Answer 1

try like this

@login_required()
def data(self, request):
 if request.method == "POST": #this line
    form = CreatePost(request.POST)
    if form.is_valid():
        post = form.save(commit=False) #new line
        post.author = self.request.user #this line
        post.save() #this line
        return redirect(data)
else:
    form = CreatePost()
context = {
    "form": form
}
return render(request, "sms/data.html", context)

if request.POST == "POST":

应该是：

if request.method == 'POST':
