Django logging maxbytes
I am using the following snippet in django settings.py for logging. As you can see, currently there is a maxbytes variable under handlers. Is it possible to keep no limit at all for the log file ? If i remove maxbytes line, will django automatically set no limit for log file? because size of log will increase at a huge rate for my app on a daily basis. LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'simple': { 'format': '[%(asctime)s] %(levelname)s|%(name)s|%(message)s', 'datefmt': '%Y-%m-%d %H:%M:%S', }, }, 'handlers': { 'applogfile': { 'level': 'DEBUG', 'class': 'logging.handlers.RotatingFileHandler', 'filename': '/home/sai_avinash/Documents/refactor/unityapp/unity/media/myproject.log', 'maxBytes': 1024*1024*15, # 15MB 'backupCount': 10, 'formatter': 'simple', }, 'console': { 'level': 'DEBUG', 'class': 'logging.StreamHandler', 'formatter': 'simple' } }, 'loggers': { djanngo': { 'handlers': ['applogfile', 'console'], 'level': os.getenv('DJANGO_LOG_LEVEL', 'INFO'), } } } -
"Error during WebSocket handshake" when hosted on Heroku
I'm making a chat server on Django and atm trying to implement websockets. It works fine locally but whenever I launch it on Heroku, websocket is unreachable. Here's my client script: var loc = window.location var ws_start = 'ws://' if (loc.protocol == 'https:'){ ws_start = 'wss://' } var endpoint = ws_start + loc.host + loc.pathname var socket = new WebSocket(endpoint) Full error code: WebSocket connection to 'wss://my-app.herokuapp.com/chat' failed: Error during WebSocket handshake: Unexpected response code: 500 I've seen a variety of similar questions already, and they are either left unanswered or delve into dealing with SSL certificate. There's one answer that would potentially save me (and other folks) alot of frustration if anyone was to confirm it's true. It's quite old and there's no feedback after it was posted: https://stackoverflow.com/a/45173822/7446564. I will gladly provide any of my code if necessary but the real problem (based on other SO questions) is understanding the source of this error. Is this an error in my code, some SSL-shenanigans or simply a matter of switching to paid dynos? -

Django, Bootstrap toast appears whenever I refresh the page instead of when needed
I want to make a toast appear only when a file has been processed. Currently I check from the model.py whether another file exists or not. If it does, the file has been processed. Else not if not. def status(self): if os.path.exists(...)): return "processed" else: return "unprocessed" I'm not sure if it's right to check from model.py. As for my HTML file, I have set the following. {% for td in user.userlist.all %} {% if td.status == 'processed' %} <div class="toast" drole="alert" data-autohide="false" ... > <div class="toast-header"> <strong class="mr-auto">{{ td.status }}</strong> <small class="text-muted">just now</small> <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div class="toast-body"> The file was {{ td.status }} </div> </div> {% endif %} {% endfor %} This works fine whenever it detects the word 'process', but the toast appears everytime I refresh since it detects 'process' repeatedly. I want the toast appear only once when the file has actually processed instead of looking for the word 'process'. Any suggestions are highly appreciated. -
Get list value by comparing values

