Populate parent field from url kwarg in a nested serializer in Django REST Framework
I have 2 models, Catalog and Epic: class Catalog(models.Model): created_on = models.DateTimeField(auto_now_add=True) active = models.BooleanField(null=False, default=False) class Epic(models.Model): name = models.CharField(max_length=128, null=False) slug = models.SlugField(null=False) catalog = models.ForeignKey(Catalog, null=False, on_delete=models.CASCADE) I have created CRUD viewset and serializer for Catalog, using DRF. Now I want to create CRUD viewset and serializer for Epic, to be used like /catalogs/<int:catalog_pk>/epics/<int:pk>. I am using DRF-nested-router: router = routers.SimpleRouter() router.register("catalog", CatalogViewSet) catalog_router = routers.NestedSimpleRouter(router, "catalog", lookup="catalog") catalog_router.register("epics", EpicsViewSet, basename="epics") urlpatterns = router.urls + catalog_router.urls And these are my viewset and serializer for Epic: class EpicsViewSet(mixins.CreateModelMixin, viewsets.GenericViewSet): serializer_class = EpicSerializer permission_classes = (IsAuthenticated, CatalogPermissions) def get_queryset(self): return Epic.objects.filter(catalog=self.kwargs["catalog_pk"]) class EpicSerializer(serializers.ModelSerializer): class Meta: model = Epic fields = "__all__" I am trying to run the creation endpoint like this: POST /catalog/1/epics/ with epic data, but I get the error that catalog field is missing in the payload. I want this to be done automatically from URL kwargs. I want it to take the catalog_id from kwargs and set the catalog instance to the newly created Epic instance in the serializer. The starightforward way would be to override the create function in the serializer, but I am hesitant to do that and was wondering if there is a … -
How to check If the translation of a sql query to Django ORM is equivalent?
I have these models: class Messages(models.Model): channel = models.TextField(blank=True, null=True) message = models.TextField(blank=True, null=True) timestamp = models.TextField(blank=True, null=True) publisher = models.IntegerField(blank=True, null=True) type = models.CharField(max_length=5) class Meta: managed = False db_table = 'messages' class ReadMessages(models.Model): user_id = models.IntegerField(blank=True, null=True) message_id = models.ForeignKey(Messages, db_column='message_id', blank=True, null=True, on_delete=models.CASCADE) class Meta: managed = False db_table = 'read_messages' and I also have a legacy system who is using the same database, but this system is doing the following query in pure sql: SELECT messages1.id, messages1.channel FROM (SELECT * FROM messages WHERE channel IN ('U560')) messages1 LEFT JOIN read_messages ON messages1.id = read_messages.message_id WHERE read_messages.id IS NULL; I tried to do the same in Django ORM using the following code: Messages.objects.filter(channel__in=['U560'],readmessages__id__isnull=True).values('id', 'channel') with the few tests i've done they returned the same result, but I still not sure if they are equivalents and if there will be a case where the two queries will return differents results. -
Highlight words in markdown content according to search result using Reactjs
I am building React/Django app that is using markdown content I want to put a search bar at which the user can search in the blog content and the words that are matching the search results are highlighted. I have used react-highlight-words library but I found that It isn't compatible with markdown content so I am trying using react-string-replace library but there is a problem that faced me in the test react-string-replace returns array not string so I tried to use a hook (useState) which is an empty string and map each word in the array and append it to the hook then put the Hook inside ReactMarkdown element. import React from 'react' import ReactMarkdown from 'react-markdown' import reactStringReplace from 'react-string-replace'; export default function Mark(){ const [stringData, setStringData] = React.useState(""); const content = 'Hey my number is 555-555-5555.'; const replacearray= reactStringReplace(content, 's', (match, i) => ( `===${match}===` )); console.log(replacearray) replacearray.map(word =>{ console.log(word) setStringData(stringData + `${word}`) }) console.log(stringData) return( <ReactMarkdown>{stringData}</ReactMarkdown> ) } The result of console.log(replacearray) is: Array(3) [ "Hey my number i", "===s===", " 555-555-5555." ] The result of console.log(word) is: Hey my number i mark.js:116:13 ===s=== mark.js:116:13 555-555-5555 mark.js:116:13 The result of console.log(stringData) is: 555-555-5555. 555-555-5555. 555-555-5555. 555-555-5555. 555-555-5555. … -
building user-based collaborative filtering system in Django
I'm trying to build a simple user based collaborative filtering in Django for an E-commerce using just the purchase history. Here are the steps I use, I know it needs more improvements but I've no idea what's the next move. here's the product model class Product(models.Model): name = models.CharField(max_length=100) description = models.TextField() here's the purcashe model class Purchase(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) product = models.ForeignKey(Product, on_delete=models.CASCADE) purchase_date = models.DateTimeField(auto_now_add=True) Now to get similar users def find_similar_users(user, k=5): all_users = User.objects.exclude(id=user.id) similarities = [(other_user, jaccard_similarity(user, other_user)) for other_user in all_users] similarities.sort(key=lambda x: x[1], reverse=True) return [user_similarity[0] for user_similarity in similarities[:k]] and to calculate similarity between each: def jaccard_similarity(user1, user2): user1_purchases = set(Purchase.objects.filter(user=user1).values_list('product_id', flat=True)) user2_purchases = set(Purchase.objects.filter(user=user2).values_list('product_id', flat=True)) intersection = user1_purchases.intersection(user2_purchases) union = user1_purchases.union(user2_purchases) return len(intersection) / len(union) if len(union) > 0 else 0 now here's my entry function: def recommend_products(user, k=5): similar_users = find_similar_users(user, k) recommended_products = set() for similar_user in similar_users: purchases = Purchase.objects.filter(user=similar_user).exclude(product__in=recommended_products) for purchase in purchases: recommended_products.add(purchase.product) return recommended_products Now, obviously that'd be really slow, I was thinking of using a copy of the data in another no-sql database.

