How to access a JSON variable via a POST response in Django?
I have JSON data is coming in via POST. The data I am sending is via JavaScript const items = [{ id: "T-shirt" }]; async function initialize() { const response = await fetch("/getorder/", { method: "POST", headers: { "Content-Type": "application/json" }, body: JSON.stringify({ items }), }); On the python side in my view, I can access items fine: return HttpResponse(data.get("items")) Which returns {'id': 'T-shirt'} My problem is accessing just the value for the 'id' key so I can assign 'T-shirt' to a variable. So far I have tried tried: Using data.get('items')['id'] which returns: "list indices must be integers or slices, not str" Using data.get('items')[id]` returns: list indices must be integers or slices, not builtin_function_or_method Using data.get('items')[0] returns 'id', but I still can't access the matching item. Using data.get('items')[1] returns list index out of range Using data.get('items')[0[0]] returns type int not subscriptable Using data.get('items')[0]['id'] returns just 'id' How can I just access 'id' to assign the value 'T-shirt' to a variable? -
Unclear how to set __package__ variable
I have a Django project that I've been working on for a while. I came to the point where I wanted to load a significant amount of data into my Postgres database. I set aside a new Django project with sqlite3 just to work out the code and run some tests to make sure everything was inserted properly. Everything seemed fine until I got to the point where I actually wanted to test the insert script. ImportError: attempted relative import with no known parent package The error refers to this line in the script: from .models import Statute As of right now, this has no red squiggly line on it. models.py and this script are right beside each other in the same directory: $ tree └── parsecodetree ├── db.sqlite3 ├── manage.py ├── parsecodetree │ ├── asgi.py │ ├── __init__.py │ ├── settings.py │ ├── urls.py │ └── wsgi.py └── ustitles ├── admin.py ├── apps.py ├── __init__.py ├── insert504.py ├── insert_script_results ├── migrations ├── models.py ├── t10p1b.html ├── tests.py └── views.py I found this trick in an old David Beazely video: parsecodetree/ustitles/__init__.py: from .models import * print("This is ustitles.__init__") “This is ustitles.__init__” does not print.

Django Time Series with Chart JS
I'm building a Django app that is dynamically feeding data to Chart JS. because I'm trying to join two line series together (historical values and predictions), I'm trying to have Chart JS understand NaN. This is how the code is written: <script> new Chart(document.getElementById("chart"), { type: 'line', data: { labels: {{ new_dates|safe }}, datasets: [ { data: {{ orig_val|safe }}, label: "Historical Sales", borderColor: "#3e95cd", fill: false }, { data: {{ preds|safe }}, label: "Predictions", borderColor: "#22DD66", fill: false } ] }, options: { title: { display: true, text: 'output chart' }, maintainAspectRatio: false, responsive: true, scales: { xAxes: [{ gridLines: { display:false } }], yAxes: [{ gridLines: { display:false } }] }, animation: { duration: 2000, }, } }); </script> This is what the console sees: <script> new Chart(document.getElementById("chart"), { type: 'line', data: { labels: ['2019-01', '2019-02', '2019-03', '2019-04', '2019-05', '2019-06', '2019-07', '2019-08', '2019-09', '2019-10', '2019-11', '2019-12', '2020-01', '2020-02', '2020-03', '2020-04', '2020-05', '2020-06', '2020-07', '2020-08', '2020-09', '2020-10', '2020-11', '2020-12', '2021-01', '2021-02', '2021-03', '2021-04', '2021-05', '2021-06', '2021-07', '2021-08', '2021-09', '2021-10', '2021-11', '2021-12', '2022-01', '2022-02', '2022-03', '2022-04', '2022-05', '2022-06', '2022-07', '2022-08', '2022-09'], datasets: [ { data: [71.0, 67.0, 84.0, 65.0, 78.0, 74.0, 73.0, 88.0, 86.0, 77.0, 94.0, 123.0, 71.0, 77.0, 57.0, … -

Django: template to list data from 2 models related each other
I have 2 models.

