Postman giving "Invalid pk \"1\" - object does not exist."
I'm making a post request to a django server using Postman. But i'm getting the following error [ { "question": [ "Invalid pk \"1\" - object does not exist." ] } ] The object exists with pk = 1. I don't know why postman adds the " in the request and maybe that what causes this. Can you please tell me how to take off the "\ from it. Here is my request : {"user":1,"form":2,"completed_at":"2018-09-04T00:00:00+0100","device_id":5,"responses":[{"resourcetype":"ShortTextResponse","question":1}]} -

Passing foreign key through url with Django

pull audio file from django backend in vuejs
I am trying to build an app that would transfer recorder audios from the vuejs front end to my django back end and get them back. However I have troubles with both ways: front -> backend : my audios recordings are 'blobs' format. Should I 'send' in vue to django the entire blob and django would store it or would I juste create an url and vue would store the file on the server ? backend -> front : I try to display an audio by putting in the url of where I stored them, however I keep having 404 errors...

How to use function of order_set if I am using filter instead of get?
When I use get instead of filter in views.py, I get error saying customer object isn't iterable, which I understand. But using filter instead of get doesn't allow me to user 'order_set' function (also in views.py), showing up with an error message: 'QuerySet' object has no attribute 'order_set'. How can I workaround this? views.py def customer(request, pk): customer = Customer.objects.filter(id=pk) order = customer.order_set.all() context = {'customer': customer, 'order':order} return render(request, 'accounts/customer.html', context) customer.html <table> <tr> <th>Email</th> <th>Phone</th> </tr> {% for i in customer %} <tr> <th> {{i.email}}</th> <th> {{i.phone}}</th> </tr> {% endfor %} </table> <table class="table table-sm"> <tr> <th>Product</th> <th>Category</th> <th>Date Orderd</th> <th>Status</th> <th>Update</th> <th>Remove</th> </tr> {%for order in order%} <tr> <td>{{order.product}}</td> <td>{{order.product.category}}</td> <!-- the above is chaining --> <td>{{order.date_created}}</td> <td>{{order.status}}</td> <td><a href="">Update</a></td> <td><a href="">Remove</a></td> </tr> {% endfor %} </table> urls.py urlpatterns = [ path('', views.home), path('products/', views.products), path('customer/<str:pk>', views.customer) ] -

Mark all duplications in annotations
I have a model: class Order(models.Model): data = models.TextField() sessionid = models.CharField(max_length=40) I need to get queryset where every unique sessionid will be masked as name or something. For example if I have 3 objects { "data": "...", "session_id": "foo" }, { "data": "...", "session_id": "foo" }, { "data": "...", "session_id": "bar" } query should annotate each unique session_id to return: { "data": "...", "name": "A" }, { "data": "...", "name": "A" }, { "data": "...", "name": "B" } How could I make this query?

Test Concurrent Clients in Django's TestCase
I want to test the performance of Django when a number of clients making requests concurrently. I had no luck using Python's multiprocessing package in a TransactionTestCase case but got it to work using threading, like this: class UserRegisterTestCase(TransactionTestCase): NUM_PROCS = 5 @staticmethod def register(): email = '{}@test.com'.format(threading.get_ident()) c = Client() c.post(reverse('my_login'), {'action': 'register', 'email': email, 'password_1': '12345', 'password_2': '12345'}) connection.close() def test_register(self): threads = [] for i in range(self.NUM_PROCS): threads.append(threading.Thread(target=self.register)) for t in threads: t.start() for t in threads: t.join() self.assertEqual(MyClients.objects.count(), self.NUM_PROCS) The test passed, but I wonder with Python's GIL, is it true that 5 concurrent clients are trying to register at the same time, or is it just some syntactic sugar in that under the hood, Django sees and handles one client request at a time? If latter is the case, what's the right way to test for concurrent clients? Thanks. -

Python unittest and coverage missing not working
I have the following function: def edge_delete_check(id: str) -> bool: queryset = NsRequestRegistry.objects.filter( **{ 'nsr_insd__constituent-isd__contains': [ {'id': id} ] } ) if not queryset: return True else: return False And when I run my tests, coverage tells me that i'm missing on return False. So I've been trying to run a test that tests the False condition on my function above. class HelperTests(unittest.TestCase): """Tests helper functions""" def test_edge_delete_check_false(self): result = edge_delete_check('e932bb55-44cb-4ec4-a0cb-1749fe51e5fd') self.assertTrue(result, False) The given id should return a False for result = edge_delete_check('e932bb55-44cb-4ec4-a0cb-1749fe51e5fd'), which it does, which means the given id can not be deleted as queryset in the function above returned a non-empty result. But doing a self.assertFalse(result, False) throws an AssertionError: True is not false : False. If I change my assert to: self.assertTrue(result, False) the test passes but the coverage report still says that my return False on my function is missing. So the two questions I have are: How should I write my test to test the return false statement on my function above? How can I get coverage to report that it has tested the return false statement and is no longer missing? Thanks for any help. -

Django channels create a separate task that sends message to group at intervals
Essentially I am trying to create a real time applications for teams with Django channels. What happens is that there is a physics simulator that runs on the server and then sends the game state to be displayed on the client machines. What I need is a function that runs every 1/20 seconds on the server and then sends an output to each socket in a group. What I am currently thinking of doing is using threading to spin up a task (only needs to run for 60s total) which runs the physics simulation and then waits for the remaining time until the next execution. But I can guess that there is a real way to do this with Django channels which I can't find in the documentation. -