Django and Huey task issue, record in DB doesn't exist when the task is ran
I am testing Huey with Django and found one issue, tasks can't find the record in DB.

This is running an async task but I am getting the error: app.models.Post.DoesNotExist: Post matching query does not exist. This is not correct, there is a post, and this task is running on a post_save signal.

Running Cron in Django on AWS Elastic Beanstalk without .ebextensions
I'm trying to run a function to count daily active users within a Django application using cron. All guides I can find seem to be many years old and they all reference using a .config file located within .ebextentions folder. My app has been running fine for a while but I haven't actually got a .ebextensions folder so wondering if there's a bad config or if I'm just doing something obvious wrong. Problem: Trying to run cron jobs within Django application running on Elastic Beanstalk in AWS environment.

How do i pack a django module which has other django modules as dependencies?
I am developing a django module which is able to create UI interfaces to query a data repository. The module has an administration interface to configure the access to the data repository. For that it uses several other django modules such as crispy_forms. Following the tutorial at https://docs.djangoproject.com/en/4.1/intro/reusable-apps/, I created a module and uploaded it to test.pypi.org. I can add the module dependencies and upon installing my module, crispy_forms and all other dependencies are installed. This all works fine. But: in order to use my module, the user needs to make a lot of changes to the settings.py and urls.py files. Not only must my module be in INSTALLED_APPS but also my dependencies. Furthermore, to use crispy_forms, I need to specify a CRISPY_TEMPLATE_PACK setting. I always want this setting to be 'bootstrap4' and the user doesn't have to be aware of this setting. So my question is: Is there a way that the inclusion of my module can take care of these dependencies? What I need to have in settings.py: INSTALLED_APPS = [ 'my_module', 'django_tables2', 'crispy_forms', [...] ] CRISPY_TEMPLATE_PACK = 'bootstrap4' DJANGO_TABLES2_TEMPLATE = "django_tables2/bootstrap4.html" What I would like in settings.py: INSTALLED_APPS = [ 'my_module', [...] ] Is there a way … -

Django model, how to auto-increment an object's value
So I have this Django model.py: class Product(models.Model): name = models.CharField(max_length=128) views = models.IntegerField(default=0, blank=True) I would like the views attribute, to have an auto randomly generated number. So something like this: class Product(models.Model): name = models.CharField(max_length=128) views = models.IntegerField(default=0, blank=True) def auto_views(self): return randint(0,200) and the views attribute will automatically take the value of the auto_views() function when creating a new product. In the same way as an auto-slug would work. -

