Сбой ограничения FOREIGN KEY - Django, SQLite3

/ 13 апреля 2020

Мое приложение позволяет Tenant профилям подавать заявки на Property просмотры, которые перечислены в Landlord профилях. Я не могу связать две таблицы вместе, я не могу получить ошибку FOREIGN KEY constraint failed.

views.py 

from django.shortcuts import render, redirect
from projects.models import Properties, Property_Applications, Property_Reviews
from users.models import Landlord_Profile, Tenant_Profile
from django.contrib.auth.decorators import login_required
from django.contrib import messages
from .forms import CreatingListingForm, ListingApplicationForm

def property_apply(request, pk):
    project = Properties.objects.get(pk=pk)
    applyButton = ListingApplicationForm(request.POST)
    profile = request.user.tenant_profile
    if request.method == "POST":
        link = applyButton.save(commit=False)
        link.tenant_apply = profile
        link.listing=project
        link.save()
        messages.success(request, f'You have applied!')
        return redirect('/tenantportal/')
    else:
        link = applyButton
    context = {'project': project, 'applyButton': link}
    return render(request, 'application_submit.html', context)
