Django allow anonymous ajax request to access a Generic View
This is what I've got so far: from django.views.generic import View from django.views.decorators.csrf import csrf_exempt class ConfigurationView(View): @csrf_exempt def dispatch(self, *args, **kwargs): return super(ConfigurationView, self).dispatch(*args, **kwargs) def get(self, request): ... However, when I make an ajax get request to this view I am not able to access the get method function getCookie(name) { let cookieValue = null; if (document.cookie && document.cookie !== '') { const cookies = document.cookie.split(';'); for (let i = 0; i < cookies.length; i++) { const cookie = cookies[i].trim(); if (cookie.substring(0, name.length + 1) === (name + '=')) { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); break; } } } return cookieValue; } $.ajax({ url: "https://{{ domain }}/configure", headers: { 'X-CSRFToken': getCookie('csrftoken') }, crossDomain: true, data: { email: "{{ email }}", }, dataType: "json" }) I think I am sending the csrftoken correctly and I shouldn't really need the csrf_exempt, but either way the request gets a redirection to the login page. Any help would be highly appreciated. -

django-filters multiple related fields: filter down the fields
I am using django-filters module to filter my table. I can filter the data but can not bind the fields. After I filter by one field, another field should contain only related values. Table I am filtering As you can see in the picture when I filter by the field "Şube", I can see the related values that should be contained by "Kaynak" field on top but "Kaynak" dropdown still contains all its values.

The proper way of getting the value of a TimeField in Django
Imagine that in a Educational Management System I have created a form for entering the details for a ,let say, course. After I save it to the database(in my case postgres) I want to provide the user with the opportunity to edit the previously saved form. So I have to initialise a form with the initial values that user has previously entered. Everything is Alright but the problem is that I cannot format the the TIME input (let say the time that course starts) received from the database into a proper shape to be suitable for in my html. So the initial value is not shown in the time input.How can I solve this problem? -
how to prevent user from going back to form (all forms login, edit post, etc.) after submission in django?
I'm new to django and I'm stuck with a problem. Please help me solve it. Problem: Whenever I fill a form, be it a login form, edit post form, create post form, etc..If I press browser's back button, It takes me back to it. What I want: Redirect the user to somewhere else rather than taking them back to form. Is there any way to perform it in django ? I want to use CBVs only "and yes, I don't wanna disable browser back button !"

Using Django F expression with Case, When expression
I have a Django model like # app/models.py class tbl_invoice(models.Model): invoice_id = models.IntegerField(blank=True, null=True) client_id = models.ForeignKey(tbl_customer, on_delete=models.CASCADE) invoice_number = models.IntegerField(blank=True, null=True) date = models.DateField(blank=True, null=True) amount = models.DecimalField(max_digits=8, decimal_places=2, blank=True, null=True) paid_amount = models.DecimalField(max_digits=8, decimal_places=2, blank=True, null=True) balance = models.DecimalField(max_digits=8, decimal_places=2, blank=True, null=True) date_of_payment = models.DateField(blank=True, null=True) status = models.CharField(max_length=50, default='', blank=True, null=True) I have another view in which I am saving payment record, I want to update status as Paid or Unpaid depending on if the difference between the user-entered amount and balance is 0 or not currently, this is what I have done #app/views.py if form.is_valid(): post = form.save(commit=False) # rest of the logic goes here post.save() # this data is saved in another model, after that I update invoice model tbl_invoice.objects.filter(invoice_id=someIdHere).update(paid_amount=F('paid_amount')+post.amount, date_of_payment=post.date, balance=F('balance')-post.amount, status=Case( When(balance=F('balance')-post.amount==0, then=Value("Paid")), When(balance=F('balance')-post.amount!=0, then=Value("Unpaid")), )) this query is updating status as blank. however, using only the F expression to update amount and balance is working fine tbl_invoice.objects.filter(invoice_id=someIdHere).update(paid_amount=F('paid_amount')+post.amount, date_of_payment=post.date, balance=F('balance')-post.amount the above statement is working fine surely I am making some obvious mistake that I can't figure out. How can I use the F expression with Case?? -
Python - \x characters while reading from an uploaded file
I am using python3.6 and django 2.2.6 in the backend. I am uploading a .odt file without any encoding. When I do this print(type(request.FILES['labfile'])) print(request.FILES['labfile'].read()) It gives me <class 'django.core.files.uploadedfile.InMemoryUploadedFile'> And this: https://pastebin.com/4WiueuMb The original contents of the odt file is https://pastebin.com/6qT1XWJR I tried doing request.FILES['labfile'].read().decode("utf-8") and I got 'utf-8' codec can't decode byte 0xd2 in position 12: invalid continuation byte I thought \x could mean hex and tried decoding using .decode("hex") and codecs.decode() but that didn't work either. Now it seems like the data is somehow related to xml, but I am not having any idea of how to decode. Any leads are highly appreciated and thankful. Thanks in advance. -

DB design and ideas for a webserver management system
I'm working on a "(web)server management system" for my local webserver, to learn django on something useful. (Maybe when it's done and other people will be interested, I'll release that as an open source project.) My problem is, I'd like a real-time graphs for CPU/RAM usage and CPU temperature and also history graphs. For the real-time I'd get the data every second, saved it and send it via websockets to clients. But, I dont want one big table of values per second, cos in one year it would have 31.5M rows, that's too much :) So for the history data I probably need just average,max and min values per day (?) But also when I reach some percentage (for example 70%), I should have a log of processes that were consuming the cpu/ram. So I'd have probably a per_sec table, which I'd truncate at midnight after I saved the average,max,min values to a per_day table. Plus I'd have a peaks and peaks_processes tables. Also I'd use some in-memory db for the last 10seconds values - to faster serve the websockets. Or does anybody have any better ideas for the db design? And what else might a real server admin be … -

Added more fields to a form but the changes aren't showing up
Title pretty much sums it up. I added some new fields to a form that a group member created, but when I runserver I can't see the changes. I render it in the view, changed the form in forms.py, added the view to urls.py, tried linking it to a model (idk why this would work, but a TA suggested it).

How to pass request.user with a ManyToMany Field in Django
I have two models Exercise and Area, Area has a manytomanyfield back to Exercise: class Exercise(models.Model): user = models.ForeignKey(Profile, on_delete=models.CASCADE) name = models.CharField(max_length=100) class Area(models.Model): user = models.ForeignKey(Profile, on_delete=models.CASCADE) name = models.CharField(max_length=100) exercise = models.ManyToManyField(Exercise, blank=True) I want the user to be able to create a new exercise that automatically attaches to its specific area, and also passes in request.user.

Now when I try to submit the form nothing happens. No errors, and no objects are created. I have tried new_ex.user = self.request.user and form.instance.user = self.request.user and still nothing happens. Btw my user attributes are a ForeignKey to the auth user model: from django.contrib.auth.models import User class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) -
django-reversion - Add django admin filter for at least one changed version
