button 'pay now!' not working for redirect to payment-done view in payment-braintree and django
I am writing an online store based on the Django 3 By Example 3rd Edition book. I encountered a problem with the book's codes in the payment section, I searched the internet and updated some of the codes, but I still have a problem! After filling out the debit card form, when I click on the "pay now!" button, I am not redirected to the Don page!

Update user profile with user uuid
I want to update user profile passing user uuid as kwarg. Here is the url: path("profile/update/<uuid:pk>", UpdateProfile.as_view(), name="update_profile"), However, after I try to update my profile, it gives me an error. Here is my view: class UpdateProfile(LoginRequiredMixin, UpdateView): model = Profile user_type_fields = { "Buyer": ["photo", "first_name", "last_name", "city"], "Celler": ["photo", "name", "city", "address"], } def get(self, request, *args, **kwargs): print(kwargs) self.fields = self.user_type_fields[get_user_model().objects.get(pk=kwargs["pk"]).type] return super().get(request, *args, **kwargs) And here is the error itself: Page not found (404) No profile found matching the query As I understand, django tries to find profile with uuid as in url, doesn't find it and returns me this error. However, if I change model in my view to user, it wouldn't be able to find fields as they belong to profile model. The only working option was to pass profile id as kwarg, but I don`t find it preferrable due to security reasons. Could someone give me an advice on how to update profile with user uuid in kwargs? Thanks in advance! -
Authenticate serverless API against Django user pool
I would like to move an API from Django server on ec2 to serverless (AWS API gateway + Lambda) because of better scalability. I need authentication/authorization for this API against my Django user pool, but that would mean polling Django server because of auth.. and I am back where I was regarding scalability. What would be my option to deal with it in a scalable (lambda like scalable) way? I was thinking about creating Cognito user pool and duplicate users from Django there. Is there a better option? -

Point of Sales System Using python
Point of Sales System Using python. Guys, I need your experience to develop my POS system. These are my question. Please share your opinion about this question. This is my basic idea about this POS system. I am trying to create a POS system for a shop with various items such as supermarkets and electronic items. It means that has multiple types of products in this shop. I need to add stock management also this software not only that it is necessary to add expiration dates to some categories of products as well (My idea is to send an alert to shop owners about expired that products). Among these features, I need to add a thermal printer and a barcode reader as well. And also I need to generate some sales reports as well with the net profit. These are my questions. I decided to use python to create my POS system. Is that language ok for that software? If it is ok, If I try to implement it as a stand-alone application, which is the most suitable GUI builder for that? (Ex: PyQt, Tkinter, Kivy). Is that ok to use Django for this ? Based on my basic idea … -
How to safely add an additional fee for additional services in an online store?
I have an online car rental store built on Python Flask. My problem is that: When choosing a car, the customer goes to the checkout page, where he can choose additional services, for example: GPS navigator, child seats and other services. The cost of some services depends on the number of rental days, for example, for a Gps navigator, the cost of 1 day is $ 5. The question is, how can I safely get the cost of these additional services from the FrontEnd and add to the cost of the car received from the BackEnd side I am trying to safely connect the cost of renting a car with the cost of additional services, some of which depend on the number of rental days.My task is to implement this system as safely as possible, but I do not know how it can be done -

django rest framework what is login as the definition
Let me say in advance that thank you for reading my question. The problem I'm facing is related to login and permission from frontend. For example, log in as a user from the browser(like hit localhost:8080/admin in the search engine), and then you can see the user name on the right upper side of the screen which indicates the user is logged in. How Django identify the user login is that when you log in csrftoken is created and set in the cookies, so if you delete csrftoken, the username is disappeared, so you need to log in to access admin if you need. This login system is related to permission.IsAutenticated, so if 'DEFAULT_PERMISSION_CLASSES' : ['rest_framework.permissions.IsAuthenticated'], you cannot access any data if you are not logged in. Then I implemented social google login which receives google access_token to log in as a Django user(I will omit to describe how to get a google access token process), which works fine in the browser. I can see the username on the screen, and permission is working ok. But when I hit google social login endpoint from the front end, I can't log in, also csrftoken is not created in the cookies.(no error … -
PERFORMANCE Calling multiple times a posgres db to get filtered queries vs querying all objects and filtering in my django view
I'm working in a Django project and it has a postgreSQL db. I'm calling multiple times the model to filter the results: latest = Product.objects.all().order_by('-update_date')[:4] best_rate = Product.objects.all().order_by('rating')[:2] expensive = Product.objects.all().order_by('-price)[:3] But I wonder if it's better for performance and resources consumption to just do 1 query and get all the objects from the database and do the filtering inside my Django view. all = Product.objects.all() # Do some filtering here iterating over variable all Which of these do you think would be the best approximation? Or do you have a better option? -
