Data too long for column when creating user
By going to url(r'api/users/', views.MyUserCreate.as_view(), name='user-create'), one can see DRF Browsable API which uses MyUserCreate (in views.py) class MyUserCreate(APIView): """ Creates the user.

Vertically Assignment of Block in Page
I am learning DJANGO and while proceeding wanted to give nice look to some pages. I am currently new in programming (only 4 months coding) and mostly spent time with Python, could find time to properly learn front-end. So my problem is I can`t center LOGIN block in the page. I am using Bootstrap4.5 and gave some Shadow to make object like floating. I now there were similar questions here with answers and tons of tutorial of centering elements either with custom CSS or Bootstrap Flex or Justify and I really tried almost everything I found with no result. Every time time position of Block is getting somewhere else but not center.

Setting up one custom logger for the entire django project
This is how i'm configuring logger in my Django project currently In settings.py file import os import logging.config from django.utils.log import DEFAULT_LOGGING logger = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'dark': { 'format': '{asctime} {name} {levelname} {message}', 'datefmt': '%d-%b-%y %H:%M:%S', 'style': '{', }, }, 'handlers': { 'file': { 'level': 'DEBUG', 'class': 'logging.FileHandler', 'filename': 'logs.log', 'formatter': 'dark' }, }, 'loggers': { 'darkbot': { 'handlers': ['file'], 'level': 'DEBUG', 'propagate': False, }, }, } logging.config.dictConfig(logger) The logs are getting written in the file as expected but the problem which i'm encountering is the name of the module in logs remain constant doesn't matter by which module that log is get written For instance if i use this logger = logging.getLogger("darkbot") logger.info("started reading new file") Then my log looks some thing like this 30-May-20 12:22:56 darkbot INFO started reading new file As you can see i'm getting darkbot as the name of the module which is constant.

Optimize DB requests in Django
I have a page view in Django set up as follows: blog = get_object_or_404(Blog, subdomain=extracted.subdomain) all_posts = Post.objects.filter( blog=blog, publish=True).order_by('-published_date') nav = all_posts.filter(is_page=True) posts = all_posts.filter(is_page=False) This causes the DB to be accessed 3 times. I'm trying to optimize this to only access the DB once. The following snippet reduces the number of calls to 2, but I'm sure there is a better way than this that I don't know about. blog = get_object_or_404(Blog, subdomain=extracted.subdomain) all_posts = Post.objects.filter( blog=blog, publish=True).order_by('-published_date') nav = [] posts = [] for post in all_posts: if post.is_page: nav.append(post) else: posts.append(post) As far as I understand, prefetch_related and select_related work inversely and I'm unsure how to implement them in this context. My models are set up as follows: class Blog(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, blank=True) title = models.CharField(max_length=200) ... class Post(models.Model): blog = models.ForeignKey( Blog, on_delete=models.CASCADE, related_name='post') title = models.CharField(max_length=200) ...

Static Media Failure with NGINX and Gunicorn
Hello and thanks for taking time to read this request for help. I am installing a web application called Netbox, which is built on Django. A basic Gunicorn is front-ended with NGINX in a rather simplie configuration. The problem I'm running into is that the web application reports that it is unable to load any of the static files, and I can validate that I'm getting a 404 for these requests. I have validated that I can view the correct files in the /static/ path referenced in the NGINX path /opt/netbox/netbox/static, and the permissions are correctly set as well. Since this is a Django web app, I have performed a simple test with the built-in test web server and all the static files are correctly rendered; this is almost certainly an issue between Gunicorn and my NGINX configuration. nginx.conf server { listen 443 ssl; # CHANGE THIS TO YOUR SERVER'S NAME server_name netbox.example.com; ssl_certificate /etc/ssl/certs/netbox.crt; ssl_certificate_key /etc/ssl/private/netbox.key; client_max_body_size 25m; location /static/ { alias /opt/netbox/netbox/static/; } location / { proxy_pass http://127.0.0.1:8001; proxy_set_header X-Forwarded-Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Proto $scheme; } } server { # Redirect HTTP traffic to HTTPS listen 80; server_name _; return 301 https://$host$request_uri; } gunicorn.py bind = … -