Django and Nginx with Docker
I am trying to use Nginx with Django and Docker in my project. On my computer, I can run the app with docker-compose but I cannot figure out how to use docker-compose to deploy to the docker hub with GitHub actions. What I have done instead is use WhiteNoise and not Nginx to be able to manage my static and media files. Here is the repo of what is working and any guidance will be greatly appreciated. If using WhiteNoise is also acceptable and has no drawbacks that would be good to hear as I have seen different views in that regard. -
How to make every subsequent page retain the slug in the URL and append URI
I'm making a Django website and I have 2 apps within it. Once the user is logged in and navigates to the dashboard area of the site I would like them to select a tenant to manage and for every subsequent menu button clicked to be in the context of that tenant. For example a user logs in with access to a 'tenant1'. I would like to the urls to all follow the format http://mywebsite/tenant1/. So far I've managed to create a tenant selector page successfully and navigate to the dashboard from there by adding the slug. The issue is every subsequent page no longer contains the slug, and I'm not sure how to access the slug from the previous page to be able to access it in the href. Even so I can see a solution that relies on the previous pages slug to be troublesome as some navigation options don't require the slug, just the user info. Here is my URLs.py urlpatterns = [ path('', tenant_selector.as_view(), name='tenant_selector'), path('<slug:slug>/dashboard', Dashboard.as_view(), name='Dashboard'), path('<slug:slug>/config/', config_view.as_view()), path('<slug:slug>/run_func/', loading_view.as_view()), path('profile/', user_update_view.as_view(), name='Profile'), path('success', Success.as_view()), ] Below is the Views.py class Dashboard(TemplateView): template_name = "dashboard.html" def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['total'] = staff_sync_model.objects.count() … -
How to run django runserver in a background thread?
I need to run django runserver in the background to enable tests with selenium and pytest. A similar functionality is provided by pytest-django's live_server. But using live_server flushes the database after each test which implies recreation of tables and migrations on each test which is redundant and unacceptably slow. My main objective is to create a database and test user, login with selenium once and run all tests which is clearly impossible using pytest-django's live_server. As per the docs: you need to repopulate your database every time a test starts, because the database is cleared between tests and there is no way around it. So the solution is to run a django server in the background and use it instead. Here's a couple of approaches: Using a thread: import os from pathlib import Path from threading import Thread from django.core.management import call_command from django.core.wsgi import get_wsgi_application def start_server(src): os.chdir(src) os.environ.setdefault('DJANGO_SETTINGS_MODULE', f'{Path(src).name}.settings') os.environ['DB_NAME'] = 'test_db.sqlite3' get_wsgi_application() call_command('migrate') call_command('runserver') def run_server(src): process = Thread(target=start_server, args=[src], daemon=True) process.start() if __name__ == '__main__': run_server('/path/to/myproject-root') which results in an error: Traceback (most recent call last): File "/usr/local/Cellar/python@3.11/3.11.2_1/Frameworks/Python.framework/Versions/3.11/lib/python3.11/threading.py", line 975, in run self._target(*self._args, **self._kwargs) File "/Users/user/Library/Application Support/JetBrains/PyCharm2022.3/scratches/scratch_3.py", line 15, in start_server call_command('runserver') File "/usr/local/lib/python3.11/site-packages/django/core/management/__init__.py", line 198, … -
accessing django admin using angular frontend
I want to access django admin using angular frontend. I am not sure if its even possible. I am using angular as my frontend (angular ver:8.0) and django as my backend. I have also added admin in my urls.py file as given below from django.urls import path, re_path from django.contrib import admin from django.views.debug import default_urlconf router = routers.DefaultRouter() urlpatterns = [ url(r'^', include(router.urls)), re_path(r'^superadmin/', admin.site.urls), re_path(r'^$', default_urlconf),] but when open http://localhost:4203/admin/ it doesnt open django admin panel. (http://localhost:4203/ is my local angular server) How can I achieve this? Is it even possible to use django admin panel with angular frontend? Please help. -
How can I get my AJAX button press request to work in my Django environment?
So basically I want to use a javascript string variable in a python function, and then return it back to a javascript variable. To start, I have a html element where a string is placed in it. <h2 id="output"></h2> My plan is to pull that value from the HTML (shown in the AJAX statement below): var word = $("#output").val(); and use AJAX to send it to the backend for a python script that checks whether or not the word is a real English word (returning true/false). With the AJAX code I have, I keep getting returned an undefined variable. Here is the AJAX code: $(document).ready(function() { $('#submit_word').click(function() { var word = $("#output").val(); $.ajax({ url: '{% url 'wordgame' %}', //not sure type: 'POST', dataType: 'json', data: {word:word, csrfmiddlewaretoken: "{{ csrf_token }}",}, success: function(response) { var word_result = JSON.parse(response.result); console.log(response.result); $("#check-word").text(word_result); }, error: function(response) { console.log(response.result); } }); }); }); As well as my views function: def fetch_word(request): word = request.POST.get('word') result = check_if_word_in_dictionary(word) return JsonResponse({'result': result}) Whenever I click the button, it executes the 'error' part of my ajax statement: error: function(response) { console.log(response.result); } Which prints 'undefined' in the console. -
get_absolute_url is NOT working on the combined queryset, How can l do it?
I want to use get_absolute_url but it shows nothing on the combined queryset It returns an error that: Page not found Below are my codes #Action/models.py class Action(models.Model): ...... def get_absolute_url(self): return reverse('act',args=[self.slug]) #adventure/models.py class Adventure(models.Model): ...... def get_absolute_url(self): return reverse('adves',args=[self.slug]) #racing/models.py class Racing(models.Model): ...... def get_absolute_url(self): return reverse('act',args=[self.slug]) #puzzle/models.py class Puzzle(models.Model): ...... def get_absolute_url(self): return reverse('puz',args=[self.slug]) Then view of my combined queryset #Others/views.py from itertools import chain def games(request): ... ..... act_games=Action.objects.all() adv_games=Adventure.objects.all() puz_games=Puzzle.objects.all() rac_games=Racing.objects.all() games= list(chain(act_games,adv_games,puz_games,rac_games)) context={ 'games':games, } return render(request,'combined.html', context) #combined.html ....... {% for game in games %} <div class="col"> <a href="{{ game.get_absolute_url }}"> {{ game.game_name }} </a> {% endfor %} ..... My Expections When I refleshed the page l found no error. But when I tried clicking on the link, It returned an error that Page not found Now l would like to know how make it pass successfully and take me to the slug link added when creating the object. E.g When clicking on the action game on the combined page when it was created in the Action models it must redirect me to the slug link page but just returns me 404 Page not found
