Django queryset checking existence having unexpected behavior
I have a model like this class Student(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) archived = models.BooleanField(default=False) class Meta: constraints = [ UniqueConstraint( fields=["first_name", "last_name"], condition=Q(archived=False), name="unique_user" ) ] and code like below d = {"first_name": "John", "last_name": "Doe"} students = Student.objects.filter(first_name=d.get("first_name"), last_name=d.get("last_name")) for student in students: """Doing some stuff here""" pass if not students: Student.objects.create(first_name=d.get("first_name"), last_name=d.get("last_name")) I am getting an integrity error from the last line where I call objects.create duplicate key value violates unique constraint "unique_user" DETAIL: Key (first_name, last_name) In the objects.filter() I have two fields that are part of the unique constraint, and I am using the same queryset before the objects.create is called, so this error should not happen unless something going wrong with the queryset. This code is working without issues most of the time. Only once this error was raised. Any idea what is going on ? One possibility is that between the filter query and the create query the object was created and the integrity error was raised from create query. But that was not the case. I checked the db, there was nothing created. Infact there was already data which was created hours before matching these conditions. So the filter query … -
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? For more information on Django this is the view.py of the endpoint: @method_decorator(cache_page(60 * 60 * 4), name='get') @method_decorator(vary_on_cookie, name='get') class PostList(generics.ListCreateAPIView): """Blog post lists""" queryset = Post.objects.filter(status=APPROVED).select_related( "owner", "grade_level", "feedback").prefetch_related( "bookmarks", "likes", "comments", "tags", "tags__following").prefetch_related("address_views") serializer_class = serializers.PostSerializer authentication_classes = (JWTAuthentication,) permission_classes = (PostsProtectOrReadOnly, IsMentorOnly) def filter_queryset(self, queryset): ordering = self.request.GET.get("order_by", None) author = self.request.GET.get("author", None) search = self.request.GET.get("search", None) tag = self.request.GET.get("tag", None) # filter queryset with filter_backends 🖟 queryset = super().filter_queryset(queryset) if ordering == 'blog_views': queryset = queryset.annotate( address_views_count=Count('address_views')).order_by( '-address_views_count') if author: queryset = queryset.filter(owner__email=author).select_related( "owner", "grade_level", "feedback").prefetch_related( "bookmarks", "likes", "comments", "tags", "tags__following").prefetch_related("address_views") if tag: queryset = queryset.filter( tags__name__icontains=tag).select_related( "owner", "grade_level", … -
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. -
Pass list dict as params in axios react
I am building a react app. I am trying send list dict as params in axios. I am using Django rest framework as backend and It is showing [] or None every times I send request. App.js function App() { const [currentState, setCurrentState] = useState([{"name": "First", "id": 100}, {"name": "Second", "id": 200},]) const sendRequest = () => { axios.get("/api/", {params: {state: currentState}).then((res) => { console.log(res); }) } return ( <> <b onClick={sendRequest}>Send request</b> </> ) } I am trying to send the whole list dict to backend as params like. [{"name": "First", "id": 100}, {"name": "Second", "id": 200}] But it showing none. in backend I am accessing like views.py class Api(APIView): def get(self, request, *args, **kwargs): data = self.request.query_params.get("state") print(data) return Response({"good"}) I have also tried using paramsSerializer in axios for serialization like :- const sendRequest = () => { axios.get("/api/", { params: { state: currentState }, paramsSerializer: params => { return qs.stringify(params, {arrayFormat: "repeat"}) }, ).then((res) => { console.log(res); }) } but it is still not working. Tried also {arrayFormat: "brackets"}. Any help would be much Appreciated. Thank You -
Is Django db_index helpful in text search queries?
I've a similar model in a Django project: from django.db import models class Book(models.Model): title = models.CharField(verbose_name='Title', max_length=255, db_index=True) authors = models.CharField(verbose_name='Authors', max_length=255, db_index=True) date = models.DateField(verbose_name='Date', db_index=True) In the views I need to do a full text search query like the following: books = Book.objects.filter(Q(title__icontains=query) | Q(authors__icontains=query)) Is the db_index=True actually helping the performances of my query or not? -
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 … -

Django - How to use delete() in ManyToMany relationships to only delete a single relationship
I have a model Voucher that can be allocated to several users. I used a M2M relationship for it. I want, in the template, the possibility to delete the voucher allocated to the logged in user, and the logged in user only (not all relationships). The problem I have is that the current model deletes the entire model for all users, instead of the single user requesting "delete". The alternative would obvioulsy be to simply create a model Voucher on a ForeignKey, but something tells I can probably do it with a M2M in the views. Is there a way to focus my delete function specific to the user? In the example below, I tried to filter based on user.request which is not working. Looking at the data inside the model, users IDs are listed. Is it not what request.user does? models class Voucher(models.Model): user = models.ManyToManyField(User, blank=True) views def delete_voucher(request, voucher_id): voucher = Voucher.objects.filter(pk=voucher_id).filter(user=request.user) voucher.delete() return redirect('account') template <a class="button3 btn-block mybtn tx-tfm" href="{% url 'delete-voucher' voucher.id %}">Delete</a> url path('delete_voucher/<voucher_id>', views.delete_voucher, name='delete-voucher'), -

How to change the date of time instance using python?
I have start_time variable that stores a time string. start_time = '2022-12-21 22:00:00' Now Using python i want to change the date of start time to start_time = '2022-12-28 22:00:00' I have done this with very ugly approach. Please tell me easy and best way to do that. I tried with following code. #its not string its time instance replacing_date = 2022-12-28 00:00:00 #converting time into string replacing_date = datetime.strptime(replacing_date,'%Y-%m-%d %H:%M:%S') replacing_date =replacing_date.split(" ") start_time = start_time.split(" ") start_time = datetime.strptime(replacing_date[0]+start_time[1],'%Y-%m-%d %H:%M:%S') Basically i have to change date on many places. It doesn't seems to be good thing in that case. and it can break if time string format changes. i can also break if the years end. for example date change to. start_time = '2023-01-01 22:00:00' -
