How can I join multiple models in Django into a virtual table?
If I have 3 models, like: class Cow(models.Model): name = number_of_eyes = number_of_feet = color = class Pig(models.Model): name = number_of_eyes = number_of_feet = intelligence = class Horse(models.Model): name = number_of_eyes = number_of_hooves = weight_capacity = speed = And I'm interested in making a single Livestock table in my template that has instances of all 3, but I'm only interested in these columns that all 3 models have: name number_of_eyes number_of_feet (number_of_hooves if Horse) And we can ignore all other columns. How can I join them into a single queryset? The end goal is to get a single virtual table (queryset) that I can do a few other operations on (order_by, slice), and then return the data in just those columns. Is this possible in the Django ORM? -

Django Rest Framework: saving data into database from a particular input structure
This is my first time with Django Rest Framework. I have two particular models for storing data into the database whose are: class RuleTree(models.Model): ruleId = models.IntegerField(primary_key=True) parentId = models.IntegerField() keyText = models.CharField(max_length=200) class RuletreeExtended(models.Model): rule = models.OneToOneField(RuleTree,on_delete=models.CASCADE,primary_key=True) createdOnUtc = models.TextField(blank=True) bodyRegion = models.CharField(blank=True,max_length=100) isActive = models.BooleanField(blank=True) I need to design an API with the following structured inputs and save them to the pre-defined database model (there are several more fields in this input structure that need to access from views.py and will be useful later). { "Success": true, "Status": "insert", "Data": { "RuleJson": "{\"condition\":\"AND\",\"rules\":[{\"condition\":\"OR\",\"rules\":[{\"id\":\"1206\",\"field\":\"ansid_1206\",\"type\":\"integer\",\"input\":\"checkbox\",\"operator\":\"in\",\"value\":[2620,2621,2622]},{\"id\":\"1383\",\"field\":\"ansid_1383\",\"type\":\"integer\",\"input\":\"checkbox\",\"operator\":\"in\",\"value\":[3058,3059,3060,3061,3062,3063,3064,3065,3066,3067]}]}],\"valid\":true}", "ICD10Codes": "3916", "CreatedOnUtc": "2021-11-01T10:33:13.7145563", "UpdatedOnUtc": "2021-11-09T13:04:01.3089361", "BodyRegion": [ 0, 1, 5 ], "IsDefaultBodyRegionRule": false, "DefaultBodyRegionList": [ 0, 4 ], "IsActive": false, "IsDeleted": false, "Id": 5504, "ParentId": 276, "KeyText": "PFRProv1", "Title": "Plantar Fasciitis Right" } } Please advise me how to access this input data from views.py so that I can store them in my database; And how do I design a suitable serializer for this. -
Django display several foreign key values in template
I have tried dozens of solutions on her to solve this but nothing seems to be working as expected. I'm trying to show a list of Facilites which are connected with several Foreign Keys to additonal models. (FacilityAddress, FacilityInspectionInfo and FacilityComplaints). I can show the facility names but i cannot show the data of the models within the foreign key models like FacilityAddress for example: Model class Facility(models.Model): UUID = models.CharField(max_length=150, null=True, blank=True) Name = models.CharField(max_length=50, null=True, blank=True) admin_uid = models.OneToOneField(User, null=True, blank=True, on_delete=models.SET_NULL) IssuedNumber = models.CharField(max_length=20, null=True, blank=True) mainimage = models.ImageField(null=True, blank=True) Capacity = models.IntegerField(null=True, blank=True) Licensee = models.CharField(max_length=50, null=True, blank=True) Email = models.EmailField(max_length=30, null=True, blank=True) AdministratorName = models.CharField(max_length=30, null=True, blank=True) Status = models.CharField(max_length=10, null=True, blank=True) TelephoneNumber = models.CharField(max_length=20, null=True, blank=True) ClosedTimestamp = models.IntegerField(null=True, blank=True) MostRecentLicenseTimestamp = models.IntegerField(null=True, blank=True) class Meta: verbose_name_plural = "facilities" def __str__(self): return self.Name class FacilityAddress(models.Model): PrimaryAddress = models.CharField(max_length=50, null=True, blank=True) SecondaryAddress = models.CharField(max_length=50, null=True, blank=True) City = models.CharField(max_length=50, null=True, blank=True) RegionOrState = models.CharField(max_length=30, null=True, blank=True) PostalCode = models.CharField(max_length=20, null=True, blank=True) Geolocation = models.CharField(max_length=20, null=True, blank=True) AddressInfo = models.ForeignKey(Facility, null=True, blank=True, on_delete=models.CASCADE) class Meta: verbose_name_plural = "facility addresses" def __str__(self): return f"{self.PrimaryAddress} {self.City}" class FacilityInspectionInfo(models.Model): ComplaintRelatedVisits = models.IntegerField(null=True, blank=True) InspectionRelatedVisits = models.IntegerField(null=True, blank=True) NumberOfVisits = … -
CommandError: 'D:\Python\Project\resume_1' already exists
I am creating a django project. I can successfully create virtual environment and pip install django, but when I try to create project using django-admin startproject resume_1 There is an error that showed CommandError: 'D:\Python\Project\resume_1' already exists I tried uninstalling django twice but it only allowed me to uninstall once, so it is likely not about duplicate django, I also checked the lib\site-packages, there are no duplicated folders or folders either. However, I do have two versions of python right now, one installed along with anaconda, one is separated from anaconda and directly downloaded from python.org. Right now, I am just using the separate python, I even checked the python version, and the pip version, so it should be fine. Still, I could be wrong since I am not that experienced. What should I do? -

