POST form data and wait the response or any other possible solution?
I made the research but couldn't found the answer I am looking for, most likely due to my failure to address the question properly. I hope I can do better here. So, I have a web form and I am sending this form's fields as JSON to the backend server via a POST request. The server should send back a JSON response to the client after a computation according to those fields. This computation could take up to 5 minutes or so on. My question is, does the server should send back the computed JSON as the response to this POST request? Or, is there any way to do something like set the job with a POST request, then GET the result somehow? Or, is there any other ways, like, what is the best practice? If the description is too vague, I can give more implementation detail. -
Create,Update in different view and get in different view in django class based view
My urls.py def generate_urls(): for service in SERVICES_MAPPING: service_name = service.split('_')[0] if 'list' in service: yield path( "v1/{}/".format(service_name), GenericListView.as_view(), name=service ) if 'detail' in service: yield path( "v1/{}/<int:pk>/".format(service_name), GenericDetailView.as_view(), name=service ) My view.py class GenericListView(APIView): def get(self, request, format=None): #for list view class GenericDetailView(APIView): def get(self, request, pk, format=None): #for detail view Urls.py is creating many urls and sending to same view for list and detail view.But for Create and Update i want to create seperate view with same url. In more detail: This are few urls created by urls.py.There are many. api/ v1/browser/ [name='browser_list'] api/ v1/browser/<int:pk>/ [name='browser_detail'] api/ v1/language/ [name='language_list'] api/ v1/language/<int:pk>/ [name='language_detail'] Now for 'v1/browser/' and 'v1/language/' calls GenericListView.'v1/browser/int:pk/' and 'v1/language/int:pk/' calls GenericDetailView.But when i create,update in 'v1/browser/' i need seperate view for this with same url. -
from_db_value error with cache in django3.0.10
I'm trying to update to Django3 and got an error in cache. Is it an existing bug because it's all an error in the Django package? It seems that this error occurs when the query is cached and the content of the query is empty. How can I handle this error?

how to deploy django/react app to heroku with different directory structure
I have a django/react app I created using this tutorial here Although slightly different, I then tried to deploy my app to heroku using this tutorial here The directory structure following the tutorials are different though. My directory structure is as follows... django-todo-react/ backend/ backend/ todo/ manage.py ... frontend/ all my react stuff... in my django-todo-react folder (the project root directory) I have requirements.txt, Procfile, package.json, and '.gitignore` file. To my understanding the Procfile should contain something like web: gunicorn backend.wsgi but because my Procfile is in the root directory I do instead the following web: gunicorn backend/backend.wsgi that looks very weird but basically I go into my backend folder where I have my actual backend project I started with django-admin startproject backend and get wsgi. I added all the other stuff from the second tutorial I mentioned this one but still no such luck. I get a COLLECT_STATIC error and if I silence the error everything passes but I then get a application error when opening my heroku app. I have already tried deploying an app just using the 2nd tutorial and all worked fine but that had the directory structure of the second tutorial. I thought that changing … -
Clarification of Django and Celery workings
I implemented an installable app of Django which includes a Rate Limiter (a Python object), but I am afraid of going to production because I find no documentation or readings regarding how production server works compared to Django dev server. The Rate Limiter is a Python object, all the request should go through this limiter in order to be "safe" to make calls (to an API). So far in the Django dev server it is working as expected (everything shares the same rate limiter), but when I enable logs, I see that the app (and the limiter) was initialized twice, which wasn't clear of what is happening at all. While it does work on the dev server, I find no docs of production servers (the server I am using is Daphne or Apache depending if I add websockets support) if this still works as expected (they share the same object). Another question I have is regarding Celery, will Celery tasks also share the same app object (and rate limiter)? I have a task that runs periodically for a large amount of time. -
Django filter returns queryset with ID instead of username
Hi guys so I have a search function but when using the .objects.filter() method I get a queryset that shows an ID instead of the username. This is the view: def search_expense(request): if request.method == 'POST': search_str = json.loads(request.body).get('searchText') expenses = Expense.objects.filter( amount__istartswith=search_str) | Expense.objects.filter( date__icontains=search_str) | Expense.objects.filter( description__icontains=search_str) | Expense.objects.filter( category__icontains=search_str) data = expenses.values() return JsonResponse(list(data), safe=False) <QuerySet [{'id': 16, 'amount': 2.33, 'date': datetime.date(2020, 10, 2), 'description': 'Something', 'owner_id': 1, 'category': 'Food'}]> So instead of the 'owner_id': 1 I need it to be 'owner': username The model (the User model is Django's standard model): class Expense(models.Model): amount = models.FloatField() date = models.DateField(default=now) description = models.TextField() owner = models.ForeignKey(to=User, on_delete=models.CASCADE) category = models.CharField(max_length=255) def __str__(self): return self.category class Meta: ordering: ['-date'] -
Media Files not Loading on pythonanywhere.com (Django)
I deployed a personal portfolio project using pythonanywhere.com's server and my instructor sent me a video explaining why my media files weren't loading properly (https://d.pr/v/RARFcF) but I couldn't understand what he was telling me I should do about it. If you look at my urls.py file I believe my code is good. Can someone please examine this, thanks? Can someone please watch it and help me understand what he was trying to tell me to do!?

