Uploading at least 3 images per Post

[Richard Balwane]

Hello,

With these models of Post and Images, I want to display and edit/delete the images along with the fields of the post. I have just added the Images model so I can have its fields in a Formset but the implementation of Model Formsets has challenged me.

class Post(models.Model):

    title = models.CharField(max_length=100)

    content = models.TextField()

    date_posted = models.DateTimeField(default=timezone.now)

    author = models.ForeignKey(User, on_delete=models.CASCADE)

    price = models.IntegerField(validators=[MinValueValidator(10), MaxValueValidator(10000000)], default=10,

                                help_text="Enter in Dollars, $.")

    featured       = models.BooleanField(default=False)

    active         = models.BooleanField(default=True)

    propertyType   = models.CharField(max_length=120, choices=TYPE_CHOICES, validators=[

                                    validate_propertyType], default='Villa',)

    area           = models.DecimalField(decimal_places=2, max_digits=20, null=True, blank=True,

                               help_text="Enter in Acres. Hint: 100 decimals = 1 acre = 0.405 hectares, 1 Sq. mile = 640 Acres, 1 decimal = 436 sq. feet = 40.5 sq. metres = 0.001 acres.")

    bedrooms       = models.SmallIntegerField(choices=BEDROOMS_CHOICES, null=True, blank=True)

    baths          = models.SmallIntegerField(choices=BATHROOMS_CHOICES, null=True, blank=True)

    garages        = models.SmallIntegerField(choices=GARAGES_CHOICES, null=True, blank=True)

    location       = models.CharField(

        max_length=120, null=True, help_text="Enter a Town/City where your Property is located.")

    propertyStatus = models.CharField(

        max_length=120, choices=STATUS_CHOICES, validators=[validate_propertyStatus], default='Sale')

    amenities      = models.TextField(null=True, blank=True,

                                 help_text="Enter separating with commas, e.g: Parking, Balcony, Swimming Pool, Tennis Courts, Outdoor Kitchen, Internet, Cable T.V, Concrete Flooring, ...")

    slug           = models.SlugField(null=True, blank=True)

    def __str__(self):

        return self.title

    

    def get_absolute_url(self):

        return reverse('post-detail', kwargs={'pk': self.pk})

def get_image_filename(instance, filename):

    title = instance.post.title

    slug = slugify(title)

    return "properties_pics/%s-%s" % (slug, filename)

class Images(models.Model):

    post            = models.ForeignKey(Post, on_delete=models.CASCADE,default=None)

    propertyImages  = models.ImageField(

        default="default.jpg", upload_to=get_image_filename, 

        help_text=" We must provide a clear Picture, preferably Landscape, not Portrait!")

    

    def save(self, *args, **kwargs):

        super().save(*args, **kwargs)

        img = Image.open(self.propertyImages.path)

        if img.height > 800 or img.width > 600:

            output_size = (600, 800)

            img.thumbnail(output_size)

            img.save(self.propertyImages.path)

Here is my Views.py, works well before the Formsets;

class PostListView(ListView):

    model = Post

    template_name = "maproperty/home.html"  # <app>/<model>_<viewtype>.html

    context_object_name = "posts"

    odering = ["date_posted"]

    paginate_by = 5

class UserPostListView(ListView):

    model = Post

    template_name = "maproperty/user_posts.html"  # <app>/<model>_<viewtype>.html

    context_object_name = "posts"

    paginate_by = 6

    #filter a post from a certain user, modify the querry set by overidding this method

    def get_queryset(self):

        #get user associated with the username we gonna get from the url. 

        user =get_object_or_404(User, username=self.kwargs.get('username'))

        return Post.objects.filter(author=user).order_by('-date_posted')

class SaleListView(ListView):

    model = Post

class RentListView(ListView):

    model = Post

class BookingListView(ListView):

    model = Post

class PostDetailView(DetailView):

    model = Post

class PostCreateView(LoginRequiredMixin, CreateView):

    model = Post

    fields = ['title','content', 'price', 'propertyImage', 'propertyType', 'area', 'bedrooms', 'baths', 'garages', 

    'location', 'propertyStatus', 'amenities']

    def form_valid(self, form):

        form.instance.author = self.request.user

        return super().form_valid(form)

class PostUpdateView(LoginRequiredMixin, UserPassesTestMixin, UpdateView):

    model = Post

    fields = ['title','content', 'price', 'propertyImage', 'propertyType', 'area', 'bedrooms', 'baths', 'garages', 

    'location', 'propertyStatus', 'amenities']

    def form_valid(self, form):

        form.instance.author = self.request.user

        return super().form_valid(form)

    def test_func(self):

        post = self.get_object()

        if self.request.user == post.author:

            return True

        return False

class PostDeleteView(LoginRequiredMixin, UserPassesTestMixin, DeleteView):

    model = Post

    success_url = '/'

    def test_func(self):

        post = self.get_object()

        if self.request.user == post.author:

            return True

        return False

def about(request):

    return render(request, "maproperty/about.html", {"title": "About"})

def contact(request):

    return render(request, "maproperty/contact_page.html", {"title": "Contact"})

Thank you.
