how to populate user field with current user in django models via forms?

Question

hi i am working on a django app. functionality that i am implementing is to let my user buy a internet pack from the website.

i have implemented the model, view, template and url so far. but in the form i am getting a drop down list of all the users registered on the app. i automatically want django to link the user with current logged in user and let him select the pack he wants to buy and populate the model(table) automatically.

My models.py

def get_deadline():
    return dt.today() + timedelta(days=30)

class CustomUser(AbstractUser):
    Address = models.CharField(max_length=500)

    def __str__(self):
        return self.username

class Plans(models.Model):
    plan_name = models.CharField(max_length=50)
    speed = models.IntegerField()
    price = models.FloatField()

    def __str__(self):
        return self.plan_name


class Orders(models.Model):
    user = models.ForeignKey(CustomUser, on_delete = models.CASCADE)
    pack = models.ForeignKey(Plans, on_delete = models.CASCADE)
    start_date = models.DateField(auto_now_add=True)
    end_date = models.DateField(default=get_deadline())
    is_active = models.BooleanField(default=True)

    def __str__(self):
        name = str(self.user.username)
        return name

my views.py

class UserBuyPlan(LoginRequiredMixin, View):
    template = 'plans/plan.html'
    #success_url = reverse_lazy('autos:all')
    success_url = reverse_lazy('home-home')

    def get(self, request):
        form = BuyPlanForm()
        ctx = {'form': form}
        return render(request, self.template, ctx)

    def post(self, request):
        form = BuyPlanForm(request.CustomUser,request.POST)
        if not form.is_valid():
            ctx = {'form': form}
            return render(request, self.template, ctx)

        make = form.save()
        return redirect(self.success_url)

my forms.py (i tried searching online and found this init implementation but it doesnt work)

class BuyPlanForm(forms.ModelForm):

    class Meta():
        model = Orders
        fields = "__all__"

    def __init__(self, *args, **kwargs):

        self.user = CustomUser
        super(BuyPlanForm, self).__init__(*args, *kwargs)
        self.fields['user'].initial = self.user

the photo of resulting form is attached below

ok so i found the answer. just had to change my view function a bit. if you want a detailed tutorial then please visit https://www.youtube.com/watch?v=-s7e_Fy6NRU&t=1840s he explains in a much better way.

class UserBuyPlan(LoginRequiredMixin, CreateView):
    model = Orders
    template_name = 'plans/plan.html'
    fields = ['pack']

    def form_valid(self, form):
        form.instance.user = self.request.user
        return super().form_valid(form)

and also had to add absolute url method to my orders model

class Orders(models.Model):
    user = models.ForeignKey(CustomUser, on_delete = models.CASCADE)
    pack = models.ForeignKey(Plans, on_delete = models.CASCADE)
    start_date = models.DateField(auto_now_add=True)
    end_date = models.DateField(default=get_deadline())
    is_active = models.BooleanField(default=True)

    def __str__(self):
        name = str(self.user.username)
        return name

    def get_absolute_url(self):
        return reverse('home-home')

rest everything is same.
