Cannot send React POST request to django api error
I am attempting to send a post request containing the name of a genre of music from react to my django api so that this genre can be put into a query param to be searched using the spotify api.

Unit test in PyCharm fails if imported a class
With PyCharm, we are trying to create a unit test file tests/test_poc.py for a proof-of-concept class PocFunctional, and we have added DJANGO_SETTINGS_MODULE=applicationproject.settings into the "Python tests" section of the "Run/Debug Configurations". However, if we uncomment from app.poc import PocFunctional in the below sample source code to import the class under test, the unit test will get a run-time error saying django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.. Although the file runs OK if not imported the PocFunctional class. We are new to the unit test of Python in PyCharm environment, so we highly appreciate any hints and suggestions.

Requests multiplying with each interaction with input
I'm having trouble with requests that multiply undesirably and I haven't found a solution so far. It turns out that, I have a select html that when an option is chosen, it makes a request to the backend and returns the values of the db in the input below the form, so far so good, the query is being executed and returned correctly, however every changing the option of this select without reloading the page, the requests are multiplied, ex: when I select for the first time, the request is made 1 time, when I select again the request is made 2 times in a row, and this escalates, I tested changing the select 9 times sequences and the same request is performed 9 times in sequence with the same parameters, with the same response, as if there were a variable that at each interaction adds 1 and multiplies the request. here a sample of the select changed 3 times [15/Mar/2023 23:46:29] "GET /propriedades/atualiza_propriedade/17/ HTTP/1.1" 200 102 [15/Mar/2023 23:46:32] "GET /propriedades/atualiza_propriedade/20/ HTTP/1.1" 200 108 [15/Mar/2023 23:46:32] "GET /propriedades/atualiza_propriedade/20/ HTTP/1.1" 200 108 [15/Mar/2023 23:46:35] "GET /propriedades/atualiza_propriedade/22/ HTTP/1.1" 200 136 [15/Mar/2023 23:46:35] "GET /propriedades/atualiza_propriedade/22/ HTTP/1.1" 200 136 [15/Mar/2023 23:46:35] "GET /propriedades/atualiza_propriedade/22/ HTTP/1.1" … -

Django signal creates UserProfile from listening to User, but it's empty?
I'm new to Django and trying to create a signal that listens to a custom User model I've built. My intention is that when a new User is created, that a profile for them will also be automatically created. To me it seems that my signal itself works, as when I use the /admin screen I can add a User and it automatically creates their profile. However, when I try to add a new User through the front end of the application, it appears that the signal does indeed detect a new User being created and creates a Profile for them. But when I go into the /admin screen to have a look at it, it's empty. When I say empty, I mean that the Profile record is created, but none of the fields are populated. This is then causing further errors in my app, because I can't use the User to pull up the User's Profile and render it, because it's empty and not connected to a User. What am I doing wrong? My hunch is that something is wrong with my view function. registerUserParticipant and registerUserSupervisor are called when creating a new user in the front end. editAccount … -

