Django - Sending POST request to another webiste - lack of headers
I'm currently struggling to integrate third-party payment system with my django website. When sending POST request along with form data to payment site it responds with an 403 Forbidden error - CSRF verification failed. You are seeing this message because this HTTPS site requires a 'Referer header' to be sent by your Web browser, but none was sent.. I've installed cors_headers, configured it as suggested in documentation and set CORS_ALLOW_ALL_ORIGINS temporarily to True. When inspecting network tab I've noticed that when requests are within same domain requests are included: same-origin-headers But when sending POST request to the third-party site, they are not: cross-origin-headers I'm including my django view as well as html form: Django view: def payment_loading(request): if request.method == 'GET': order = Order.objects.get(session=request.session.session_key) context = { 'order': order, } return render(request, 'payment_loading.html', context) HTML form: <h1>Processing payment</h1> <form name="dotpay_post" action="https://ssl.dotpay.pl/test_seller/" method="POST"> {% csrf_token %} <input name="api_version" value="{{ order.dotpay_object.api_version }}" type="hidden"> <input name="id" value="{{ order.dotpay_object.shop_id }}" type="hidden"> <input name="amount" value="{{ order.dotpay_object.amount }}" type="hidden"> <input name="currency" value="{{ order.dotpay_object.currency }}" type="hidden"> <input name="description" value="{{ order.dotpay_object.description }}" type="hidden"> <input name="control" value="{{ order.dotpay_object.control }}" type="hidden"> <input name="url" value="{{ order.dotpay_object.url }}" type="hidden"> <input name="type" value="{{ order.dotpay_object.type }}" type="hidden"> <input name="urlc" value="{{ order.dotpay_object.urlc }}" type="hidden"> <input … -

django complete email verification
before this question is going to be marked as a possible duplicate, I want to address a few things. I want to make sure that users have a single email field called email. They also have an is_verified field to indicate whether the email has been verified. There are a few pitfalls in most of the email verification implementations. Lets say that an user creates an account and has an unverified email. Lets say that the user does not actually own the email, though. Now, the actual owner of the email enters the site. But, as the email is already saved in the database, we get an integrity error - that the email is already in use. Thus, any scammer can enter a random email and claim it. This reduces the user experience. How can this be avoided so as to provide a complete email verification system? ( One where the actual owners can claim their emails) thanks a lot! -

Django: Is there a way to manually order objects in a ManyToManyField?

How to automatically update a page without refreshing in django?
I am creating a website using Django on the stock market. I am fetching the live stock market data from an API. I want to update the live price of a stock every 5 seconds (which is given by the API). How can I do this without refreshing the page? I found that Ajax is very helpful for this but I am not being able to implement this properly. Thus, can someone please give an example of the code which is required in the html page to update the values using Ajax. I was thinking of using a separate URL which could send the data in a JSON format. Please help me out if possible. -

How to store and authenticate different user types in Django?
There are two different types of users, A & B. Users of type A authenticate using username and password while type B have email and password. The project uses token based authentication. The question is: how to manage both user types simultaneously? The approaches I have considered: Separate models for both user types and implement a custom auth backend to authenticate user signing in using email Single user model to cater for both user types. However, this would mean I have to an add additional field (email) and populate some random value for users of type A Apart from this, I have to store some custom information for logged in users like device type, location etc. Is it possible to override authtoken_token table to store this info or I have to create a separate model for that?
