Django, Python: cannot unpack non-iterable int object
I have tried to figure this out by looking at the same questions asked by others but I could not figure it out by looking at their questions. Is it something wrong with the vote views of is it something else. The problem is everytime I hit the vote/submit button I get this error can someonne explain the reason for this. views.py class QuizView(DetailView): model = Question template_name = 'Quizzes/quiz.html' class ResultsView(generic.DetailView): model = Question template_name = 'JSUMA/results.html' def vote(request, question_id): question = get_object_or_404(Question, question_id) try: selected_answer = question.answer_set.get(pk=request.POST['answer']) except (KeyError,Answer.DoesNotExist): return render(request, 'Quizzes/quiz.html', {'question':question, 'error_message' : "You didn't select an answer.",}) else: selected_answer.ans += 1 selected_answer.save() return HttpResponseRedirect(reverse('JSUMA:', args=(question.id))) models.py class User(models.Model): first_name = models.CharField(max_length=25) last_name = models.CharField(max_length=25) #password = models.CharField(max_length=25) email = models.EmailField(max_length=100) class Quiz(models.Model): name = models.CharField(max_length=200,primary_key=True) NOQ = models.IntegerField(default=1) class Meta: verbose_name = "Quiz" verbose_name_plural = "Quizzes" def __str__(self): return self.name #number Of Questions class Major(models.Model): major = models.CharField(max_length=200) ans = models.IntegerField(default=0) answer = models.ManyToManyField('Answer') def __str__(self): return self.major class Question(models.Model): question_text = models.CharField(max_length=400) quiz = models.ForeignKey("Quiz", on_delete=models.CASCADE, null=True) def __str__(self): return self.question_text class Answer(models.Model): question = models.ForeignKey('Question', on_delete=models.CASCADE, null=True) answer_text = models.CharField(max_length=200) def __str__(self): return self.answer_text quiz.html <h1><h1>{{ question.question_text }}</h1></h1> {% if error_message %}<p><strong>{{ error_message … -
Django form is sent but doesent save to database
I´m doing a simple user-business application, where a user has one or many business. The problem is that my create business forms is not saving its data to the database.

Django post primary key as slug? How do I reference the primary key in models.py?
When creating the slug for my post model, I want to use the object's primary key as the slug. However when I create a new post, instance.id is NoneType and not an integer like I'd imagine. Here is my model: class Post(models.Model): id = models.AutoField(primary_key=True) title = models.CharField(max_length=50, null=False, blank=False) body = models.TextField(max_length=5000, null=False, blank=False) image = models.ImageField(upload_to=upload_location, null=False, blank=False) date_published = models.DateTimeField(auto_now_add=True, verbose_name="date published") date_updated = models.DateTimeField(auto_now=True, verbose_name="date updated") author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) slug = models.SlugField(blank=True, unique=True) def __str__(self): return self.title @receiver(post_delete, sender=Post) def submission_delete(sender, instance, **kwargs): instance.image.delete(False) def pre_save_blog_post_receiver(sender, instance, *args, **kwargs): if not instance.slug: instance.slug = slugify(instance.id) pre_save.connect(pre_save_blog_post_receiver, sender=Post) As you can see in pre_save_blog_post_receiver, instance.id returns as None. How do I correctly reference the primary key in this situation? -
Django Import Export - is not importing fields from csv file
I am following a very simple tutorial from SimpleIsBetterThanComplex. on how to integrate Django Import Export and having issues with the csv data populating the database.

Is it safer to user Integer PrimaryKey + Hashing or use secrets module without hashing
I am trying to create an application that requires some sensitive data. Now inside my database, I am using the python secrets module to create a safe 16-byte hex token for each object. However, by doing so I will not be able to hash it as it's not an integer anymore. So I was wondering if I use the secrets module will it be safe enough to expose the id's to the end-users? so for instance I have a field for one of my tables in my database such that: id = secrets.token_hex(16) which for instance would return id = cf125cf14d4ae9ed8972ee7512755e6d Or should I stick to the regular database primary keys which are auto-incremented integers and then use a hashing library to show the hashed value and then just decode those when I want to use them? -

Trouble passing foriegn key to form to filter for that key

Run a function when the browser is closed Django
Based from what I've read there is no way of learning if the browser or a tab is closed by the user through Django. Ideally I think there should be no problem in closing the browser or a tab because the user is automatically logged out. However, my problem is I have overridden my log-out view so Django does some functions (such as saving a time-stamp, and etc.) regarding the models relating to the logged in user. Django does not fire up these functions whenever the user logs out through closing the browser. It runs though when the user logs out normally through the "Log-Out" button. This is my overridden log-out view: def logout(request): reset_logged_acc(request) #do something auth_logout(request) #custom log-out return redirect('home') I've read somewhere that I can do some ajax requests and what not to know if the user is still there. I think its possible but I'm putting that option up as a last resort if nothing comes up. Are there any alternative ways to implement this? -

