Django: Calculate with "models.TimeField"
Good day and a happy easter-weekdend, in Django I'm trying calculate inside my "models.py" with the amounts of multiple TimeField. For example: class Times(models.Model): ... time_from = model.TimeField() time_to = model.TimeField() time_break = model.TimeField(default='00:00:00') time_all = ... ... Let's say my times look like... time_from: 08:00:00 time_to: 14:30:00 time_break: 00:30:00 ... I want to achieve the time of "06:00:00" inside my variable "time_all" Does anyone have an idea? Thanks! -
Django REST, append new field from values in a list
In a view, I get the result of an image classifier as a dictionary containing the name of an animal as key and the probability of it being the correct animal as value. {'dog': 0.9, 'wolf': 0.1} From here I send a Response containing all the animals of the dictionary that are also in the Animal Model. [ { 'common_name': 'dog', 'scientific_name' : 'Canis lupus familiaris', }, ] I would like to add the probability value for each occurrence contained in the dictionary : [ { 'common_name': 'dog', 'scientific_name' : 'Canis lupus familiaris', 'probability' : 0.9, }, ] What would be the best strategy for that? Here I am so far: Views.py: class AnimalListCreateAPIView(APIView): def get(self,request): classifier_result={'dog': 0.9, 'wolf': 0.1} list_animals=list(classifier_result.keys()) animals = Animal.objects.filter(common_name__in=list_animals) serializer = AnimalSerializer(animals, many=True) return Response(serializer.data) Serializers.py: class AnimalSerializer(serializers.ModelSerializer): class Meta: model= Animal fields= [' common_name ',' scientific_name '] Models.py class Animal(models.Model): common_name = models.CharField(max_length=50) scientific_name = models.CharField(max_length=50) def __str__(self): return self. common_name -
Verifying a Google ID Token in Django
I have a React Native Android app which uses Google Sign-In to get the users profile and email information and produces an ID token (using https://github.com/react-native-community/google-signin). The sign in works and I am displaying the users name, email, photo etc on the app. I am then trying to send the ID token to a Django + DRF backend so that it can be validated and a relevant user account created and/or logged in. I am following the instructions here: https://developers.google.com/identity/sign-in/web/backend-auth Here is my code for the endpoint. For now I have just been copying the ID token produced by the app and sending it to the backend via Postman. class GoogleView(APIView): def post(self, request): token = {'idToken': request.data.get('idToken')} print(token) try: idinfo = id_token.verify_oauth2_token(token, requests.Request(), MY_APP_CLIENT_ID) print(idinfo) if idinfo['iss'] not in ['accounts.google.com', 'https://accounts.google.com']: raise ValueError('Wrong issuer.') return Response(idinfo) except ValueError: # Invalid token content = {'message': 'Invalid token'} return Response(content) When I send the POST request, the first print statement runs confirming that the token was received correctly. However the second print statement never runs and I always get the 'Invalid token' response. So, I believe verify_oauth2_token is failing somehow but it doesn't give me anymore information. I have never used … -

Djngo Formset: ['ManagementForm data is missing or has been tampered with']
I tried to implement inline forms using Django's formsets. To explain what I've tried to do is, I've tried to take multiple orders for a particular customer. I'm sharing the code for the same. views.py def create_customer_order(request, pk): OrderFormSet = inlineformset_factory(Customer, Order, fields=('product', 'status')) customer = Customer.objects.get(id=pk) if request.method == 'GET': formset = OrderFormSet(instance=customer) context={'customer': customer, 'formset': formset} return render(request, 'customer_order_form.html', context=context) elif request.method == 'POST': formset = OrderFormSet(request.POST, instance=customer) if formset.is_valid(): formset.save() return redirect('/') and my customer_order_form.html is, {% extends 'main.html' %} {% load static %} {% block content %} <h3>Orders for {{ customer.name }}</h3> <br> <form method="POST" action="."> {% csrf_token %} {{ formset.management_form }} {% for form in formset %} {{ form }} <hr> {% endfor %} <input type="submit" name="Submit"> </form> {% endblock %} But when I'm making a POST request, i.e. to save the multiple forms (in the formset), I'm getting the following error.

