Is there any what to change data display in readonly InputField of ModelChoiceField, but retain the primary key of the object for submitting the form?

views.py



class BookingCreateView(LoginRequiredMixin, CreateView):

    login_url = 'login'

    form_class = BookingForm

    template_name = 'booking_add.html'

    success_url = reverse_lazy('booking_list')



    def get_initial(self):

        initial = super(BookingCreateView, self).get_initial()

        initial['date'] = datetime.datetime.strptime(self.request.GET.get('date'), '%d-%m-%Y')

        initial['room'] = get_object_or_404(Room, id=self.request.GET.get('room'))

        initial['start'] = get_object_or_404(Period, number=self.request.GET.get('start'))

        return initial



    def form_valid(self, form):

        form.instance.user = self.request.user

        return super().form_valid(form)



forms.py

class BookingForm(forms.ModelForm):

    class Meta:

        model = Booking

        fields= ['room', 'date', 'start', 'end']



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

        initial_args = kwargs.get('initial', None)

        if initial_args:

            super(BookingForm, self).__init__(*args, **kwargs)

            self.fields['room'].widget = forms.TextInput()

            self.fields['start'].widget = forms.TextInput()

            self.fields['room'].widget.attrs['readonly'] = True

            self.fields['date'].widget.attrs['readonly'] = True

            self.fields['start'].widget.attrs['readonly'] = True

            self.fields['end'].queryset = Period.objects.get_available_periods(

                initial_args['room'], initial_args['date'], initial_args['start'])





    def clean(self):

        cleaned_data = super(BookingForm, self).clean()

        now = timezone.localtime(timezone.now())



        bookings = Booking.objects.filter(room=cleaned_data['room'], date=cleaned_data['date'])

        booking_start_time = datetime.datetime.combine(cleaned_data['date'], cleaned_data['start'].start, timezone.get_current_timezone())

        booking_end_time = datetime.datetime.combine(cleaned_data['date'], cleaned_data['end'].end, timezone.get_current_timezone())



        for booking in bookings:

            if booking.check_overlap(booking_start_time, booking_end_time):

                raise forms.ValidationError



        if now > datetime.datetime.combine(cleaned_data['date'],

            cleaned_data['start'].end, timezone.get_current_timezone()):

            raise forms.ValidationError



        return cleaned_data



booking_add.html

{% block content %}

    <main>

        <div class="reg-form">

            <form class="form" method="post" action="">

                {% csrf_token %}

                <label for="room">Phòng</label>

                {{ form.room }}

                <label for="date">Ngày</label>

                {{ form.date }}

                <label for="start">Ca bắt đầu</label>

                {{ form.start }}

                <label for="end">Ca kết thúc</label>

                {{ form.end }}

                <button type="submit">Đăng ký</button>

            </form>

        </div>

    </main>

{% endblock %}

The page is rendered like this:

The thing I want is that the input below label 'Phòng' which mean Room, filled with the room object method str() not the primary key of Room object and the submitting process still send the primary key.Is there any way to achieve that? Note: the first three fields need to be read only and their data are given via GET request.

I know that however I want the field room to be read-only and select widget doesn't have that attribute.
