How can I optimize response time in this python code? (django)
The get_assets method obtains a list of assets from the database and for each item in the list calls the __build_asset_response method to build a response in dictionary format. However, when there are many assets, the time to do the build_asset_response is very high. Does anyone know a method to optimize the time? def get_assets(user, data): if data.get('asset_id'): assets = Asset.objects.filter(pk__in=data['asset_id']) return [__build_asset_response(asset) for asset in assets] assets = Asset.objects.filter(QueryHelper.filter_by_rol(user)) return [__build_asset_response(asset) for asset in assets] This is the buil_asset_response private method: def __build_asset_response(asset): asset_dict = { 'id': asset.pk, 'name': asset.name, 'accessibility': manage_accessibility.build_accessibility_type_response(asset.accessibility), 'folder': "", 'user_id': { 'id': asset.user.id, 'name': str(asset.user) }, 'organization': { 'id': asset.idOrganization.id, 'name': str(asset.idOrganization), }, 'asset_type_id': asset.idAssetType and __build_asset_type_response(asset.idAssetType) or {}, 'file': settings.MEDIA_URL + asset.archivo.name, 'tag_ids': [tag.name for tag in asset.tag_ids.all()], 'lastModified': timezone.localtime(asset.last_modified_date).strftime("%Y-%m-%d %H:%M:%S"), 'used_in_publication': asset.used_in_publication } if asset.idFolder: folder = manage_folder.build_folder_response(asset.idFolder) else: folder = '' asset_dict.update({ 'folder': folder, }) return asset_dict -

Detected path traversal attempt - Django/Heroku(Bucketeer)
I'm getting this error when trying to upload using FileField. I'm using Bucketeer on Heroku to upload to an AWS bucket. I've seen a few threads on this issue but haven't been able to figure it out. The file upload view: class UploadTicketAttachment(APIView): permission_classes = [] parser_classes = (MultiPartParser, FormParser) def post(self, request, format=None): user = request.user serializer = AttachmentSerialiazer(data=request.data) if serializer.is_valid(raise_exception=True): serializer.validated_data['uploaded_by'] = user serializer.save() return Response(serializer.data['id']) else: return Response(f'{serializer.errors}, attachment upload failed') The model: class Attachment(models.Model): file = models.FileField(upload_to="/ticket_attachments", blank=True, null=True) created_on = models.CharField(max_length=20, null=True) uploaded_by = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=True, related_name="uploaded_by") parent_ticket = models.ForeignKey(Ticket, on_delete=models.CASCADE, null=True, related_name="attachment") def __str__(self): return self.file.name For the settings/bucketeer configuration I followed which uses django-storages: https://dev.to/heroku/properly-managing-django-media-static-files-on-heroku-o2l I don't think the issue is on that end since I set it up the exact same way in another project and it works fine with the only difference being that the other project uses ImageField instead of FileField. Django version is 4.0.2. Any ideas? Thanks -

Best practice for Python typing out of dictionary (self.fields type in Django ModelForm)
I have a form like this class MerchantBrandsForm(forms.Form): brands = forms.ModelChoiceField(required=True, queryset=None) def __init__(self: merchant: Merchant): self.fields['brands'].queryset = merchant.brands.all() But I have an error with mypy with the queryset as fields has a type Dict[str, Field], which cause error: "Field" has no attribute "queryset". I know I can cast the fields using cast or ignore the typing, but I don't think this is a clean solution. What is the best way to assign brands queryset without ignoring the type or using cast function? -

Is it possible to return the display name of a choice in Django?
So when you make choices for a form/model you do this: EXP_CHOICES = ( ('1ST','First'), ('2ND','Second'), ....... ('XXX','YYY'), ) # where XXX is the value stored in the database and YYY is what you see in a form. This also applies to the queries, so when you have the mentioned choices and select one, do a query on the model and it returns '1ST'/'2ND'/'XXX'. But what if you want to display the YYY instead? So we know that '1ST' is 'First', but we want to make it user readable. Is there a way to access that EXP_CHOICES and write out the YYY tied to them, or you must make an if&else/selector to be like {% if data.chosen == '1ST'%} First {% elif ... %} ... {% endif %} -

