How read a file from Django when using docker?
I run Django in docker and I want to read a file from host. When I test os.stat(path), "No such a file or directory" error returned. The path is something like this '/home/user/file.txt'. Is there any idea that how can I access to host from a running container? thanks -
Django ORM group by week day and sum the day of each separately
I am having trouble to query based on weekday. This is my models: class Sell(models.Model): total_sell = models.IntegerField() date = models.DateField(auto_now_add=True) and this is my query: weekly_sell = Sell.objects.annotate( weekday=ExtractWeekDay('date'), total=Sum('total_sell') ).values( 'weekday', 'total' ) But data i am getting and it is not my expected. Like I have an entry in the table Sunday sell 4 Sunday sell 7 Friday sell 10 So i am expecting it should return these data: [ [ { "weekday": 7, "total": 11 }, { "weekday": 6, "total": 0 }, { "weekday": 5, "total": 10 }, { "weekday": 4, "total": 4 }, { "weekday": 3, "total": 0 }, { "weekday": 2, "total": 0 }, { "weekday": 1, "total": 10 }, ] ] But problem is, it not returning data that way i want, It is returning these: [ [ { "weekday": 7, "total": 4 }, { "weekday": 7, "total": 5 }, { "weekday": 5, "total": 10 }, ] ] I don't know what's wrong with this. Can anyone please help me in this case? -

Importing a table in SQLite from a .csv-file leads to unicode replacement characters
I am working on a Django (version 3.1) project and am using a SQLite3 database. I am importing tables in the database from a .csv-file. I am using SQLiteBrowser for a tool. After importing the database-table it is full of unicode replacement characters (black diamond with question mark). Prior to importing the table I saved the .csv-file with UTF-8 encoding. From the documentation I understand that SQLite databases are always UTF-8 encoded. So my feeling is that this should not happen. Now there is either something very fundamental or something very simple that I don't understand. I hope somebody can enlighten me. I don't know what else to post to illustrate my question. If need something more please ask. -

Django Heroku, server does not support SSL, but SSL was required
I have a Django application deployed to Heroku and Postgres, I'm trying to add pgbouncer to scale the app a bit, but I'm getting this error: django.db.utils.OperationalError: server does not support SSL, but SSL was required as a lot of other questions say, the problem is the SSL in django-heroku package. So I tried to approaches, first: adding to the end of setting file the following: del DATABASES['default']['OPTIONS']['sslmode'] the error is still being raised, so I took django-heroku settings function and modified it to disable SSL directly in there def custom_settings(config, *, db_colors=False, databases=True, test_runner=True, staticfiles=True, allowed_hosts=True, logging=True, secret_key=True): # Database configuration. # TODO: support other database (e.g. TEAL, AMBER, etc, automatically.) # Same code as the package # CHANGING SSL TO FALSE config['DATABASES'][db_color] = dj_database_url.parse(url, conn_max_age=MAX_CONN_AGE, ssl_require=False) if 'DATABASE_URL' in os.environ: logger.info('Adding $DATABASE_URL to default DATABASE Django setting.') # Configure Django for DATABASE_URL environment variable. config['DATABASES']['default'] = dj_database_url.config(conn_max_age=MAX_CONN_AGE, ssl_require=False) logger.info('Adding $DATABASE_URL to TEST default DATABASE Django setting.') and calling it: django_heroku_override.custom_settings(config=locals(), staticfiles=False, logging=False) but that didn't work as well, I'm still getting the original error adding Procfile just for complicity: web: bin/start-pgbouncer daphne rivendell.asgi:application --port $PORT --bind 0.0.0.0 -v2 worker: python manage.py runworker channel_layer -v2 -
How to access dynamically generated id of my HTML file in CSS and JS file associated to it
I am creating a blog page in HTML. In the backend I'm using Django. I have created a general HTML template for every post. In Django admin when I upload the image and other data, I'm getting it in Frontend and setting the id of each post dynamically using an autogenerated id coming from Backend. My HTML template is this <div class="row"> {% for blog in blogs_post %} <div class="col-sm-3 offset-sm-1 col-12" id="{{ blog.id }}"> <div class="row"> <div class="col-12"> <img src="{{ blog.image }}" alt=" {{ blog.tittle }}" class="img-fluid"> </div> <div class="col-12"> <h3>{{ blog.tittle }}</h3> <p class="d-none" id="card-body"> <h6>{{ blog.description }}</h6> </p> {% if blog.url %} <a href="{{ blog.url }}" type="submit" role="button" class="btn btn-info">Read more</a> {% endif %} </div> </div> </div> {% endfor %} </div> I want to use this id="{{ blog.id }}" In my CSS file and JS file to uniquely identify each post and apply changes to them. Like if I click one card all the cards should not expand but only the card I clicked will expand. For that I need the dynamically set id to be accessed in my CSS file and JS file. How can I achieve it please help! -

Django admin panel performance degradation
I'm facing some performance issue in admin view of my site. I am using regular Dajngo's admin panel without any special plugins and yet, when I want to open User preview it takes around 30 seconds. When investigated a bit deeper with Django Debug Toolbar I found that single User preview page requires around 270 queries, in DB where there are only 23 users total. In users list view there is only 5 queries required. According to DjDT this huge number of queries is caused by number of queries looking like this: SELECT ••• FROM "django_content_type" WHERE "django_content_type"."id" = <some number> where <some number> can change. Moreover, I see that there are 77486 voluntary, 6742 involuntary context switches. Which I suppose is just crazy big number for so small number of users. I have slightly modified User model, in a way that it is now using email instead of integer value as primary key. Other than that I have added only one integer field and that's it. Does someone has an idea what can be done to improve the performance? -

Filling in database of Django in development mode using multiple ports simultaneously
I am developing a Django project with Postgresql database. I need to scrape data from online resources and save into database while in development mode. Then, I will filter out irrelevant data for deployment and get a smaller-sized database. However, web-scraping and writing into the database is too slow (you can say the online resources are huge). I need to fill in the database faster while in development mode, using a local server. Is it possible/advisable to create multiple projects, using the same database and run them on multiple ports to fill in different sections of my database simultaneously? -

Django User Model, which one should I use, AbstractBaseUser or AbstractUser model?
I honestly do not know the difference between the two, AbstractBaseUser and AbstractUser model class. So, in my project, a website for a school, I might need the student number to be the username and I need to add more fields than just the existing fields in the default AUTH_USER_MODEL of django. I think I really need to substitute the user model (or, do I?) but what I do not know is how should I configure my custom model, should I use AbstractBaseUser or AbstractUser? Thanks! -

collectstatic collecting static files but they're not loading on webpage
I am deploying my Django site on A2 Hosting. I can get the page to display but no static files (images/css) are loading. I have this in my settings.py: ROOT_PATH = os.path.dirname(__file__) STATICFILES_DIRS = [os.path.join(ROOT_PATH, 'static')] I am running python manage.py collectstatic in the terminal. It is creating a static folder with a file structure including admin and subfolders within that admin folder. My images css files are appearing in the newly generated static file (in the base folder) yet neither the css nor my images are showing on my webpage (I've been restarting my server). My link to my css file within my html template is: <link rel="stylesheet" href="{% static 'style.css' %}" type="text/css"> Thank you. -
