Getting "TypeError: Object of type IFDRational is not JSON serializable" while trying to json.dumps EXIF info
I'm trying to extract EXIF information from an image and store it as a JSONField. It works well for some image types but not for others. Below my code: image_open = Image.open(self.image) image_open.verify() image_getexif = image_open.getexif() if image_getexif: exif = { ExifTags.TAGS[k]: v for k, v in image_getexif.items() if k in ExifTags.TAGS and type(v) is not bytes] } print(json.dumps(exif, indent=4)) I'm getting TypeError: Object of type IFDRational is not JSON serializable when trying to json.dumps(). When dumping the exif dict I notice it is pretty standard so not sure what this is about. {'ResolutionUnit': 2, 'ExifOffset': 204, 'Make': 'Apple', 'Model': 'iPhone 13', 'Software': '15.3.1', 'Orientation': 1, 'DateTime': '2022:03:04 17:35:15', 'XResolution': 72.0, 'YResolution': 72.0, 'HostComputer': 'iPhone 13'} -
Django - Link search bar with autocomplete to item detail page as a result of the search
I have a search bar with autocomplete but I don't know how to link it to the search bar action. Once the user selects one of the items from the autocomplete list, I want to move to the detail.html of that item (using the slug). How do I nest the autocomplete function into the search function? Right now I have a search function which takes the term searched, creates a list of potential item candidates with their url and shows them in the following search_result.html. I want to avoid this step and go straight from the search bar with autocomplete to the detail page of the item. See below the functions. Any ideas on how to do this? Sorry if this is too basic :/ def search(request): if request.method == "POST": searched = request.POST['keyword'] search_vector = SearchVector("descr") search_query = SearchQuery(searched) item = Object.objects.annotate(search=search_vector, rank=SearchRank( search_vector, search_query)).filter(search=search_query).order_by("text_len","-rank") return render(request, 'search_result.html', {'searched':searched, 'item':item}) else: return render(request, 'home.html', {}) def autocomplete(request): if 'term' in request.GET: search_vector = SearchVector("descr") search_query = SearchQuery(request.GET['term']) qs = item = Object.objects.annotate(search=search_vector, rank=SearchRank( search_vector, search_query)).filter(search=search_query).order_by("text_len","-rank") titles = list() # source at the autocomplete in the JQuery expects an url with a list of potential items. for i in qs: … -

How to combine AND and OR in DRF permission_classes decorator?
Before executing a view I would like to verify multiple permissions within the permission_classes decorator, by checking permissions with AND and OR operators. My problem is that IsUserInstance isn't checked in the example bellow, and when I replace & by and then both permission into the parenthesis are not checked.

Django 4 REST framework JSON POST request filter
I have this API where I need to filter some data. My user will pass a JSON containing several instances that I need to return to them if there existis or not on my database. But I don't know how I can make Django 4 make several POST requests within the same JSON (I guess since they would be only getting information this would be several "GET" requests, but I need to make them in a POST). Thoughts on how should I do it? I don't even know how to start. For example, the POST request could be: [ { "name": "media1" }, { "name": "media2" }, { "name": "media3" } ] And if I had medias 1 and 3 but not 2, the API would return the following: [ { "id": 0, "name": "media1" }, { None }, { "id": 1, "name": "media3" } ] This is my current viewset. I have implemented a filter that works only for one GET request at a time: class MediasViewSet(viewsets.ModelViewSet): queryset = Media.objects.all().order_by('name') serializer_class = MediaSerializer authentication_classes = [JWTAuthentication] permission_classes = [IsAuthenticated] def get_queryset(self, *args, **kwargs): print(self.request) queryset = super().get_queryset() if(self.request.data.__contains__("name")): query = self.request.data['name'] if query: queryset = Media.objects.filter(name=query) return queryset This … -

Azure Database for PostgreSQL flexible server Slow with Django
Am using Django to connect to Azure Database for PostgreSQL flexible server but it's very slow, below are the specs of the server : https://i.stack.imgur.com/DnV2y.png As you can see above, the specs are high, but the performance isn't better, in postman when I was hitting to get data it took 34.5 seconds, this is way too much to wait. In my Django code, I tried my best to optimize the queries, and on Heroku, it was super fast, however here on Azure it's extremely slow, what could be done to improve the speed of the server?

In Django, can I use a variable passed to a function in order to access and attribute of a model?
I'm trying to create a custom function where one of the variables passed is the name of an attribute of a model. I'm doing this to try to access the underlying value. def tabsums(entity_object, year_object, columntitle): curassetobject = BSAccountType.objects.get(name = "Current asset", company = entity_object) curassetsum = BSSum.objects.get(Q(company = entity_object) & Q(year = year_object) & Q(account_type = curassetobject)).columntitle Essentially, I want columntitle to be a string that matches the model field name so I'm trying to pass the variable as the attribute name to access the underlying value. It's not working as Django/python is looking for the attribute "columntitle" which does not exist, rather than looking to the underlying string. Is there a syntax I can use that will allow Django to utilize the underlying string value that is passed? Thank you very much. -

Django problem updating date field when updating a record
I have a problem when I try to update a field named date_updated. My intention with the field is that every time a record is updated, the date_updated field of that record should be updated by the date the change is made. That field and one other field I have inside a Base class and then in each of the models I inherit that class to repeat the fields. class Base(models.Model): ... date_updated = models.DateTimeField(auto_now=True) def save(self, *args, **kwargs): self.date_updated = django.timezone.now() super(Base, self).save(*args, **kwargs) class Meta: abstract = True class OtherClass(Base): ... My intention is that when I update any record in the OtherClass, its date_updated field will be updated. I also tried adding the overwrite of the save method in the OtherClass, but the result is the same. The date is kept after I make the change. I am making the change with .update(**data_to_update) -

Apache2 not loading Django settings.py file properly
I am currently facing an issue where making any changes in settings.py file is not reflecting properly in my project. I have tried deleting the .conf file, adding it again, enabling it and reloading the apache2 server. But somehow it still does not work. I have an issue with CORS in Django, I made changes to correct it by allowing certain origins to make cross-origin requests: CORS_ALLOWED_ORIGINS = ['www.test.domain',...] So I tested it by running the Django server manually using python runserver 0.0.0.0:8000 and it is working fine, not getting any CORS issues But when I reload the apache2 server or even in this case, make a completely new .conf file and run it via apache2 - it still somehow does not recognize the changes and keeps giving me CORS errors. I am confused as to what is making this happen - to not reflect any newly made changes. The problem is, now I am not able to reflect these changes with a new configuration as well. So there is no way for me to keep this webserver running without getting CORS errors. NOTE: Apache has all the required accesses to my Django project - it can access settings.py without … -
How to get child model having one to one relation with default User model of Django?
I created a model having one to one relation with default User model to extend it for providing some permission for tabs in my website. Now I want to not show the tab options to the users not having permissions to access them. user permission model: from django.contrib.auth.models import User class userpermissions(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) Checking whether the user has permission or not I created a function which is supposed to get the userpermission model instance of the logged in user. For which I used the following code -> def check(user): up = User.userpermissions_set.get(id=user.id) Now when user logs in the login function will call this check function and redirect to the tab that the user can access and also send the up variable containing all the permissions of the user so that the Navbar templet can hide those tabs which the user has no access to. Now the problem that I am facing is when I run the server it shows this error -> AttributeError at / type object 'User' has no attribute 'userpermissions_set' I saw on YouTube that to get the instance of child model (I don't know what to call it..) we need to use it's …
