django - 如何在 django 中获取错误文本？

Question

当我将值保存到数据库中时，我想获取异常文本。

视图.py：

if request.method == 'POST':
    form = CustomerForm(request.POST)        

    if form.is_valid():
        try:
            customer = form.save(commit=False)           
            customer.save()
        except DatabaseError:
            message = 'Database Error: ' + str(??? text error ???)

Answer 1

except您可以在语句中传递第二个变量。它将保存文本错误。见下文

if request.method == 'POST':
    form = CustomerForm(request.POST)        

    if form.is_valid():
        try:
            customer = form.save(commit=False)           
            customer.save()
        except DatabaseError, text_error:
            message = u'Database Error: {0}'.format(text_error)

Answer 2

您可以打印如下所示的异常。

如果 request.method == 'POST'：
    表单 = CustomerForm(request.POST)        


if form.is_valid():
    try:
        customer = form.save(commit=False)           
        customer.save()
    except DatabaseError as e:
        message = 'Database Error: ' + str(e.message)
