How to create a cluster of links, then feed it to scrapy to crawl data from the link based on a depth and crawling strategy set by user from browser
We need help doing this project for our junior year software engineering project. So, our web app is supposed to: Login/Register/Authenticate via google : (we have completed this using Django Allauth.) Then, users will be able to create a cluster of links in a new cluster creating page, there the users will be able to provide information about the clusters. They will provide: cluster name, links to crawl data from, set a depth for each link they provide. (By depth I mean, following the links and webpages associated with the website) Finally, the users will be able to provide a crawling strategy to what to crawl, for this instance(we do not want to crawl any non textual data) : non HTML text data, pdf, doc files. Then, we need to crawl the data and store it in a database or a service (We intend to use Apache Lucene here). So, the data is searchable for the end user from a cluster that they had created. For now, how can we implement all of the things mentioned in point 2? Can someone please help by debunking this step by step on exactly what we need to do? We are a bit … -
Django SECRET_KET on VPS
I'm working on a Djnago app that needs to be uploaded on a VPS. I already have moved my SECRET_KET from settings.py and placed it inside .env file that I created and addedthis .env file to .gitignore.

Validation error in Django 'POST' request
I'm a beginner with Django Rest Framework I've created a model and serializer for it. There it goes: models.py class Car(models.Model): make = models.CharField(max_length=15) model = models.CharField(max_length=15) def __str__(self): return self.make class CarRate(models.Model): rate = models.ForeignKey(Car, related_name='rates', on_delete=models.CASCADE) serializers.py class CarRateSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = CarRate fields = ('rate') class CarSerializer(serializers.HyperlinkedModelSerializer): rates = CarRateSerializer(many=True) '''rates = serializers.PrimaryKeyRelatedField( many=True, read_only=False, queryset=CarRate.objects.all() )''' def create(self, validated_data): rates_data = validated_data.pop("rates") car = Car.objects.create(**validated_data) for rate_data in rates_data: CarRate.objects.create(car=car, **rate_data) return car class Meta: model = Car fields = ('id', 'make', 'model', 'rates') What I want to do is to add a rate for a Car with a specific ID with a POST method and JSON, but when I do it multiple times it stores all the rates for that one object. I will add a rate like that: { "id":2, "rate":4 } So here is my POST method, but it gives a response Car id not found so it doesn't pass validation. views.py @api_view(['POST']) def car_rate(request): if request.method == 'POST': rate_data = JSONParser().parse(request) rate_serializer = CarSerializer(data=rate_data) if rate_serializer.is_valid(): ''' Code that checks if a rate is from 1 to 5 ''' return JsonResponse({'message': 'Car id not found!'}) So what I think might be … -
how to save parent , child and grand child forms in one submit - django
i'm building an application for a mobile trading company , the is the scenario : every invoice has an unique invoice number and every unique date has several phone models and every phone models have a number of IMEI here is how i designed the database model class Collection(models.Model): admin = models.ForeignKey(User,on_delete=models.PROTECT) company = models.ForeignKey(Company,on_delete=models.PROTECT) invoice_no = models.IntegerField(unique=True) collection_date = models.DateTimeField(default=timezone.now) class MobileCollection(models.Model): collection = models.ForeignKey(Collection,on_delete=models.PROTECT,related_name='collections') mobile = models.ForeignKey(ModelCategory,on_delete=models.PROTECT,related_name='model_category') qnt = models.IntegerField() price = models.DecimalField(decimal_places=3,max_digits=20) class Imei(models.Model): mobile = models.ForeignKey(MobileCollection,on_delete=models.PROTECT) imei = models.CharField(max_length=15,unique=True) i have to submit all of them in one go ! i'm not sure how to build its view , while the MobileCollection model should increase dynamically , and with the qnt field in MobileCollection the Imei forms should increase , for example if the qnt=10 we should add 10 Imei forms , i thought about inlineformset_factory but i its not work in my case . please is there a better approach to achieve that ? thank you in advance -

Executing a function right before\after revoking a task in celery
For the demonstration, I have a class that does something like this: class Writer: def __init__(self, num): self.num = num def write(self): for i in range(0, num): with open("/outfile", "w") as o: o.write(i) def cleanup(self): # should be executed when write has not finished os.system('rm -rf /outfile') Im using a shared task in celery to execute it like: @shared_task def mytask(): w = Writer(100) w.write() return "Done" Im using django and DRF, and i have an endpoint api that recieves a task_id and revokes the task using revoke(task_id, terminate=True) My goal is to run the cleanup function from the Writer class when the revoke happens. The reason I cannot just run cleanup after the revoke as a regular function is because it needs to access the attributes of its class (in the real senario and not this example), and each class might have a different cleanup function. how can i detect the revoke in mytask() ? Is there a solution using something like try except? Moving the task to a class based task? Have not found anything online or in the docs. Thanks in advance. -
Django-Rest-Framework can't override serializer unique error_messages

Django - Return all objects in table where attribute A is in list B OR attribute C is in list D
So below I have this code where the request has the current User object. A User can have "followers" which are represented by FollowUser and they can follow another user's goal, which is represented by FollowGoal. I want to return all the posts that the current user which is represented by request.user. I want to be able to get all posts where the creator is someone the current user is following or is a goal the current user is following. As you can see below I generate a list of UUID for both the followees of the current user (people they are following) as well as a list of UUID for the goals the current user is following. Then I do <attribute>__in, but for some reason it's returning an empty list. Even if I just filter by followees or follow goals. Not sure why it's returning an empty list. I generated fake data that represent both the cases of posts created by followees of the current user and goals the current user is following. The Post object should filter if the creator is by someone the current user is following OR the goal is a goal the currrent user is … -

Django - Can't read media files
I'm using Django to create a website where you can upload an image on that website and check if the image contains Moire pattern. Here is the project structure: In file settings.py, I specified the following directory for media files: MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' and in file views.py, I implemented the API that will receive the image and detect moire pattern like this: from django.core.files.storage import default_storage def index(request): if request.method == 'POST': f = request.FILES['sentFile'] response = {} fname = 'pic.jpg' fname2 = default_storage.save(fname, f) file_url = default_storage.url(fname2) image = Image.open(file_url) pred_label = moire_detect(image) response['label'] = pred_label return render(request, 'frontpage.html', response) else: return render(request, 'frontpage.html') However, when I try to open the image using Image module of Pillow, I got this error "No such file or directory: '/media/pic_O1TOyCK.jpg'". I don't really understand what is happening here, because the path is correct. Any help would be really appreciated. -
Add total pages to the Django Rest Framework response when using pagination
At the Django Rest Framework Documentation you can add pagination according to the document at this link: https://www.django-rest-framework.org/api-guide/pagination/#modifying-the-pagination-style class StandardResultsSetPagination(PageNumberPagination): page_size = 100 page_size_query_param = 'page_size' max_page_size = 1000 and the response will look like: HTTP 200 OK { "count": 1023 "next": "https://api.example.org/accounts/?page=5", "previous": "https://api.example.org/accounts/?page=3", "results": [ … ] } How can I add "total_pages" to the response? HTTP 200 OK { "count": 1023 ==>"total_pages": 12 "next": "https://api.example.org/accounts/?page=5", "previous": "https://api.example.org/accounts/?page=3", "results": [ … ] } I looked into the DRF code and saw the PageNumberPagination class has a "num_pages" property. But I'm not sure how to call it in the StandardResultsSetPagination class. https://github.com/encode/django-rest-framework/blob/0323d6f8955f987771269506ca5da461e2e7a248/rest_framework/pagination.py
