Annotate based on related field, with filters
class IncomeStream(models.Model): product = models.ForeignKey(Product, related_name="income_streams") from_date = models.DateTimeField(blank=True, null=True) to_date = models.DateTimeField(blank=True, null=True) value = MoneyField(max_digits=14, decimal_places=2, default_currency='USD') class Product(models.Model): ... class Sale(models.Model): product = models.ForeignKey(Product, related_name="sales") created_at = models.DateTimeField(auto_now_add=True) ... With the above model, suppose I want to add a value to some Sales using .annotate. This value is called cpa (cost per action): cpa is the value of the IncomeStream whose from_date and to_date include the Sale created_at in their range. Furthermore, from_date and to_date are both nullable, in which case we assume they mean infinity. For example: <IncomeStream: from 2021-10-10 to NULL, value 10$, product TEST> <IncomeStream: from NULL to 2021-10-09, value 5$, product TEST> <Sale: product TEST, created_at 2019-01-01, [cpa should be 5$]> <Sale: product TEST, created_at 2021-11-01, [cpa should be 10$]> My question is: is it possible to write all these conditions using only the Django ORM and annotate? If yes, how? I know F objects can traverse relationships like this: Sale.objects.annotate(cpa=F('offer__income_streams__value')) But then where exactly can I write all the logic to determine which specific income_stream it should pick the value from? -
Why my codes showing during during runtime? (Django)
I just wanna ask what's wrong with my codes? <div class="form-row"> <div class="form-group col-md-6"> <label><b>Lot Area: </b></label> <input type="text" id='lot_area' class="form-control" oninput="amount_calculate()" value="{{form.c_lot_area}}"> </div> </div> I am using Django. When I run it, the codes also display. It always shows the double quotes and the right arrow during runtime. -
Celery AttributeError : 'download_all' object has no attribute 'location'
I want to create a progress bar for my project. I have a class and this class has some functions. Especially, one of them takes a long time (def download_all) and this is my main reason for wanting to create a progress bar. I successfully set up celery, celery-progress, etc. and they work all fine. My problem is this: I want to integrate the progress bar to download_all function. I It gives an error: AttributeError: 'download_all' object has no attribute 'location' I am sure that this error is because of the celery task because when I run it without celery, it works.

width not correct in when using d-flex in Bootstrap 5.0
I have a base.html file that I am using as a template in my Django project. I used d-flex to create top nav and sidebar but I am struggling to set up width and height on each website to 100%. When running it as a static page everything is ok but when I try to run it in Django then the result is like this: As you can see the width and height are not 100% but they are adjusting somehow to the content.

Django HyperlinkedModelSerializer on a table that has a field marked as pk + fk
I have this table which has a field marked as a primary key, when it also is a foreign key. Isn't ideal, but need to deal with this at the moment. class Profile(models.Model): class Meta: verbose_name_plural = "Profiles" member = models.OneToOneField( Member, on_delete=models.CASCADE, primary_key=True, ) ... Now I have a django-rest-framework serializer for the Member and Profile models, that looks like this, class MemberSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Member fields = ('id', 'role_id', 'user_id') class MemberProfileSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Profile fields = ['member_id','bio','address','mobile'] The question I have is that, when I have the 'member_id' extracted from MemberProfileSerializer, it lists down the id correctly (this is the id that is pk for Profile, and is also fk to the Member table) But if I need to extract more information from the Member model, and to do that, if I add a reference to the MemberSerializer, I get back an empty object in the results! class MemberProfileSerializer(serializers.HyperlinkedModelSerializer): member_id = MemberSerializer() class Meta: model = Profile fields = ['member_id','bio','address','mobile'] Any suggestions on why this could be happening! -

How add claims to SAML IDP metadata
I built the SSO integration project, I will be an IDP identity provider and our third party will be an SP services provider.

