远程表单将找不到关联ID

Question

我的节目有WorkOrder :has_many LineItems。我有一个部分(/views/line_items/_add_line_item.html.erb)与WorkOrder#Show (/views/work_orders/show.html.erb)渲染到remote true。但是，在提交表单时，帖子失败，因为ActiveRecord::RecordNotFound (Couldn't find WorkOrder with 'id'=)。我在这做错了什么？

/controllers/李讷_items_controller.日本#create

def create
  @work_order = WorkOrder.find(params[:work_order_id])
  @line_item = @work_order.line_items.build(line_item_params)
  respone_to do |format|
    if @line_item.save
      format.html { redirect_to @work_order, notice: 'added line item' }
      format.js
    else
      redirect_to @work_order
    end
  end
end

/controllers/李讷_items_controller.日本#李讷_item_par AMS

def line_item_params
  params.permit(:line_item, :description, :quantity, :price_adjustment, :work_order_id)
end

/controllers/work_orders_controller.日本#show

def show
  @line_items = @work_order.line_items
  @new_line_item = @work_order.line_items.new
end

/views/work_orders/show.HTML.而不

[...]
<%= render 'line_items/add_line_item', wo: @work_order %>
[...]

/views/李讷_items/_add_李讷_item.HTML.而不

<%= form_for(@new_line_item, remote: true) do |form| %>

    <%= form.collection_select(:inventory_sku_id, Inventory::SKU.all, :id, :descriptive_id) %>

    <%= form.text_field :description, id: :line_item_description %>

    <%= form.number_field :quantity, id: :line_item_quantity %>

    <%= form.hidden_field :work_order_id, id: :work_order_id, value: wo.id %>

  <div class="actions">
    <%= form.submit "New Item" %>
  </div>

<% end %>

创建新行时的控制台输出：

Answer 1

如何为line_item_params [：work_order_id]更改parms [：work_order_id]？通常在对params进行清理时，您将访问模型数据。

Answer 2

您的模型是否嵌套？将表单更改为：

<%= form_for(wo, @new_line_item, remote: true) do |form| %>

编辑

将line_item_params更改为require：line_item

def line_item_params
  params.require(:line_item).permit(:description, :quantity, :price_adjustment, :work_order_id, :inventory_sku_id)
end
