How to filter a request on multiple fields from a form in Django?

Question

Django

There is a table with contacts in which it is necessary to return elements according to the data from the filter form. There are several filters, one for each field of the model. I can't figure out how to pass data from forms through a GET request to a filter in order to send the correct list of objects to the template. Can someone tell me how to implement such filtering.

contacts.html

<form class="d-flex" method="get" action="{% url 'contacts' %}">
                              {% csrf_token %}
                              {{ subjectFilter.subject }}
                              {{ typeFilter.type }}
                              {{ infoFilter.info }}
                              {{ dateFilter.date }}
                              <button type="submit" class="btn btn-outline-success">Искать</button>
                          </form>

views.py

class ContactListView(View):
    def get(self, request):

        contacts = Contact.objects.all()

        addContact = AddContactForm
        editContact = EditContactForm
        addType = AddTypeForm
        addSubject = AddSubjectForm

        typeFilter = TypeFilter
        subjectFilter = SubjectFilter
        infoFilter = InfoFilter
        dateFilter = DateFilter

        return render(request, 'contacts.html', {
            'contacts': contacts,
            'addContact': addContact,
            'addType': addType,
            'addSubject': addSubject,
            'editContact': editContact,
            'typeFilter': typeFilter,
            'subjectFilter': subjectFilter,
            'infoFilter': infoFilter,
            'dateFilter': dateFilter
        })

    def post(self, request):
        if request.method == 'POST':
            form = AddContactForm(request.POST)
            if form.is_valid():
                # сохранение формы
                contact = Contact()  # новый объект
                contact.type = form.cleaned_data['type']
                contact.subject = form.cleaned_data['subject']
                contact.info = form.cleaned_data['info']
                contact.date = datetime.date.today()
                contact.KEY = contact.id
                contact.save()
                return HttpResponseRedirect('/contacts/')

models.py

class Type(models.Model):
    name = models.CharField('Название', max_length=50)

    def __str__(self):
        return self.name


class Subject(models.Model):
    name = models.CharField('Имя', max_length=50)

    def __str__(self):
        return self.name


class Contact(models.Model):
    KEY = models.IntegerField('Идентификатор', default=None, null=True, blank=True)
    info = models.CharField('Инфо', max_length=100)
    date = models.DateField(default=datetime.date.today(), verbose_name='Дата добавления')
    type = models.ForeignKey(Type, verbose_name='Тип', on_delete=models.CASCADE, default=None)
    subject = models.ForeignKey(Subject, verbose_name='Человек', on_delete=models.CASCADE, default=None)

    def __str__(self):
        return self.info

Answer 1

1. Why is there a form for each filter, can it still lead to one?
2. AddContactForm is the same ModelForm, so work with it correctly, and not through cleaned_data
3. Either create a dictionary from filters and do it objects.filter(**словарь)dynamically using a Q-object.
