在Django中创建订单菜单

Question

我正在尝试为Canteen创建一个菜单，该菜单中的admin正在更新/添加产品名称和价格。但是，我如何检索客户订购的商品？

<table class="table">
          <thead class="thead-dark">
            <tr>
              <th scope="col">Item Name</th>
              <th scope="col">Item Price</th>
              <th scope="col">Item Type</th>
              <th scope="col">Quantity</th>
            </tr>
          </thead>
          {% for temp in food_dict %}

          <tr>

            <td>{{ temp.food_name }}</td>
            <td>{{ temp.food_price }}</td>
            <td>{{ temp.type }}</td>

            <td>
              <input type="button" onclick="dec({{ forloop.counter }})" class="btn btn-light" value="-"/>
              <input type="button" id="{{ forloop.counter }}" name="temp.food_name" class="btn btn-light" value="0"/>
              <input type="button" onclick="inc({{ forloop.counter }})" class="btn btn-light" value="+" />
              {{ temp.food_name }}
            </td>
          </tr>`enter code here`
          {% endfor %}
      {% endif %}
      </table>

这是models.py，管理员在其中添加食物

class Food_items(models.Model):
food_name = models.CharField(max_length=264,unique=True)
food_price = models.CharField(max_length=264)
type = models.CharField(max_length = 6,choices = 
type_choices,default='tiffin')


def __str__(self):
    return self.food_name

这是views.py

def viewmenu(request):
    food_list = Food_items.objects.order_by('food_name')
    food_dict = {'food_dict':food_list,'v':1}
    return render(request,'first_app/viewmenu.html',context=food_dict)
