Setting time field in django such that the stored time cannot be changed later
I have a orders model which looks like this: class Order(models.Model): customer=models.ForeignKey(Customer,on_delete=models.SET_NULL,null=True,blank=True) date_ordered=models.DateTimeField(auto_now=True) complete=models.BooleanField(default=False,null=True,blank=False) and this is a specific view from my views.py: def handlerequest(request, id): order=Order.objects.get(id=id) items=order.orderitem_set.all() verify = Checksum.verify_checksum(response_dict, MERCHANT_KEY, checksum) PaytmHistory.objects.create(**response_dict) if verify: if response_dict['RESPCODE'] == '01': order.transaction_id=transaction_id order.complete=True order.save() print('order successful') Now what is happening is that whenever this is view is called the order is saved and the time updates to when the order was saved. But in future when I manually make some changes to the fields like when I update the shipping status of the order and save it then the time updates which I dont want . So is there any fix to this such that after order.complete=True order.save() The time cannot be changed -
Do I need to write the full media path in Django?
I am trying to download a file that is stored in the media folder and it seems as it only works when I am writing the full path as: file_location = '/home/user/user.pythonanywhere.com/media/' In the settings page on pythonanywhere, the 'media url' points to the same directory. So I don't really understand why I just can't write /media/ instead for the full path. Has it something to do with my settings.py file? I have these lines there: MEDIA_ROOT= os.path.join(BASE_DIR, 'media') MEDIA_URL="/media/" Do I need to have these lines at all? -

Django Filter in View or HTML
I am working on a basic assignments project where the teachers can add assignments and the students can submit the answers. I have saved it with models Assignments and Submissions as shown in the code below. The thing I am trying to do is that I want to show different buttons with different links when a parent has submitted the assignments. To be exact I want to show "Add submission" if a parent has not submitted and "Update Submission" when he/she has submitted already to a particular assignment. The problem I am having is that when a parent submits to a certain assignment then other parents also see "Update Assignment" if I give some filtering on the querysets. How can this be handled? Is there something we can do in html or some other filtering in views.py? Or I have to change by style of doing this. Please your support will be a great help.

Django How to save JSON data outside a view in a session and retrieve the saved data inside the view?
I have JSON data which I want to store uniquely for each user inside a session. The problem is, the module which generates the JSON data is async is outside the Django view because it is very resource demanding. I want the JSON data this separate module generates to be stored in a session so that the data is unique for each user. I have tried the following outside my view module: from django.contrib.sessions.backends.db import SessionStore s = SessionStore() s['json_data'] = json_var s.save() But when I try to read the saved session data back inside a view, it loads nothing e.g. it doesn't go inside if statement: if 'json_data' in request.session: json_var = request.session['json_data'] Is there an elegant way to do this? -
Django API returning a single object rather than my whole list when using Table.objects.filter(condition)
In my Django project I have two tables: User and Post, where each Post has a foreign key 'author' to a User. I want to display all the posts that belong to a single user, with the URL: .../users/<int:pk>/posts. I parse this into my view function with the header: def user_post_list(request, pk):, which to my knowledge gives my view function access to this int:pk variable. I define the posts I want to return using posts = Post.objects.filter(author=pk), which should give me a list of all the objects that have an 'author' attribute equal to int:pk. However, when I go to return these posts, rather than a list I get only one JSON object from the Post table with an 'id' attribute and 'author' attribute equal to int:pk Thanks -

Django REST file upload results in different file size than original
When using Django REST Framework to handle file uploads using the FileUploadParser and storing the file on disk, is it normal for the final stored file (on the Django side) to have a different file size than the original file? I'm a newbie to Django (and Python in general) - my second week doing Django. I have a Python 3 script on a server (Ubuntu) that periodically uploads zip files to the Django (3.1) server using the Django REST Framework, also on Ubuntu. Using Python 3.8 on both sides. In each upload event, the file is always a single zip file (which only contains .txt and/or .csv files). The file upload is simple and is stored on disk on the Django side. From the sending side, I have experimented with a simple Python 3 script and curl as well, with differing results - the transferred files are always bigger than the original, and different between curl and my Python script. I am able to unzip and inspect the contents without issue; the text and csv files are identical in all cases. Needless to say, when I do a simple sftp, bypassing Django, the file size is identical - this is … -

Im trying to let user create a post and select a category, but when it selects a category and I post it, it gives me the error: Exception Value: 'NoneType' object has no attribute 'add'. If i go to my database, whatever I type, it is save except the category_id which is null. This is my code views.py: @login_required(login_url='login') def userposts_create_view(request): form= UserPostForm(request.POST or None) if form.is_valid(): data = form.cleaned_data categories = data.pop('categories', None) user_post = UserPost.objects.create(**data, user=request.user) if categories: user_post.categories.add(*categories) return HttpResponseRedirect("/posted/") context= {'form': form} return render(request, 'posts/userposts-create-view.html', context) #list view @login_required(login_url='login') def userposts_list_view(request): allposts= UserPost.objects.all() context= {'allposts': allposts, } return render(request, 'posts/userposts-list-view.html', context) #detail view @login_required(login_url='login') def userposts_detail_view(request, id=None): post= get_object_or_404(UserPost, id=id) context= {'post': post, } return render(request, 'posts/userposts-detail-view.html', context) I assume the error must be in the models but not sure...
