How can I get the records (of a specific model) of both request.user and a specific user?
I am not very professional in django rest... I wrote a blog with django rest framework and There is no problem when I want to get all the records related to the Article model or get a specific article, for example But what I want to do is to send an user id(or an user name) to the view when I click on the user's name. and as a result display all the records of the Article model related to the request.user and all the records of the Article model related to the user whose name was clicked. In fact, I want to click on the name of each user, in addition to getting the Articles of that user, the Articles related to the request.user will also be taken This is what I have done so far... #models.py class Article(models.Model): title = models.CharField(max_length=255) slug = models.SlugField author = models.ForeignKey(User , on_delete = models.CASCADE) content = models.TextField(null = True) publish = models.DateTimeField(default = timezone.now) created = models.DateTimeField(auto_now_add = True) updated = models.DateTimeField(auto_now = True) status = models.BooleanField(default = False) def __str__(self): return self.title class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) name = models.CharField(max_length=100) pic = models.ImageField(upload_to="img", blank=True, null=True) def __str__(self): return self.user.username … -

Implement adding an image from gallery to favourites, which is displayed on a separate page// DJANGO/JS
Essentially I am creating a web gallery with Django/JS for a project, however the project needs to feature CRUD functionality. Currently I have a functioning modal when an image in the gallary is clicked, along with an "Add to Favourites" button when the user is logged in. I am struggling to come up with a way to append these images dynamically to the favourites HTML page. I am unsure whether this is easier done with JS or Django. Here is my current JS code: $(function() { $('.myImg').each(function() { $(this).click(function() { $('#myModal').css('display', 'block') $('#imgModal').attr('src', this.src) $('.navbar').css('display', 'none') }) /* Favourite image functionality */ var favouriteImages = [] imgSrc = $(this).attr('src', this.src); $('#favourites-btn').click(function () { favouriteImages.push(imgSrc) }) }) $('.close').each(function() { $(this).click(function() { $('#myModal').css('display', 'none') $('.navbar').css('display', 'flex') }) }) }) favouriteImages.forEach(function() { $('#favourites-gal').append(<img class='myImg'/>) }) At the bottom, with the favouriteImages.forEach function, I dont know how to include the src of the specific image that is being appended after clicking the Add to Favorites button. For reference: In the actual gallary of images the code structure of the HTML is: <div class="gal"> <img class="myImg" src="{% static 'img/artsy-gallery/artsy1.webp' %}" alt=""> <img class="myImg" src="{% static 'img/artsy-gallery/artsy2.webp' %}" alt=""> <img class="myImg" src="{% static 'img/artsy-gallery/artsy3.webp' %}" alt=""> … -
MYSQL Database Copy Using Python/Django

Serve TailwindCSS with django_plotly_dash
I have a Dash app in Django being served via django-plotly-dash and I'm using Tailwind for the styling across the site. Tailwind seems to be working everywhere except for the Dash app, where it is kind of working, but seems to be overwritten by the Bootstrap at some points. I can see the Tailwind styling without any issues if I run the Dash app on its own, but not when embedded in Django. Here's the view inside Django (and the code for this basic example): And here it is (with garish colors to see the difference) while running Dash and Tailwind without Django: Some of the Tailwind styling is being applied, such as the container mx-auto bit of the Dash layout, but others (e.g. coloring) are being dropped. Here's the code for the Dash app, which is split into layout.py, callbacks.py, and dashboard.py: layout.py: from dash import dcc, html layout = html.Div( className="bg-green-100 container mx-auto my-auto px-15 py-5", children=[ html.Div( className="bg-red-100 py-5", children=[ dcc.Dropdown( id="symbol-input", options=[ {"label": "Apple", "value": "AAPL"}, {"label": "Tesla", "value": "TSLA"}, {"label": "Meta", "value": "META"}, {"label": "Amazon", "value": "AMZN"} ], searchable=True, value="AAPL", ) ]), html.Div( className="max-w-full shadow-2xl rounded-lg border-3", id="price-chart" ) ] ) callbacks.py: from dash import … -
How can I serialize a Many to Many field with added data in Django Rest Framework, without extra keys in the response?
I am using Django 3.2 and Django Rest Framework 3.14. I have Users that should be able to follow other Users, like on a social networking site. When serializing a full User, I would like to get a list of those following Users, as well as additional data, such as the follow datetime. However, I would like the response to stay "flat", like this: { "username":"admin", "followers":[ { "username":"testuser", --additional user fields-- "follow_date":"2023-02-08 01:00:02" }, --additional followers-- ], --additional user fields-- } I can only seem to go "through" my join model using an extra serializer, and end up with this: { "username":"admin", "followers":[ { "user":{ "username":"testuser", --additional user fields-- }, "follow_date":"2023-02-08 01:00:02" }, --additional followers-- ], --additional user fields-- } Note how there is an additional user key "user":{ "username":"testuser", --additional user fields-- }, I don't want that there! My model looks something like this: class Follower(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.RESTRICT, related_name="followers") follower = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.RESTRICT, related_name="following") follow_date = models.DateTimeField(auto_now_add=True) My serializers look like this (extra fields trimmed for brevity): class UserSnippetSerializer(serializers.ModelSerializer): class Meta: model = User fields = ['username'] class FollowerSerializer(serializers.ModelSerializer): user = UserSnippetSerializer(source='follower') class Meta: model = Follower fields = ['user', 'follow_date'] class FullUserSerializer(serializers.ModelSerializer): followers = FollowerSerializer(source='user.followers', … -
Django Many to Many Field Set in Model Save Method
I am trying to override the save method in a model with logic to update a couple of many to many fields. Using print statements I can see values updating as expected but the values are not persisted after save.

