Can't enable HSTS on Django Application
I've been working on a Django web application and I'm trying to increase its security level from A to A+ on the SecurityHeaders website (https://securityheaders.com/). The only thing I seem to miss is the "Strict Transport Security" header. That's the only reason I get an A. I saw that the HSTS Headers can be easily added in Django using some settings parameters. After reading some stuff online, I added these lines of code in my settings.py: SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') SECURE_HSTS_SECONDS = 60 SECURE_HSTS_INCLUDE_SUBDOMAINS = True SECURE_HSTS_PRELOAD = True (...) but when navigating on my site, I don't see the Strict Transport Policy header in the Response section (when pressing F12). This is how my Response looks like: alt-svc: h3=":443"; ma=86400, h3-29=":443"; ma=86400, h3-28=":443"; ma=86400, h3-27=":443"; ma=86400 cf-cache-status: DYNAMIC cf-ray: 6c9ba77f4c128bbd-FRA content-security-policy: default-src 'self' 'unsafe-inline'; img-src 'self' 'unsafe-inline' data:; connect-src 'unsafe-inline' *.fontawesome.com; object-src 'self' 'unsafe-inline'; font-src 'self' 'unsafe-inline' *.fontawesome.com fonts.gstatic.com; style-src 'self' 'unsafe-inline' *.fontawesome.com *.w3.org maxcdn.bootstrapcdn.com fonts.googleapis.com; script-src 'self' 'unsafe-inline' https://use.fontawesome.com https://kit.fontawesome.com *.jquery.com *.cloudflare.com *.jsdelivr.net content-type: text/html; charset=utf-8 cross-origin-opener-policy: same-origin date: Fri, 07 Jan 2022 08:00:46 GMT expect-ct: max-age=604800, report-uri="https://report-uri.cloudflare.com/cdn-cgi/beacon/expect-ct" location: / nel: {"success_fraction":0,"report_to":"cf-nel","max_age":604800} permissions-policy: accelerometer=(), ambient-light-sensor=(), autoplay=(), camera=(), display-capture=(), document-domain=(), encrypted-media=(), fullscreen=(), geolocation=(), gyroscope=(), interest-cohort=(), magnetometer=(), microphone=(), midi=(), payment=(), … -

Hello i need to know how to represent an object with this specific in django models
I'm creating a web app based on Django for inventory system and i have an object with this specific: I have a Box that contains : class PalletN(models.Model): qr_type=models.CharField(max_length=50,blank=True,null=True) customer_partnum=models.CharField(max_length=50, blank=True,null=True) partsnum=models.CharField(max_length=50, blank=True,null=True) boxquantity= models.IntegerField(default='0',blank=True,null=True) Ponum =models.CharField(max_length=50,blank=True,null=True) designation= models.CharField(max_length=50, blank=True,null=True) production_date=models.DateField(blank=True , null=True) suplier=models.CharField(max_length=50,blank=True,null=True) shipment_date=models.DateField(blank=True, null=True) Customer_code= models.CharField(max_length=50,blank=True,null=True) Snumber= models.CharField(max_length=50,blank=True,null=True) status=models.CharField(max_length=20,blank=True, null=True) creation_date=models.DateField(auto_now_add=True) zone=models.ForeignKey(zone,on_delete=models.CASCADE, null=True) rack=models.ForeignKey(rack,on_delete=models.CASCADE, null=True) position=models.ForeignKey(position,on_delete=models.CASCADE, null=True); My problem is how to represent a Mixt Pallet meaning a mixt pallet can have multiple customer_partnum designation and so on. i'm reading the data using a Qr code and this an example for better understanding. Pallet Normal: QR|XX5125B219|2021/07/13|2021/08/26|XXX2125-B|XX-T4311311E-4IX|XX-T43-11311-E-XXX|Some description|300|40|12000| Pallet Mixte: QR|XX5125B182|2021/07/13|2021/08/26|XXX2125-B| XX-L8814313A-9PX|XX-L88-14313-G-XXX|Some description|1000|12|12000| XX-L8814314A-9PX|XX-L88-14314-G-XXX|Some description|1000|13|13000| XX-L8814316E-9PX|XX-L88-14316-E-XXX|Some description|1000|15|15000| in the case of pallet mixte i have a lot of references for the user to add a new mixte pallet it's a bit chalenging to choose between them if i a do a drop down menu it will contain like 200 and plus reference and as i told you befor a mixte pallet can have 2 or plus references. I would love your sugestions if that's possible THANK YOU -
REST API Django Authentication does not return refresh in package Simple Rest

