Combining Context Values (filter and queryset) - Python - Django Views - Filter and User
I need to combine two context values in my views.py for my python Django website. One is a filter at the top of the screen that filter all displayed data below and it looks like this... context['filter'] = Sheet_Building_Filter(request.GET, queryset=Sheet_Building.objects.all()) The other is not a page filter but it filters and returns all the data that is from the user that is currently logged in and it looks like... context['user'] = Sheet_Building.objects.filter(user=request.user) I need to combine these to loop through both of them in HTML at the same time. I thought something like this would work but it didn't... context['user_and_filter'] = Sheet_Building_Filter(request.GET, queryset=Sheet_Building.objects.filter(user=request.user)) This just displays the data and doesn't show the filter itself. I'm not sure if the filter works but isn't displaying the fields to filter by or if it is just not working at all. Im not sure why and I can't find any information of a filter and user data is combined into one value. I need it combined because I can't do a nested for-loop in HTML. Code below. Thanks! views.py def listdata_building(request): sheet = Sheet_Building.objects.all() context = {"sheet": sheet} context['user_and_filter'] = Sheet_Building_Filter(request.GET, queryset=Sheet_Building.objects.filter(user=request.user)) context['user'] = Sheet_Building.objects.filter(user=request.user) return render(request, 'sheets/individual/list_data_building.html', context) models.py class Sheet_Building(models.Model): user … -
Is it a good practice to create several one2one fields using signals during user registration? Is there a better way?
Hey guys I have six models that have OneToOne relation with account model and are being created with signals at the time when a user register on the website? Is this a bad practice when there are more number of users? Is there a better way to do it? Should I use celery or some other method to create those models which are of less significance (comparatively) ? Please do let me know. Thanks in advance. -
Add Profile picture to Django Custom User model(AbstractUser)
I have used a custom user model to overwrite username with email-id. Now I want to add an extra field that profiles pictures. I tried extending the model in models.py with the OnetoOne relationship. It works but as I am passing forms to update and create views (Class-based views) to update and create. is there any way to add a profile picture field without creating a model with the OnetoOne relationship? models.py class UserManager(BaseUserManager): """Define a model manager for User model with no username field.""" use_in_migrations = True def _create_user(self, email,profilepicture, password, **extra_fields): """Create and save a User with the given email and password.""" if not email: raise ValueError('The given email must be set') email = self.normalize_email(email) user = self.model(email=email, **extra_fields) user.set_password(password) user.save(using=self._db) return user def create_user(self, email, password=None, **extra_fields): """Create and save a regular User with the given email and password.""" extra_fields.setdefault('is_staff', False) extra_fields.setdefault('is_superuser', False) return self._create_user(email, password, **extra_fields) def create_superuser(self, email, password, **extra_fields): """Create and save a SuperUser with the given email and password.""" extra_fields.setdefault('is_staff', True) extra_fields.setdefault('is_superuser', True) if extra_fields.get('is_staff') is not True: raise ValueError('Superuser must have is_staff=True.') if extra_fields.get('is_superuser') is not True: raise ValueError('Superuser must have is_superuser=True.') return self._create_user(email, password, **extra_fields) class User(AbstractUser): """User model.""" username = … -
Crypto module and Encryption method not working
Basically, my question is divided into two problems, first of all, I am having this problem when I try running this code [code below] and get an error, like this: ImportError Traceback (most recent call last) <ipython-input-3-3d0c04910b61> in <module> 1 import hashlib ----> 2 from crypto import Random 3 from crypto.Cipher import AES 4 from base64 import b64encode, b64decode 5 ImportError: cannot import name 'Random' from 'crypto' (C:\Users\Ahmad\anaconda3\lib\site-packages\crypto\__init__.py) The second problem is when I enter text, i.e: "My data is here" I got the encrypted text as : "GIdd+zxj8m0nMeh7wmZJ+Q==" but reversing the process in decryption it outputs a different text, to validate the process I am using and checking through https://aesencryption.net/ as reference in my work.

How do I make a track report from my Django models in a way that the report also has its auto-incremented primary key?
I have 3 models: class Student(models.Model): roll_number=models.IntegerField(primarykey=True) name=models.CharField(max_length=50) email=models.EmailField(max_length=60) city=models.CharField(max_length=20) class Course(models.Model): roll_number=ForeignKey(Student, on_delete=CASCADE) course=ForeignKey(CourseChoices, on_delete=CASCADE) class Fee(models.Model): roll_number=ForeignKey(Student, on_delete=CASCADE) amount_to_be_paid=models.DecimalField(max_digits=7, decimal_places=2, default=0) discount=models.DecimalField(max_digits=5, decimal_places=2, default=0) Final_amount_to_be_paid=models.DecimalField(max_digits=5, decimal_places=2, default=0) Amount_received=models.DecimalField(max_digits=5, decimal_places=2, default=0) Balance=models.DecimalField(max_digits=5, decimal_places=2, default=0) batch=models.CharField(validators=[batch_pattern]) Now, whatever data these tables hold, I want to display them together as: I want each and every transaction to be tracked by a separate track id. The track id should be auto-incrementing, unique key. How do I achieve this? I tried creating one more model while applying multiple inheritance on it but It clearly couldn't work. That way, the user would have to enter the data in the table created by the last model where all the fields would be available to fill but the scenario cannot allow this as each forms would be filled on separate days, not at once. So the complete information are to be entered separately, so forms are divided. But I want them together to track each transaction with a track ID. I'm a beginner and just trying stuffs here but I'm constantly failing since almost a week now. Any suggestions, please!! Thanks for your help! -

