How To Send Basic Auth Headers To Django From Angular?
I have this in my Angular request service: async login() { var key = localStorage.getItem('access'); var httpOptions = { headers: new HttpHeaders({ 'Content-Type': 'application/json', 'Authorization': 'Basic ' + btoa('username:password') }), }; return this.http.post('https://example.com/login/', httpOptions); } Here is my Django view: from django.views.decorators.csrf import csrf_exempt from django.utils.decorators import method_decorator from rest_framework.decorators import api_view from django.http import JsonResponse from django.contrib.auth import authenticate, login import base64 import basicauth from django.contrib.auth import authenticate @method_decorator(csrf_exempt, name='dispatch') #@api_view(['GET', 'POST']) def login(request, format=None): auth_header = request.META.get('HTTP_AUTHORIZATION', '') token_type, _, credentials = auth_header.partition(' ') toAscii = credentials.encode('ascii') messageBytes = base64.b64decode(toAscii) message = messageBytes.decode('ascii') user = message.split(':')[0] return JsonResponse({"response":user}) When I do a postman request for Basic Auth the response I get back is: { "response": "username:password" } That's exactly what I want. With the Angular request I get: item Object { response: "" } Doing it with Angular, its as if I didn't send anything at all. HttpClient has a funny way about doing things. I couldn't receive query strings in Django without sending 'Content-Type': 'application/x-www-form-urlencoded', in my headers; I am assuming I need to do something unusual here as well. Anyone know how to get this working correctly? -
Trying to associate a function to a specific radio generated on Django to show a modal
im trying to make a modal show up upon a onclick event function on django, but whenever i try to do it, instead of overwriting/assing the function on the radio, they just generate another radio on the side, how i can do that? This is the html on django where the radios it is generated <div class="form-row"> <div class="col-lg-6 col-12 mb-1" style="line-height: 0px;"> <h6 style="margin: 0px;">TONALIDADE</h6><br> </div> {% for choice, valor in situacoes_disponIns|slice:":3" %} <!-- descobrir como colocar parametro dentro da função --> <input type="radio" class="col-lg-2 col-12 mb-1 d-flex justify-content-center align-items-center" value="{{ choice }}" name="sTonalidade" id="id_situacaoIns"> {% if choice is 2 %} <input type="radio" onclick="funcao1();" class="col-lg-2 col-12 mb-1 d-flex justify-content-center align-items-center" value="{{ choice }}" name="sTonalidade" id="id_situacaoIns"> {% endif %} And this is the function where i call the modal to show up on clickevent <script> function funcao1() // { $("#cq-open").appendTo("body").modal("show"); } </script> -
Django custom lookup field raises EmptyResultSet when passed empty set
I have been trying to implement the not_in lookup field, but it generates a different query to ~Q. On querying against a list of ids such as: ids = [1, 2, 3, 4] both my not_in and ~Q yield same queryset although their generated SQL is different. The issue I found with my implementation was that for example querying against an empty list empty_list ~Q(id__in=empty_list) will return all the rows whose ids are not in empty_list, in this case, all rows. But with my implementation, it returns an empty queryset. Code for above implementation for reference from django.db.models.lookups import In as LookupIn @Field.register_lookup class LookupNotIn(LookupIn): """ Acts as opposite to `__in` """ lookup_name = "not_in" def as_sql(self, compiler, connection): lhs, params = self.process_lhs(compiler, connection) rhs, rhs_params = self.process_rhs(compiler, connection) params.extend(rhs_params) return "%s NOT IN %s" % (lhs, rhs), params It generates different SQL to ~Q: In [28]: print(ShopItem.objects.filter(~Q(id__in=deleted_ids)).query) SELECT "shop_shopitem"."id", "shop_shopitem"."bakery_id", "shop_shopitem"."name", "shop_shopitem"."is_deleted", "shop_shopitem"."is_visible", "shop_shopitem"."number", "shop_shopitem"."description", "shop_shopitem"."special_information" FROM "shop_shopitem" WHERE NOT ("shop_shopitem"."id" IN (5c6a4164-252a-4aa5-abc1-62cebbc3119a, 6dcbc509-435e-4ccc-a6fd-6a48c652278f, f647ceac-34dd-4e1a-8fcd-ebb255b7d6f9, a1be4bc9-0a10-447f-8215-94df18c53fe2)) ORDER BY "shop_shopitem"."name" ASC In [29]: print(ShopItem.objects.filter(id__not_in=deleted_ids).query) SELECT "shop_shopitem"."id", "shop_shopitem"."bakery_id", "shop_shopitem"."name", "shop_shopitem"."is_deleted", "shop_shopitem"."is_visible", "shop_shopitem"."number", "shop_shopitem"."description", "shop_shopitem"."special_information" FROM "shop_shopitem" WHERE "shop_shopitem"."id" NOT IN (5c6a4164-252a-4aa5-abc1-62cebbc3119a, 6dcbc509-435e-4ccc-a6fd-6a48c652278f, f647ceac-34dd-4e1a-8fcd-ebb255b7d6f9, a1be4bc9-0a10-447f-8215-94df18c53fe2) ORDER BY "shop_shopitem"."name" ASC My second implementation … -
post_migrate signal - call just once after all migrations
In this (very simplified) example, I need to do one thing (call do_something_after_all_apps_migrated() ) after all the apps have migrated. The problem is that post_migrate signal is called once for every app. I have one app: after_migrations apps.py from django.apps import AppConfig from django.db.models.signals import post_migrate from django.dispatch import receiver class AfterMigrationsConfig(AppConfig): default_auto_field = 'django.db.models.BigAutoField' name = 'after_migrations' def ready(self): @receiver(post_migrate) def _post_migrate(sender,**kwargs): app_name = kwargs['app_config'].name if app_name == 'after_migrations': do_something_after_all_apps_migrated() As you can see this would work but the problem is that it is not guaranteed that my app (after_migrations) is the latest app that is migrated. That means the Database structure is not guaranteed. How can I call do_something_after_all_apps_migrated() after everything migrated? It does not have to be a signal. -
Customizing Django Admin Add User With Blank Password
I'm am creating a Django web app with customised users authentication policy: only the superuser has a password and the users identification is the email field. The users will only login by OAuth protocol so I don't need to store passwords for them. I created a custom user by overriding AbstractBaseUser class. Is there a way to allow Django Admin interface to add/edit users with a blank password field (unusable password)? Thank you. -
How do I close a browser tab after running Python?
I have a web application where I need to open a new tab, run some Python, then close the tab. The reason I'm doing it this way rather than redirecting to the previous page is because the users would like it to retain the search filters. I'm using Firefox to test it, and I'm aware that Javascript won't close the window if it wasn't opened with Javascript; apparently the same is true if I run any Python functions, because the "cancel" button on the same tab works without any problems. Things I have tried: using HttpResponseRedirect to redirect to a new page with a "close" button that runs a Javascript function to close - the function is definitely being called (I can prove this with a window.alert) but the "window.close()" line gets ignored (no errors or anything, it simply does nothing). using HttpResponse to return 'window.close()' in the Python code - again, if I change it to a window.alert, I can prove the script is running, but again, the 'window.close()' is completely ignored. adding a window.close() function to the Submit button - this only works if I run it before the "submit", in which case the tab will close, but … -