NOT NULL constraint failed null=True blank=True

AppConfig.ready() is running before the migrations on manage.py test
I am trying to use Django's AppConfig.ready() method to run some some query on one of the models to retrieve some data. I have the following code: class NewsConfig(AppConfig): name = "apps.news" verbose_name = "News" def ready(self): NewsType = self.models.get("newstype") NewsType.names = NewsType.objects.values_list("name", flat=True) then, on urls.py I'm using them as follow: news_type_names_regex = generate_regex(NewsType.names) router = DefaultRouter() router.register(r'news/' + news_type_names_regex, NewsModelViewSet, basename='news') This works fine when the application runs (using uvicorn or runserver), but when running tests, the AppConfig.ready() gets executed before the migrations are run, which results in the following error: ... django.db.utils.OperationalError: no such table: news_newstype I've read the warning on the docs, but I don't think it is related to this issue. The reason why I'm doing this on the AppConfig.ready() is because it needs to be done somewhere after django.setup() but not in an async request context (as I'm using django channels and running the application ASGI). -
Failed To Fetch Error with Django Application
Working on a Django app and running in to a failed to fetch error intermittently from my JS code. You can see the network responses below - where the error is intermittent from the server (currently on localhost:8000) My django server logs are showing nothing - so 'connection refused' and 'empty response' are confusing. On the JS side I am using fetch(data.getAttribute('action'), { method: data.getAttribute('method'), body: new FormData(data), headers:{ "X-CSRFToken": csrf_token, "X-Requested-With": "XMLHttpRequest"}, }).then(res=>res.json()) .then(function (data) { console.log(data) document.getElementById('create-submit-button').style.border = "2px solid #ebebeb" if(data.status == 'success'){ //happy path will be to add photos on good response console.log('happy path') } else { Swal.fire({ icon: 'error', title: 'there was an issue with your request', text: data.message, }) } }) .catch(error => console.log('Error: ', error)) } My django view is as follows: @login_required(login_url='login') def create(request): if request.method == "POST": if request.META.get('HTTP_X_REQUESTED_WITH') == 'XMLHttpRequest' and request.user.is_authenticated: print(request.POST) form = SpinForm(request.POST) if form.is_valid(): user = request.user spin = Spin() spin.prompt = form.cleaned_data['prompt'] spin.user = user spin.orientation = form.cleaned_data['orientation'] # save spin to get many to many relationship spin.save() spin.themes.add(*form.cleaned_data['themes']) # update users total spins user.current_spins += 1 user.save() # themes = request.POST.getlist('theme') computed_prompt = '' if len(spin.themes.all()) > 0: for theme in spin.themes.all(): computed_prompt += … -
Django router.register gets called for every request
I'm inheriting this project that has a urls.py which imports a set of urlpatterns as such: # myapp.rest router = routers.DefaultRouter(trailing_slash=True) router.register(r'campaigns', CampaignViewSet, 'campaigns') router.register(r'campaign-search', CampaignSearchViewSet, 'campaign-search') router.register(r'guestbook', GuestBookViewSet) router.register(r'updates', UpdateViewSet) router.register(r'albums', AlbumViewSet) urlpatterns = [ url(r'^api/', include(router.urls)), ] Now in another set of urls, i'm adding some new api endpoints: urlpatterns = [ url(r'^rest_1/campaigns/(?P<filter>\w+)$',views.RestCampaignView.as_view()), ] So my main urls.py looks like: from myapp.rest import urlpatterns as rest_urls # router.register calls urlpatterns = patterns( url(r'^v2/api/', include('hhl.apps.rest_1.urls')), ) urlpatterns += rest_urls Now whenever I call my new rest endpoints, v2/api..., I'm seeing that the myapp.rest urlpatters are re-registered, and it's actually calling each viewset before it's even getting to my new view. This is Django 1.8.9 so it's a bit dated. How can I fix this so that it's not calling every Viewset for every request? -
Run a subprocess and show output in realtime AND log stderr
Yo, I am using python to run a subprocess that takes a while to execute, and that may or may not succeed. My question: How can I keep realtime output of the process AND collect error lines? Thanks Here is my code so far: process = subprocess.Popen("my_cmd", shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE) complete_err_message = '' while True: output = process.stdout.readline() error = process.stderr.readline() if output == b'' and error == b'' and process.poll() is not None: if complete_err_message != '': # handle err here print(complete_err_message) break if output: print(output.strip().decode('utf-8')) if error: complete_err_message = complete_err_message + '\n' + error.strip().decode('utf-8') That seems to run very well when the process fails. All the error lines are taken in and stored under complete_err_message. However, when the process doesn't fail, I lose the realtime output and the program seems to lock at the error = process.stderr.readline() step. I am guessing this is because the stderr PIPE is empty, but I am not sure and I don't know how to bypass that. -

How to create two table columns (<td>) in html from one context using Django?
I am using dataTables to show my data, It's just names of some places which i want to put in two columns instead of one. I created two tags in table which allowed me to have two columns but i don't know how to effectively populate it and still have normal pagination. Places even_name odd_name even_name odd_name I tried splitting queryset in two (odd and even) and then used zip() on it. That kinda worked but it wouldn't show last set of items because some lists were uneven. If i tried to iterate over longer list with itertools i would get an error because that one pair has an empty element <table data-page-length='15' id="table" class="display" style="width:100%"> <thead> <div class="col-4"> <tr> <th class="text-end erlorefont col-6" style="color:orange">{{ title.0 }}</th> <th></th> </tr> </div> </thead> {% if lore_list|length > 29 %} <tbody> {% for odd, even in zipped_list %} <tr> <td class="erlorefont "><a style="text-decoration:none;" href="{% url 'lores:loreitems' odd.id %}">{{odd}}</a></td> <td class="erlorefont "><a style="text-decoration:none;" href="{% url 'lores:loreitems' even.id %}">{{even}}</a></td> </tr> {% endfor %} </tbody> {% endif %} </table> I expect something like this in case there is uneven number of elements in a zipped item. I want to have two columns per page with 15 … -

