Placeholder Image not Loading Correctly Using Django
I'm working on a project which displays several listings created by users. If the user who created the listing uploaded an image, it shows the image uploaded by the user, otherwise it shows a placeholder image indicating there is no image available. This is shown both on the index page which lists the available listings and in the listing itself if the user goes there. When this is done in the index page it works without problems, however, on the listing page, despite being literally the same code, it doesn't work with the placeholder image (if the creator of the listing uploaded an image it shows without problems). The urls in settings.py are: STATIC_URL = '/static/' MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') And in urls.py: urlpatterns = [ path("", views.index, name="index"), ... path("listing/<int:listing_id>", views.listing, name="listing"), ... ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) In both cases (from the index page and the listing page) if I inspect the element i'm shown: <img src="media/images/No-Image-Placeholder.png"> However, if I right click the image and choose to open it in a new window, from the index (where it works well) the address will be "http://127.0.0.1:8000/media/images/No-Image-Placeholder.png", meanwhile, from the listing (where it doesn't work) it'll be "http://127.0.0.1:8000/listing/media/images/No-Image-Placeholder.png". … -
django-cms - the pages are visible only to the administrator
The pages are visible only to the administrator. After creating the page, I can only see it if I have administrator rights. If I go to 127.0.0.1:8000 from another browser, I will only see the menu. I installed django-cms using djangocms-installer: $ python3 -m venv env $ source env/bin/activate (env) $ pip install djangocms-installer (env) $ mkdir myproject && cd myproject (env) $ djangocms -f -p . my_demo (env) $ python manage.py runserver What am I doing wrong? -

Django postgres unique constraint name generation
When adding a new unique constraint on a django model, this will automatically create a name for this constraint in postgres. Does Postgres generate this name or is it Django? Is it deterministic? for example I use this model class MyModel(Model): field1 = TextField() field2 = IntegerField() class Meta: unique_together = ("field1", "field2") I got the name of the constraint with select constraint_name from information_schema.constraint_column_usage where table_name = 'myapp_mytable' I get a name like field1_field2_d04755de_uniq -
Django 4.0 - Saving Multiple Options using ManyToManyField

How to render html text saved inside a field in the database using django?
Good evening! I created in my model a skeleton for sending personalized e-mails.

Python, Django: Trying to understand async_views (Django > 3.0)
right now I'm trying to understand how to call two models with python/django async.

IntegrityError when trying to create a one to many relationship in Python Django
I am a beginner developer, working on an app that displays some walks, and each walk should have an option for users to post reviews.

CloudCube and Boto3 - list content of the Objects
I am encountering you with the request for help with listing the objects in my CloudCube bucket. I am developing Django application hosted on Heroku. I am using the CloudCube add-on for persistent storage. CloudCube is running on AWS S3 Bucket and CloudCube provides private Key/Namespace in order to access my files. I use the boto3 library to access the bucket and everything works fine when I want to upload/download the file; however, I am struggling with the attempts to list objects in that particular bucket with the CloudCube prefix key. On any request I receive AccessDennied Exception. To access the bucket I use the following implementation: s3_client = boto3.client('s3', aws_access_key_id=settings.AWS_ACCESS_KEY_ID, aws_secret_access_key=settings.AWS_SECRET_ACCESS_KEY, endpoint_url=settings.AWS_S3_ENDPOINT_URL, region_name='eu-west-1') s3_result = s3_client.list_objects(Bucket=settings.AWS_STORAGE_BUCKET_NAME, Prefix=settings.CLOUD_CUBE_KEY) if 'Contents' not in s3_result: return [] file_list = [] for key in s3_result['Contents']: if f"{username}/{mode.value}" in key['Key']: file_list.append(key['Key']) Does anyone have clue what do I miss?

Apply django migration if constraint doesn't exist yet

Django run a command once the server starts [duplicate]

Django model tab-complete in ipython
I wish to use ipython to create a custom command-line interface to query Django model objects. So for example I'd like to type: my_models.MyModelClass.h <TAB> And have all of the elements of the MyModelClass table that start with "h" be used as the tab complete. I could achieve this by creating a startup script and creating an object heirachy which matches the table structure, however that will be slow, and I'd prefer to only create the request on demand. Is there a more direct way to use ipython's tab complete, for example a function which is called to get the tab complete list when tab is invoked? -

Django-CMS slug in if statement in HTML
I am trying to write an if statement to change what the link links to, based on the slug URL. I get an error in the if_statement. Shouldn't this work? <div> {% if page_attribute "slug" == 'hjem' or page_attribute "slug" == 'home' %} <a href="/no/">NO</a> / <a href="/en/">EN</a> {% else %} <a href="/no/{% page_attribute 'slug' %}">NO</a> / <a href="/en/{% page_attribute 'slug' %}">EN</a> {% endif %} </div> -
Django admin login wont respect custom next param
I want to redirect to a custom page (next='reports/fooreport') after Django admin login. I have a page in Django to be accessed by authenticated users. If I hit the URL let's say /reports/fooreport and I am redirecting the user to admin login with next='/reports/fooreport' using HttpResponseRedirect('%s?next=%s' % (reverse('admin:index'), '/reports/fooreport')) After successful login, Django is not redirecting to the next URL. However, it works pretty well for its internal apps like if I hit any admin page without login it appends in URL with next param and post login it redirects to this URL. Is there anything we can do to make it work?
