Receiving data in the serializer from a related model by relation_name in DRF
I have 2 models class News(models.Model) title = models.CharField(max_length=100, null=False) text = models.TextField(null=False) class NewsImages(models.Model) news = models.ForeignKey( to=News, null=True, on_delete=models.CASCADE, related_name='images' ) image = models.FileField( upload_to="news/img/%Y/%m/%d", null=False, ) I need serialize model with related images. I try do it use nested serializers: class NewsImageSerializer(serializers.ModelSerializer): image = Base64ImageField() class Meta: model = NewsImage fields = '__all__' class NewsSerializer(serializers.ModelSerializer): images = NewsImageSerializer(many=True) class Meta: model = News fields = '__all__' But got error: AttributeError at /api/v1/news/ Got AttributeError when attempting to get a value for field `images` on serializer `NewsSerializer`. The serializer field might be named incorrectly and not match any attribute or key on the `News` instance. Original exception text was: 'News' object has no attribute 'images'. As I understand from similar questions, it should work exactly like this via related_name. Why doesn't this work for me, what am I doing wrong? -
Can I add a global query parameter to all methods on all Viewset endpoints in Django Rest Framework?
For some purpose I need to add a query parameter to all DRF API viewset method calls and I need to be able to supply from Swagger. In FastAPI it is easily done with a dependency injection on global level like this: async def code(code: Code = None): """Dependency to add code query parameter to all endpoints""" pass fastapi_app = FastAPI(docs_url=None, title="SAF2 API", dependencies=[Depends(code)]) But I have been struggling with custom filters and middleware in Django, but I am not getting it to work. Filters seem to only apply to GET methods and I don't know a lot about middleware to write one myself. I can put it manually on all endpoints with decorators and stuff but that is all very ugly. My viewset looks like this: class CustomerViewSet(viewsets.ModelViewSet): authentication_classes = [SessionAuthentication, BasicAuthentication] permission_classes = [IsAuthenticated] serializer_class = CustomerSerializer queryset = Customer.objects.all() filter_backends = [ filters.SearchFilter, filters.OrderingFilter, django_filters.rest_framework.DjangoFilterBackend, ] search_fields = ["full_name", "name", "status"] filterset_fields = ["full_name", "name", "status"] Any help or reference to documentation would be appreciated greatly! A nice bonus would be to add custom headers to all requests. -
Multiple Django projects independent from one another - DB migrations writing to wrong DB
I have been working with Django for about three years now and have developed a couple business grade apps which are deployed and doing great. The other day, I created a new project with a new database, etc. I built out the initial models and migrated them to the proper database. However, subsequent migrations are going to a database I built for another app entirely. The two databases aren't on the same host, don't have similar names - they have nothing in common. How is this possible? Is there some connection cache I need to clear? I haven't even had any of the other projects open or running locally- nothing. I'm baffled. -
Implementing Kerberos and LDAP in Django
firstly, i'm very new to Django. I have developed a Django app that includes a ticket system. Users should only see their own tickets. Now this self service system should be connected to the Microsoft account to enable a single sign on. To do this, the Django app must first be connected to Kerberos and then authenticated using LDAP. However, after extensive searching I cannot find any comprehensible documentation that explains the procedure. That's why I'm turning to you with the hope that someone can help me. Many thanks in advance Pablo I tried using the Dkango Documentation and various other "Docs" which were either outdated or incomplete(like the official django documentation) also other helpful threads in here are outdated. -
Custom django model field to upload a file to an external file/cloud host
I want to have a custom model field for file upload to an external hoster, which I can just add to a model. It is important, that I don`t have to edit the admin form, to be form independent. File should not be saved in django's media system. It should directly be uploaded to a file hoster. The hoster than returns file id. This id should be saved to the field. I managed to do this with the following code. But this can`t the best solution. It is too much and to strange code. Let's not talk about dropbox or the dropbox api, it`s just an example. Could be every other cloud/file hoster. My question is about such fields with file upload in django, not about the hoster. I know that there is django-storages and similar packages, but I do not want to use it for reasons. What would be a better solution? class DropboxFileIdWidget(AdminFileWidget): def value_from_datadict(self, data, files, name): uploaded_file = super().value_from_datadict(data, files, name) if uploaded_file: # Determine the path for the temporary file temp_dir = tempfile.gettempdir() temp_file_path = os.path.join(temp_dir, uploaded_file.name) # Check if a file with the same name already exists, and delete it if os.path.exists(temp_file_path): os.remove(temp_file_path) # … -