Django - settings.DATABASES is improperly configured. Please supply the ENGINE value
I've got a postgres DB which Django successfully connects to but when trying to create a new model I'm getting the error settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details. I know settings.DATABASES is correctly configured as I've already created models which then Django used to create tables in the DB but for whatever reason it is now causing this error. You can also see that I have already "supplied the ENGINE value". DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': os.environ['POSTGRES_DB'], 'USER': os.environ['POSTGRES_USER'], 'PASSWORD': os.environ['POSTGRES_PASSWORD'], 'HOST': 'db', 'POST': '5432', } } All help is appreciated. -

Is there a way to render a React component *UI* into Django without calling APIs?
I've been working on my Django App for a couple of months now and decided to use React as my front-end, which I know is bad habit for development and makes everything a lot more complicated. I run npm build for my front-end app with Django, but when I launch the Django Project, it shows me the Django Rest Apis. When I wanted it to show me my UI, I built in React. Everything in my Django settings should be correct from tutorials and documentations, so I believe that isn't the issue. I've tried calling the my API's but I believe that isn't the issue either. I am trying to keep everything as simple as possible, so if I'm missing stuff in my code I apologize, I just want to understand the very basics of React without having a lot of side code. Here is my App.js import React from 'react'; import './App.css'; import Form from './Form'; class App extends React.Component { render(){ return( <Form /> ) } } export default App; index.js import React from 'react'; import ReactDOM from 'react-dom'; import App from './App'; ReactDOM.render( <React.StrictMode> <App /> </React.StrictMode>, document.getElementById('root') ); -

How to restore integers from my json.dumps file (for display in my javascript chart) when using Django
In my Django application, I have a very basic Pie Chart model with the name column as a CharField and the stats column as an IntegerField. I also have some javascript code on my html page that displays a pie chart -- but I'm only able to get it working if I hardcode the values as an array. I was hoping to instead display the data from my model/ DB as {{ values|safe }} in pie chart form, pulling the values from json dumps of my DB data. Here's what I've tried, as seen in my views.py file: def metrics(request): pietitle = serializers.serialize('json', PieChart.objects.all(),fields=('title')) piestats = serializers.serialize('json', PieChart.objects.all(),fields=('stats')) piedata=[[pietitle, piestats]] json_data = json.dumps(piedata) data_json= json.loads(json_data) return render(request, "metrics.html", {"values": data_json}) On my HTML page, the message I'm getting is simply "No Data", and I'm fairly certain that's because when I serialize the stats field, it's converted to a string and is unable to be interpreted as integers. Would anyone kindly be able to assist? Thanks so much, in advance. -

React .map function not working after Django backend GET with axios
I am trying to make a simple React frontend while using Django Rest Framework as a backend. When I make the call to Django and then try to use the .map function to display the data, I get an "Uncaught (in promise) TypeError: this.state.users.map is not a function". I am a React noob so it is definitely something I am doing. import React from 'react'; import axios from 'axios'; class App extends React.Component { state = { users: [] } componentDidMount() { axios.get('http://127.0.0.1:8000/api/users/') .then(res => { const users = res.data; this.setState({ users }); }) } render() { return ( <ul> { this.state.users.map(user => <li>{user.username}</li>)} </ul> ) } } export default App; -

How do I remove the ticks or inner circles of my polar area chart Chart.js
I have written the code for my chart in Jquery and I am using the chart to display data on my Django Web Page, I want to remove the inner circles which I think are called ticks along with the small numbers that are displayed with them. I have tried to use the ticks:{ display: false, } and scale:{ display: false, } but have had no luck with either I am not sure how to do it. Code for Chart: new Chart("chart_{{ i.pk }}_{{ t.pk }}", { type: "polarArea", data: { labels: labels_{{ t.pk }}, datasets: [{ fill: true, pointRadius: 1, {# borderColor: backgroundColors_{{ t.pk }} ,#} backgroundColor: backgroundColors_{{ t.pk }} , data: totals_{{ i.pk }}_{{ t.pk }}_arr, }] }, options: { responsive: false, maintainAspectRatio: true, plugins: { legend: { display: false, }, scale: { ticks: { display: false, }, gridLines: { display: false, lineWidth: 7, tickMarkLength: 30// Adjusts the height for the tick marks area }, }, title: { display: false, text: 'Chart.js Polar Area Chart' } } } }); {% endfor %} {% endfor %} {% endblock %}