deploy to heroku: ProgrammingError: cannot cast type uuid to integer
I just attempted to deploy a new app to Heroku and I am running into an error I can't seem to figure out. Heroku or Django currently thinks I am trying to cast UUID to an Integer. I know the error is the result of bad logic inside my models but I don't know how to fix it. The answers to everything else I have seen tell the OP to just change Primary_Key = True. I cannot do this as I need my id to auto increment , which is currently the Primary Key. So for my id field I am using AutoField to increment automatically. I believe Django makes your id auto increment by default but I wrote it out anyways. If changing model structure is the only solution, then I guess I'll have no choice though. class Order(models.Model): STATUS = ( ('Pending-Approval', 'Pending-Approval'), ('Approved', 'Approved'), ('Rejected', 'Rejected'), ('In-Progress', 'In-Progress'), ('Complete', 'Complete'), ) id = models.AutoField(primary_key=True) customer = models.ForeignKey(UserProfile, null=True, on_delete=models.SET_NULL) panel_type = models.ForeignKey(PanelType, null=True, on_delete=models.SET_NULL) description = models.CharField('Customer Description', max_length=264, null=True) date_created = models.DateTimeField('Date Created', auto_now_add=True, null=True) status = models.CharField('Job Status', max_length=200, null=True, choices=STATUS, default="Pending-Approval") address_st_one = models.CharField('Street 1', max_length=264, null=True) address_st_two = models.CharField('Street 2', max_length=264, null=True, blank=True) … -
How can i format a json field in Django admin?
I would like to implement a rewards system in my django project, where a user would have badges that would be displayed on their profile, and could be edited via the admin.

Django record that has many 'files' attached to it. How to do that in a form with the models
I am just not sure the name of what I am trying to do to google on my own (even though this is django and I had some experience in rails back in the day, it sounds like a partial form?) I am thinking what I need should be pretty simple and cut and dry..... I have a model to store information on an instrument. Then this instrument model can have many files associated with it (pdfs that are uploaded, pngs, zips etc). I can get the form created using crsipy forms and that easy enough... (attached is the form of the Technical_Entry model just has nothing attached for the files). I would love to have something that says like Files: On the form then has plus where clicking that uploads a file to that Technical_entry record, then after it is uploaded that file is available to be clicked on and downloaded again. Or a minus to remove the file from the entry.... I just am not sure how to connect that (essentially a secondary model) to the firs model/form? class Technical_Entry(models.Model): category = models.ForeignKey(Category, on_delete=models.CASCADE) ema = models.ForeignKey(EMA, on_delete=models.CASCADE) system = models.ForeignKey('System', on_delete=models.CASCADE) sub_system = models.ForeignKey(SubSystem, on_delete=models.CASCADE) drawing_number = … -
CSRF middleware token missing?
I'm novice adapting a simple address book database program using Django from a course I've done on Codemy. I have a page where I enter the names, surnames etc together with a DELETE and EDIT button next to each address.

The btn1 is the name="btn1" of the button as indicated.

Not even sure if the issue is with the token? I've gone through the tutorial time and again and cannot see an issue. I'm a noob, so any info would be great! -
Django signals not returning data when using celery
I have a Django signal which takes the content of some order data and outputs it to a text file on an Azure blob. I have been trying to run the signal using celery and the task executes fine. However the output is not written to the text file. The code works fine if running it solely as a Django signal. For some reason, my queryset doesn't load any data using celery.

Django cannot locate static files for the index page of the website
So, in my index page located in root/templates/home.html I have the following line for loading CSS: <link rel="stylesheet" href="{% static 'project/home.css' %}"> home.css is located at: root/static/project/home.css In settings.py: STATIC_ROOT = "static/" STATIC_URL = '/static/' And when I run the server, in the main page CSS fails to load raising 404 in the browser although the browser displaying the correct path where the home.css is located: http://127.0.0.1:8000/static/project/home.css For all apps in the projects everything works fine. When global static is defined in settings.py: STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'static'), ) the problem is solved, but then, for obvious reasons I cannot perform collectstatic unless I rename it to "assets" for example. I am clearly missing something here but I want to know why it fails to load the home.css from the legit path? -

Fetch calls to Django fail in Safari 11
I have a Django Rest Framework app that I am communicating with via the use-http module: const request = useFetch('', { headers: { 'Content-Type': 'application/json', 'X-CSRFToken': Cookies.get('csrftoken'), }, cachePolicy: 'no-cache', credentials: 'include', }) ... request.get('/api/users/status/') .then(res => console.log(res)) .catch(err => console.log(err)) This works perfectly, except in Safari 11 (and mobile Safari 11), where the result is a 403 forbidden error. I am using session authentication, and I have verified that the CSRF token is correct and being sent with the request. However, I did note that the Django sessionid cookie is never set after login. My front end is on the same domain as the back end, with the API accessible via /api/, so I don't believe I should be having CORS issues. I have tried changing the CSRF_COOKIE_SAMESITE and SESSION_COOKIE_SAMESITE Django settings. -
