How do I authenticate with tokens from the remote database?
I am building a REST API that uses 2 postgresql databases: db1 (default) and db2 (remote, read_only). I want to get users from db2 and create a profile for them to store in db1. The custom User and MyToken models are in the db2. Is it possible to do such that Users authenticate using their token from the db2? When I use ObtainAuthToken in my view, it creates new model named Token in db1. -

How to avoid sending error from a specific Python library to sentry?
I'm using django and logging errors to sentry via sentry_sdk. However, I do not want to log errors from specific library. For example, libraries such as elastic apm generate various errors(Like TransportException, ..., etc) depending on the state. import sentry_sdk from elasticapm.transport.exceptions import TransportException sentry_dsk.init( dsn='SENTRY_DSN', ignore_errors=[ TransportException() ] ) The example above is how to write down a specific error and ignore it. Is there a way to ignore errors that occur in a specific library other than this way? -

How to use 2 engines with the same database in Django?
Note: This question is NOT about using 2 databases. So I have been using timescaledb with my django project and my DATABASE portion in my settings.py file is something like this: DATABASES = { 'default': { 'ENGINE': 'timescale.db.backends.postgresql', 'NAME': os.getenv('DB_NAME'), 'USER' : os.getenv('DB_USER'), 'PASSWORD' : os.getenv('DB_PASSWORD'), 'HOST' : os.getenv('DB_HOST'), 'PORT' : os.getenv('DB_PORT'), }, } Now, I want to use postigs with the same database. Under the hood, i can just install the postgis extension to postgres but how should i configure the settings in django? All the documentation of using postgis suggests to use different settings for the 'ENGINE' property, but i have to use timescale too. This article shows it is possible to use both with single DB. But I am just not sure how to do it with django? -

django fileuploader chunk method not working as expected
the Django chunks method on the fileuploader handler accepts chunk_size with this desc in the source code "" Read the file and yield chunks of ``chunk_size`` bytes (defaults to ``File.DEFAULT_CHUNK_SIZE``). """ so i have this view function, def simple_upload(request): if request.method == 'POST' and request.FILES['image']: file = request.FILES['image'] print(sys.getsizeof(file)) chunk_size = 0 dd = list(file.chunks(chunk_size=20000)) print(len(dd[0])) // this gives me some figures like the size of the image print('...') for chunk in list(file.chunks(chunk_size=10000)): chunk_size += sys.getsizeof(chunk) print(chunk_size) return redirect('index') return render(request, 'upload.html') generally, my expectation is that if the image is 50000bytes and i choose a chunk_size of 10000 the length of the generator should be 5. i dont know if i am missing something. -
How do i provide a default image for a django project
In my project, I want users to be able to create a post without an image and if they create it, the default dummy image would be there rather than it Beign blank In my models.py related_image = models.ImageField(default='defaultimg.jpg', upload_to='images/’, null=True) Now if I create a post in the admin section, it would put the default image but if I create it from the users point of view(the form), it does not upload or use the default image forms.py class BlogPostForm(forms.ModelForm): related_image = forms.ImageField(label='', required=False) views.py def uploadPost(request): form = BlogPostForm() if request.method == 'POST': form = BlogPostForm(request.POST, request.FILES) if form.is_valid(): form.save() return redirect('home') The problem is that when a user create a post, the related image would be empty but from the admin section, the default image would show. I want the default image when a user don't provide an image to be 'defaultimg.jpg' Thanks for your contribution -

SearchFilter for multiple models -- Django
Using Django 3.2 with Restframework. I'm trying for search filter and create a API with restframework which would output the searched term with its whole object. I had a little success on that with official doc. But from that I can only search in a single Model and not as globally. I found a blog on how to use multiple Models together? I tried for following from that: Views.py class GlobalSearchList(generics.ListAPIView): serializer_class = GlobalSearchSerializer def get_queryset(self): query = self.request.query_params.get('query', None) users = MasterUser.objects.filter(Q(firstname__icontains=query) | Q(lastname__icontains=query) | Q(email__icontains=query) | Q(category__icontains=query)) webinar = MasterWebinar.objects.filter(Q(host__icontains=query) | Q(title__icontains=query)) section = ResourceSection.objects.filter(Q(resource_name__icontains=query)) item = SectionItem.objects.filter(Q(item_title__icontains=query)) all_results = list(chain(users,webinar,section,item)) serialize_obj = serializers.serialize('json',all_results) print(serialize_obj) #Json response is printed in console return JsonResponse(json.loads(serialize_obj), safe=False) #nothing as output In here, while printing the output it does print a json object, but doesn't return anything as output.

DRF: How to access "context" inside custom DecimalField class?
I am subclassing the DecimalField class from Django RestFramework and need to access context. Formatting for decimal fields includes settings that are user-selectable, so I need to access the user object (which, I assume, should be inside context) inside the to_representation() method. Via debug, I've looked at all properties of self inside my CustomDecimalField class, but, of course, I can't see class methods, so I don't know if there's an appropriate "get" method to get context. I've tried self.context (as a property), self.get_context(), and self.getcontext(), but none worked. I found this announcement re: require_context: https://www.django-rest-framework.org/community/3.11-announcement/ ...but it seems to be valid only for validation and default value methods. This seems like such a simple thing; hard to believe it is so difficult. -

submit form with multiple images
User are able to create posts via a model form. I am attempting to add a feature so once the post is created they can go on the post an and upload multiple images, but I am having some issues implementing it properly. forms.py class PostImagesForm(ModelForm): class Meta: model = PostImages fields = ('images',) widgets = { 'images': forms.ClearableFileInput(attrs={'multiple': True}), } When the user uploads an image I would receive the error 'PostImages' object is not iterable and only one image would get uploaded to the database views.py def DetailPostView(request, pk): model = Post post = Post.objects.get(pk=pk) formImages = PostImagesForm if request.method == 'POST': formImages = PostImagesForm(request.POST, request.FILES) if formImages.is_valid(): formImages = formImages.save(commit=False) formImages.post = Post.objects.get(pk=pk) formImages.save() else: print(formImages.errors) context = { 'post':post, 'formImages':formImages, } return render(request, 'blog/post_detail.html', context) html <div class="content-section"> <form method="post" enctype="multipart/form-data" novalidate> {% csrf_token %} <fieldset class="form-group"> <legend class="border-bottom mb-4">Testing image upload</legend> {{ formImages|crispy }} </fieldset> <div class="form-group"> <button class="btn btn-outline-info" type="submit">Post</button> </div> </form> I figured the issue was because I was only having the form submit once and it needs to submit once for each image (I could be completely wrong) Where I am currently stuck is attempting to setup a loop. I figured the … -
Django Rest Framework - How to create a custom serializer for GoogleSheets
I have some data on a Google Sheet that I'd like to serialize. I've been working on using a Django server to create a REST API that makes it easy for other apps to use. My use case is that we have several different Google Sheet Documents with data about devices we want to serialize. Python has a lot of neat libraries, like SheetFu, that basically do what we want, so I'd like to integrate that functionality with a REST API to do things like search, filter, etc. I did find a Django app, django-gsheets that combined with the Django-Rest-Framework does almost what I want, but it looks like models are fixed to a single Google Sheet Document - I need to be able to work with, and add multiple documents. I can use SheetFu to write a serializer, but I'm not sure how to integrate that with Django, and it's REST framework - can anyone point me in the right direction for this? Thanks! -