Django allauth url fetch from react calls signup view form. How can I just send the data to the API endpoint?
I am using React as a standalone SPA connecting to a Django backend with allauth to manage authentication. If I type in the allauth UR on my local browser (192.168.86.28:8000/accounts/signup/ or 127.0.0.1:8000/accounts/signup/), it brings me to a form I can populate with my custom fields. I can enter in the information and it completes the signup correctly in my database. The form looks ugly, however, so I would like to implement my own frontend form using react. A fetch call with the data should simply post it to the database, but instead the fetch call to that URL brings up the form! How can I change this so the URL will instead send the data to my database? mysite/urls.py from django.contrib import admin from django.urls import path from django.urls import include from django.conf.urls import url from allauth.account.views import confirm_email from allauth.account.views import SignupView urlpatterns = [ path('', include('pages.urls')), path('admin/', admin.site.urls), path('accounts/signup/', SignupView.as_view(), name="account_signup"), path('accounts/', include('allauth.urls')), url(r'^rest-auth/', include('rest_auth.urls')), url(r'^rest-auth/registration/', include('rest_auth.registration.urls')), ] mysite/settings.py # rest_framework authentications and permissions REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': [ 'rest_framework.permissions.AllowAny', ], 'DEFAULT_AUTHENTICATION_CLASSS': [ 'rest_framework.authentication.TokenAuthentication' ] } # cors CORS_ORIGIN_WHITELIST = ( 'http://localhost:3000', 'http://192.168.86.28:3000', 'http://192.168.86.33:3000', ) CORS_ALLOW_CREDENTIALS = True ALLOWED_HOSTS = [ 'localhost', '127.0.0.1', '[::1]', "192.168.86.33", "192.168.86.28", ] # … -
Page not found 404 - Django
I'm a newbie to Django and I know this probably has been asked alot of times. So basically what's happening is when I try to create a new project and whenever I'm trying to run my server, by default it's opening http://127.0.0.1:8000/catalog/ and not http://127.0.0.1:8000/. Even if I run the server with my other projects, I'm facing the same error. I followed this django basics tutorial on https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django/skeleton_website Idk but somehow I think it's default address is set to http://127.0.0.1:8000/catalog/. Is there any way I can change it? Regards -
Django NoReverseMatch when using django NamespaceVersioning
I'm trying to implement versioning in django. My project urls.py looks like: from backend.st_site import urls as site_urls router = routers.DefaultRouter() urlpatterns = [ url(r"^v1/sites/", include((site_urls, "sites"), namespace="v1")), url(r"^v2/sites/", include((site_urls, "sites"), namespace="v2")), ] In st_site/urls I got following url: site_list = SiteView.as_view({"get": "list", "post": "post"}) url(r"^$", site_list, name="site-list"), in my settings/base.py I added: REST_FRAMEWORK = { "DEFAULT_VERSIONING_CLASS": "rest_framework.versioning.NamespaceVersioning", "DEFAULT_VERSION": "v1", } This works for the default version (v1). If I run a test class, it works. But when I try to test a v2 version test like: def test_get_all_sites_admin_version_2(self): self.client.force_login(self.admin_user) url = reverse("v2:admin-site-list") response = self.client.get(url) self.assertEqual(response.status_code, status.HTTP_200_OK) I got following error: django.urls.exceptions.NoReverseMatch: Reverse for 'admin-site-list' not found. 'admin-site-list' is not a valid view function or pattern name. Do I need to configure something else? This for example does work: self.client.force_login(self.admin_user) url = reverse("admin-site-list") response = self.client.get(url) self.assertEqual(response.status_code, status.HTTP_200_OK) -

Strange behaviour while using Field lookup in Django
I noticed a strange behavior in in Field lookup while trying up challenge yourself section of MDN Django Tutorial. I wanted to modify view.py to generate counts for genres and books that contain a particular word (case insensitive), and pass the results to context. I tried to achieve this by following code: # Filtering the word 'comedy' from 'genre' attribute(ManytoManyField) present in 'Book' class num_word_in_geners = Book.objects.filter(genre__in='comdey').count() Surprisingly, this throws a ValueError invalid literal for int() with base 10: 'c' So, I did a workaround by replacing 'comedy' with inner_qs: inner_qs = Genre.objects.filter(name__icontains='comedy') num_word_in_geners = Book.objects.filter(genre__in=inner_qs).count() Now more surprisingly, this works! But why? I suspect there is something I don't understand behind these words in Django docs: In a given iterable; often a list, tuple, or queryset. It’s not a common use case, but strings (being iterables) are accepted. Help me clear this query. -

Django Apache2 error - Truncated or oversized response headers received from daemon process [raspberry pi]
I have a django app I have created that runs fine with manage.py runserver and it was working fine before I started working with opencv and imported numpy. I can still use runserver, but I can no longer use localhost in the browser. When I look at the log (/var/log/apache2/error.log), I see the following error: Truncated or oversized response headers received from daemon process 'myproject' : [path_to_my_project]/wsgi.py. When I type in localhost into the browser I get the following: I have searched for answers but they haven't helped: I've tried added WSGIApplicationGroup ${GLOBAL} to /etc/apache2/sites-available/000-default.conf NOTE: I placed it below the WSGIAlias line but not within the <Directory></Directory> tags. 2. I've tried adjusting the timeout in /etc/apache2/apache2.conf (I believe the default was 400) 3. I've seen a lot of suggestions say it's because of numpy and similar python C extension modules, and some suggest alternates that include a binary. However I don't see an option like that for numpy. Is there something I'm doing wrong? None of the common fixes seem to be working for me. Note: I have restarted the pi and the apache2 service for each attempt, but still no luck. -

But I couldn't send an update request. I tried axios.post & axios.put methods, always got 400 Bad Request error. I even try override with id parameter in …
