IndexError on Django/MySQL after ordery_by an union queryset
I am using Django on ubuntu ec2 and MySQL on RDS. I try to obtain 3 random objects satisfying condition 1 (is_shoes=True, is_bag = False) and 2 random objects from the same model with different condition (is_shoes=True, is_bag = True) and union it in a random order.

I want to display all the created department in one view using a for loop and update all the record at once. the problem is it is taking only the first record and updating all the record with the value entered at the first field I tried using .getlist() but still taking only the first record. how to update each record with reference to its id and if the field is empty keep that record untouched.

Is partial form a good practice in Django?
I'm new in Django and I try to find out if saving partial forms is a good practice or not. For example, I have Poll App and Candidate model with four fields: name, surname, targets andbiography. And I have a form where I have to fill all these fields. But if user only finished fill name, surname and targets, but even din't start filling biography field, how can I save his draft to user can finish it later and don't make any security mess? I will be happy to see all ideas. -
How to save model in Django with unique but null fields
How can I save a model that should be unique but also allowed to be null in Django. For instance I have the following model... class PetOwner(models.Model): """Model representing a pet owner.""" user = models.OneToOneField(User, on_delete=models.CASCADE) first_name = models.CharField(max_length=50, help_text="Enter owner's first name") last_name = models.CharField(max_length=50, help_text="Enter owner's last name") email = models.EmailField( max_length=50, blank=True, unique=True, help_text="Enter owner's email" ) phone_number = models.CharField( max_length=15, blank=True, unique=True, help_text="Enter owner's phone number" ) address = models.ForeignKey( "Address", on_delete=models.SET_NULL, null=True, blank=True ) I want my app to work the following way. A PetOwner can sign up but when they do they initially only sign up with a username, password, a confirmation password, and first_name, and last_name. I want my to have a profile page which will allow for updating the PetOwner to include their phone_number but I do not necessarily want to make this a requirement. I decided that I'd make phone_number field null=True and blank=True but as soon as I register a second user I get a django.db.utils.IntegrityError: UNIQUE constraint failed: app_petowner.phone_number error. I believe it is because when I register a user for some reason instead of phone_number being None even when I did not actually add a phone number at … -
how to upload multiple images properly
I have a simple model which has four different fileFields for uploading different files and images. this is my models: class DocumentInfo(models.Model): id = models.AutoField(primary_key=True) certificate = models.FileField(upload_to="documents", null=True) id_card = models.FileField(upload_to="documents", null=True) service_certificate = models.FileField(upload_to="documents", null=True) educational_certificate = models.FileField(upload_to="documents", null=True) users need to simply upload some images in four individual fields so, I created a simple form and passed it to views like this: class DocumentForm(forms.ModelForm): class Meta: model = DocumentInfo fields = ['certificate','id_card','service_certificate','educational_certificate'] views.py: def document_info(request): if request.method == 'POST': form = DocumentForm(request.POST, request.FILES) if form.is_valid(): form.instance.user = request.user form.save() return redirect('document') if 'delete' in request.GET: return delete_item(DocumentInfo, request.GET['id']) else: form = DocumentForm() documents = DocumentInfo.objects.filter(user=request.user) context = { 'form': form, 'documents': documents, } return render(request, 'reg/documents.html', context) it works just fine at first but I cant reupload anything! the uploaded image neither gets saved the second time around nor deleted. what am I doing wrong? -

How to properly design django related model

This how I designed the model: from django.db import models # Create your models here. from django.contrib.auth.models import AbstractUser class Event_type(models.Model): """ Event_type is like a category model for patient, datebase relationship is one to many """ name = models.CharField(max_length=40) class Meta: verbose_name = "event_type" verbose_name_plural = verbose_name def __str__(self): return self.name class Patient(models.Model): patient_id = models.AutoField(unique=True, primary_key=True) # patient identification patient_name = models.CharField(max_length=30, blank=True, null=True, verbose_name='patient_name') event_type = models.ForeignKey(Event_type, on_delete=models.CASCADE, blank=True, verbose_name='event type') event_value = models.PositiveIntegerField(default=0, verbose_name='even value', blank=True) event_unit = models.CharField(max_length=100, blank=True, verbose_name='event unit') event_time = models.DateTimeField(auto_now=True, verbose_name='event time') class Meta: verbose_name = 'Patient' verbose_name_plural = verbose_name ordering = ['-patient_id'] def __str__(self): return self.patient_name However I guess while loading the data into database I may have the ununique error. Any better design ? Any friend can help? -
Django Session Form (save form temporarily)
I have created a page for review form. All users can fill out the form, but only logged in users can submit the form. If users is not logged in, they will be redirected to the login page. After they login, they will be redirected to the profile page. So the flow will be like this : User fills out the form > click the submit > redirected to login page > user login and redirected to profile page (at the same time, the form they have filled in is automatically saved) I want the form they have filled in automatically saved after they login. How to do that? My idea is to create a session that saves the form temporarily, then save to database after they login. But I'm confused how to write the code Can anyone explain a bit what a django session is like? and how to write code to handle this problem? -

