Groupby using Django's ORM to get a dictionary of lists from the queryset of model with foreignkey
I have two models, Business and Employee: from django.db import models class Business(models.Model): name = models.CharField(max_length=150) # ... class Employee(models.Model): business = models.ForeignKey( Business, related_name="employees", on_delete=models.CASCADE, ) name = models.CharField(max_length=150) # ... Here's a sample data: Business.objects.create(name="first company") Business.objects.create(name="second company") Employee.objects.create(business_id=1, name="Karol") Employee.objects.create(business_id=1, name="Kathrine") Employee.objects.create(business_id=1, name="Justin") Employee.objects.create(business_id=2, name="Valeria") Employee.objects.create(business_id=2, name="Krista") And I want to get a dictionary of lists, keys being the businesses and values being the list of employees. I can do so using prefetch_related on the Business model. A query like this: businesses = Business.objects.prefetch_related("employees") for b in businesses: print(b.name, '->', list(b.employees.values_list("name", flat=True))) Which gives me this: first company -> ['Karol', 'Kathrine', 'Justin'] second company -> ['Valeria', 'Krista'] And this is exactly what I want and I can construct my dictionary of lists. But the problem is that I only have access to the Employee model. Basically I only have a QuerySet of all Employees and I want to achieve the same result. I figured I could use select_related, because I do need the business objects, but this query: Employee.objects.select_related("business") Gives me this QuerySet: <QuerySet [<Employee: Employee object (1)>, <Employee: Employee object (2)>, <Employee: Employee object (3)>, <Employee: Employee object (4)>, <Employee: Employee object (5)>]> And I don't … -

'cannot write mode RGBA as JPEG' when saving image
I'm getting: OSError at /admin/blog/post/add/ cannot write mode RGBA as JPEG error when uploading an image file other than 'jpeg' with Pillow. This is the function I'm using to resize the image: def resize_image(image, size): """Resizes image""" im = Image.open(image) im.convert('RGB') im.thumbnail(size) thumb_io = BytesIO() im.save(thumb_io, 'JPEG', quality=85) thumbnail = File(thumb_io, name=image.name) return thumbnail Most solutions to this same error seem to be solved by converting to 'RGB', but I'm already doing that in my function except it still keeps giving error when uploading, for example, a .png image. How can I fix it? -

how to add form as data in class-base views?
I used to send form as content in function-base-view and I could use for loop to simply write down fields and values like: {% for x in field %} <p>{{ x.label_tag }} : {{ x.value }} </p> I don't remember whole the way so maybe I wrote it wrong but is there anyway to do this with class-based-views, because when I have many fields its really hard to write them 1by1 -
How to send back a numerical value to Django serialiser to display as JSONResponse?

how to make alert pop up in html while error in django function
I have a function, where if the function has an error in it, a "wrong key" message will pop up in the html. I tried to use messages, but it has a condition that it must use request. because i call this messages inside the function, so there is no request. how can I display the "wrong key" pop up, if the iv cannot be used/wrong? I use try and except, so if it can't be processed, then except runs. here's my function code: def decrypt(cipher_text, key): if len(key) <= key_bytes: for x in range(len(key),key_bytes): key = key + "0" assert len(key) == key_bytes private_key = hashlib.sha256(key.encode("utf-8")).digest() cipher_text = base64.b64decode(cipher_text) try: iv = cipher_text[:16] cipher = AES.new(private_key, AES.MODE_CBC, iv) return unpad(cipher.decrypt(cipher_text[16:]).decode('utf-8')) except: print("WRONG PASSWORD") messages.error(request, 'wrong key!') return redirect('decode') here's my html: {% for message in messages %} <div class="alert alert-warning" role="alert" id="some_flag"> <a class="close" href="#" data-dismiss="alert">×</a> {{message}} </div> {% endfor %} -

Django URLs not updating after slug change
I use Slugify. After making a change in slug for all objects in Entry, slug still shows as old slug. If I refresh obj page, I get a page not found, unless I click "back" and then reopen the obj page, and that is when the obj page will load and new slug will update. Any idea how to fix this? I tried an empty migration and applied obj.save() and obj.refresh_from_db() but no luck. Below is my model, this is what generates my slug field: (My change was removed self.4 and replaced with self.5) class Entry(models.Model) 1 = ... 2 = ... 3 = ... 4 = ... 5 = ... slug = models.SlugField(null=True, unique=True, max_length=300) def save(self, *args, **kwargs): self.slug = slugify(f"{self.1}-{self.2}-{self.3}-{self.5}") return super().save(*args, **kwargs) def get_absolute_url(self): return reverse("page", kwargs={"slug": self.slug}) -

samesite none without secure browser
I'm developing with React and Django. The original plan was to send api requests from the front to the Django server to manage sessions and read data, but it seems that cookies cannot be stored in the browser due to the samesite problem on the localhost used as a test during development. (It works in postman) And when React and Django are run on the server, there is no problem with the session, so samesite=none that can be tested during development, but an environment that does not require secure is required. Try: Use old version firefox Django - check cookies's "SameSite" attribute CSRF_COOKIE_SECURE = True SESSION_COOKIE_SECURE = True CSRF_COOKIE_SAMESITE = 'None' SESSION_COOKIE_SAMESITE = 'None' Use axios proxy https://pypi.org/project/django-samesite-none/ (django middleware) -
