Как связать представления с формами и сохранить это в db Django

У меня есть форма, которая пытается подключиться к нескольким представлениям, где я получаю множественный выбор формы ModelChoice, и я фактически не знаю, как сохранить их в db или подключить их к моей модели "WorkLog"

Я получил ошибку валидации, которую я вызвал в функции "create_worklog" с messages.error

Any advices pls?

models.py

class WorkLog(models.Model):
    worklog_date = models.DateField(verbose_name='Дата', )
    created_date = models.DateTimeField(auto_now_add=True)
    modified_date = models.DateTimeField(auto_now=True)
    author = models.ForeignKey(User, blank=True, related_name='contractor_user',on_delete=models.CASCADE)

    contractor_counter = models.ForeignKey(CounterParty, blank=True, related_name='contractor_user', on_delete=models.CASCADE)

    contractor_object = models.ForeignKey(ObjectList, blank=True, related_name='contractor_user', on_delete=models.CASCADE)

    contractor_section = models.ManyToManyField(SectionList, default=None, related_name='contractor_user'
    description = models.TextField(blank=True,)

forms.py

class WorkLogForm(forms.ModelForm):
    worklog_date = forms.DateField(label='Дата', widget=forms.DateInput(
        attrs={'type': 'date', 'class': 'form-control', 'placeholder': 'Введите дату'}))

    description = forms.CharField(label='Описание',
                                  widget=forms.Textarea(attrs={'class': 'form-control', 'placeholder': 'Описание'}))

    class Meta:
        model = WorkLog
        fields = (
            'worklog_date', 'contractor_counter', 'contractor_object', 'contractor_section', 'description'
        )

views.py

    get_counter = request.GET.get('counter')

    return render(request, 'partials/objects.html', context)

        if form.is_valid():
            work_log = form.save(commit=False)
            work_log.author = request.user
            work_log.contractor_counter = counter_party
            work_log.contractor_object = object_list(request).objects
            work_log.contractor_section = sections_list(request).sections
            work_log = form.save()
            messages.success(request, 'Everything okay', {'work_log': work_log})
            return redirect('create_worklog')
        else:
            messages.error(request, 'Validation error')
            return redirect('create_worklog')
    else:
        form = WorkLogForm()
    context = {'counter_party': counter_party, 'form': form}
    return render(request, 'zesshi_test/home.html', context)
