Question

我有一个模板，显示由formset对象表示的主要详细信息表单。那部分工作正常。我有一个只读的第二个细节模型，我希望在与主细节表格相同的模板上显示。

我的观点：

        var startDate = date.Date;
        var endDate = date.Date.AddDays(1);

        return db.Events
        .Where(e =>
            e.BedId == bed
            && e.Date >= startDate
            && e.Date < endDate)
        .Select(x => new EventViewModel()
        {
            Id = x.Id,
            Date = x.Date,
            StartTime = x.StartTime,
            EndTime = x.EndTime,
            Planned = x.Planned,
            EngineSN = x.EngineSN,
            Details = x.Details,
            Bed = x.Bed.Name,
            Category = x.Subcategory.Category.Name,
            Subcategory = x.Subcategory.Name,
            Project = x.Project.Name,
            Type = x.Type.ToString()
        })
        .ToList();

我已经阅读了很多关于这个主题的帖子，但似乎无法在我的模板上渲染第三个模型。这是我的模特。

def order_edit(request, pk):
  order = get_object_or_404(Orders, pk=pk)

  if request.method == "POST":
    form = OrderForm(request.POST, instance=order)

    if form.is_valid():
        order = form.save(commit=False)
        lineitem_formset = LineFormSet(request.POST, instance=order)

        if lineitem_formset.is_valid():
            order.save()
            lineitem_formset.save()
        #order.date_ordered = timezone.now()
        #order.save()
        return redirect('order_list')
else:
    form = OrderForm(instance=order)
    #lineitem_formset = LineFormSet(instance=Orders()) This was wrong. It was calling a new instance of Orders which was blank
    lineitem_formset = LineFormSet(instance=order)
    modification_formset = ModificationFormSet(instance=order)
return render(request, "orders/order_edit.html", {"form": form, "lineitem_formset": lineitem_formset,"modification_formset": modification_formset })

这是我尝试在模板上呈现的第三个模型。前两个作为formset的一部分呈现。 TIA。
