JSON API not displaying all values on my HTML
Good day all, I am a newbie programmer, I am working on a website using Django where I use a JSON API I generated online to print the prices of cryptocurrencies. I am having a challenge as my API is not displaying all the values I want it to display on my html. please note that I've checked with console to ensure the API is working correctly and I confirmed it does but the challenge is I cannot seem to understand why I cannot print it out on my HTML. Below is my code that I am using to print the prices. The prices that is showing on my HTML is from Bitcoin to Uniswap while the remaining is not showing. My JAVASCRIPT CODE var btc = document.getElementById("bitcoin"); var eth = document.getElementById("ethereum"); var doge = document.getElementById("dogecoin"); var lite = document.getElementById("litecoin"); var bin = document.getElementById("binancecoin"); var card = document.getElementById("cardano"); var xrp = document.getElementById("ripple"); var pol = document.getElementById("polkadot"); var uni = document.getElementById("uniswap"); var btc_cas = document.getElementById("bitcoin-cash"); var sol = document.getElementById("solana"); var chain = document.getElementById("chainlink"); var poly = document.getElementById("matic-network"); var theta = document.getElementById("theta-token"); var shiba = document.getElementById("shiba-inu"); var vec = document.getElementById("vechain"); var stel = document.getElementById("stellar"); var file = document.getElementById("filecoin"); var aav = document.getElementById("aave"); … -
In Django save multiple filenames (NOT files) for multiple FileFields
In Django I would like to save multiple filenames (NOT files) for multiple FileFields in a Model. I have: 2 Models: One to hold FileFields for different file types (there are identical numbers of files for each type being submitted); the other to hold relevant info of the files. 2 ModelForms: One for each Model. 1 view: To handle the logic for getting filenames from the files and saving them, and discarding the actual file. I have searched many Stack Overflow questions and have derived something that gets me close, but is incorrect. In localhost:8000/admin/ I can see my broken attempt gets me a record for each uploaded file, BUT each record has the same data (the name of the last file in the list for each field). models.py from django.db import models from decimal import Decimal from django.core.validators import FileExtensionValidator # Model for storing related info class RelatedInfo(models.Model): info_name = models.CharField("Name", max_length=255) some_value = models.DecimalField( default=Decimal(0.1), decimal_places=2, max_digits=5 ) X_path = models.CharField(max_length=255, null=True) Y_path = models.CharField(max_length=255, null=True) # Additional fields... # Model for storing filenames class FilesModel(models.Model): related_info = models.ForeignKey( RelatedInfo, on_delete=models.CASCADE ) X_name = models.CharField(max_length=255, blank=True, null=True) X_file = models.FileField( null=True, validators=[FileExtensionValidator(allowed_extensions=["txt"])] ) Y_name = models.CharField(max_length=255, blank=True, null=True) … -
Django REST Framework - return a value from get_queryset?
I am trying to return a value from get_queryset. def get_queryset(self): if self.request.user.is_superuser: return StockPriceModel.objects.order_by('ticker').distinct() elif not self.request.user.is_authenticated: print('in') print(self.request.data) last_price = StockPriceModel.objects.all().filter( ticker=self.request.data['ticker']).order_by('-last_date_time')[0].last_price print(last_price) return last_price last price gets printed without an issue. In return I get various errors: TypeError at /api/stock-prices-upload/ 'float' object is not iterable If I try to return till: StockPriceModel.objects.all().filter( ticker=self.request.data['ticker']).order_by('-last_date_time') It works. As soon as I try to return just the 0 position queryset I get errors. I assume this is because get_queryset is supposed to return a queryset. Not sure how to return just the value. -
Django DRF validate() is not executed with multiple serializer inheritance

How to define custom check according to my rules and how to implement Django
I using Python 3.10, Django 4.1.2, djangorestframework==3.14.0 (front separately) In an order, the products received field is empty by default. As we receive the order, we must remove these elements from the ordered field and transfer them to the received ones. received products must contain only products from requested Products After submitting request with amount of received products, this particular products should be removed from requested Products and addiing to recived_products I have two ideas for a theoretical implementation. Using the patch, the received_product and the elements in it Separate method I have this code: class Orders(models.Model): delivery_model_choices = (("Pickup", "Pickup"), ("Delivery", "Delivery")) order_status_choices = (("Draft", "Draft"), ("Open", "Open"), ("Partially Received", "Partially Received"), ("Received", "Received"), ("Cancelled", "Cancelled")) costumer = models.ManyToManyField(Costumers) products = models.ManyToManyField(Products) recived_products = ??? date_create = models.DateTimeField(auto_now_add=True) delivery = models.CharField(max_length=40, choices=delivery_model_choices) delivery_date = models.DateField() order_status = models.CharField(max_length=40, choices=order_status_choices) total_price = models.CharField(max_length=10) Please, I ask you for a correct example on this implementation.

Django query to find value of objects from previous period (if exists)
I have a simple django project and I am trying to keep track of ranks for certain objects to see how they change over time. For example, what was the rank of US GDP (compared to other countries) over last 3 years. Below is the postgres db structure I am working with: Below is what I am trying to achieve: What I am finding challenging is that the previous period value may or may not exist and it's possible that even the entity may or may not be in the pervious period. Period can be year, quarter or months but for a specific record it can be either of one and stays consistently same for all the years for that record. Can someone guide me in the right direction to write a query to achieve those tables? I am trying to avoid writing heavy forloop queries because there may be 100s of entities and many years of data. So far I have only been able to achieve the below output: I am just trying to figure out how to use annotate to fetch previous period values and ranks but I am pretty much stuck. -
using different serializers Django
hope someone can help me out. I am trying to call different serializes depending on some factors, and one of the factor is if the field called "code" (which is inside MyCards table) is not null then call the rewardsSerializer. the point is that I am not managing to get to get the value of code to see if it's None or not. down here you can see how I have tried to get the value of "code" with no success ''' class MyCardsViewSet(ModelViewSet): serializer_class = MyCardsSerializer queryset = MyCards.objects.all() def get_serializer_class(self): if self.request.GET.get('code') != None: return RewardSerializer if self.action == 'update': return UpdateMyCardsSerializer else: return MyCardsSerializer ''' -

Wagtail SteamFields for community user generated content instead of editor, author workflow
I really like StreamFields, but I don't want the baggage of Wagtail's Publishing system. For example, consider a Forum community site. Instead of using CK Editor or BBCode, Markdown etc form input. I want to give users the option of StreamField based input to construct posts or replies Is this possible? If yes, what steps would I need to take or edits to Wagtail do I need to do? I'm guessing using a permission system while keeping the user as a limited admin would be the thing to do, since removing the user from admin doesn't seem to be possible since Wagtail is heavily reliant on Django Admin. -

How to escape double quotation symbol during lambda apply operation on dataframe column?
I have a pandas column, in which I want to replace the strings with a href hyperlinks that link to a certain url in urls.py when using Django. I managed to get the following: import pandas as pd df = pd.DataFrame(["2022-007", "2022-008", "2022-111", "2022-222", "2022-555", "2022-151"], columns=["column_of_interest"]) df["column_of_interest"] = df['column_of_interest'].apply(lambda x: '<a href=' "{{% url 'columndetails' {0}%}}" '>{0}</a>'.format(x)) This results for example in the following: df["column_of_interest"][0] "<a href={% url 'columndetails' 2022-007%}>2022-007</a>" However, when I run this in Django, and try to get the redirect the following error occurs: Request URL: http://127.0.0.1:8000/%7B%25 The current path, {%, didn’t match any of these.

Django Rest Framework Post API Method Not Working
