Is there a way to type the elements of the dictionary that is returned by a serializer?
I use the serializers that come from django-rest-framework to validate many of the request on my app end. I have found thhat is very useful to get the objects on the serializer, but the dictionary the serializer returns with the serializer.validated_data is not typed This is how I perform the validation: On views.py def post(self, request): body_serializer = ExampleSerializer(data=request.data) body_serializer.is_valid(raise_exception=True) body_data = body_serializer.validated_data # to get the object object_one = body_data['object_one'] On the serializers.py class ExampleSerializer(serializers.Serializer): field_one = serializers.CharField(required=True, help_text='field_one') field_two = serializers.CharField(required=True, help_text='field_two') field_three = serializers.CharField(required=True, help_text='field_three') def validate(self, attrs): object_one:ObjectOne = ObjectExample.objects.get(field=field_one) attrs['object_one'] = object_one return attrs Is there a way I can type the return dictionary? -

What is the correct way to end a Watchdog observer without a sleep loop?
I am relatively new to python and programing in general. This is my first question on Stack Overflow so thank you for any responses in advance! My question is this. I have a Python web application that is using the django framework. A new feature of that web application requires the use of a locally installed command line tool on the server, that tool dumps an output file to a directory previously created. I want to watch that directory and when a file is created in it that ends in .json call a parsing function. Enter the Watchdog library. I have followed a number of tutorials/checked on here for how to correctly setup an observer. They all have the observer being started and then immediately going into a time.sleep(1) loop while waiting for something to happen. However since this is a django webapp I don't want to sit and wait while the watchdog observer is looking for the file to be created. Here is an example code from Geeks for Geeks: if __name__ == "__main__": # Set the format for logging info logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(message)s', datefmt='%Y-%m-%d %H:%M:%S') # Set format for displaying path path = sys.argv[1] if len(sys.argv) > … -
No module named 'manage_db.tools'; 'manage_db' is not a package
I have a Package that works with the Django Framework. I'm trying to import two packages that are outside the Django package, so that I can work with their Python files. In order for Django to recognize the packages, I added the following lines to the Django settings file: manage_db = os.path.join(BASE_DIR.parent.parent, "manage_db") g = os.path.join(BASE_DIR.parent.parent, "g") sys.path.append(manage_db) sys.path.append(g) And in the views.py file I wrote: from g.globals import Globals from manage_db.tools import Tools The error I got is: For the first package - No module named 'manage_db.tools'; 'manage_db' is not a package For the second package - No module named 'g' . I read from people who had similar problems that they changed the names of the directories, and it worked for them, I tried, and I change the name to "g", but it didn't work. Note: I created the packages, they are not packs that require pip install Thanks in advance to all the helpers. -

create new objects from list only if its not in django database
I am having a list of python objects. suppose py_objs_list = [...data...] Model is Card I want to create a new object in django database only if database already dont have object My solution is to do objects.all() on my Card and run a for loop on py_objs_list and check if py_obj in objects.all(). If not present im taking that py_obj into seperate list. Finally creating objects using bulk_create py_objs_list = [...data...] cards = list(Card.objects.al()) <--- i know db hits here ---> emails = [card.email for card in cards] <--- does db hit here also everytime in a loop ---> empty_list = [] for py_obj in py_objs_list: if py_obj[some_data] not in emails: empty_list.append(py_obj) ---bulk_create--- Is this the best way to tackle this problem? pls tell me if not (want the best one). thnks:) Now my doubt is does db hit everytime in list comprehension as mentioned above my solution for this problem -
'Category' object is not subscriptable Django
I am learning Django. I wrote a simple model and some views method in Django rest framework so that I can modify some particular attributes when needed to all the records that need that. Here is the model: from django.db import models class Category(models.Model): name = models.CharField(max_length=255) isActive = models.BooleanField(default=True) def __str__(self): return self.name Then, I created this view to modify the isActive session when I call it: class CategoriesChangeActiveView(views.APIView): def post(self, request, format=None): try: categories = request.data.get('categories') for category in categories: category = Category.objects.get(id=category['id']) category.isActive = category['isActive'] category.save() except Exception as e: return Response({'error': 'Bad request'}, status=status.HTTP_400_BAD_REQUEST) return Response({'success': 'Active changed'}, status=status.HTTP_200_OK) Even when the format of my request is correct ( I debugged each line ) when it comes to the line category.isActive = category['isActive']it throws the error that'Category' object is not subscriptable`. I don't know why or how to fix it. I saw in the official documentation, on older StackOverflow questions that this is doable, but I don't understand why I can't. Can someone please suggest what I am doing wrong? Thank you -
How to improve search faster inside json file?
Here I have a sample JSON file with size more than 10MB(which will increase eventually). I have a python function which will try to match the entire json object from the json file and if matches it returns the next json object. This is my current implemention.It does the work but not sure it is the right way. I want some suggestions so that I can make this function much faster and scalable since this function is going to be used in several rest apis. { "all_checks": [ { "key":"value", "key2": { "key": "val" } }, { "key":"value", "key2": { "key": "val" } }, { "key":"value", "key2": { "key": "val" } }, ] } python func import os import json from django.conf import settings def get_value(value): with open(os.path.join(settings.BASE_DIR, "my_json.json")) as file: data = json.load(file) # for i,v in enumerate(data["all_checks"]): # if json.dumps(value) == json.dumps(v): # return data["all_checks"][i + 1] ls = [data["all_checks"][i + 1] for i, v in enumerate(data["all_checks"]) \ if json.dumps(value) == json.dumps(v)] return dict(ls[0]) This function will be used in several apis -

Why does my registration form not work ? (Django Framework)
I am creating a website using Django. Somehow I cannot register as a user as I always get the following error message: UnboundLocalError at /register/ local variable 'context' referenced before assignment views.py def register(request): if request.method == 'POST': form = UserRegisterForm(request.POST) pform = UserProfileForm(request.POST) if form.is_valid() and pform. is_valid(): user = form.save() profile = pform.save(commit=False) profile.user = user profile.save() username = form.cleaned_data.get('username') messages.success(request, f'Your account has been created! You are now able to login') return redirect('login') else: context = { 'form': UserRegisterForm, 'p_form': UserProfileForm } return render(request, 'users/register.html', context) register.html {% load crispy_forms_tags %} {% block content %} <div class="content-section"> <form method="POST"> {% csrf_token %} <fieldset class="form-group"> <legend class="border-bottom mb-4">Join Today</legend> {{ form|crispy }} </fieldset> <div class="form-group"> <button class="btn btn-outline-info" type="submit">Sign Up</button> </div> </form> <div class="border-top pt-3"> <small class="text-muted">Already have an Account? <a class="ml-2" href="{% url 'login' %}">Sign In</a></small> </div> </div> {% endblock content %} Does anyone have an idea why my context is false or won't be accepted ?
