Django UpdateView AttributeError 'UserPostUpdateView' object has no attribute 'publish'
I get the error when I try to save the form after editing. If I override get_context_date(currently commented out), I get the error when loading the form. I've looked at the documentation and previous questions with this problem. Those who ran into this had overridden post() which I have not. So I have no idea why this is happening and how to solve it. Would appreciate any help.

Sum values from child models using nested Subquery and annotaions in Django Viewset
I'm trying to calculate the total price of a Recipe. To optimize DB queries I'm trying to use Django's ORM capabilities to perform the fewest requests. My models.py is like this: class BaseRecipe(models.Model): title = models.CharField(_('Base recipe title'), max_length=255, user = models.ForeignKey(User, null=True, on_delete=models.CASCADE, related_name='user_base_recipes') class Meta: ordering = ['title'] def __str__(self): return self.title class IngredientBaseRecipe(models.Model): base_recipe = models.ForeignKey(BaseRecipe, on_delete=models.CASCADE, related_name='ingredients') name = models.CharField(_('Name'), max_length=255) products = models.ManyToManyField(Product) quantity = models.FloatField(_('Quantity'), default=0.0) class Meta: ordering = ['-id'] def __str__(self): return self.name class Product(models.Model): name = models.CharField(_('Name'), max_length=255, help_text=_('Product name')) price = models.FloatField(_('Sale price'), default=0) class Meta: ordering = ['name', ] indexes = [models.Index(fields=['name',]), ] Then in my Viewset I'm trying to get the BaseRecipes queryset with an annotated field that shows the sum of the ingredients prices. I get to the point to obtain the ingredients price, but I'm stucked trying to sum them in the BaseRecipe query set: min_price = ( Product.objects.filter(name=OuterRef('name')) .annotate(min_price=Min('price')) .values('min_price') ) ingredients_price = ( IngredientBaseRecipe.objects .filter(base_recipe=OuterRef('id')) .annotate(price=Subquery(min_price)) .order_by() .annotate(total=Sum(F('price') * F('quantity'))) .values('total') ) queryset = BaseRecipe.objects.filter(user=self.request.user) \ .annotate(cost=Sum(ingredients_price)) return queryset Thanks a lot for your help! -
How does Django map the urls when there is ambiguity
I have the url patterns in my project urls.py url(r'^', include('app.urls')), url(r'^api/app/', include('app.url.router_urls')), and in the app.urls i have something like url(r'^api/app/user$', views.user_validator), and in the app.url.router_urls i have something like url('^v1/', include('app.url.app_v1.urls')) I have a question around these. so when the request is BASE_URL/api/app/{user} which url will be mapped to this? and how about BASE_URL/api/app/v1/ which url will be mapped. this will map first with ^ right and will use the app.urls for both? thanks -

Update data with image in Django through Axios
I am trying to update the data with a field image. I followed this link https://stackoverflow.com/a/28036805/15320798 to successfully upload an image. But when I try to update the data without changing the image field, it throws the error Upload a valid image. The file you uploaded was either not an image or a corrupted image. The scenario is that I have to change other fields and keep the image field the same. Example Request Payload: { "name":"John" "age":18, "image:""http://localhost:8000/media/9154fb95-0f1.jpg" } and this is how I send the data from vue axios .put(url, data) .then((response) => { console.log("success") }) serializers.py class UserSerializer(serializers.ModelSerializer): image = Base64ImageField(max_length=None,use_url=True,) # this is from the link above class Meta: model = User fields = ( "name", "age", "image" ) Is there any way I can execute this? -

What's the reason of my drop down class doesn't iterate?
this is base html codes. I sent categories, products in views.py to base.html. they are defined in models.py as Category, Product as OnetoOne Relationship. <div class="btn-group"> {% for category in categories %} <button type="button" class="btn" id="BASE_SECOND_ADAPTERS"> <a href="{{category.get_absolute_url}}" class="btn" id="C_TITLE">{{category.title}}</a> </button> <button type="button"> <span class="sr-only">Toggle Dropdown</span> <div> {% for product in category.product_set.all %} <div class="button"> <a href="{{product.get_absolute_url}}">{{product.name}}</a> </div> {% endfor %} </div> </button> {% endfor %} </div> this is the problem. first, the href in products iteration doesn't work. When i delete the data-toggle="dropdown" it works. 1Cat - 1-2Pro, 1-1Pro 2Cat - 2Pro 3Cat - 3Pro But Iteration ended before 2Category. If i delete the drop down class, It work. How can i solve it? -

