如何获取我正在查看的用户的用户名而不是当前登录的用户名

Question

I want to get the current profile viewing username and save it in instance.user . The problem is that I want to get the username of the user that is going to be rated for other users.

Here is my code:

def new_rate(request):
    if request.method == 'POST':
        form = RateForm(request.POST)
        if form.is_valid():
            instance = form.save(commit=False)
            try:
                instance.rater = request.user
    --------->  instance.user = !!!!! GET THE CURRENT  PROFILE VIEWING USERNAME !!!!!
                instance.validate_unique()
                instance.save()
                form.save_m2m()
                return HttpResponseRedirect('/user/' + request.user.username)

You can only get request.user.username if your user is authenticated. To check it use request.user.is_authenticated() .

So I think it would look somewhat like this:

def new_rate(request):
    if request.method == 'POST':
        form = RateForm(request.POST)
        current_user = request.user
        if form.is_valid() and current_user.is_authenticated():
            instance = form.save(commit=False)
            try:
               instance.rater = current_user
               instance.user = current_user
               instance.validate_unique()
               instance.save()
               form.save_m2m()
               return HttpResponseRedirect('/user/' + current_user.username)

But to me, your design sounds flawed. If you already use request.POST, you should POST the current profile's ID.

If for example you're viewing URL /users/500 and you have a form. Send the ID 500 and then in the view it should get the current profile user like:

from django.contrib.auth import get_user_model

User = get_user_model()

def new_rate(request):
    if request.method == 'POST':
        form = RateForm(request.POST)
        current_user = request.user
        profile_id = request.POST['profile_id']

        if form.is_valid() and current_user.is_authenticated():
            instance = form.save(commit=False)
            profile_user = User.objects.get(pk=profile_id)

            try:
               instance.rater = current_user
               instance.user = profile_user
               instance.validate_unique()
               instance.save()
               form.save_m2m()
               # it should  return us back to that profile, not the request.user's
               return HttpResponseRedirect('/user/' + profile_user.username)