Getting Bad Request from POST to DailyWc Model with a ForeignKey to Projects
I'm making a writing app using Django backend and Vue 2 frontend. I have two models— DailyWc and Project. Every day, when the user goes to the site, a new day is created for them to store text (DailyWc handles this). I wanted it to be possible for the user to also assign the text to a Project, with the default being "Unassigned." So, Project is associated with multiple dailywcs. There's a button on my site that the user can press to save their progress for the day. This is where my trouble comes in— I can't make post or update calls because I'm getting Bad Request. My understanding is that I should be able to just pass in the associated project id to make this work, but I think the DailyWc model as it is now is expecting a whole Project object with related fields. My models: # Create your models here. class Project(models.Model): name = models.CharField(max_length=255, default="Unassigned") start_date = models.DateField("today's date", default=datetime.date.today) end_date = models.DateField("end date", default=datetime.date.today) word_count_goal = models.PositiveIntegerField(default=0) def __str__(self) -> str: return f'The Project {self.name} started on {self.start_date} and will end on {self.end_date} with a goal of {self.word_count_goal} and an id of {self.id}.' class DailyWc(models.Model): … -
The current path didn’t match any of these. Django Project/ Learning_Log
I am studying working with Django from a book Python Crash Course by Eric Matthes. I follow all recommendations and write code one-to-one like in a book, but i have encountered such a problem. I cant go to detailed topic page from a topics link, but manually i can.

How can I use Visual Studio Code to debug Django with an IP address defined by myself? (By that I would test my app on an android phone)

But when I use VScode in debug mode I don't know where I can define the server other than 127.0.0.0.1:8000. Having 127.0.0.0.1:8000 I can access the page just by my pc (win 10).

how can I use `return HttpResponseRedirect(reverse("some-path", args=[slug]))` with user_agent?
I'm looking for a way to use (in the views.py) return HttpResponseRedirect(reverse("some-path", args=[slug])) where I can define to which template a user will be redirected according to the device. The problem is related to the Class-based view with the get and post methods. In my post function I have this unsolved problem in my return statement. I couldn't find an answer anywhere: what's the best approach for this situation? The problem is that redirection uses just url.py and I don't know where and how can I write the if statement about the devices, like in normal view function: if user_agent.is_pc: return render( request, 'dev/registration-success_pc_tablet.html', { 'my_email': my_email }) elif user_agent.is_mobile: return render( request, 'dev/registration-success_mobile.html', { 'my_email': my_email }) elif user_agent.is_tablet: return render( request, 'dev/registration-success_pc_tablet.html', { 'my_email': my_email }) I have set my MIDDLEWARE, INSTALLED_APPS for user_agent. The problem is just with this particular case that I described in my question. -

