Passing a param works locally but not on Heroku

Question

For some reason, Heroku doesnt pass the param, which gives me a NoMethod error.

This is my controller create action:

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

The form passes the params["data"], this is my log on localhost, showing that the param passed:

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"}

And this is the log on heroku:

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"}

Finally, this is the form in case needed:

 <%= 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 %>

As you can see, it's not passing the params["data"] at all, not sure why, since its the same code... any guesses?

On this try, a few minutes later, the param was loaded:

This is the new action on the controller:

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

Answer 1

The issue was fixed, not sure why, but bootstrap sortable table removes the params once is pressed, thats why it was acting randomly, i didnt notice that sometimes i pressed the button to sort them and others dont, once i figured this out, i remove the sortable class and make the order in the controller instead, and it actually looks better now, this is how the controller changed, in case needed:

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

That fixed it! thanks a lot for your help!!