How to set the fields in Django based on inputs?

How to make middleware object callable in Django 2.2

How can I find if there is memory leak for my Docker + Django app?
I'm running my Django app with docker compose. There are 4 containers, web, postresql, nginx, cron. The web container in my dev server is using 170MB Ram, mainly running gunicorn / Django / Python / DRF. The web container in my production server is using 600MB Ram. It's definitely growing over time. I've set max requests and max request jitter for gunicorn (gunicorn byob.wsgi:application --workers=4 --threads=4 --max-requests=1000 --max-requests-jitter=30 --worker-class=gthread -b 0.0.0.0:8000) I don't want to restart the container coz it may affect some users. My questions are: how can I find out if there is a memory leak? how can I reduce memory usage? I am thinking to add a task queue to my 2GB ram server. But this issue may use up the memory. -

django: html form submit without jumping into new page or refreshing/reloading
I am new to django and html. below is my first test web page of a simple online calculator. I found a problem that when clicking the "submit" button, it tends to jump to a new web page or a new web tab. this is not what I want. Once the user input the data and click "submit" button, I want the "result" field on the page directly show the result (i.e. partially update only this field) without refresh/jump to the new page. Also I want the user input data kept in the same page after clicking "submit". I saw there might be several different ways to do this work, iframe/AJAX. Since I am new, what is the really simplest way to achieve this goal?

Rabbitmq not showing messages in django

Here is the screenshots and my code. rabbitmq server is runnig rabbitmq admin panel flower panel celery logs Here is my tasks.py: from __future__ import absolute_import, unicode_literals from celery import shared_task from django.core.mail import send_mail from .models import Order @shared_task def order_created(order_id): """Task to send an e-mail notification when order is successfully created.""" order = Order.objects.get(id=order_id) subject = f'Order nr. {order.id}' message = f'Dear {order.first_name},\n\n' \ f' You have successfully placed an order.' \ f'Your order ID is {order.id}' mail_sent = send_mail(subject, message, 'admin@onlineshop.com', [order.email]) return mail_sent celery config file, celery.py: import os from celery import Celery # set the default Django settings module for the 'celery' program. os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'Onlineshop.settings') broker = "amqp://test:test@localhost:5672/" … -
Django view return data
I have a view that returns an HTML response using render. The data returned is specific to a template. If I want to consume that data on another page, should I write another view with the same logic, or is there a way to pass the data from view 1 to view 2 view return render(request, 'pages/project_details.html', {"project": project, urls path('show_project_details/<project_id>', view=show_project_details, name="show_project_details"), I know that a view is just a function, which takes a request and does something with it, but I don't get how I make a request to a view within a template and consume the response within an existing page. Example here: ## filename: views.py from django.shortcuts import render from .models import Team def index(request): list_teams = Team.objects.filter(team_level__exact="U09") context = {'youngest_teams': list_teams} return render(request, '/best/index.html', context) I want to return the data within this context to home.html and index.html. Hope this makes sense?