This is my code: # models.py from django.db import models from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin, BaseUserManager from django.core.validators import RegexValidator class MyAccountManager(BaseUserManager): def create_superuser(self,username, email, phone_number,password, **other_fields): other_fields.setdefault('is_staff', True) other_fields.setdefault('is_superuser', True) other_fields.setdefault('is_active', True) if other_fields.get('is_staff') is not True: raise ValueError('Superuser must be assigned to is_staff=True') if other_fields.get('is_superuser') is not True: raise ValueError('Superuser must be assigned to is_superuser=True') user = self.create_user(username,email, phone_number, password, **other_fields) user.set_password(password) user.save() return user def create_user(self, username, email, phone_number,password,**other_fields): if not email: raise ValueError('') email = self.normalize_email(email) if password is not None: user = self.model(username=username,email=email, phone_number=phone_number,password=password, **other_fields) user.save() else: user = self.model(username=username,email=email, phone_number=phone_number, password=password,**other_fields) user.set_unusable_password() user.save() return user class Account(AbstractBaseUser, PermissionsMixin): email = models.EmailField(unique=True) username = models.CharField(max_length=150,unique=True) phone_number = models.CharField(max_length=17, unique=True) is_staff = models.BooleanField(default=False) is_active = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) objects = MyAccountManager() USERNAME_FIELD = 'phone_number' REQUIRED_FIELDS = ['email', 'username'] # views.py from django.shortcuts import render, redirect, HttpResponse from django.contrib.auth import authenticate, login, get_user_model from .forms import … -
Can't handle with Django Model related objects for Analysis-tracking App
I'm trying to make a web app that allows to add patients and add then track their medical analyses. Example Trying to make models for it... Could you advise me: what is the strategy if my next purpose is to make form that allows to fill in all lines from analysis group. Should I move in this way? (So next will be problems with orm queries) I tried to deal with next solution but maybe u will take a professional look at this? Really appreciate patient/models.py: class PatientGender(models.Model): gender = models.CharField(max_length=16) def __str__(self): return f"{self.gender}" # Create your models here. class Patient(models.Model): hist_number = models.IntegerField(unique=True, verbose_name='Номер истории болезни') last_name = models.CharField(max_length=32, verbose_name='Фамилия') first_name = models.CharField(max_length=32, verbose_name='Имя') second_name = models.CharField(max_length=32, verbose_name='Отчество') birth_date = models.DateField(verbose_name='Дата рождения') date_time = models.DateField(auto_now_add=True, verbose_name='Время поступления в ОРиТ') sex = models.ForeignKey(PatientGender, verbose_name='Пол', on_delete=models.CASCADE, default=1) seat = models.PositiveSmallIntegerField(verbose_name='Палата', blank=True, null=True) description = models.TextField(blank=True, verbose_name='Палата') is_Active = models.BooleanField(verbose_name='Находится на лечении', default=True) def __str__(self): return f"{self.hist_number}: {self.last_name} {self.first_name} {self.second_name}" analysis/models.py: class AnalyzesGroup(models.Model): name = models.CharField(max_length=256, verbose_name='Группа исследований') description = models.TextField(blank=True, verbose_name='Примечание') class Meta: verbose_name = 'Группа анализов' verbose_name_plural = 'Группы анализов' def __str__(self): return f"{self.name}" class AnalysisType(models.Model): name = models.CharField(max_length=256, verbose_name='Исследование') measurement = models.CharField(max_length=10, verbose_name='Единицы измерения') ref_min = models.FloatField(verbose_name='Мин. реф. … -
Limit instantiations of class with particular value to one - django
I have two classes in a django app, project and plan The project class has an is_global boolean field, as does the plan class. The plan also has a foreign key to the project class (projects have multiple plans). I am trying to accomplish the following: for both projects and plans, there should only ever be one instance of each where is_global = true. The global plan should belong to the global project. Is it possible to enforce this logic with django models? -
EventConsumer() missing 2 required positional arguments: 'receive' and 'send', while using AsyncWebSocketConsumer
The problem is, that i dont understand why it asks me for 2 positional arguments here, and i didnt see any other problem like this. There were suggestions to update 'channels' library, or to really add that 'send' and 'receive' functions into my Consumers class. But neither of that has any impact on my code. I have tried different variations of routing, setting up asgi, or configuring Docker-compose and nginc.config file. But still nothing helps. The idea is that i just want My WebSocket to be sending me events which are saved to events from POST, or which is about to be saved. Here is my consumers.py: from channels.generic.websocket import AsyncWebsocketConsumer from .models import ( WorkingMode, CarParkItem, Events ) import json class EventConsumer(AsyncWebsocketConsumer): async def connect(self): await self.accept() await self.channel_layer.group_add("events", self.channel_name) print("Connected to events") async def disconnect(self, close_code): await self.channel_layer.group_discard("events", self.channel_name) print("Disconnected from events") async def receive(self, text_data): text_data_json = json.loads(text_data) cam_id = text_data_json['cam_id'] vehicle_plate = text_data_json['vehicle_plate'] is_recognition = text_data_json['is_recognition'] is_confirmation = text_data_json['is_confirmation'] working_mode = WorkingMode.objects.get(pk=cam_id) event_code = None if working_mode.pass_mode == 'closed': event_code = 1009 else: car_park_item = CarParkItem.objects.filter(vehicle_plate=vehicle_plate).first() if car_park_item: event_code = 1008 else: if is_recognition and is_confirmation: event_code = 1007 elif is_recognition and not is_confirmation: event_code = …
