how to keep loop runnning while user gets redirected back to form after making a post request to start the loop
I have a django app with a view that handles a post request from a user to start an infinite loop. The problem is after succesful post request loop starts and the browser keeps loading waiting for response from the server resulting to timeouts from proxy server handling this request. Is there anyway to start the loop and keep it running while redirecting or giving back response to the browser to prevent timeouts view code below: def ticket_miner(request): mining_urls = credentials.mining_urls if request.method == 'GET': form = forms.UpdateForm() return render(request, 'tickets/mine.html', {'form': form}) else: net_test = network_acess.network_test(urlpaths.net_urls) while net_test: with requests.session() as s: try: print('logging in ....') s.post(login_url, data=payload, headers=headers, timeout=5) r = s.get(success_url, timeout=5) print(r) if r.status_code == 200: print('Logged in successfully') while r: count = 0 for mining_url in mining_urls: r2 = s.get(mining_url, timeout=5) count += 1 response_result = r2 if response_result.status_code == 404: print('TICKET NOT FOUND!') pass else: new_data = response_result.json() miner.ticket_mapper(new_data) print('mining') continue print('mining successfull restarting ...') else: print('Unable to authenticate... redirect detected') except requests.exceptions.ConnectionError as e: print(f'ConnectionError: {e.response} response.

Django automated email sending
I am building a multivendor market place using django and I have to send automated emails for two reasons. I have to verify their email each time someone signs up (A verification email will automatically be sent when they completed their form). Automated email is sent to the user when order is ordered. All the above worked fine when I test them, but I used my gmail account for that purpose. I have read that gmail is not the perfect choice for business purposes. Plus there is no online payment system in my country for payed services and all the free options I see can only send very limited emails per day. So should I continue using gmail? Or is there any other system I can use? Thank you in advance! -
How can I utilize the JWT for authintication and authorization in Django
I started learning Django two weeks ago, while I was searching for authentication and authorization in Django I found the following lines for Jason Web Tokens (JWT): project urls.py from django.contrib import admin from django.urls import include, path from rest_framework_simplejwt import views as jwt_views urlpatterns = [ path("admin/", admin.site.urls), path("api/v1/cookie-stand/", include("cookie_stands.urls")), path("api-auth/", include("rest_framework.urls")), path( "api/token/", jwt_views.TokenObtainPairView.as_view(), name="token_obtain_pair", ), path( "api/token/refresh", jwt_views.TokenRefreshView.as_view(), name="token_refresh", ), ] app permission.py from rest_framework import permissions class IsOwnerOrReadOnly(permissions.BasePermission): def has_object_permission(self, request, view, obj): if request.method in permissions.SAFE_METHODS: return True if obj.owner is None: return True return obj.owner == request.user My question is: Tokens are usually sent as a header with the request, how does Django do that? I mean for example, how can I use Django and JWT to make an authorized group of users? -
Correct way to define the initial value of a form field in Django from a database, when database values may change
I am trying to create an interview feedback capture app using Django. The interview feedbacks follow a template. The template would evolve with time. Therefore whenever a new interview feedback template is available, it is updated to the database by an admin user. Whenever an interviewer opens the app, he should see the latest value of the template available in the database as the initial value of the feedback form. Currently I am able to provide the initial value of the feedback field using the 'initial' argument of the feedback field. Below is the code: from django import forms from .models import R1 from .model_templates import template_R1 from ckeditor.widgets import CKEditorWidget class R1Form(forms.ModelForm): interview_date = forms.DateField(widget = DateInput()) feedback = forms.CharField(widget = CKEditorWidget(), initial = template_R1.objects.all().last().template) class Meta: model = R1 fields = ['interview_date', 'interviewers', 'comment', 'recommended_level', 'progress'] The problem with this approach if that if the template is updated the form field still shows an earlier snapshot of the template when the django server was started. Is there any other way the form field would show dynamic values as soon as the template is updated in the database? -

Django AssertionError when testing Create View
I'm running some tests for my app 'ads', but when I try to test the CreateView it fails with the following message: AssertionError: 'just a test' != 'New title' Here's the test: class AdTests(TestCase): def setUp(self): self.user = get_user_model().objects.create_user( username='test_user', email='test@email.com', password='secret' ) self.ad = Ad.objects.create( title='just a test', text='Ehy', owner=self.user ) def test_ad_create_view(self): response = self.client.post(reverse('ads:ad_create'), { 'title': 'New title', 'text': 'New text', 'owner': self.user.id, }) self.assertEqual(response.status_code, 302) self.assertEqual(Ad.objects.last().title, 'New title') self.assertEqual(Ad.objects.last().text, 'New text') So it could be that the test fails in creating a new ad, and then it compares the fields with the first ad in the setUp method.