Django Saving Calculated Value to Model
:) I'm a Django beginner and I'd like to ask for some help from you beautiful people. Here's what I'm trying to accomplish: I have a model - shown below -that I would like to contain a score for each symbol. class Stock_Score(models.Model): Symbol = models.CharField(max_length=20, null=True) Score = models.FloatField(null=True) To calculate that score, I'd like to use a second model which contains a list of stocks and a value called Yrs for each symbol: class Stock_Data(models.Model): Symbol = models.CharField(max_length=20, null=True) Yrs = models.FloatField(null=True) So what I was thinking was to import the Stock_Data model in my views.py, loop through the Symbols, check a simple if/else and then save the result to my first model under the "Score" field. Something like this: data = Stock_Data.objects.all() for i in data: if i.Yrs > 10: Score = 1 else: Score = 0 Score.save() Apologies for this garbage code, but I'd love some ideas about how I would be able to accomplish this :) Thanks in advance. -

Django User uploaded JPG not being visualized
OK, I've wasted a lot of time on this one and read a lot of other threads on this: I want to visualize a user uploaded profile pic. I'm still on a development server on windows. I can visualize static jpg without any issues. The uploading goes correctly: the jpg is stored in the media folder, but when I try to visualize the jpg, I only get the default jpg icon and a 404 error. I have no idea what's going wrong.

Is there a way to avoid recalculating some values in a recursive many-to-many relationship using django and graphene?
Let's say I have a recursive a many-to-many relationship on one of my Django models, and I'm using graphene_django to query a tree. Something like this: query getTree{ tree{ id active percentage children{ id active percentage children{ ... } } } } Where 'percentage' is a value based on how many of the node's children are active. I could calculate the percentage on each node on their own, but then a bunch of nodes would be calculated multiple times. Is there a way to avoid this? -
Python Django log in with encrypt/decrypt messages
I've used this source code https://github.com/sibtc/simple-django-login. Before logging in I want to display encrypted messages on the log in page, and when logged in I want these messages to be decrypted. I also want the user who is logged in to be able to post another message to these already displayed messages. I will have txt files that will consist of the messages that will be displayed, so when a user posts a new message it will be added to this. I know each time the program is run them posts will be lost but thats okay for what I am currently looking for. The file system the program simple-django-login has slightly confused me as I'm unsure where I should put my python encrypt.py file which will handle the encryption. Any help with this project would be helpful like a drafted encrypt.py file and where it should be placed. Or inputting a form on the html and referencing when a message is posted where should the submit button redirect you. Thanks in advance -

How can I change the returned field metadata type in the json returned by OPTIONS using the Django REST Framework?
I am currently writing an automated script to extract metadata types from my models in Django endpoints which I am trying to hook up to swift. How to pass information about the field data type to the frontend when using Django Rest Framework? The previous question on stack exchange explains how the OPTIONS field can be used to extract the metadata from my models; however, I run into a problem in that not all fields returned are detailed. Particularly, foreign key fields do not specify the correct metadata type. for instance, "created_by_merchant": { "type": "field", "required": false, "read_only": true, "label": "Created by merchant" } "item_size_selection": { "type": "field", "required": false, "read_only": false, "label": "Item size selection" } Both are foreign keys. Created by merchant should be an integer, item_size_selection should be a charfield. Is there any way I can specify the type for particular fields in my OPTIONS? -

I would like to pass one of the models to a function, and then have the function traverse the ManyToManyField to display the related model's fields. class Email(models.Model): subject = models.CharField(max_length=50) body = models.TextField() time_sent = models.DateTimeField(null=True, blank=True) recipients = models.ManyToManyField(Email, related_name='emails') class Contact(models.Model): email_address = models.EmailField() contact_name = models.CharField(max_length=50, null=True, blank=True) The end result would be something like: >>> get_fields_of_related_model(Email) {'recipients': {'email_address': 'EmailField', 'contact_name': 'CharField'}} >>> get_fields_of_related_model(Contact) {'emails': {'subject': 'CharField', 'body': 'TextField', 'time_sent': 'DateTimeField', 'recipients': 'ManyToManyField'}}