Apache HUE, can login using REST API, but the rest doesn't work
I'm struggling with Apache HUE Rest API and django csrf. The problem is that I can kind-a login, but the rest doesn't work. I always get redirected to login page. Seems like server doesn't like my csrftoken or sessionid cookie. I have absolutely no idea why. Here is my login code: val accessToken = getAccessToken(Http(s"$baseUrl/accounts/login/?next=/").asString) val response = Http(s"$baseUrl/accounts/login/") .postForm(Seq( "username" -> username, "password" -> password, "csrfmiddlewaretoken" -> accessToken.csrftoken.getValue, "next" -> "/" )) .cookie(accessToken.csrftoken) .asString getAccessToken(response) // wrapper for cookies and headers from response Now I try just to get page from HUE protected with csrf def getDir(hdfsPathDirParent: String): Unit = { val accessToken = login() val response = Http(s"$baseUrl/filebrowser/view=$hdfsPathDirParent") .cookie(accessToken.csrftoken) // retrieved after login .cookie(accessToken.sessionid) // retrieved after login .header("X-CSRFToken", accessToken.csrftoken.getValue) .header("Host", "localhost:8888") .header("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9") .header("Connection", "keep-alive") .header("Sec-Fetch-Dest", "empty") .header("Sec-Fetch-Mode", "cors") .header("Sec-Fetch-Site", "same-origin") //.header("Sec-Fetch-User", "?1") .header("Upgrade-Insecure-Requests", "1") .header("User-Agent", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.61 Safari/537.36") .header("Accept-Encoding", "gzip, deflate, br") .header("Accept-Language", "en,en-US;q=0.9,ru;q=0.8") .header("Cache-Control", "max-age=0") .header("X-Requested-With", "XMLHttpRequest") .asString I literally copy-pasted all tokens from Google Chrome debug panel.

Scraping gets blocked, gets response of a buffer reader
So i have been building a Django App using Beautiful soup to scrape a website and it was working perfectly in development.

Django and FCM to send push notifications
What's the correct way to use fcm-django using a custom Device-info model or a possibility to extend FCMDevice with more attributes. For example, I need to store into the device info some additional fields like language, position (lat/lng), app version, vendor etc. I'm new for FCM but for me, at the moment, It's not very clear the device registration flow. My current project is a backend service for mobile apps. So, I have some REST service using djnago-rest-framework. I already have an API to register/update a mobile device. Can I reuse it adding the FCM registration-id? -

Django Angular images not loading from AWS S3
My Django-Angular app works fine, but without static images. I run "ng build --prod" to the Django static folder and uploaded these files to AWS S3 Bucket. My Index.html file in Django Template is loaded and the page displayed. My Settings.py: AWS_ACCESS_KEY_ID = '*******' AWS_SECRET_ACCESS_KEY = '******' AWS_STORAGE_BUCKET_NAME = 'mys3bucket' AWS_S3_REGION_NAME = 'eu-central-1' AWS_LOCATION = 'static' DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' STATICFILES_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' AWS_DEFAULT_ACL = None STATIC_URL = 'https://' + AWS_STORAGE_BUCKET_NAME + '.s3.amazonaws.com/' STATICFILES_DIRS = ('static'), In my angular App I have a src/assets dir. When building the app I used paths for images like: <img src="static/assets/png/Logo1.png"> this worked fine. Now they are in S3 and I thought that the path will be automatically set to "Static_Url" from Django settings.py.

Django static files are not loaded when deploying on Heroku using Whitenoise
I'm trying to deploy a django app on Heroku (using Whitenoise), and all works fine except for the static files. The sample project just shows a header "Home" on the front page. If the css file is loaded correctly then the header will have the red colour, otherwise it will be black. I got the above project to work in a virtualenv, a Docker container, with DEBUG=False, but I could not make it work on Heroku for some reason. I tried to use the django-heroku as suggested by the Heroku docs but it starts throwing 500 server error, and when checking the heroku logs it says manifest not found for the css file, which seems to be because it sets STATICFILES_STORAGE to a different value. Is there something setup incorrectly in the settings or the yml files? -

waypoints infinite scroll doesn't append newly loaded items to the infinite-container in django
The code works just fine while performing a standart pagination, but when I update it to infinitite pagination using waypoint-jquery it triggers the waypoint function which also is able to trigger views.py function and data is sent to the html side. But the newly loaded items are not appended to the infinite-container. {% extends "layout.html" %} {% load static %} {% block body %} <h1 class=yazar>{{yazar}}</h1> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.
