Question

听起来很简单，但我希望页面显示模型的数据库。

我使用ModelForm供用户输入，它将保存到我的模型中。现在，我要渲染整个表格，而不仅仅是每个单独的表格。

forms.py

class My_Folio(forms.ModelForm):
    class Meta:
        model = my_data
        fields = ['symbol','buy_price','quantity']

views.py

def blockfolio(request):
    if request.method == 'POST':
        my_folio = My_Folio(request.POST)
        if my_folio.is_valid():
            symbol = my_folio.cleaned_data['symbol']
            buy_price =  my_folio.cleaned_data['buy_price']
            quantity =  my_folio.cleaned_data['quantity']
            instance = my_folio.save(commit=False)
            instance.save()
            return render(request, 'blockfolio/blockfolio.html', {'symbol':symbol, 'buy_price':buy_price, 'quantity':quantity, 'instance':instance})

模板：

{{instance}}这给了我用户提交后的输入，但是我想显示数据库中保存的所有输入。

也许您的帖子无效。在views.py中尝试此代码。

def blockfolio(request):
    if request.method == 'POST':
        my_folio = My_Folio(request.POST)
        if my_folio.is_valid():
            symbol = my_folio.cleaned_data['symbol']
            buy_price =  my_folio.cleaned_data['buy_price']
            quantity =  my_folio.cleaned_data['quantity']
            instance = my_folio.save(commit=False)
            instance.save()
            return render(request, 'blockfolio/blockfolio.html', {'symbol':symbol, 'buy_price':buy_price, 'quantity':quantity, 'instance':instance}) 
        else:
            print("request is invalid: {}".format(request.POST))
            return "bad request!", 500

用户提交表单后Django视图未呈现数据