What type of database replication is used by Digital Ocean's read-only nodes?
I'm working on two Django projects that need to share a PostgreSQL database, a database which needs to be replicated for read-only operation. The reason is that one of the projects mostly performs write operations while the other performs read operations. To achieve this, I'm considering Digital Ocean's read-only nodes. The question that comes to my mind how long it takes to propagate a write operation in the primary sever to the read-only server located in the same datacenter, so that future read requests return consistent results. And, more importantly, is the replication synchronous or asynchronous ? Some solutions are synchronous, meaning that a data-modifying transaction is not considered committed until all servers have committed the transaction. This guarantees that a failover will not lose any data and that all load-balanced servers will return consistent results no matter which server is queried. In contrast, asynchronous solutions allow some delay between the time of a commit and its propagation to the other servers, opening the possibility that some transactions might be lost in the switch to a backup server, and that load balanced servers might return slightly stale results. Asynchronous communication is used when synchronous would be too slow. https://www.postgresql.org/docs/current/high-availability.html -
Why I am getting django.db.utils.IntegrityError even after removing default=0?
I am new to Django. I was working on a project whose one of the database tables has a recursive foreignkey. I am sharing that table here. class Categories(models.Model): name = models.CharField(max_length=25) slug = models.CharField(max_length=25) parent = models.ForeignKey("self",on_delete=CASCADE,default=None,blank=True) My database migration did not work when the default was 0. It worked fine when there was null = True. The problem occurred when I removed the null and set default to 0. After having the error, I removed the default=0 and set the null to true.

Sum numbers and group them by the given month, is there a 'best practice'?
I don't know what I messed up. I tried so many methods and solutions and so far this works the best, but the ordering is messy. I want to sum the expenses grouped by the month extracted from the datefield it was given. So far I made this: def index(req): qs = Expense.objects.filter(pom='OUT').annotate(month=TruncMonth('when')).values('month').annotate(total_amount=Sum('amount')) # pom='OUT' -- expense (there are expenses and incomes) return render(req, 'index.html', {'data': qs}) which works perfectly, returns them as "sept. 15.000, aug. 10.000" which is nice! But the last/latest month is always at the bottom so I wanted to give it an order_by, which returns each unique object in the model (so if sept. 15.000 came up as sept.15 10.000 and sept.22 5.000, when they're not summed up but returned/shown separately). What did I mess up? EQ: The mentioned query (without order_by) returns a queryset as of <QuerySet [{'month': datetime.date(2022, 8, 1), 'total_amount': 15000.0}, {'month': datetime.date(2022, 9, 1), 'total_amount': 16000.0}]> by default making it look they all have been recorded at the start of the given month. Drop a reply for further information if I forgot to include something/explained something poorly! -
How to properly import an existing Django project in Eclipse/Pydev?
I cannot figure how to import correctly an existing Django project in Eclipse/Pydev, and I can't find my way in the documentation of Pydev. My question is pretty simple : I have an existing project from a different computer, that I want to migrate on a new one. I installed Eclipse and Pydev on the new machine, and everything seems normal for a new project: I can create a new Django project and run it without issue. I also have been able to import my pre-existing project, but when I run the project, I encounter the following error : Finding files... done. Importing test modules ... Traceback (most recent call last): File "/home/francois/.p2/pool/plugins/org.python.pydev.core_9.3.0.202203051235/pysrc/_pydev_runfiles/pydev_runfiles.py", line 468, in __get_module_from_str mod = __import__(modname) File "/home/francois/eclipse-workspace/Test/Test/urls.py", line 20, in <module> path('', include('myApp.urls')), File "/home/francois/anaconda3/envs/ipaidenv/lib/python3.10/site-packages/django/urls/conf.py", line 34, in include urlconf_module = import_module(urlconf_module) File "/home/francois/anaconda3/envs/ipaidenv/lib/python3.10/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "/home/francois/eclipse-workspace/Test/myApp/urls.py", line 2, in <module> from . import views File "/home/francois/eclipse-workspace/Test/myApp/views.py", line 2, in <module> from myApp.forms import CreateGroupForm, JoinGroupForm File "/home/francois/eclipse-workspace/Test/myApp/forms.py", line 4, in <module> from .models import Group, User File "/home/francois/eclipse-workspace/Test/myApp/models.py", line 2, in <module> from django.contrib.auth.models import AbstractUser File "/home/francois/anaconda3/envs/ipaidenv/lib/python3.10/site-packages/django/contrib/auth/models.py", line 3, in <module> from django.contrib.auth.base_user import AbstractBaseUser, BaseUserManager … -
