我想这里有个打字错误。您已经使用了
request.method==“post”
，它应该
request.method==“post”
。老实说，该支票是多余的，所以您应该删除它

def form(request):
    if request.method == "GET":
        form = CreateTabelogForm()
        context = {
            "form":form
        }
        return render(request,"Tabelog/form.html",context)

    else:
        form = CreateTabelogForm(request.POST or None)
        if request.method == "post" and form.is_valid():
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
           # remove this code
该代码的重构版本：

def form(request):
    form = CreateTabelogForm(request.POST or None)
    if request.method == "POST":
        if form.is_valid():
           form.save()
           return redirect("Tabelog:list")
     context = {
        "form":form
     }
     return render(request,"Tabelog/form.html",context)
非常感谢你！我终于可以解决这个问题了！令人惊叹的。那么请考虑一下。谢谢 
def form(request):
    form = CreateTabelogForm(request.POST or None)
    if request.method == "POST":
        if form.is_valid():
           form.save()
           return redirect("Tabelog:list")
     context = {
        "form":form
     }
     return render(request,"Tabelog/form.html",context)
