PostgreSQL/Django: target >2 Billion (2.000.000.000) Limit/Advice
I developed an R&D database to store machine time data. From this raw time I calculate/extract statistics. Suggestions/advice is needed regarding data size limits. Setup: Django (Python) backend with PostgreSQL database. Concept: Every machine: stores about 300.000 records split over two tables: index_table and data_table. An index_table contains machine info (setting, labels, operator). The data_table has 7 fields (index*, step*, datetime, value, setpoint, comment, active) where index* is an foreign key to index table and step* an foreign key to measurement settings. Comment field (text) about 30 chars. Workflow: Normally raw data (300.000 records) is uploaded to data_table and statistics are calculated/extracted. Typical user: Zero: Upload and extract datafile to database (index_table, data_table). Every time about 300.000 records in data_table. After that user "initiates calculate statistics". First: "production" report request is to collect statistics (no problems relative small tables). Second: "R&D" report request raw data (300.000 records) and server make some transformations and plots (Plotly) over HTML Status: Currently I uploaded 400 machines. The data_table has 30.000.000 (30 million) records and the database size is: 10Gb. The server is running on a low end workstation. Performance is fine and smooth. And above my expectation (last large database experience 20 years … -
How do I create multiple different types of POST requests in Django that can each be handled in a different way?
In my django project, I have a page which allows users to add a task through clicking a button and entering the details of the task(in a modal window). Users are also able to edit/delete tasks by clicking a button next to each respective task. I've run into the issue of not being able to submit different types of post requests that can handle each operation individually. Here is an image of the page for clarity: User interface I'm not sure how to create two different "types" of POST requests that can handle these two cases. One "type" of POST request for adding a task and another for editing/deleting it. Just for reference, this is what the modal window would look like to add a task: add task Right now this is the URL I want both of them to redirect to when the form is submitted(which is just the original page after the modal window is removed after submission) is: path('team/<str:team>/', views.team_view) This is the team_view function currently: def team_view(request, team): connection.connect() team_url = team[4:] if(team[4] == '1'): team_num = team[4:] else: team_num = team[5] tasks = Task.objects.filter(team_id=team_num) context = { 'task_list' : tasks, 'team_id' : team_num, 'team_id_url': team_url … -
django ajax send data from view to template and display these value
I would like to know how I can display data in django template like {{data}} from ajax post request. This is how I handled the ajax request in the views let say that I have a context data dict context = {'value1': Model.objects.filter(field=value), 'value2': request.POST.get('valu') } if request.is_ajax(): I would like to have the same data and display data into the template when the request is ajax return JsonResponse(context) I would like to display the same data in template as {{value1}} {{value2}} but when its ajax request the data is not displayed anymore.

Django: Setting default value of model field to an attribute of a OneToOneField of a ForeignKey object
I am trying to set Report.branch to Report.user.profile.branch, however I receive the error: AttributeError: 'ForeignKey' object has no attribute 'profile". I understand this is happening because user is a ForeignKey object and not an actual User object, but I am not sure how to resolve it. Here is the code I am using: accounts/models.py from django.contrib.auth.models import User from django.db import models from django.db.models.signals import post_save from django.dispatch import receiver class Branch(models.Model): id = models.AutoField(primary_key=True) manager = models.ForeignKey(User, on_delete=models.DO_NOTHING) address = models.CharField(max_length=50) city = models.CharField(max_length=30) def __str__(self): return self.city class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) branch = models.ForeignKey(Branch, on_delete=models.DO_NOTHING) def __str__(self): return self.user.username @receiver(post_save, sender=User) def create_user_profile(sender, instance, created, **kwargs): ''' Creates Profile when User is created ''' if created: Profile.objects.create(user=instance) @receiver(post_save, sender=User) def save_user_profile(sender, instance, **kwargs): ''' Saves Profile when User is saved ''' instance.profile.save() otherapp/models.py from django.db import models from django.contrib.auth.models import User from django.utils import timezone from accounts.models import Branch class Report(models.Model): user = models.ForeignKey(User, on_delete=models.DO_NOTHING) branch = models.ForeignKey(Branch, default=user.profile.branch) report_num = models.AutoField(primary_key=True) If you have anything to point me in the right direction that would be appreciated. -
django form.save() leads to encoding errors
When saving German Umlaute to my database I end up with the unicode representation of the letters. Saving the word Nüsse in my postgrey database reads as N\u00fcsse. The form is simply saved by: class ProductUpdateView(UpdateView): template_name = ... form_class = ProductForm def form_valid(self, form, *args, **kwargs): try: form.save() except IntegrityError: return self.form_invalid(form) return HttpResponse(...) Product(models.Model): data = models.JSONField() number = models.PositiveIntegerField() So I thought I need a customized JSON field, whereas I altered my code: class myJSONField(models.JSONField): def get_prep_value(self, value): if value is None: return value return json.dumps(value, ensure_ascii = False) class Product(models.Model): data = models.myJSONField() number = models.PositiveIntegerField() but this lead to a database entry that read "{\"name\": \"Nüsse\" ...}" where all of the '"' where escaped by '\'. I evaluated the problem using SQLite and the error prevails. My idea would be to use the form's clean method: def clean(self, *args, **kwargs): cleaned_data = super().clean() for key in cleaned_data.keys(): cleaned_data[key] = encoded(cleaned_data[key]) return cleaned_data but I am unsure on how encoded should look like here, or if I should still use the myJSONFieldapproach. The database collation says its utf8mb4_general_ci: -

