Django do something with each different value in a model field
I know I've seen this before, but I can't find now that I am ready to implement it. I'm trying to list items on a page by category and subcategory, but I only want 1 category and then the subcategories in the category. Hopefully my code will make sense. class Objects(models.Model): # Main Checkbox. category = models.CharField( max_length=100, blank=True, ) # Checkboxes under Main Checkbox. subcategory = models.CharField( max_length=100, blank=True, ) So my objects are stored as: category1, subcategory1 category1, subcategory2 category2, subcategory1 category2, subcategory2 And when displayed should give me: category1 subcategory1 subcategory2 category2 subcategory1 subcategory2 How do I set my query so that my results show me each "different" category? -

How should I display a notification in the Backend?
Web development projects are in progress. When the server is running, the background scheduler runs and periodically sends a GET request to the server. The server that received the GET request executes the data update operation and waits for the request again. Here, I want to show the notification on the screen while the server receives the request and processes the job. What can I do? We are developing in django. -

Django forms.ModelForm not calling init method

Where is "views.py"
Him I am trying to set up my first django project. I have never done Django before so I don't know anything about it.

Monitor videos watched using django
I am currently implementing a django project to help me with my studies. I would like to be able to monitor videos I watched (ie when? where I stopped if I did not watch it in full? how many times I watched it? ...). I don't plan to upload the videos to the database as it is several Gb of size, but to call with their path on my hard drive. Basically the features I'm looking for are similar to the ones present in Kodi for those of you which know it. I Googled for that question and could for instance found the following: How to check a user watched the full video in html5 video player But the solutions suggested make use of Javascript which I am not very familiar with. Would there be a django/python way to get the event and then just save it to the database with the videos? Thanks, Sophie -
Django rules object permissions
I am trying to use django rules to configure object permissions in django and the django admin interface. Now when I add permission rules, they will always only be called with the first param, but the object is always None. For example I if I would create this predicate: @rules.predicate def is_book_author(user, book): return book.author == user And then add it to the django permission set: rules.add_perm('books.add_book', is_book_author) Now when I log into the admin interface with a user, then the is_book_author will be called with the user and None. It will be called multiple times (once per object), but the object ist always None. I am using rules 2.0.0 with django 2.1.1 and python 3.7. Any ideas if I'm doing something wrong or how to configure django to call the predicate with the individual object? -

Deploying website with React frontend and Django rest framework backend
I am deploying my first website and currently have it running locally with React on the front end communicating with the Django backend which has a database and a rest API. I am now at the point I have been most concerned about. I need to find a way to get this onto an actual online service. Could I get some advice on what steps I need to take get this all online? And a suggestion on what services I should use? For further details this is a hobbyist website that will likely not have much traffic. However, I don't mind spending a bit of money to get it running quickly and consistently. -
Django: Transaction and select_for_update()
In my Django application I have the following two models: class Event(models.Model): capacity = models.PositiveSmallIntegerField() def get_number_of_registered_tickets(): return EventRegistration.objects.filter(event__exact=self).aggregate(total=Coalesce(Sum('number_tickets'), 0))['total'] class EventRegistration(models.Model): time = models.DateTimeField(auto_now_add=True) event = models.ForeignKey(Event, on_delete=models.CASCADE) number_tickets = models.PositiveSmallIntegerField(validators=[MinValueValidator(1)]) The method get_number_of_registered_tickets() do I need at several places in my application (e.g. template rendering). So I thought it makes sense to put it into the model also because it's related to it and I often heard it's good to have "fat models and lightweight views". My problem now: In order to prevent that two people want to register for the event in parallel, I have to use locking. Example: Let's say there's one ticket left to register for. Now, to people are on my website and click "Register" simultaneously. Under unforunate circumstances, it could happen that both requests are valid and now I have more registrations than capacity. I'm relatively new to Django, but reading through the docs, I thought that select_for_update() should be the solution, am I right here (I use PostgreSQL, so that should be supported)? However, the docs also say that using select_for_update() is only valid within a transcation. Evaluating a queryset with select_for_update() in autocommit mode on backends which support SELECT ...
