Django. Conditional model field in admin form (Either link to image or upload image)
I don't know how to do kind of conditional field in model's admin form. I want a model that has multiple images that can be either uploaded or linked from another site. I came up with separate link and upload_file fields and choice field type and then conditionally handle and save it to the database but that approach looks very bad. It makes me to create custom save logic (which i don't know how to do) and it adds extra info into the database. I started to learn django just today, please, add simple solutions not touching django's advanced usage -

Django inconsistent queries on oracle DB
i'm having really hard times debugging some queries in my project. They look like this: hosts = Hosts.objects.filter(...) query = reduce( operator.or_, ( Q(packages_set__name=name, packages__version__in=versions) for name, versions in some_versions_dict ) ) hosts = dc_hosts.filter(query).annotate( num_packages=Count('packages_set') ).filter( num_packages=len(some_versions_dict) ) and they run really inconsistently, sometimes they finish just fine and sometimes they stay stucked and does not finish. I expect it has something to od with this because I don't really know how to fix that so I just use queries later in a way which does not trigger it (.values_list(...)). Is there some other way how to solve my previous question or is there any way how could I fix it for my db? Thanks for you help this is work related and its driving me crazy currently. -

Django Static Files(CSS) don't link with template
Just as the title says, static files somehow are not loading up in my template. I've tried working on it and looking at similar StackOverflow questions but I can't find a solution. I tried debugging it using browser's dev tools. I tried opening the CSS file from there but it just leads me to this error. This leads me to the conclusion that Django doesn't seem to find base.css inside the static folder. I've already done manage.py collectstatic so there shouldn't be a problem. Thanks! Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/static/static/base.css 'static\base.css' could not be found You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page. settings.py # Static files (CSS, JavaScript, Images) STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static/') template {% load static %} <link rel="stylesheet" type="text/css" href="{% static 'static/base.css' %}"> -

Can I use edit django cms PlaceholderField before saving (publishing) my page outside of django cms?
I use the placeholder fields outside of the regular django cms. I wish to edit placeholder fields before publishing something. The documentation states: However, any PlaceholderFields in it will only be available for editing from the frontend. And: If you add a PlaceholderField to an existing model, you’ll be able to see the placeholder in the frontend editor only after saving the relevant instance. The only solution I can think of to edit the placeholder is adding a stage of published/unpublished and make unpublished only visible to some with the right access. Or is there a way to "hack" placeholder editing in the admin field? Or some other solution?
