Django extra button in a model's changelist for Django Admin
So I want to add an extra button in my Fun model's changelist_view which when pressed, performs a function and redirects me to a new page. I don't want to have this function for every app nor do I want for every model, only the Fun model. And I will be using Django Admin to view this changelist, just a side note. Can anyone suggest anything? Thanks. -
Django REST Framework API: Unable to Get String Value of a Field
I am a beginner in Django. Right now, I am working with the APIs. I am facing a problem. I can't view the string value one of the fields, called label, at http://127.0.0.1:8000/gameapi/.

Django sending data to another server to start scraping with python
So I have this problem which I can't figure out how to go about it. I would be glad if someone can give me the best approach to solving the problem before I start writing the code. As they say, "First Solve The Problem Then Write The Code". Here is the problem. I want to have my django app in serverA e.g example.com - So registered users can post or start a scraping task. For example a user would fill a city form by entering say New York and on save or clicking start task, the data is sent to domain.com/user_base64_string/?property=New%20York which is a different server. domain.com accepts this request and trigger the python scraping script. On doing so the User would not be able to start another scraping task if he has 2 or 3 unfinished tasks running. During the scraping, domain.com sends status data using a get request to the example.com which get stored in database so user can running task, number of properties found. And of course see when task is completed. domain.com been server2 or scraping server stores the files locally and when would send it back to the user in example.com on request so it … -

Django - approach to code repetition in Unit tests
Short introduction. I'm just learning to write tests for my application. The application is an online gradebook. Below is the code from the homepage view test. Only the login form is there. If the user logs in for the first time, he is redirected to the view that forces to change the default password. If this is the next login, it is redirected to the right view, depending on the user rights. Problem. In this test of the view, I had to create 6 users and related models (Student, Parent, Teacher), so I wrote the methods to create these objects (create_user / create_person). In many future view tests, I will also have to log in users and use models (Student, Parent, Teacher). How should I repeat these steps? Two ways come to mind. 1. Convert methods to static and use them in the next test classes to create objects. Will the tests still be "unitary"? 2. Copy the method definitions to each next test class in which they will be needed. Will this not break the DRY principle? Which approach is good? class HomepageViewTestCase(TestCase): password = 'testerspass' def create_user(self): username = 'tester' numbering = 0 while True: try: User.objects.get(username=username) numbering … -
Securing Typeform Webhook Python
I'm trying to accept form responses from Typeform using Python/Django/DRF and am having trouble authenticating the webhook request due to not being able to get the hashes to match. Here are the instructions from Typeform: 1. Using the HMAC SHA-256 algorithm, create a hash (using created_token as a key) of the entire received payload as binary. 2. Encode the binary hash in base64 format. 3. Add prefix sha256= to the binary hash. 4.

How to restrict unauthorized user to have access to different pages in django
I have this model: class Student(Model): user = OneToOneField(CustomUser, on_delete=CASCADE, related_name='student', ) and this url: path('students/<int:student_pk>/', student, name='student') and this view: @login_required def student(request, student_pk): return HttpResponse('This is your personal panel') Well, by using login_required decoration I am restricting users that are not logged in to see student panel page. However, other students who are logged in can see other's panels. How can I restrict them from this? I can do this: @login_required def student(request, student_pk): student_ins = get_object_or_404(Student, pk=student_pk) if student_ins = request.user.student: return HttpResponse('This is your personal panel') else: return HttpResponse('Please do not try to see other students' panels! You are not authorized to do this') However, I prefer to do it in decorator. For example log out the logged in student with primary key pk=1 if he/she entered this in the url: www.example.com/students/2 -