Whether I run django-admin check or anything using python manage.py I get the below error: Traceback (most recent call last): File "/home/bitnami/djangoenv/lib/python3.8/site-packages/django/apps/config.py", line 244, in create app_module = import_module(app_name) File "/opt/bitnami/python/lib/python3.8/importlib/__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1014, in _gcd_import File "<frozen importlib._bootstrap>", line 991, in _find_and_load File "<frozen importlib._bootstrap>", line 973, in _find_and_load_unlocked ModuleNotFoundError: No module named 'akita_app' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/home/bitnami/djangoenv/bin/django-admin", line 8, in <module> sys.exit(execute_from_command_line()) File "/home/bitnami/djangoenv/lib/python3.8/site-packages/django/core/management/__init__.py", line 419, in execute_from_command_line utility.execute() File "/home/bitnami/djangoenv/lib/python3.8/site-packages/django/core/management/__init__.py", line 395, in execute django.setup() File "/home/bitnami/djangoenv/lib/python3.8/site-packages/django/__init__.py", line 24, in setup apps.populate(settings.INSTALLED_APPS) File "/home/bitnami/djangoenv/lib/python3.8/site-packages/django/apps/registry.py", line 91, in populate app_config = AppConfig.create(entry) File "/home/bitnami/djangoenv/lib/python3.8/site-packages/django/apps/config.py", line 246, in create raise ImproperlyConfigured( django.core.exceptions.ImproperlyConfigured: Cannot import 'akita_app'.

Can I use ABC and Django Abstract classes together in Python?
I have a django abstract class: class AbstractModel(models.Model): date_added = models.DateField(auto_now_add=True) class Meta: abstract = True I want my concrete classes (Django Models) to subclass this abstract class, but I also want to make sure that all my concrete classes always implement very specific methods using abc. I tried doing this: class AbstractBaseClass(AbstractModel, metaclass=abc.ABCMeta): @abstractmethod def important_method(self): pass class MyDjangoModel(AbstractBaseClass): ... And I tried: class AbstractBaseClass(ABC): @abstractmethod def important_method(self): pass class MyDjangoModel(AbstractModel, AbstractBaseClass): Neither worked. They both say: TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases Is there a way to do this, or is this impossible? -
Django App Deploy on elastic beanstalk WSGI path issue
I am deploying the app then it gets severed health and 502 gateaway returns on browser. I checked out the logs lines I found these.

Password Lock after Multiple Login Attempts for Django + simplejwt
I'm building Django app and implemented login function with django restframework simplejwt. Now trying to add function to lock out users after multiple wrong login attempts. Many people suggest django-axes package, but it only works with Django's default authentication backend, not with simplejwt's views. Any existing python packages help for this? Otherwise, how do you implement such a function with simplejwt? -
Django: No random letters in same name file uploaded
This is my code to let my user upload files, when more then one file is uploaded with the same condition by default random letters are added to the file name to avoid duplicate, is it possible to have the quantity number of file uploaded instead? so instead of having randomfilename randomfilename_jlCtWGb randomfilename_aOMtTeb have this randomfilename_1 randomfilename_2 randomfilename_3 Code: models.py def user_directory_path(instance, filename): filename = "word_file_%s.%s" % (instance.option, extension) return 'word_folder/{0}/{1}'.format(instance.option, filename) class Document(models.Model): option_choice = [ ('1', 'Option One'), ('2', 'Option Two') ] user = models.ForeignKey(UserInformation, on_delete=models.CASCADE) option = models.CharField(max_length=250, choices=option_choice, blank=True, null=True) original_filename = models.CharField(max_length=250, blank=True, null=True) docfile = models.FileField(upload_to=user_directory_path) def __str__(self): return word_db_' + self.option views.py @login_required def upload_file(request): if request.method == 'POST': form = DocumentForm(request.POST, request.FILES) uploaded_file= request.FILES if form.is_valid(): form.instance.user = request.user.userinformation form.instance.original_filename = uploaded_file['docfile'].name form.save() return redirect('upload_file') else: message = 'The form is not valid.

Encoding and decoding a base64 image in django
I have a django project in which I encode an image to Base64 via a serializer with the Base64ImageField field method There are no problems, but there is no way to get the image back:( In order not to get a 404 error in the serializer, I use SerializerMethodField and return STATIC_ROOT + obj.image.name . In this case, the code 200 is returned, but the picture is not displayed. I tried to decode through base64.b64decode(obj.image.encode('UTF-8')) and other methods of decoding and processing base64 drawings, but no one of them looks out the necessary code in the file. My decode serializer code to read: class DecodeSerializer(ModelSerializer): image = SerializerMethodField() class Meta: fields = "__all__" model = MyModel def get_image(self, obj): return STATIC_ROOT + obj.image.name My encode serializer: class EncodeSerializer(RecipesSerializer): image = Base64ImageField(max_length=None, use_url=True) class Meta: fields = "__all__" model = MyModel