Converting SQL to something that Django can use
I am working on converting some relatively complex SQL into something that Django can play with. I am trying not to just use the raw SQL, since I think playing with the standard Django toolkit will help me learn more about Django. I have already managed to break up parts of the sql into chunks, and am tackling them piecemeal to make things a little easier. Here is the SQL in question: SELECT i.year, i.brand, i.desc, i.colour, i.size, i.mpn, i.url, COALESCE(DATE_FORMAT(i_eta.eta, '%M %Y'),'Unknown') as eta FROM i JOIN i_eta ON i_eta.mpn = i.mpn WHERE category LIKE 'kids' ORDER BY i.brand, i.desc, i.colour, FIELD(size, 'xxl','xl','l','ml','m','s','xs','xxs') DESC, size+0, size Here is what I have (trying to convert line by line): (grabbed automatically when performing filters) (have to figure out django doc on coalesce for syntax) db alias haven't been able to find yet - it is crucial since there is a db view that requires it already included in the original q .select_related? .filter(category="kids") .objects.order_by('brand','desc','colour') - don't know how to deal with SQL FIELDS Any advice would be appreciated! -
Gunicorn Not Finding Dotenv
I'm in the process of setting up a Digital Ocean Ubuntu VPS with Django following the instructions they supplied. I was able to run: python3 manage.py runserver 0.0.0.0:8000 The application came up and worked. It's a copy from my development machine. The next step is to test Gunicorn. The command given is: gunicorn --bind 0.0.0.0:8000 fosteryouth.wsgi The process exits with the last of the error messages being: File "/var/www/fosteryouth/fosteryouth/settings.py", line 15, in <module> from dotenv import load_dotenv ModuleNotFoundError: No module named 'dotenv' [2021-12-19 00:43:51 +0000] [59490] [INFO] Worker exiting (pid: 59490) [2021-12-19 00:43:51 +0000] [59488] [INFO] Shutting down: Master [2021-12-19 00:43:51 +0000] [59488] [INFO] Reason: Worker failed to boot. The first non-comment lines from my setting file are: from pathlib import Path import os from dotenv import load_dotenv load_dotenv(override=True) Line 15 is "from dotenv import load_dotenv" There was no problem finding it when using runserver above. I'm using virtualenv and it is activated. I've set up number other Django servers on Digital Ocean in the past. At the time, the instructions didn't include this step. You went directly the setting up socket and services files for gunicorn. Any idea what the problem is? Ubuntu 20.04, Django 4.0, Python 3.8 -
Run tests on Heroku Docker container with GitHub Actions
I am successfully deploying to Heroku a dockerized Django app via GitHub Actions. My GitHub Actions workflow: name: Deploy to heroku. on: push: branches: [poet] jobs: build: runs-on: ubuntu-latest steps: # Check-out your repository. - name: Checkout uses: actions/checkout@v2 # Build and deploy - name: Build, push, and release Docker to Heroku. uses: gonuit/heroku-docker-deploy@v1.3.3 with: email: <email> heroku_api_key: ${{ secrets.HEROKU_API_KEY }} heroku_app_name: <app> dockerfile_directory: ./image/app/ dockerfile_name: Dockerfile docker_options: "--no-cache --target prod" process_type: web - name: Test run: python manage.py test # this doesn't work First of all, I'd like to confirm that the test step should be something like what I show above (name: Test). In other words, should testing be another step in the build job? Or should it be it's own job? Running that command as a step within the same job produces the error python: can't open file 'manage.py'. Alternatively, if I were to make it its own job, I suppose I should try with heroku ps:exec. However, to interact with a Docker container in Heroku apparently requires a lot of modifications and I'm not convinced that's the way to go yet. For what it's worth, if I try to run the console in Heroku and in … -
How to unhash a password in Django if you know the Secret Key
I have a simple Django website setup. For a science fair project, i am showing vulnerabilities in Django. I know the secret key of the website, and I have a hashed password.