Graphene-django - Mutating types with enums
So, I have the following model: class Semester(models.Model): course = models.ManyToManyField(Course, through='CourseSemester') class SemesterType(models.TextChoices): A = 'A', 'Winter' B = 'B', 'Spring' SUMMER = 'SU', 'Summer' name = models.CharField( max_length=200, choices=SemesterType.choices, default=SemesterType.A, ) year = models.IntegerField() I try to add a mutation to add a new semester. Graphene-django seems to automatically generate an Enum field for me, but how can I get it inside the arguments? According to the github issues, something like SemesterType._meta.fields['name'] should work, but I can't get it right, even with wrapping it inside graphene.Argument. It is possible to tell Graphene not to convert it to Enum, however I'd rather avoid that if possible. Any clue how to get that right? -

Extract hours & seconds from Django Interval
I have the following Django PostgreSQL query that calculates an interval; querySet = dbname.objects.all().annotate(duration=Func(F('date_start'), F('date_end'), function='age')) which gives me a date interval, evaluated as a timedelta when .values() is called. Now I'd like to further annotate the query to extract the hours & seconds. Tried django.db.models.functions.Extract, django.db.models.functions.Cast, but can't seem to find a solution. querySet.annotate(hours=Extract('duration', 'hour')) ProgrammingError: function pg_catalog.timezone(unknown, interval) does not exist querySet.annotate(seconds=Cast('duration', DateTimeField())) ProgrammingError: cannot cast type interval to timestamp with time zone -
Phoenix (Elixir) Error running test suite
I have inherited a web project with a backend written in Elixir using the Phoenix framework. I am a Python (Django) developer by trade and new to Elixir. There is 0 test coverage on this project, so I thought that would be a good place to start and get familiar with Elixir and Phoenix. But I get an error message running mix test before I can even get started. 16:27:35.818 [info] Application tzdata started at :nonode@nohost ** (Mix) Could not start application cowboy: exited in: :application.cowboy({:description, 'Small, fast, modular HTTP server.'}, {:vsn, '1.1.2'}, {:id, 'git'}, {:modules, [:cow_uri, :cowboy, :cowboy_app, :cowboy_bstr, :cowboy_clock, :cowboy_handler, :cowboy_http, :cowboy_http_handler, :cowboy_loop_handler, :cowboy_middleware, :cowboy_protocol, :cowboy_req, :cowboy_rest, :cowboy_router, :cowboy_spdy, :cowboy_static, :cowboy_sub_protocol, :cowboy_sup, :cowboy_websocket, :cowboy_websocket_handler]}, {:registered, [:cowboy_clock, :cowboy_sup]}, {:applications, [:kernel, :stdlib, :ranch, :cowlib, :crypto]}, {:mod, {:cowboy_app, []}}, {:env, []}) ** (EXIT) :already_loaded And this is where, I am hoping, my ignorance of Elixir and Phoenix is hindering my debugging capability. Is this tzdata that is throwing this error and not letting the test suite load properly? Any direction or insight is appreciated. -
What happens after Django clean method but before commit?
I am using an awesome library called Django Auditlog. It tracks what changes occurred to an object. For model Book if I changed the Author name from 'John' to 'Mary' it records the before value (John), after value (Mary), when it occurred, and what user made the change. It's working except that it is detecting changes that aren't changes for some of my decimal fields. It thinks a change occurs anytime I save this model: it thinks that I started with .00 and changed it to .0. But .00 is the existing value and I didn't change anything. I just saved() the record. I checked the output of the form itself in the clean() method: services_sub_total 44.00 sum_payments 33.00 And then in the database: I just can't figure out where/why this is detecting only one zero in the decimal place - I'm not seeing that .0 anywhere. So I'm wondering what is happening between the clean() method and the commit that might be truncating the .00 to .0 where Auditlog might be incorrectly detecting a change? -
How to correct CORS errors when redirecting to client from server
I have a django server and react client. My app has been making calls, unabated, to the server for various data I have stored to redux state. Furthermore, I have an authorization flow with an external API achieved via a link (not fetch request) to my backend and then, after obtaining the token, redirects back to my front end. All no problem. The issue comes when I try to refresh my token via get request to my backend. That all works, but then when my backend tries to redirect to my front end I get a CORS error: Access to XMLHttpRequest at 'http://localhost:3000/users/1/.../' (redirected from 'http://localhost:8000/api/callback?refresh_token=....') from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. How do I deal with this? Again, note that the redirect works just fine when I initially authorize the user via the external API, it's almost the exact same flow. That's why I am confused about this error. -