But I have a question how I can add claims to this generated metadata so that helps our SP use it? here is the generated metadata file: <ns0:EntityDescriptor

If I set upload_to like this , document = models.FileField(upload_to='/var/www/html/myproj_mat/') It says to use 'relative path' These are error stack trace. response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/home/ubuntu/anaconda3/envs/aiwave/lib/python3.8/site-packages/django/views/decorators/csrf.py", line 54, in wrapped_view return view_func(*args, **kwargs) File "/home/ubuntu/anaconda3/envs/aiwave/lib/python3.8/site-packages/django/views/generic/base.py", line 70, in view return self.dispatch(request, *args, **kwargs) File "/home/ubuntu/anaconda3/envs/aiwave/lib/python3.8/site-packages/rest_framework/views.py", line 509, in dispatch response = self.handle_exception(exc) File "/home/ubuntu/anaconda3/envs/aiwave/lib/python3.8/site-packages/rest_framework/views.py", line 469, in handle_exception self.raise_uncaught_exception(exc) File "/home/ubuntu/anaconda3/envs/aiwave/lib/python3.8/site-packages/rest_framework/views.py", line 480, in raise_uncaught_exception raise exc File "/home/ubuntu/anaconda3/envs/aiwave/lib/python3.8/site-packages/rest_framework/views.py", line 506, in dispatch response = handler(request, *args, **kwargs) File "/var/www/html/aicomposer/current/defapp/views.py", line 350, in post entry.save() File "/home/ubuntu/anaconda3/envs/aiwave/lib/python3.8/site-packages/django/db/models/base.py", line 726, in save self.save_base(using=using, force_insert=force_insert, File "/home/ubuntu/anaconda3/envs/aiwave/lib/python3.8/site-packages/django/db/models/base.py", line 763, in save_base updated = self._save_table( File "/home/ubuntu/anaconda3/envs/aiwave/lib/python3.8/site-packages/django/db/models/base.py", line 868, in _save_table results = self._do_insert(cls._base_manager, using, fields, returning_fields, raw) File "/home/ubuntu/anaconda3/envs/aiwave/lib/python3.8/site-packages/django/db/models/base.py", line 906, in _do_insert return manager._insert( File "/home/ubuntu/anaconda3/envs/aiwave/lib/python3.8/site-packages/django/db/models/manager.py", line 85, in manager_method return getattr(self.get_queryset(), name)(*args, **kwargs) File "/home/ubuntu/anaconda3/envs/aiwave/lib/python3.8/site-packages/django/db/models/query.py", line 1270, … -

How to manage a form with many-to-many intermediate table fields and class-based views?
I would like to be able to edit an article directly via the web page where it is displayed. For this I use the UpdateView. My "News" model has a many to many relationship with my "User" model. The intermediate model is called "NewsUpdate" and it has 2 additional fields (update_date and update_reason). I can display and run the edit form of my "News" model, but I can't add the "update_reason" field and validate it. Is it possible to do this with the generic views? Thank you in advance! models : class News(models.Model): ... image = models.ImageField(upload_to='contents', null=True, blank=True) uuid = models.UUIDField(default=uuid.uuid4, unique=True, verbose_name='UUID') author = models.ForeignKey(AUTH_USER_MODEL, on_delete=models.CASCADE, verbose_name='Auteur', related_name='create_news') news_update_user = models.ManyToManyField(AUTH_USER_MODEL, through='contents.NewsUpdate', related_name='news_update_user') news_delete_user = models.ManyToManyField(AUTH_USER_MODEL, through='contents.NewsDelete', related_name='news_delete_user') class NewsUpdate(models.Model): news = models.ForeignKey(News, on_delete=models.CASCADE, related_name='updated_news') updater = models.ForeignKey(AUTH_USER_MODEL, on_delete=models.CASCADE, verbose_name='Auteur', related_name='news_updater') update_date = models.DateTimeField(auto_now=True, null=True, verbose_name='Modification le') update_reason = models.CharField(max_length=250, verbose_name='Raison de la modification') class Meta: unique_together = ('news', 'updater') class User(AbstractUser): first_name = models.CharField( max_length=30, blank=True, null=True, verbose_name='Prénom' ) last_name = models.CharField( max_length=30, blank=True, null=True, verbose_name='Nom' ) ...
