Inheritance in Django: Make parent class fall back to child method
Tl;Dr: Circumvent that parents can not call child methods in python (I guess) Consider the following (simplified) django models were MaterialInstance and BookInstance both inherit Item. class Item(models.Model): """Represents an item that is physically in the library""" label = models.CharField(max_length=20, unique=True) @property def description(self) -> str: raise NotImplementedError class BookInstance(Item): """Represents a copy of a book that is physically in the library""" @property def description(self) -> str: return str(self.book) book = models.ForeignKey('Book', on_delete=models.RESTRICT) class MaterialInstance(Item): """Represents a instance of a material that is physically in the library""" @property def description(self) -> str: return str(self.material) material = models.ForeignKey('Material', on_delete=models.RESTRICT, null=True) I want to show all items (books AND material instances) in one table. One row should be a description (either the book title or the material name). It would be nice to use the following template (but this raises a NotImplementedError as the parent class does not try to call child methods. Any suggestions for a clever design that circumvents this problem? <table> <tr> <th>Label</th> <th>Description</th> </tr> {% for item in item_list %} <tr>{{ item.label }}</td> <td>{{ item.description }}</td> </tr> {% endfor %} </table> The final thing should look something like this |Label|Description| |---|---| |B1 | A Boring Book Title| |B2 … -
How can I filter on multiple NOT conditions in Django's ORM?
In Django 3.2, I have the following models: class Person(models.Model): name = models.CharField(max_length=100) class Employment(models.Model): owner = models.ForeignKey('Person', on_delete=models.CASCADE) title = models.CharField(max_length=100) full_time = models.BooleanField(default=True) class Car(models.Model): owner = models.ForeignKey('Person', on_delete=models.CASCADE) color = models.CharField(max_length=100) The Goal: Give me all people that drive a red car (unless they're a full-time firefighter) Here is what I thought would work: Person.objects.filter( ~Q(employment__title='firefighter', employment__full_time=True), car__color='red' ) However, this generates the following SQL: SELECT * FROM "person" INNER JOIN "car" ON ("person"."id" = "car"."owner_id") WHERE "car"."color" = red AND ( NOT ( EXISTS( SELECT (1) AS "a" FROM "employment" U1 WHERE U1."full_time" AND U1."owner_id" = "person"."id" ) AND EXISTS( SELECT (1) AS "a" FROM "employment" U1 WHERE U1."title" = firefighter AND U1."owner_id" = "person"."id" ) ) This in effect returns all people that drive a red car (unless they are a firefighter OR have full-time employment). Like all other filter keys, I would have expected the two conditions on the foreign relation to be ANDED. Why the unexpected behavior? What's the right way to write this so the sql looks like this:? SELECT * FROM "person" INNER JOIN "car" ON ("person"."id" = "car"."owner_id") WHERE "car"."color" = red AND ( NOT ( EXISTS( SELECT (1) AS … -
Django Annotation with boolean field ExpressionWrapper
I'm trying to create a high score statistic table/list for a quiz, where the table/list is supposed to be showing the percentage of (or total) correct guesses on a person which was to be guessed on. To elaborate further, these are the models which are used. The Quiz model: class Quiz(models.Model): participants = models.ManyToManyField( User, through="Participant", through_fields=("quiz", "correct_user"), blank=True, related_name="related_quiz", ) fake_users = models.ManyToManyField(User, related_name="quiz_fakes") user_quizzed = models.ForeignKey( User, related_name="user_taking_quiz", on_delete=models.CASCADE, null=True ) time_started = models.DateTimeField(default=timezone.now) time_end = models.DateTimeField(blank=True, null=True) final_score = models.IntegerField(blank=True, default=0) This models does also have some properties; I deem them to be unrelated to the problem at hand. The Participant model: class Participant(models.Model): # QuizAnswer FK -> QUIZ guessed_user = models.ForeignKey( User, on_delete=models.CASCADE, related_name="clicked_in_quiz", null=True ) correct_user = models.ForeignKey( User, on_delete=models.CASCADE, related_name="solution_in_quiz", null=True ) quiz = models.ForeignKey( Quiz, on_delete=models.CASCADE, related_name="participants_in_quiz" ) @property def correct(self): return self.guessed_user == self.correct_user To iterate through what I am trying to do, I'll try to explain how I'm thinking this should work: For a User in User.objects.all(), find all participant objects where the user.id equals correct_user(from participant model) For each participantobject, evaluate if correct_user==guessed_user Sum each participant object where the above comparison is True for the User, represented by a field … -
why doesn't django log the specified application?