How do I use Django's CheckConstraint to restrict a variable at the database level?
I'm trying to write an application that receives incoming tickets for a small IT department. Currently these tickets come in through a webhook so I want to restrict what comes in at the database level. I want to restrict the status variable of the ticket to the choices described in the ticketStatus model but the database is still accepting values outside these choices. I've experimented with using CheckConstraint but can't quite get it to work. My code is as follows: class ticketStatus(models.TextChoices): Active = "Active" Acknowledged = "Acknowledged" Resolved = "Resolved" Unresolved = "Unresolved" class Ticket(models.Model): dateTimeRecieved = models.DateTimeField(default=timezone.now) deviceId = models.ForeignKey(Device, related_name="Device", on_delete=models.DO_NOTHING) issue = models.CharField(max_length=100) status = models.CharField(max_length=20, default="Active") def __str__(self): return f"Device {self.deviceId}: {self.issue}" class Meta: constraints = [ models.CheckConstraint( models.Q(status__in=ticketStatus.values) ), ] At the moment, I'm getting this error when I attempt the migration: TypeError: __init__() takes 1 positional argument but 2 were given I believe this is associated with models.Q(status__in=ticketStatus.values) I'm currently using Django version 3.2.4 -

Cant display values in Django templates
I'm new to Django, I am trying to display a single book in a template(show.html) like <h1 class="text-center text-4xl py-5">{{book.title}}</h1> <img src="{{ book.thumbnailUrl }}" alt="" class="w-56"> <p>{{book.shortDescription}}</p> <p>{{book.longDescription}}</p> The view rendering the template is (trying to render a single book from JSON file by id) def show(request, id): with open('bookstore/books.json') as file: book_dict = json.load(file)['books'] book = [book for book in book_dict if book['id'] == id] context = {'book': book} return render(request, 'books/show.html', context) When debugging by printing {{ book }} in show.html it results in a list with a dictionary of a book [{'id': 1, 'title': 'Unlocking Android', 'isbn': '1933988673', 'pageCount': 416, 'publishedDate': {'$date': '2009-04-01T00:00:00.000-0700'},...}] Hence I think that's the problem when I try to access the title using dict syntax like({{ book. title}} ) But I can't seem to find a workaround. -
Django saves time data in UTC despite using localtime
In my settings file, I have : LANGUAGE_CODE = 'en-us' TIME_ZONE = 'Asia/Kolkata' USE_I18N = True USE_L10N = True USE_TZ = True in my views: import datetime def some_function: print(datetime.datetime.now()) << prints my local time However, when using the same datetime.datetime.now() to store the current localtime into a DateTimeField, it gets converted in UTC. I understand that its a good things that it all gets converted into UTC when being stored into Database. Objective being, it will be easier for us to convert UTC to any localtime when we are using these stored values and rendering to the user. This last step, of converting UTC time to localtime, which I assume that django should do by default, is where I'm stuck at. the datetime values are still being rendered as UTC instead of my localtime despite using USE_TZ = True in my settings. -

How to query a Django queryset through a foreign key on another model?

I can query for all the files first and then loop through them and add the cases to a list. Is that the best way to go about this problem? Thanks in advance for any help. -
AttributeError: 'User_Profile' object has no attribute '__name__'
Hello I hope everyone is having a good day, my goal is to get my forms.py to send the email form content to a different model into my Django database, from the default User model in Django to my custom-made User_Profile model. I believe if I can fix the error above that, my goal will be accomplished. In my forms.py file, I am importing a class from the model.py then using the function again in the forms.py, which is what is causing the error. I did my research on __ name__ with classes, and from what I understood, it has to do with using the same class two different times and it doesn't know which one to run or something. If someone could explain __name __ with classes better and help me fix the error, I would much much appreciate that. Here is my models.py class User_Profile(models.Model): user = models.OneToOneField(User, null = True, blank = True, on_delete = models.CASCADE) name = models.CharField(max_length = 200, null = True) phone = models.CharField(max_length = 200, null = True) email = models.CharField(max_length = 200, null = True) profile_image = models.ImageField(null = True, blank = True) data_created = models.DateTimeField(auto_now_add = True, null = True) def … -
How can i update the field of a model from another model field in django?
I have two models. DepartmentGoal with a field 'scores' and Task also with a field 'scores' and a foreign departmentgoal. What I want is; If I allocate scores to DepartmentGoal, scores allocated to Task should subtract from scores of DepartmentGoal which means Any number of instances of scores of Task when summed up should be equal to score of a single instance of DepartmentGoal. I just need a clue on how to implement this. This are the models class DepartmentGoal(models.Model): name = models.TextField(max_length=150, null=True) score = models.IntegerField(null=True, blank=True) created_at = models.DateTimeField(auto_now_add=True, null=True) updated_at = models.DateTimeField(auto_now=True, null=True) def __str__(self): return self.name class Task(models.Model): name = models.CharField(max_length=300, null=True) departmentgoal = models.ForeignKey(DepartmentGoal, on_delete=models.CASCADE, related_name='departgoal', null=True, blank=True) score = models.IntegerField(null=True, blank=True) created_at = models.DateTimeField(auto_now_add=True, null=True) updated_at = models.DateTimeField(auto_now=True, null=True) def __str__(self): return self.name Here the the forms class DepartmentGoalForm(ModelForm): class Meta: model = DepartmentGoal fields = ( ('name'), ('score'), ) class TaskForm(ModelForm): class Meta: model = Task fields = [ 'departmentgoal', 'name', 'score', ]