ForeignKey child objects disappeared from table

When I run migrate on this, I get: File "manage.py", line 21, in <module> main() File "manage.py", line 17, in main execute_from_command_line(sys.argv) File "/Users/myname/.local/share/virtualenvs/mobiusAPI-NVQT3lgx/lib/python3.8/site-packages/django/core/management/__init__.py", line 401, in execute_from_command_line utility.execute() File "/Users/myname/.local/share/virtualenvs/mobiusAPI-NVQT3lgx/lib/python3.8/site-packages/django/core/management/__init__.py", line 395, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/Users/myname/.local/share/virtualenvs/mobiusAPI-NVQT3lgx/lib/python3.8/site-packages/django/core/management/base.py", line 330, in run_from_argv self.execute(*args, **cmd_options) File "/Users/myname/.local/share/virtualenvs/mobiusAPI-NVQT3lgx/lib/python3.8/site-packages/django/core/management/base.py", line 371, in execute output = self.handle(*args, **options) File "/Users/myname/.local/share/virtualenvs/mobiusAPI-NVQT3lgx/lib/python3.8/site-packages/django/core/management/base.py", line 85, in wrapped res = handle_func(*args, **kwargs) File "/Users/myname/.local/share/virtualenvs/mobiusAPI-NVQT3lgx/lib/python3.8/site-packages/django/core/management/commands/migrate.py", line 243, in handle post_migrate_state = executor.migrate( File "/Users/myname/.local/share/virtualenvs/mobiusAPI-NVQT3lgx/lib/python3.8/site-packages/django/db/migrations/executor.py", line 117, in migrate state = self._migrate_all_forwards(state, plan, … -
Django model manager isn't working as expected
I have a model "Name" in models.py file of a django app. from .managers.py import NameManager class Name(models.Model): ....................... objects = NameManager() I have created NameManager in managers.py file. class NameManager(models.Manager): def get_func(self, arg): .............. def check_func(self, arg1, arg2): .............. Now in my views.py file, when I write: from .models import Name if Name.check_func(arg1, arg2): ......................... I am getting an error: type object 'Name' has no attribute 'check_func' Where am I making mistake? -
Access request.GET or inject a variable in Django's auth login/registration form
I have a custom form using Django's auth library and I want some users to click on a link to login/register that will pre-populate the email field, without them having to enter their email (avoid entering it manually and make sure the user uses the email we have on file). A link like this: /account/login?email=name@domain.com However on the receiving page, I can't use this as Django doesn't permit in templates: <input type="text" name="username" placeholder="Email" class="form-control" required="" value="{{ request.GET.get('email', '') }}"> If there is a way to inject a variable in Django's auth template, I don't know how since the view is not accessible. Is there a way to access request.GET.get() in the templates, or is there a better way to do this? -
What do they mean when they are saying for you to put Authorization (eg. token) in header of each request?
I am using Django and doing calls for API. I have not used headers for Django before. Am I creating a header variable? E.G Let's say my API key is 'abcd', and ID is '123', from what I have in mind I do header = {'API':'abcd', 'ID':'123'} class CancelApt(APIVIEW): def post(request, id): pass Is this what they meant? Can someone give me an example? Thanks.