Summing columns in Django with related fields
I'm trying to do some aggregation on some of my Django columns, but I'm getting an error I can't figure out. Here are my models (the relevant stuff anyways): class Fillup(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL,on_delete=models.CASCADE) date = models.DateField(default=date.today) trip_distance = models.FloatField(validators=[MinValueValidator(0.0)]) car = models.ForeignKey('Car',on_delete=models.CASCADE, related_name='fillups') class Car(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL,on_delete=models.CASCADE) name = models.CharField(max_length=25) So each Fillup object is essentially a tank of gas in a car, and what I want to do is get the total of the trip_distance column for each car. I've tried several things from various other StackOverFlow pages, but nothing seems to work. My first attempt was this adding this field to the Car Model: @property def distance_driven(self): return self.fillups.aggregate(sum('trip__distance')) But I just get the following error: TypeError: unsupported operand type(s) for +: 'int' and 'str' I also tried adding this to my serializer, but got the same error: distance_driven = serializers.SerializerMethodField() def get_distance_driven(self, ob): return ob.fillups.all().aggregate(sum('trip_distance'))['trip__distance'] Is there something I'm missing here? I don't understand why I'm getting that error when trying to sum a FloatField column. Any help would be greatly appreciated! -

Archive records and re-inserting new records in Django?
I've got a Stock table and a StockArchive table. My Stock table consists of roughly that 10000 stocks that I update daily. The reason I have a StockArchive table is because I still wanna some historic data and not just update existing records. My question is, is this a proper way of doing it? First, my models: class Stock(models.Model): objects = BulkUpdateOrCreateQuerySet.as_manager() stock = models.CharField(max_length=200) ticker = models.CharField(max_length=200) exchange = models.ForeignKey(Exchange, on_delete=models.DO_NOTHING) eod_price = models.DecimalField(max_digits=12, decimal_places=4) currency = models.CharField(max_length=20, blank=True, null=True) last_modified = models.DateTimeField(blank=True, null=True) class Meta: db_table = "stock" class StockArchive(models.Model): objects = BulkUpdateOrCreateQuerySet.as_manager() stock = models.ForeignKey(Stock, on_delete=models.DO_NOTHING) eod_price = models.DecimalField(max_digits=12, decimal_places=4) archive_date = models.DateField() class Meta: db_table = "stock_archive" I proceed on doing the following: @transaction.atomic def my_func(): archive_stocks = [] batch_size = 100 old_stocks = Stock.objects.all() for stock in old_stocks: archive_stocks.append( StockArchive( stock=stock.stock, eod_price = stock.eod_price, archive_date = date.today(), ) ) # insert into stock archive table StockArchive.objects.bulk_create(archive_stocks, batch_size) # delete stock table Stock.objects.all().delete() # proceed to bulk_insert new stocks I also wrapped the function with a @transaction.atomic to make sure that everything is committed and not just one of the transactions. Is my thought process correct, or should I do something differently? Perhaps more efficient? -

Django smart selects chain 2 models with country list that is not its own model
I have 3 models CompanyRole, Office and extended user model - and have successfully implemented django smart selects package and have created a ChainedForeignKey select from Office to CompanyRole. CompanyRole model having records employee and freelance and Office model having the office name and companyrole field for employee only - this works as expected as in dropdown for companyrole user selects employee then in dropdown for offcies will be populated but if freelance selected from company role dropdown then nothing will be populated in office dropdown. However, I also have a field in user model called location and country field in office model which populates a country list from django_countries package so did not have to create a model for countries.

Django sum of a particular field for some distinct column
I have a table OrderTransaction which has foreign key for table Order. I want to calculate the outstanding amount i.e. the amount for which transaction has not yet occurred. To calculate that I first need to calculate the total amount (Order table has field total amount) so that I can subtract the amount of transaction that has taken place from it. I am grouping by the the query by recorded_by field because I need to know what salesman has collected how much amount. Following is my query. order_transaction_qs .exclude(recorded_by=None) .order_by("recorded_by") .values("recorded_by") .annotate( cash_in_hand=Coalesce( Sum("amount", filter=Q(payment_method=PaymentMethod.CASH_ON_DELIVERY)), Value(0) ), cheque=Coalesce( Sum("amount", filter=Q(payment_method=PaymentMethod.CHEQUE)), Value(0) ), others=Coalesce( Sum( "amount", filter=~Q( payment_method__in=[ PaymentMethod.CHEQUE, PaymentMethod.CASH_ON_DELIVERY, ] ), ), Value(0), ), order_amount=Sum( "order__total_amount" ), # NOTE: Multiple transactions on same orders will give extra amount. outstanding=ExpressionWrapper( F("order_amount") - (F("cash_in_hand") + F("cheque") + F("others")), output_field=FloatField(), ), ) The problem with above query is that if there are multiple transaction for same order, it is adding the total_amount multiple times.

How do I link a Django foreign key selected in a form with an inline form?
Introduction Hello!

I have the following types of models: Truck - a single truck Service - a single instance of a repair/maintenance service for a single truck Photo - a single picture from the photologue app PhotoExtended - an add-on model one-to-one with Photo where it can be linked to a truck and/or a service.