One of them were the following template and view: <h2>List of Products</h2> <ul> {% for product in list_of_products %} <li>product: {{ product.name }} &emsp; &emsp;power: {{ product.power }}W &emsp; price: {{prices.product.price }} $</li> {% endfor %} </ul> def index(request): products = Product.objects.all() prices = Price.objects.all() return render(request, "index.html", {'list_of_products': products, 'prices': prices}) Thank you for any help in solving my problem. -

How to validate data in nested ModelSerializer?

How would I go about creating a Django + SvelteKit webapp?
I've already gotten my fair share of Bootstrap and Django but never tried out other frontend frameworks like Angular, React, etc. and finally wanted to try SvelteKit. So I'm really inexperienced and new with this sort of stuff. Currently I've already set-up my Django project as well as a SvelteKit project by following the tutorial on their website. My problem is that I'm confused about how to combine Django and SvelteKit now. Do I just run both servers simultaneously on different ports and get the data from Django JSON APIs into my Svelte frontend or is there some kind of approach to this? I thought that maybe there's a way to get my Django app to render the Svelte files from the Svelte server for me. I just feel really lost at the moment so if anyone could help me or has some resources I could read to get more familiar with the topic, since I didn't find a lot online, that'd be great! Many thanks in advance! -

How to use load model in TensorFlow with Django quickly
I have a Django API that makes predictions using a TensorFlow model. The first time the model loads it takes Django up to 12 seconds. In production, this is unacceptable. How can I speed up the loading of my TensorFlow model for use in Django? This is how I load Django: from tensorflow.keras.models import load_model model = load_model('test/models/test', compile=False) model.predict(padded) I read that compile=False might speed things up, but it doesn't. My Django app only uses the predict function as the model is simply handed to me and trained elsewhere. Simply importing tensorflow.keras.models is where it takes all the time. -

One to One vs Many to One
I'm thinking of storing event and event location but I'm wondering about how should I do it. Because many events can be hosted at a single event location. And just to inform we are going to take event location information by a map most probably longitude and latitude (#if possible textual address as well") Now the questions is how should I go about it Shall i store the address in the same table of event Shall i create a event and address table seperately and have a relationship as oneToOne field Or should I keep the event and address table seperately but have the relationship as foreign key (Note in the last method I think it can potentially reduce the amount of data that I need to store but I'm scared that it could bring a lot of complications when dealing with lot of data ) Please if you tell which is better way of doing it please mention why it is better Any help or guidance will help me great deal , Thank you in advance -
Is it possible to create django passwords using php?
I'm trying to use php to create password hashes acceptable by django, i tried using php function "hash_pbkdf2" and then "base64_encode", then making it into django's password format ( algorithm$iterations$salt$hash ). i also used 320000 iterations (same as django) and created a random string for salt. $n=22; function getName($n) { $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'; $randomString = ''; for ($i = 0; $i < $n; $i++) { $index = rand(0, strlen($characters) - 1); $randomString .= $characters[$index]; } return $randomString; } $pass = "erf1377"; $iterations = 320000; $salt = getName($n); $hash = hash_pbkdf2("sha256", $pass, $salt, $iterations); $hash = base64_encode($hash); $final_hash = "pbkdf2_sha256$".$iterations."$".$salt."$".$hash; echo $final_hash; (getName() creates my salt) but the end result is not accepted by django. what am i doing wrong here? -

How to solve in Django REST API the serializing of data from 2 models with ForeignKey
I was wondering what the correct way is to serialize data in Django REST API from 2 models connected with ForeignKey. The situation is: i have a 1st table called NewUsers with the user registrations, and a 2nd table called Ticker with data saved from an external API. The goal is: create a 3rd table with parts of the 2 tables interconnected - one part is the user loggedin, and the other part is the selection of one crypto object. This new table will then be displayed via Django REST API serializer. The problem is: this new 3rd table does not display the complete list of values selected by the user.
