Updated data don't seem in DRF api response
The updated data doesn't seem in api response. When I add or update some data in admin panel it doesn't affect to api response. To fix it i must write docker-compose restart. How can i fix this problem I supposed that this problem comes from caches issue. Therefore i add cache configuration in settings like this: `CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.dummy.DummyCache', } }` But it doesn't fix problem -
how to add Comment form inside a post detailed
Is there any way I can add a comment form inside a post's details? I have a view that shows a model object, and I want to allow users to comment on that view. I have tried to use this method, but using that method, a user should leave a post's details and add their comment somewhere else rather than doing it inside a post's details? I have try to do that using the method below, but it gives me an error every time I clicked on submit button: TypeError at /video-play/so-da-shakuwa/ Field 'id' expected a number but got <Video: videos/DJ_AB_-_Masoyiya_Official_Video_9UfStsn.mp4>. views: def play_video(request, slug): play = get_object_or_404(Video, slug=slug) if request.method == 'POST': comments = request.POST['comments'] new_comment = Comment.objects.create( comments=comments, post_id=play ) new_comment.user = request.user new_comment.save() return redirect('Videos') context = { 'play':play } return render(request, 'video/play_video.html', context) template: <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC" crossorigin="anonymous"> <div class="container"> <div class="row"> <div class="col-md-9"> <form action="" method="post"> {% csrf_token %} <div class="input-group"> <textarea name="comments" id="comment" cols="10" class="form-control" placeholder="write your comment"></textarea> <button class="btn btn-primary" type="submit">submit</button> </div> </form> </div> </div> </div> models: class Video(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) title = models.CharField(max_length=70) video = models.FileField(upload_to='videos') created_on = models.DateTimeField(auto_now_add=True) banner = models.ImageField(upload_to='banner') slug = models.SlugField(max_length=100, unique=True) class Comment(models.Model): user … -

Django query __in filter on subquery joined over multiple fields without foreignkey
Short: This is the SQL I try to achieve in django: with start_dates as ( select m2.person_id, min(m2.date_current) as start_date from my_table m2 where [...] group by person_id ) select * from my_table m inner join start_dates sd on m.person_id = sd.person_id and m.date_current >= sd.start_date ; Long: There is a table which I need to access twice. The table constists of activities of people. Each people has multiple activities so multiple rows in this table. 1) First access is to find for a set of given filters (like the name of the acitivity and the age of the person) which persons activities fit the filters and per person what is its oldest acitivity fitting the filters. I call that oldest-date "start_date". On SQL this could look like: select m2.person_id, min(m2.date_current) as start_date from my_table m2 where [...] group by person_id With this query I found a sub-set of people with their oldest filtered-activity (so there may be also older activities which do not fit the filters above) Sample A sample would be to find all people ever did taking drugs plus the date when it happened first. 2) Second access is to get for every person found all its … -
login with LinkedIn: Django REST and React.js
I've got problems with authentication with LinkedIn. In my React app, I created LoginButton component following documentation for react-linkedin-login-oauth2. import { useLinkedIn } from 'react-linkedin-login-oauth2'; import linkedin from 'react-linkedin-login-oauth2/assets/linkedin.png'; function Login() { const { linkedInLogin } = useLinkedIn({ clientId: '78j5bjwgkxxxxx', redirectUri: 'http://127.0.0.1:8000/dj-rest-auth/linkedin/', onSuccess: (data) => { console.log(data) }, onError: (e) => { console.log(e) } }); return ( <img onClick={linkedInLogin} src={linkedin} /> ); } export default Login That button is kinda working. As far as I'm understanding, 'redirect_URI' should point backend view, it redirects me to http://127.0.0.1:8000/dj-rest-auth/linkedin/ with code and state. But backend doesn't log me in automatically and manually (I'm trying to paste "code" form URL to "code" in form below.

How to deal with Django Cascade deleted objects in django-simple-history?
I have a problem with django-simple-history when I use cascade deletion on objects. I have several tables in my database that inherit from other tables, so I’ve set the deletion to cascade. The problem is that when I want to query Historical Objects generated by django-simple-history, I do have the one in the parent table, but for objects in the children table, that were automatically deleted by Django, I this error : MyApp.models.parentTable_object.DoesNotExist: parentTable_object matching query does not exist. If I understand the problem, django-simple-history tried to create a Historical object for my deleted object but failed because it needed the parent object it inherited and that no longer exists at this point. I can’t do without cascading so I hope it’s possible because django-simple-history has met all my expectations so far. Thanks you for your help My environment: OS: Windows 10 Browser: Firefox Django Simple History Version: 3.1.1 Django Version: 4.0.3 Database Version: django's integrated SqLite3 -