In Wagtail, how to deal with singleton pages?
I am developing a wagtail website. There are some pages that have specific design that will exist on exactly one page (e.g. "who are we" with a list of pictures and bio, "how does it work" which integrates some very specific charts in a very specific way, the home page…). Currently, for those pages, I am creating one model/template per page, but it's not perfect: The page has no dynamic content and the url can be chosen ahead of time. I could use a simple static html asset, it won't have the right url (it would be something like domain.com/static/who-are-we.html instead of domain.com/who-are-we) Non-technical editors are confused (why can I create more than 1 "who are we" page?) Since the page is a singleton, referring to it in other pages should be easy. But currently I have to add a field to other pages model and choose the page every time. That's a bummer since I know that there exist one and only one page "who are we", so I'd like to directly integrate it in the template and skip a field in my models. Is there an idiomatic way to deal with this situation in Wagtail? -

what will happend if a user submits the old form without refreshing the page after I've made changes to the Django form
I have made some changes to the form of my Django website, for example: some values of thoes checkbox were changed. A user already opened the form before my changes, and he submited the form after making some changes. What will happened? In my local machine with Django 2.2 and Chrome 116.0.5845.110, the form page was refreshed after I clicked the Save button. Thanks! You can ignore the bellowing cause it could be related with my codes. (The refreshed form is not expected, which contains the new changes but a little different. If I open the url of the form page to a new tab, everything works fine) -

Gradual Disk Usage Increase in Django/OpenLiteSpeed on Ubuntu - Seeking Guidance on Identifying and Resolving the Issue

How do I create an emptry LineString in GeoDjango
I am having a problem with the latest version of the GeoDjango extensions in Django version 4.2.6 when I create an empty LineString. The same code is behaving differently than it did in version 4.0.10. The default seems to have switched to creating a Geos object with 3-dimensions rather than the previous 2-dimensions. The following code returns a different WKT object depending on the version of Django I am using. from django.contrib.gis.geos import LineString ls = LineString() ls.wkt This is returning a 3-dimensional object "LINESTRING Z EMPTY". Running exactly the same code on Django 4.0.10 creates a 2-dimension object "LINESTRING EMPTY". Is there anything obvious I am doing wrong? I am also running a slightly newer version of geos-3.12.0 versus 3.11.2 but I cannot see anything is both sets of release notes that describe this change in behaviour. -
JavaScrip Gmail API code not working on Django template

Im trying to migrate the javascript example from the Google docs website, and migrate it to my django proyect, yet doesnt work, and when trying to use the EXACT SAME CODE with the server initialization provided in the docs, it works, why is not working the Gmail API on my django project??

Request Issue With Django On AWS

I am receiving the below error from the web.stdout logs, but I am not sure if this is why its failing, or what is going on. https://i.stack.imgur.com/c2zPq.png The project is programmed in python with a Django front end, and Elastic Beanstalk is being used for deployment. The project can be found here: https://github.com/Nessbound/asop_chatbot/tree/stack-overflow I'm not exactly sure where the error is, so I am posting the whole project. Thanks in advance for any help! -
How would I handle another POST request on my site
Hello in my login site I have a form that sends a POST request on submit. this is how I handle the forms POST request in my view def SignUp(request): if request.method == 'POST': stuff goes here else: form = SignUpForm() return render(request, "index.html", {"form": form}) now in my javascript i want to add another POST request that'll check if the current username within a certain is already taken. I made it and sent the POST to my current view where both this POST request will be handled along with the form POST request. what ends up happening is that SignUp() keeps handling both the POST requests. How do I handle two POST requests in one view? Is there a better way to do all of this? (i would preferably want to stay on this url) tried to read about any way to differentiate between POST requests but found nothing. (i started learning django just a few days ago and im completely lost trying to make this work) -
Django / Pytest / Splinter : IntegrityError duplicate key in test only
I know it's a very common problem and I read a lot of similar questions. But I can't find any solution, so, here I am with the 987th question on Stackoverflow about a Django Integrity error. I'm starting a Django project with a Postgres db to learn about the framework. I did the classic Profile creation for users, automated with a post_save signal. Here is the model: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) description = models.TextField(max_length=280, blank=True) contacts = models.ManyToManyField( "self", symmetrical=True, blank=True ) And this is the signal that goes with it : def create_profile(sender, instance, created, **kwargs): if created: user_profile = Profile(user=instance) user_profile.save() post_save.connect(create_profile, sender=User, dispatch_uid="profile_creation") The project is just starting, and for now I only create users in the admin view. With the post_save signal, it's supposed to create a Profile with the same form. Here is the admin setup : class ProfileInline(admin.StackedInline): model = Profile class UserAdmin(admin.ModelAdmin): model = User list_display = ["username", "is_superuser"] fields = ["username", "is_superuser"] inlines = [ProfileInline] I'm using pytest and Splinter for my test, and this is the integration test that don't work : @pytest.mark.django_db class TestAdminPage: def test_profile_creation_from_admin(self, browser, admin_user): browser.visit('/admin/login/') username_field = browser.find_by_css('form input[name="username"]') password_field = browser.find_by_css('form input[name="password"]') username_field.fill(admin_user.username) …
