更新我是您推荐的编辑来源，并在此处包含我的路线，但当我尝试编辑操作时会发生这种情况

No route matches {:action=>"update", :controller=>"uzivatel", :datum=>nil}, missing required keys: [:datum]

并且日志是

我使用的是rails 5，我不知道为什么它报告我找不到id为的食物在线，看起来它没有从形式加载food_id我最终欢迎想法如何以更好的方式重写它。无论如何，感谢任何建设性的建议。

 @order.update(food_id: Food.find(params[:food_id]))

型号：

User model has many orders 
Food has many orders
Order belong to user and  Food

UzivatelController

class UzivatelController < ApplicationController
  before_action :authenticate_user!
  def index
@date = params[:date] ? Date.parse(params[:date]) : Date.today
@orders = Order.where(:datum => @date.beginning_of_week..@date.end_of_week).where(:user_id => current_user.id)
  end

 def edit
   @order=Order.where(:datum => params[:datum] ).where(:user_id => current_user.id).first_or_create

  end
  def update
  @order=Order.where(:datum => params[:datum] ).where(:user_id => current_user.id).first_or_create
  params.permit(:food_id)
  if @order.update(food_id: Food.find(params[:food_id]).first)
    redirect_to uzivatel_index_path, notice: 'Objednavka uložena'
  else
   redirect_back(fallback_location: uzivatel_index_path)
  end
end


def delete
end
private
def order_params
  params.permit(:food_id)
end

我发现了一些问题。请尝试修复它们并重新运行代码。

update

中的UzivatelController行动

使用

@order.update(food_id: Food.find(params[:food_id]))

而不是

@order.update(food_id: Food.find(params[:food_id]).first)

在edit.html.erb

在url_helper中传递对象

<%= form_with url: uzivatel_update_path(datum: `your dataum value`, food_id: `your food id`), method: :put, local: true do |form| %>
<%= form.collection_select(@food_id, Food.all, :id, :name)%>
<%= form.submit %>
<% end %>

如果仍然遇到任何错误，请共享错误跟踪，以便我们可以轻松调试
