Python 显示4个表单，但最后一个表单不工作

谢谢你抽出时间

我一直在尝试在同一模板上显示4个表单，并根据submit按钮向正确的表单发送POST请求。 前3个工作正常，只有最后一个（Estoque）不保存对象。当我检查请求时，post sims就可以了

views.py：

@login_required
@allowed_users(allowed_ones=['Admin'])
def test_view(request, id):
    prod = Produto.objects.get(id=id)

    prod_form = ProdutoForm()
    img_form = ImagemForm()
    model_form = ProdutoForm()
    storage_form = ProdutoForm()

    prod_query = Produto.objects.all()
    img_query = Imagem.objects.all()
    model_query = Modelo.objects.all()
    storage_query = Estoque.objects.all()

    t1 = 'no'
    t2 = request.POST
    if request.method == 'POST' and 'producting' in request.POST:
        print('PROD')
        prod_form = ProdutoForm(request.POST, instance=prod)
        t1 = 'product'
        t2 = request.POST
        if prod_form.is_valid():
            prod_form.save()

    elif request.method == 'POST' and 'img' in request.POST:
        print('IMG')
        img_form = ImagemForm(request.POST, request.FILES)
        t1 = 'img'
        t2 = request.POST
        if img_form.is_valid():
            img = img_form.save(commit=False)
            img.product = prod
            img.save()

    elif request.method == 'POST' and 'model' in request.POST:
        print('MODEL')
        model_form = ModeloForm(request.POST)
        t1 = 'model'
        t2 = request.POST
        if model_form.is_valid():
            model_form.save()

    elif request.method == 'POST' and 'storge' in request.POST:
        print('STORAGE')
        storage_form = EstoqueForm(request.POST, product=prod)
        t1 = 'storage'
        t2 = request.POST
        if storage_form.is_valid():
            storage_form.save()


    else:
        prod_form = ProdutoForm(instance=prod)
        img_form = ImagemForm()
        model_form = ModeloForm()
        storage_form = EstoqueForm()

    context = {
        'prod': prod,
        'prod_query': prod_query,

    product = models.ForeignKey(Produto, on_delete=models.SET_NULL, null=True, related_name='storage')
    tamanho = models.CharField(max_length=100, choices=tamanhos)

在第四种形式中，不要使用“存储”而使用“产品”，可能是这样的：

elif request.method == 'POST' and 'product' in request.POST:
    storage_form = EstoqueForm(request.POST, instance=prod)
    t1 = 'storage'
    t2 = request.POST
    if storage_form.is_valid():
        storage_form.save()

---

我不得不面对的问题是，在没有外键字段[product]的情况下显示存储表单（EstoqueForm），然后

if storage_form.is_valid():
     stg = storage_form.save(commit=False)
     stg.product = prod
     stg.save()

我所说的prod是指更新视图id中的de Produto.object。我试过使用instance=prod等。 但真正的问题在于验证表单。在我的模型中，我得到了一个干净的方法，该方法从一个模型中获取一个字段，该模型的Produto是与外键相关的，而Estoque是与Produto相关的外键。最后，我尝试在存储表单上设置de product，然后验证它是否有效，并尝试设置

 storage_form = EstoqueForm(request.POST, initial = {'product': prod}

也不管用。 我得到的解决方案是将field产品放回存储表单。将存储表单打印为，并仅将prod作为要选择的选项

update_product.amp.html

---

尝试使用else语句中的form.errors和form.non_field_errors在表单上打印错误。这会告诉你出了什么问题。我已经在模板上试过了。它什么也没给我看。你说的其他是什么意思？在通过上下文传递的变量上分配它，并将{{variable}设置到{{storage\u form.as\u p}}下的每个右下方？否，在视图函数中打印错误。if form.is\u valid（）//执行其他操作：打印（form.errors）打印（form.non\u字段\u errors）。查看错误是什么。它为模型上的clean方法获取了一个错误。它返回我非类型对象没有模型属性

            <h2>{{storage_form.non_field_errors}}</h2>

i understand that probably ain't the right way but was the one that i got for now.
