Cannot import Django
During an online course, I came across this error! According to the error, Django isn't available on my machine. Tried reinstalling the same, but got the same error! Was checking for errors when I came across this error in VS code. Tried various solutions found online but to no avail. Please help! -
Set Apache to prompt a password for a Django site?
I have a Django wsgi site that I would put online soon. I would rather the site to not be accessible except through an Apache login prompt until it is ready. I investigated and found limited or outdated information about how to do it (which I tried anyway). There is more information to make it work with a plain Apache served webpage and I was able to made it work on my default Apache welcome page, but Django seems less documented in that regard. For example I added something like this in my .conf file: <Directory "/path/to/djangosite"> AuthType Basic AuthName "Restricted Content" AuthUserFile /etc/apache2/.htpasswd Require valid-user </Directory> where /path/to/djangosite is where wsgi.py resides. Password was set in .htpasswd successfully. How are you all doing this? -
Unwanted glassy border outside of background images
I'm using Django, HTML and CSS to build a website to post some pictures, but I'm fairly new. I'm using a <div> with backgound-image style to load picture on a website. For some reason, every picture is loaded with some border radius (even though I don't have any in my CSS) and it has this weird glassy-looking border, some of the pictures also have a black line among some of the borders. Here is how it looks like. My html file: <div class="container"> <div class="photo-grid"> {% for i in image|dictsort:'pub_date' %} {% if i.is_tall == True and i.is_wide == False %} <div class="card" style="background-image:url('{{i.image.url}}')"> {{i.title}} </div> My CSS file: .container { display: flex; justify-content: center; justify-items: center; } .photo-grid { display: grid; gap: 1rem; grid-template-columns: repeat(auto-fit, minmax(240px, 1fr)); grid-auto-rows: 240px; margin-top: 75px; margin-bottom: 3vw; width: 1500px; } .card { display: flex; flex-direction: column; justify-content: center; align-items: center; height: 100%; width: 100%; overflow: hidden; background-size: cover; background-position: center; background-repeat: no-repeat; } I have no idea what could be wrong with it. I tried deleting random lines of CSS, but nothing seemed to be working. -

When setting use multiple databases getting error settings.DATABASES is improperly configured
I am trying to setup multiple databases in django and I am getting error message when trying to submit information using website form. The web form still submits data but shows error message.

What is the most Django-appropriate way to combine multiple database columns into one model field?
I have several times come across a want to have a Django model field that comprises multiple database columns, and am wondering what the most Django way to do it would be. Three use cases come specifically to mind. I want to provide a field that wraps another field, keeping record of whether the wrapped field has been set or not. A use case for this particular field would be for dynamic configuration. A new configuration value is introduced, and a view marks itself as dependent upon a configuration value, redirecting if the value isn't set. Storing whether it's been set yet or not allows for easy indefinite caching of the state. This also lets the configuration value itself be not-nullable, and the application can ignore any value it might have when unset. I want to provide a money field that combines a decimal (or integer) value, and a currency. I want to provide a file field with a link to some manner of access rule to determine whether the request should include it/a request for it should succeed. For each of the use cases, there exists a workaround, that in each case seems less elegant. Define the configuration fields … -

PyCharm doesn't recognize user instance when using custom user model in Django

How to send ImageFieldFile objects fetched from the database by django to the front-end and display them
When using django as a backend, I have an image saved in the database in ImageField format, and in the view layer I get the object via orm, how can I return it to my vue frontend. I turned the ImageField object into a string to return a JsonResponse, but the front-end only gets the name of the image when it's read def getContent(request): mtitle=request.GET.get('title') row_obj=models.content.objects.filter(title=mtitle).first() res={ "pic":str(row_obj.img), } print(type(row_obj.img)) return JsonResponse(res, json_dumps_params={"ensure_ascii": False}) How do I request the image to be displayed on the front end?
