如何获取用户ID

Question

I am working on a website using Django. I'm having a difficult time playing around codes, how do I get the ID of a user without passing a primary key (id, pk) in the URL. My code below does not give me a solution to getting the ID of a particular user. When I print (user) it prints the current user logged in. Is there a way to get the ID of other users?

def home(request):
    p=Profile.object.filter(user=request.user)
    u=p.user
    send_request=FriendRequest.objects.filter(from_user=p.user)

def send_request(request, id):
    user=get_object_or_404(User, id=id) 
    frequest=FriendRequest.get_or_creat(from_user=request.user, to_user=user).first()

    path('home', home_view, name='home')

<a href='{% url 'site:send_request'  profile.user.id %}'>Add friend<a>

Answer 1

Use a form with POST method and send the user_id as a parameter but hidden to the user.

<form method="post" action="{% url 'your_url' %}">
    {% csrf_token %}
    <input type="hidden" name="user_id" value="{{ user_id }}" />
    <button type="submit">Add Friend</button>
</form>

You can access the parameter in the view like this

request.POST.get('user_id')
