div class="col-sm-offset-3 col-sm-5">
 <%= submit_tag "Update", class: "btn btn-primary" %>
 <% end %>

正如你所看到的，它根本没有传递params [“data”]，不知道为什么，因为它的代码相同......任何猜测？

在这次尝试中，几分钟后，param被加载了：

这是控制器上的新操作：

def new
 @stock = Stock.new
 @items = Item.all
end

答案 0 :(得分：0)

这个问题已得到解决，不知道为什么，但是bootstrap sortable table会删除params一次被按下，这就是为什么它是随机行动的，我没注意到有时我按下按钮来排序它们而其他人不会，一旦我想到这个out，我删除了sortable类并在控制器中进行了命令，现在实际上看起来更好了，这就是控制器改变的方式，如果需要的话：

def new
@stock = Stock.new
@items = Item.all.order(:nombre).order(:material).order(:marca).order(:espesor)
end

修好了！ 非常感谢你的帮助!!
