django中view.py中的无效语法错误

Question

I can't figure out what i've done wrong here. In my views.py.

def register(request):
    if request.method == 'POST'
        form = UserCreationForm(request.POST)
        if form.is_valid():
            username = form.cleaned_data.get('username')
            messages.success(request, f'Account created for {username}!')
            return redirect('home')
    else:
        form = UserCreationForm()
    return render(request, 'users/register.html', {'form': form})

Answer 1

You are missing a colon on the following line

if request.method == 'POST'

It should look like this

if request.method == 'POST':

Answer 2

def register(request):
if request.method == 'POST':   #The colon is missing here
    form = UserCreationForm(request.POST)
    if form.is_valid():
        username = form.cleaned_data.get('username')
        messages.success(request, f'Account created for {username}!')
        return redirect('home')
else:
    form = UserCreationForm()
return render(request, 'users/register.html', {'form': form})

Answer 3

您当前的第二行最后需要一个:语句，所以它应该是：

if request.method == 'POST':