I has some project with application named "work". The directory of the app also named work, and inside apps.py its also named "work", and in INSTALLED_APPS also, etc. And I try to log just the application into file. So. I have prescribed the following settings in settings.py: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'file_logger': { 'format': '%(asctime)s %(name)-12s %(levelname)-8s %(message)s' } }, 'handlers': { 'file_logger': { 'level': 'DEBUG', 'class': 'logging.FileHandler', 'filename': './logging.txt', }, }, 'loggers': { 'work.views': { 'handlers': ['file_logger'], 'level': 'DEBUG', 'propagate': True, }, }, } I initialized inside my views.py (views.py of work app) logger like this: logger = logging.Logger(__name__) where __name__ is "work.views" (I checked this one via debugger) and I have some view, which I want to log: def view_timesheet(request, t_id=None): logger.warning('wwwwwwwwwwwwwwwww') # some code return HttpResponse('ok') but when I execute the code of this view, nothing is written to the file. With what "wwwwwwwww" gets logged in the console This confuses me, because it seems to me that I have done everything according to the documentation and everything should work A few more details: If I write "django" instead of "work.views" all django logs will end up in a file. This leads … -
Why am I unable to set my GeoDjango database engine to 'django.contrib.gis.db.backends.postgis' on heroku?
I've had the same problem for several days now, and it seems like no matter what I do, I can't set my database engine to 'django.contrib.gis.db.backends.postgis' on heroku. The problem has me so stuck that it's driven me to finally make my first Stack Overflow post. I can see the engine is 'django.db.backends.postgresql_psycopg2' when I check the database settings in heroku: % heroku run bash ~ $ python manage.py shell >>> from django.conf import settings >>> settings.DATABASES {'default': {'NAME': [name], 'USER': [user], 'PASSWORD': [password], 'HOST': [host], 'PORT': 5432, 'CONN_MAX_AGE': 600, 'OPTIONS': {'sslmode': 'require'}, 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'ATOMIC_REQUESTS': False, 'AUTOCOMMIT': True, 'TIME_ZONE': None, 'TEST': {'CHARSET': None, 'COLLATION': None, 'MIGRATE': True, 'MIRROR': None, 'NAME': None}}} I've come to believe that the problem has to do with me not understanding how heroku uses the django settings.py file to set up the database. For example, I'm wondering if I'm doing things in the wrong order. Originally, I set up the heroku database with the below commands and then afterwards pushed my geodjango project to Heroku. % heroku addons:create heroku-postgresql:hobby-dev % heroku pg:psql app::DATABASE=> create extension postgis; I've also tried deleting the database entirely and then pushing my code to Heroku because I thought maybe heroku … -
Firebase for notification and aws for backend and database
I am trying to implement a notification system in Django. I find the firebase quite easy which is as follow: from fcm_django.models import FCMDevice device = FCMDevice.objects.all() Now in view: device.send_message(title="Title", body="Message", icon=..., data={"test": "test"}) In settings: FCM_DJANGO_SETTINGS = { # default: _('FCM Django') "APP_VERBOSE_NAME": "[string for AppConfig's verbose_name]", # true if you want to have only one active device per registered user at a time # default: False "ONE_DEVICE_PER_USER": True/False, # devices to which notifications cannot be sent, # are deleted upon receiving error response from FCM # default: False "DELETE_INACTIVE_DEVICES": True/False, # Transform create of an existing Device (based on registration id) into # an update. See the section # "Update of device with duplicate registration ID" for more details. "UPDATE_ON_DUPLICATE_REG_ID": True/False, } Now my question is, we are using AWS for the backend and also for the database. In this case can we use the firebase for notification? How do these two services aws and firebase work together? WIll there be any problem?? -

Wrong distance calculation between two Points in django
I have a model that uses PointField to store location: from django.contrib.gis.db import models from django.contrib.gis.geos import Point class Post(models.Model) location = models.PointField() and trying to do the following calculation: initial_location = Post.objects.first().location last_location = Post.objects.last().location total_distance = initial_location.distance(last_location) The values for this locations are: print(initial_location) >>> SRID=4326;POINT (-1.407385628884526 -24.29361291088179) print(last_location) >>> SRID=4326;POINT (65.55023895708794 43.8537639564256) print(total_distance) >>> 95.53736684717059 Ok, at first glance I thought it was working, but this value is totally wrong. Using this site to convert decimal coordinates to degrees coords and this site to calculate the distance based on this coords, I get a result almost 100 times higher than Django is printing. I'm not sure what is wrong since all of these methods and functions are built-in of the Point class. -

Python Django ModeulNotFoundError: No module named 'SomeFolder'
I have a django app. It is quite complicated, I can't post all the code here, so I have a big picture summary. The setup of the folders in the big picture related to what I'm doing is below. Note that "SomeFolder" is a placeholder name for the actual name. Some folder is a folder containing some python scripts with functions inside of them. It wasn't installed in the Django app. I dragged and dropped SomeFolder into the backend folder. This is necessary and had to be done. It's some python stuff unrelated to Django. Dashboard backend SomeFolder A.py B.py C.py views.py Dashboard frontend manage.py Inside of views.py at the top, I do import SomeFolder Then, inside of views.py, I have a function that calls some of the functions within the python scripts A.py, B.py, and C.py. This is why I need to import SomeFolder. For example: def someFunction(): SomeFolder.A_Function_1 SomeFolder.A_Function_2 SomeFolder.B_Function_2 etc. The issue is, when I run python manage.py runserver I get a ModuleNotFoundError: No module named 'SomeFolder' in views.py. The SomeFolder folder is in the same directory as views.py, so I'm not sure why it's not being recognized. I've seen other similar examples on stackoverflow, but didn't … -

