Django - Foreign Keys and the Admin Page
Preface: I've been scouring stackoverflow but have found a solution - please point me in the correct direction if one does exist. I am trying to display the foreign key relations on the admin change page (i.e. the www.some.url/admin/<app>/<model>/<id>/change/ page): I have two models linked together via a foreign key relationship like so: # models.py class Bank(models.Model): name = models.CharField(max_length=100) class Branch(models.Model): bank = models.ForeignKey('Bank', on_delete=models.CASCADE, related_name='branches') name = models.CharField(max_length=100) And I have a model-admin like so: # admin.py class BankAdmin(admin.ModelAdmin): list_display = ('id', 'name',) How can I add the list of branches associated to a given bank on the django-admin-change page? Can I add something to my BankAdmin class that will achieve this? i.e. If I were to visit the admin page and click on a bank instance (i.e. www.some.url/admin/<app>/bank/2/change/) I would like to see the name of the bank and all of its foreign-key related branches. -
Stripe Checkout Client-only integration with Django
My goal is to integrate a Stripe Checkout Client-only integration with a Django app using these instructions. I copied the code provided by stripe into a html template. When I run the template, the checkout button appears but the stripe script is not executed when the button is clicked (no errors). I expected to be redirected to the stripe checkout page. I have tried moving the javascript to separate files in the static folder with the same result. Is the issue linking the button click to the javascript? Here is the html template with the stripe code inserted: {% load static %} <!DOCTYPE html> <html lang="en" dir="ltr"> <head> <title></title> <!-- Load Stripe.js on your website. --> <script src="https://js.stripe.com/v3"></script> </head> <body> <!-- Create a button that your customers click to complete their purchase. Customize the styling to suit your branding. --> <button style="background-color:#6772E5;color:#FFF;padding:8px 12px;border:0;border-radius:4px;font-size:1em" id="checkout-button-sku_GyczP1qEmsj6eZ" role="link" > Checkout </button> <div id="error-message"></div> <script> (function() { var stripe = Stripe('pk_test_yWdjuG9EAuGjwpVenyzR6Ykn00AsFHsmGC'); var checkoutButton = document.getElementById('checkout-button-sku_GyczP1qEmsj6eZ'); checkoutButton.addEventListener('click', function () { // When the customer clicks on the button, redirect // them to Checkout. stripe.redirectToCheckout({ items: [{sku: 'sku_GyczP1qEmsj6eZ', quantity: 1}], // Do not rely on the redirect to the successUrl for fulfilling // purchases, customers may … -
adding a new column to postgres db django
I am trying to add a new column to an existing table with django in my postgres db. I did python3 makemigrations and python3 migrate but the new column does not appear. I also cleared migrations. It would still say the column does not exist on the db. The only workaround is to manually enter it in commandline or clear the whole database and start from scratch. Is there another alternative? -
Querying BigQuery Dataset from Django App Engine
I have data stored in BigQuery - it is a small dataset - roughly 500 rows. I want to be able to query this data and load it in to the front end of Django Application. What is the best practice for this type of data flow? I want to be able to make calls to the BigQuery API using Javascript. I will then parse the result of the query and serve it in the webpage. The alternative seems to be to find a way of making a regular copy of the BigQuery data which I could store in a Cloud Storage Bucket but this adds a potentially unnecessary level of complexity which I could hopefully avoid if there is a way to query the live dataset. -
updating values in django template in html input?
i am making a shopping cart , i want to update the value as the user updates the input field.. here is my code.. `<tr> <th scope="row">1</th> <td>${object['name']}</td> <td><input type="number" value=1 id=${object['id']}></td> <td>${object['price']*this.value}</td> </tr>`; the input field has a default value of 1. In the last tag i am multiplying value by the price. i am using "this" keyword because i want to apply the multiplied amount to the same row. It doesn't give me any error but it just prints "NaN" in the table not the figure. -
Is there any security issue while giving only "select" and "insert" permissions on all tables with psycopg2?
I think that writing a python script that includes admin credentials for postgresql database is not secure way. So I am trying to add another side: Django web server. But I have concerns yet again. I wanted to increase security by giving only "select" and "insert" permissions to a user and giving all other jobs (creating table, updating, again inserting) to a Django server. But I've started to think it's a bad idea. However I don't have another idea to do it securely. What do you think about that? -

OpenCV videocapture returns False when calling isOpened(), although, another code example works well
So, I have a Django app, that manages some USB webcameras(all Logitech C525) This app takes frame from a VideoCapture object, when the GET request comes on specified API-endpoint and sends this frame to a server, to do some classification of object on image (usually fruits/vegetables) App receiving requests from clients, each client's IP address(app and clients are in the same local network) is binded to unique webcam ID Here's a snippet, that shows, how I'm searching binding between camera ID and logical device in /dev/video* to create a VideoCapture object: import re import subprocess class CameraBinder(object): def __init__(self): self.cam = 'C525' self.cam_id_list_in_dev_video = [] self.binding_between_udev_dev = None def find_cam_in_dev_video(self): cmd = ['/usr/bin/v4l2-ctl', '--list-devices'] process = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE) out, err = process.communicate() out, err = out.strip(), err.strip() for line in [i.split("\n\t".encode()) for i in out.split("\n\n".encode())]: if self.cam.encode() in line[0]: cam_id_from_dev = re.search(r'(?<=/dev/video).*', line[1].decode('utf-8')) self.cam_id_list_in_dev_video.append(cam_id_from_dev.group(0)) process.kill() return self.cam_id_list_in_dev_video def bind_cam_between_dev_udev(self, cam_id): cmd = ['/bin/udevadm', 'info', '--attribute-walk', f'--name=/dev/video{cam_id}'] process = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE) out, err = process.communicate() out, err = out.strip(), err.strip() kernel_for_udev_rules = re.search(r'(?<=KERNELS==\")[^\"]*', out.decode('utf-8')).group(0) serial = re.search(r'(?<=ATTRS{serial}==\")[^\"]*', out.decode('utf-8')).group(0) self.binding_between_udev_dev = f'{kernel_for_udev_rules} {serial}' process.kill() return self.binding_between_udev_dev Than, I have some Django management commands, that are configurating my system (collecting camera … -
