Django How to display data from a view context inside a formset

How to remove the margins added by bootstrap
Im working on a page utilizing django that has a navbar plus a 3x3 grid that fills the rest of the page. My issue is when I add the bootstrap style-sheet (above my custom style-sheet) i get some white space on the right and the left of both the grid and the navbar. I assume this can be overridden by a custom style-sheet but as im learning I cant figure it out. Following advice from other posts I have messed around a lot with trying to override box-sizing (which changes nothing) and margins (which sticks everything to one side or the other but wont stretch to both sides). I assume something is constraining the size of .container but I dont know. I have used inspect element to try to isolate the problem but no luck. Here the css that works when I exclude the bootstrap stylesheet. /* Master styles*/ body { margin: 0px; font-family: 'Fira Sans', sans-serif; } .container { display: grid; grid-template-columns: 1fr; } /* Nav styles*/ #cart-icon{ width:50px; display: inline-block; margin-left: 15px; } #cart-total{ display: block; position: absolute; top: 10px; right: 20px; text-align: center; color:#fff; background-color: red; width: 18px; height: 18px; border-radius: 50%; font-size: 14px; } .nav-wrapper { … -

Count number of instances which have a parameter in a list in common
I'm building an app to keep track of a school and I'm trying to figure out how many students each course has. The way my app is structured is like this: class Course(models.Model): LEVELS = ( ('A0', 'A0'), ('A1', 'A1'), ('B0', 'B0'), ('B1', 'B1'), ('C1', 'C1'), ('C2', 'C2'), ) name = models.CharField(max_length=32) level = models.CharField(max_length=2, choices=LEVELS) class Student(models.Model): name = models.CharField(max_length=32) school = models.ForeignKey(School, on_delete=models.CASCADE) course = models.ManyToManyField(Course) So, the students in the API look something like this: [ { "id": 1, "name": "Diego", "school": 2, "course": [8] }, { "id": 2, "name": "Garry", "school": 2, "course": [1] }, { "id": 3, "name": "Dr Henrick", "school": 2, "course": [8] }, ] Now the question comes in my serializer, where I'd like to get a count for each course, ideally in a dict structure that would look something like this: { 8: 2, 1: 1} What I've done consists of getting all of the students from the db and looping over their courses list, but I wonder if I could do something like that with Django's query system. -

How to run a function with an infinite loop after rendering a page in Django
I'm writting a Django web application which will work as a tweet bot. At some point in the app the user will have to fill up a form which will decide what kind of tweets will be posted. When the user submits the form I want to render a web page to inform the user that the app is running in the background and after that I want to run the infinite loop that actually do the tweeting. My question is, how can I render a web page (from the views file) and then run the actual function (which lives in another file)? Passing the info of the form to the posting view: random_object = Random.objects.create(quotes=quotesSwitch, jokes=jokesSwitch, chuckNorris=chukNorrisSwitch, movieReview=movieReviewsSwitch, periodicityNumber=periodicityNumber, periodicity=periodicity) atributes = { 'random_object': random_object } return render(request, 'posting.html', {'random_object': atributes}) and the posting view: def posting(request): obj = Random(request.POST) random_func(obj) #This is the function with the infinite loop return render(request, 'posting.html') -

How to use the data about objects modifications in Django?
Django stores a history of the modification for every object, it is something we can access to through the Django admin: It contains data about when the object was created/modified, the user who performed the action and the timestamp of the action: By giving a look at the database, I can guess this data is stored in a default table called django_admin_log: I am wondering if we can make use of this data in any way through the instance of a model ? I got used to adding manually my timestamps on every models through an Abstract Base Class, but I am wondering if it is useful in any way ? Or this table records only the modification taking place in the Django admin panel, which would makes the custom timestamp still needed for when the models instance were to be updated outside it. -

What is a good way to store guest user information that may be saved to a permanent user after registration in django?
I have a RESTful django webapp that allows users to take quizzes in a progressive system where the quizzes become increasingly difficult. Their progress is saved when they answer a question. I'm using django-rest-framework. class User(AbstractUser): pass class IntervalsProfile(models.Model): # Belongs to User model in 1-to-1 relationship # If User is deleted, then the corresponding IntervalsProfile will be deleted as well user = models.OneToOneField(settings.AUTH_USER_MODEL, related_name='profile', on_delete=models.CASCADE) level = models.IntegerField(default=0) current_level = models.IntegerField(default=0) # Level the user is currently viewing/on I would like users to be able to play as a guest, and if they so choose, register in order to save their progress. I cannot figure out how to save this guest information or how to save it once they register. I've searched thoroughly and all the solutions I see are either several years old or seem too cumbersome (such as adding a check for authentication in every view and having 2 cases for each view). Any advice or guidance would be much appreciated. -
Open and validate files to Django (Wagtail) admin before upload
thanks in advance, I'm currently trying to create some data types which are pretty much just Wagtail's default document type (implemented on the admin similar to Django's FileField) with a custom clean (validation) method. However, the problem I'm getting is when I'm uploading the file, I get an IOError when my program tries to open the file to process. Validating the extension is easy enough, but the problem lies when I actually have to open the file. I'm guessing when I try to open it the document isn't uploaded on the server yet when it tries to validate all the information, so opening it would be impossible. I wasn't able to find any information identifying whether this is even possible, and this seemed like a core Django constraint, not just Wagtail. P.S. I'm intentionally not showing code because it doesn't really clear to much up, but if you'd like to see it I'd be happy to provide it or anything else. -

django - DecimalField max_digits, decimal_places explained
So I'm just starting out with Django and using it to store forex prices which are represented as 1.21242, 1.20641, etc... model.py from django.db import models # Create your models here. class ForexPrice(models.Model): openPrice = models.DecimalField(max_digits=6, decimal_places=6) highPrice = models.DecimalField(max_digits=6, decimal_places=6) lowPrice = models.DecimalField(max_digits=6, decimal_places=6) closePrice = models.DecimalField(max_digits=6, decimal_places=6) My Question Is: How do the max_decimal and decimal_places attributes work? I'm using 6 for both fields assuming max_digits=6 will allow values to be stored up to 6 digits ie: 123456.000000 while decimal_palces=6 will support values up to 000000.123456. Is this assumption correct or am I missing something? Getting the following error when I save the record to the DB: A field with precision 6, scale 6 must round to an absolute value less than 1.