Choice field validation DRF
Hi all I have my model and its serializer, what I discovered when testing is that serializer is saved no matter what I have in my choice field but in Django admin choice field is empty when the data is wrong and when the data is right I can see the correct option so, -> wrong choice data -> saved regardless -> nothing in django admin -> correct choice data -> saved -> correct value in django admin How can I return validation error if I detect that user posted incorrect data? what I was trying out is topic = serializers.ChoiceField(choices=School.topic) and I don't think that iterating over each tuple and searching for a string is correct or efficient code class SchoolViewSet(viewsets.ModelViewSet): queryset = School.objects.all() serializer_class = SchoolSerializer def create(self, request): serializer = SchoolSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) else: return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) class School(models.Model): SUBJECT = ( ('Math', 'Mathematic'), ('Eng', 'English'), ('Cesolved', 'Chemistry'), ) name = models.CharField(blank=False, max_length=50) subject = models.CharField(choices=SUBJECT, max_length=15, blank=False) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) def __str__(self): return str(f'{self.name} is {self.subject}') class SchoolSerializer(serializers.ModelSerializer): subject = serializers.ChoiceField(choices=School.SUBJECT) def validate(self, data): name = data["name"] if (5 > len(name)): raise serializers.ValidationError({"IError": "Invalid name"}) return data class Meta: … -

Why is Source Control (VScode) asking to commit every single file on my computer to git?
I am trying to create project using Python and Django, using a virtual environment. This is how I set up the project in terminal: cd MyProject python3 -m venv env source env/bin/activate pip install django django-admin startproject (projectname) When I go to open the file in VSCode, source control scans and prompts to commit every single file on my computer (including files in the trash) to Git, to the point where it says "Too many changes were detected. Only the first 10000 changes will be shown below". Why is this happening? I tried right clicking and doing 'discard changes' but it ended up deleting files. -

How do I compare the values gotten from html checkbox to id of same values in database?
I am fairly new to Django and I use the 4.2 version. This is my problem. I am building a blog website, I was trying to add multiple values(tags) for each blog post, from the HTML template checkbox input to my database, which is PostgreSQL. In that database, I already have pre-stored values of items in a Tags table. This table has a ManyToMany relationship with the main Blogpost class. But I am having problems with this particular process. I am trying to add tags for each blogpost created, from the tags already set in the Tags table. The idea is that a user selects the tags they want to include in their blogpost and in the manytomany table, the ids of the tags and the blogpost are set, when the blogpost is saved. I understand that I am to get the id of the values I am trying to add from my database where they exist and include them in the blogpost but I don't exactly know how to do this. This is what my code looks like: models.py class BlogPost(models.Model): id = models.UUIDField(default=uuid.uuid4, unique=True, primary_key='True', editable=False) post_title = models.CharField(max_length=300, blank=True, null=True, verbose_name='Title of blog post') post_image = models.ImageField(upload_to='posts/%Y/%m/%d', … -

How to assertRaises(ValidationError) against Django Rest Framework APIView?
eg. I have my view: class MyView(APIView): def post(...): ... raise ValidationError('blah') And to my test def test_myview(...): factory = APIRequestFactory() request = factory.post('/myview', data=...) with self.assertRaises(ValidationError): MyView.as_view()(request) I get AssertionError: ValidationError not raised I tried to call it and print the result of the call: def test_myview(...): factory = APIRequestFactory() request = factory.post('/myview', data=...) resp = MyView.as_view()(request) print(resp) it's <Response status_code=400, "text/html; charset=utf-8">, so it's kind of correct if I want to test the response code etc, but what should I do if I want to assertRaises instead? -
Cannot access my phpMyAdmin DB - neither any related configuration file
I've been using a phpMyAdmin SQL DB in the past two years, which was pretty transparent to me. I inherited it from a guy that set it up for my team, and I actually got nothing but a username, password, and a Django web project that's linked to that database. Until today, any interaction with that DB was either via Django's ORM, or via the web UI of the phpMyAdmin site. Today, suddenly, for the first time, I got the following error: And that's it. I've been googling this error, and read some stack overflow threads, but they all suggest editing some configuration files in /etc, but again, I have no clue what's that about and how or where do I access those file - all I know is my username and password to the website, and my Django project's ORM queries (I know it's sad, but that's the reality). I'm the only one in the team that uses the DB, so nobody touched nothing for sure. What can I do to fix that, or to start understanding what happened here? Thanks in advance! -

I am making a website with Django that is fed by a database that is refreshed every 3 hours, the problem is that when I want to remove a client from the database, mysql workbench does not let me because the client model is related to notes and user. How can I do so that when a client is deleted, its related classes are automatically deleted?