Filter Categories from list of Products in Django templates
So I'm working on this Django e-commerce website where I'm supposed to filter the products on my page based on three separate categories. Since there were only three fixed categories, I decided to create a dictionary in my model class for Products and thought there would be a way to filter products later on in my templates accordingly using a {%For%} loop. It's not working as I expected tho and I'm getting errors, probably because I'm not that familiar with Django and don't know how to get my way around it. Would greatly appreciate the help!

Why can't i display my foreign key instance in Django?

Django Query Annotation Does Not Support math.tan() Calculation
I have a django 3.2/mysql website. One of the tables, Flights, has two columns, angle and baseline. These two columns are combined in a view to display the value altitude using the formula altitude = baseline * tan(angle). I am building a search form for this table, and the user wants to search for flights using a minimum altitude and a maximum altitude. My normal approach to the problem is to gather the inputs from the search form, create appropriate Q statements, and use query the table with filters based on the Q statements. However, since there is no altitude field, I have to annotate the query with the altitude value for the altitude Q statement to work. It seems that a query annotation cannot use an expression like math.tan(field_name). For example, Flights.objects.annotate(altitude_m=ExpressionWrapper(expression=(F('baseline') * math.tan(F("angle"))), output_field = models.FloatField(),),) generates the error builtins.TypeError: must be real number, not F whereas the expression Flights.objects.annotate(altitude_m=ExpressionWrapper(expression=(F('baseline') * F("angle")), output_field = models.FloatField(),),) does not generate an error, but also does not provide the correct value. Is there a way to annotate a query on the Flights table with the altitude value so I can add a filter like Q(altitude__gte= min_altitude) to the query? Or, is … -

How to rank query results when using Q objects in Django
I am building an jobs database using Django. The user should be able to search for an jobs using its title,and its company, etc. I am currently using Q Objects to construct the query: if keyword: q=Q() qs = stemming(keyword) for key in qs: q &= Q(title__iregex = r'\b{}.*\b'.format(key))|Q(company__iregex=r'\b{}.*\b'.format(key)) jobs_list = jobs_list.filter(q).distinct() jobs_count = jobs_list.count() jobs_list = jobs_list.order_by('-title') I would like to order the results by relevance. As far as I understand this is usually accomplished by using annotate(): A ranking number is set and then used by order_by(). However, I am not sure how to do this when using Q objects. Is it possible to "annotate" Q objects? Or am I barking up the wrong tree here? Maybe someone can help, Thank you.. -

View and CSS are not updated on mobile after I modify an element classlist with javascript
So for some context, I have a portfolio page with some projects which I can filter by tags. The CSS (color) of the tags change when it's selected/deselected, by adding/removing a selected class to the element. But somehow a selected tag doesn't go back to it's initial state when it's clicked a second time, even though the class list is correctly updated. This happens only on mobile (I could test on Android and iOS), the behavior is the one expected on desktop.

how to send every specific time interval in django websocket?
When a user requests a post, the sever sends the progress of the work to the websocket When the process is finished, send a message that it is finished. Then javascript receives the message and requests to get to a specific url. The server does the filer response. The question here is how the actual service checks progress asynchronously... First of all, the code is as below. class GifConsumer(WebsocketConsumer): .... def receive(self, text_data): ... t = downloand_video.delay(data) # celery while not t.ready(): # async_to_sync(asyncio.sleep)(1) self.send(text_data=json.dumps({ 'message': "Doing" })) self.send(text_data=json.dumps({ 'message': "Done" })) The code keeps checking the status with while statements, so it seems to waste resources too much. How can I modify this? If use sleep, the web server will sleep. so, I don't think I can even request get, post.