Change Display Values for Cloudinary Field in Django Admin
So in my model I have: cloudinary_logo = CloudinaryField('image', blank=True, null=True) In the admin for this model, I list the field in fields. And it displays as such. I'd like to update the name to be "Logo Location" and the description to say something like "drag image file here to upload!" How would you go about doing this? TIA I'm considering a custom method that would allow me to write the html, but I don't want to screw up the functionality of the Cloudinary Field itself, so I'm not sure if this would be the best way. I've written a custom save_model that looks as such: def save_model( self, request: str, obj: Community, form: forms.ModelForm, change: str ) -> None: #check if cloudinary logo was changed super().save_model(request, obj, form, change) if 'cloudinary_logo' in form.changed_data: #move it, rename it moved_file_name = f"{ENV}/logos/{obj.id}-{obj.external_id}-{obj.name}" cloudinary.uploader.upload(obj.cloudinary_logo.build_url(), public_id=moved_file_name) obj.cloudinary_logo = moved_file_name obj.save() -

Apply an update to a queryset involving a foreign key
Lets say I have something like the code below, where I can nicely apply the update method to change the engine type of the cars contained in the query set vintage_cars. Is it possible to use update in a similar fashion for the code using the for loop, where a foreign key is involved? class Driver(Model): name = CharField() licence = CharField() class Car(Model): driver = models.ForeignKey(Owner) status = CharField() type = CharField() engine = CharField() vintage_cars = Car.objects.filter(type="vintage") vintage_cars.update(engine="gas") for c in vintage_cars: driver = c.driver if driver and driver.licence not in VALID_LICENCES: c.driver = None c.status = "IMPOUNDED" d.save() I'm thinking I need to apply a second filter involving this clause: if driver and driver.licence not in VALID_LICENCES: to vintage_cars, but I'm not sure if that makes sense in terms of efficiency. -

I don't think it is a good behavior and I want people to be "forced" to go through the reverse proxy. How can I do that ? Thanks. -

Django HTML Select not loading correct option
Im having some trouble at my first Django project. I have a ListView in which I have several comboboxes (select) to filter data in a table. Im using Foundation for my site The problem I´m having is that once I establish the "filters" for the queary in my comboboxes, data is presenting fine, but after loading the table, one of the selects is not loading the correct option(last lookup) This is my ListView code: class ListSales(LoginRequiredMixin, ListView): template_name = "sales/list.html" context_object_name = 'sales' login_url = reverse_lazy('users_app:user-login') paginate_by = 5 def get_queryset(self): client = self.request.GET.get("clientselect", "") payment_method = self.request.GET.get("paymentselect", "") date1 = self.request.GET.get("date1", '') date2 = self.request.GET.get("date2", '') product = self.request.GET.get("productselect", '') if date1 == '': date1 = datetime.date.today() if date2 == '': date2 = datetime.date.today() queryset = Sale.objects.get_sales_list( date1, date2, client, payment_method) qty_total_product = 0 if product != '0' and product != '': print(Product.objects.get(id=product).full_name) print(queryset) for querysale in queryset: print(querysale) for query_sale_detail in querysale.sale_details(): print(query_sale_detail.product.full_name + " " + str(query_sale_detail.count)) if str(query_sale_detail.product.id) == product: qty_total_product += query_sale_detail.count print(qty_total_product) obj_sales_list_filter, created_obj_sales_list_filter = SalesListFilters.objects.get_or_create( id=1, defaults={ 'datefrom': date1, 'dateTo': date2, 'client': Client.objects.search_id(client), 'payment_method': PaymentMethod.objects.search_id(payment_method) }) if not created_obj_sales_list_filter: obj_sales_list_filter.datefrom = date1 obj_sales_list_filter.dateTo = date2 obj_sales_list_filter.client = Client.objects.search_id(client) obj_sales_list_filter.payment_method = PaymentMethod.objects.search_id( payment_method) obj_sales_list_filter.save() …