ImportError: cannot import name 'name' from partially initialized module 'app.models' [closed]
У меня два приложения Users и Main для работы с пользователями и с основным ядром соответственно, в main реализованы модели в которых храниться пользователь. из-за чего я не могу импортировать основные сущности которые относятся к приложению main в users и наоборот, суть ошибки я понимаю но, что делать? Единственное её решение это идти наперерез логике и реализовывать функции там, где им не место, например, я хочу показать сколько пользователь получил лайков на свои посты, и этот метод я реализую в модели Card(мое название для модели постов) хотя по логике должен был в моделе User все это просто по тому что я не могу импортировать нужные мне модели в приложение Users. Пока что все функции я реализовал где это максимально приближенно к логике (не считая модель User) подскажите можно ли как то обойти это ошибку и может это не ошибка вовсе -
Can't use django Form.clean() method

How do I order a many to many relationship based on a field in the intermediary table?
I am writing a django application that tracks ranked statistics for a player in a video game. When I define the "through" field of a many to many relationship, I expect the resulting query to be ordered using the "ordering" meta field of the intermediary object.

Object has no attribute issue
I've followed a tutorial on how to create a CRM via Python, Django and came across an issue in the end result. When I attempt to convert a lead into a client, I am faced with 'Lead' object has no attribute 'comment'. This is present if the lead has comments under it and if it does not. But once I get back to the lead list, I notice that the lead has been converted and duplicate 4 times. Has anyone else come across this issue? And how would I go about fixing it?

CSS Background Image Not Being Applied To Django Project Correctly

Best practice for marking CharFields for translation in django models?
I have a few models for which a specific CharField has to be systematically translated. It appears that those are never picked-up by compilemessages, but are translated ok when the translation is manually introduced into the .po file. Of course it creates an issue each time I update the .po files... which led me several time to loose those specific translation without realizing I therefore wanted to mark those specific CharField for translation once and for all. I was first expecting a declaration in the CharField definition such as: label = models.CharField(max_length=20, default='empty', unique=True, mark_for_translation=True) but looking for it on the documentation, then directly in the Django code ... such a functionality is not currently implemented Then I tried within my code to mark it with gettext_noop, but apparently, in the following code, the corresponding messages are not picked-up during the compilemessages instruction. def difficulty_label_from_index(): difficulties = Difficulty.objects.all().values("label", "index") # Translators: PuzzleDifficulty label return {diff['index']: gettext_noop(diff['label']) for diff in difficulties} Does anyone has a clue why it is not working? or what could be best practices when we need to mark content of a CharField for translation? -

Schema validation error - failed validating 'minItems'
I have a Django (& DRF) application using drf_spectacular. When running manage.py spectacular --validate I got following warning: Warning: encountered multiple names for the same choice set (ProgramTypeEnum). This may be unwanted even though the generated schema is technically correct. Add an entry to ENUM_NAME_OVERRIDES to fix the naming. In order to fix it, I added the problematic (at least that I assume) enum to ENUM_NAME_OVERRIDES: # some/module/enums.py from django.db import models class ProgramTypes(models.TextChoices): A = 'a', 'AAA' B = 'b', 'BBB' # settings.py (...) SPECTACULAR_SETTINGS = { # ... "ENUM_NAME_OVERRIDES": { "ProgramTypes": "some.module.enums.ProgramTypes", }, } Which now results in a schema validation error: E drf_spectacular.management.commands.spectacular.SchemaValidationError: [] is too short E E Failed validating 'minItems' in schema[0]['properties']['enum']: E {'items': {}, 'minItems': 1, 'type': 'array', 'uniqueItems': False} E E On instance['enum']: E [] I'm out of ideas on where to go next. This is problematic as I want to keep a test ensuring there are no schema validation warnings (or errors). -