drf> What can I do for using annotate from M2M model
I have 4 models like this. user model class User(model.Model): name=models.ChaField() diary model class Diary(): title=charfield author=Foreignkey("user.User") recommend_diary model class RecommendDiary(): section=Foreignkey("recommend.RecommendSection") diary=Foreignkey("diary.Diary") recommend_section model class RecommendSection(): section=charfield diaries=M2M("diary.Diary", through=RecommendSection) when I give to users recommend item, I want to make an annotation that excludes blocked users. The queryset given to me is this queryset=Recommend.objects.filter(start time-end time) So I can take an object of a given queryset and check numerous diaries associated with this object like this. obj=queryset.first() diary_queryset=obj.diaries.all() (I made custom manager for this) After checking that the request user is blocked from the user who wrote this diary, and I can exclude it from the queryset. diary_list=[diary for diary in diary_queryset if diary.id not in block_list] but I got a filtered list not Queryset. and it is not RecommendSection queryset even. can I get a excluded RecommendSection queryset from blocked user by using annotate or something else? I wanna exclude block user list from RecommendSection ex) queryset=RecommandSection.objects.exclude(diary_id__in=block_user) (it doesnt work btw) I wanna use .annotate if able thx for help. -
Django - Encrypt whole instance
I'm currently figuring out what would be the best way to encrypt an instance of a model in Django. Encrypting single fields seems easy, but I would like to encrypt a whole instance. Context I'm currently building a note-taking application which should have the ability to optionally encrypt a note using a given password. The model looks something like this: class Note(models.Model): title = CharField() content = TextField() created_at = DateTimeField() edited_at = DateTimeField() While I could simply only encrypt the title and content, I don't want that to avoid telling any information about a note when it is encrypted. So basically all fields (event created_at and edited_at) should be encrypted. Thoughts I thought about adding a second model EncryptedNote which only holds a field encrypted_data. This field contains the data in a JSON format in an encrypted form. When the application needs to load the instance, it will decrypt the content and create a Note instance based on the JSON data. However, it feels a little bit off to manually save JSON when using a SQL-like database. Question Is there already a good (and secure) way to encrypt an instance or is this idea of manually encrypting and decrypting … -

Django Rest Framework - How to make extra query before serializer.save
I'm new to Django Rest Framework and I'm trying to do this simple thing, but I'm not sure how to do it. So, this is my models.py class Category(models.Model): name = models.CharField(max_length=250) slug = models.SlugField(max_length=250, unique=True) email = models.EmailField(_('email address'), blank=True, null=True) class Meta: ordering = ('name',) def __str__(self): return self.name class Report(models.Model): category = models.ForeignKey(Category, on_delete=models.PROTECT) description = models.TextField() address = models.CharField(max_length=500) reporter_first_name = models.CharField(max_length=250) reporter_last_name = models.CharField(max_length=250) reporter_email = models.CharField(max_length=250) reporter_phone = models.CharField(max_length=250) report_image_1 = models.ImageField(_("Image"), upload_to=upload_to, null=True, blank=True) report_image_2 = models.ImageField(_("Image"), upload_to=upload_to, null=True, blank=True) report_image_3 = models.ImageField(_("Image"), upload_to=upload_to, null=True, blank=True) date = models.DateTimeField(default=timezone.now) class Meta: ordering = ('-date',) def __str__(self): return self.description I have a form in React that submits, among other values, the category ID. What I need to do, before saving the report to the DB, is send a mail to the email address of that category ID. This is my views.py class ManageCategories(viewsets.ModelViewSet): serializer_class = CategorySerializer def get_object(self, queryset=None, **kwargs): item = self.kwargs.get('pk') return get_object_or_404(Category, slug=item) def get_queryset(self): return Category.objects.all() class ManageReports(viewsets.ModelViewSet): serializer_class = ReportSerializer parser_classes = [MultiPartParser, FormParser] def get_permissions(self): if self.action == 'create': self.permission_classes = [permissions.AllowAny] else: self.permission_classes = [permissions.IsAuthenticated] return super(self.__class__, self).get_permissions() def create(self, request, *args, **kwargs): serializer = ReportSerializer(data=request.data) if … -
Supervisor when uploading a project to the server
I am trying to run my site (Django based) on a VPN server and I am having a problem. I am unable to set up a supervisor. When entering the command sudo supervisorctl reread The message appears: no config updates to processes It is quite possible that this is due to the fact that I changed the configuration file. But what to do now, I do not know. I changed the configuration file, but currently there are no errors.