How can I model a database view in Django if it doesn't have a primary key?
I have a database view that relates 2 companies by foreign keys like so: DB company_view: company1_id FK to Company, company2_id FK to Company, some_description text I try model in Django as unmanaged like so: class CompanyView(models.Model): company1 = models.ForeignKey(Company, related_name='company1_id', parent_link=True) company2 = models.ForeignKey(Company, related_name='company2_id', parent_link=True) class Meta: managed = False db_table = 'company_view' But it throws exception like: psycopg2.errors.UndefinedColumn: column company_view.id does not exist It doesn't make sense to have a primary id key, so is there any way around this?

Python: Calculate time between current time and last login. (Automated Communication)
I'm trying to make a celery task that would send a basic reminder to our users. So in our automated communication project, we have these tasks: As you can see there are few actions that are different. So for now I have created a logic that fetches all the users from the DB and then continues by checking the time difference. But for now, I only have set-up for 2 hours or more. How should I use it correctly? I do not want to re-write each if statement because it's bad practice. How should I make it clear and reduce the system load? @app.task def check_registered_users(): from apps.users.models import User from apps.notifications.models import AutomatedCommunicationNotifications day_start = datetime.utcnow().date() day_end = day_start + timedelta(days=1) users = User.objects.filter(is_active=True, date_joined__range=(day_start, day_end)) users_that_received_notification = AutomatedCommunicationNotifications.objects.all().values('user__id') excluded_users = users.exclude(id__in=users_that_received_notification) for user in excluded_users: if user.last_login < user.last_login + timedelta(hours=2): # Sign-up uncompleted Push notification 2 hours after last login template = SiteConfiguration.get_solo().automated_comms_signup_uncompleted send_plain_email_task( email=user.email, subject=template.subject, html_message=template.content, from_email=f'{settings.EMAIL_FROM_PREFIX} <{settings.DEFAULT_FROM_EMAIL}>', ) -

How is PUT request handled in Django REST Framework?
I need to clarify how DRF works. Imagine there's a Django REST Framework application that manages two ressources: departments and employees: class Department(models): name = models.CharField(primary_key=True) class Employee(models): name = models.CharField() dept = models.ManyToManyField() with serializers: class DepartmentSerializer(serializers.ModelSerializer): class Meta: model = Department fields = ('name', ) class EmployeeSerializer(serializers.ModelSerializer): dept = DepartmentSerializer class Meta: model = Employee fields = ('name', 'dept', ) Requesting (GET /employees/1) an employee returns the department as a nested object, which is good. What does DRF do, when I send PUT /employees/1 { "department": "sales" } Which part of the program does this request go through? I would assume First using dispatching a view is selected In the update Method (if overwritten) of the view, I can assign a serializer The request and Primary Key of the target are available through self.request and pk of the method handler What I end up doing now is to write a bloated update method, which kind of does not feel the way it should be where I check for every attribute if it is in the request and if yes than update it. def update(self, request, pk=None): employee = Employee.objects.get(pk=pk) if self.request.data.get("name"): employee.name = self.request.data.get("name") if self.request.data.get("dept"): employee.dept.add(self.request.data.get("dept") employee.save() … -
django-autocomplete-light template not rendering autocomplete widget

Password is displayed as text in the admin panel (not hashed)
There is a CustomUser model inherited from AbstractUser. When registering a model in the admin panel, the password is displayed as text, that is, the type of this field is text, not password. I know that this problem can be solved if, together with the model, the ModelAdmin class is registered, in my case it will be CustomUserAdmin inherited from UserAdmin from django.contrib.auth.admin, and the password will be displayed correctly, but then the fields from CustomUser will not be displayed (as if the CustomUser model is registered, but only the fields of the User model will be displayed, when using a class inherited from the above-mentioned UserAdmin). What to do with this, please tell me! -

Annotating single model instance (instead of queryset) in django
So, I have a Post model which contains PostVotes from users class Post(models.Model): voters = models.ManyToManyField(User, through="PostVote") #other stuff and the post vote can have a state of either "upvote" or "downvote" (I know I should be using enums or a bool for this before I start receiving those comments) and in many cases I need to count the total score of the object for the frontend. When I have the posts in a queryset, the following solution is working well: posts = Post.objects.all().annotate(vote=models.Sum( models.Case( models.When(postvote__state="upvote", then=1), models.When(postvote__state="downvote", then=-1), default=0, output_field=models.IntegerField() ) )) However, there are many cases where I want to do a similar thing but instead of a queryset I have just a single instance. How do I do this? Trying the above solution gives 'Post' object has no attribute 'annotate' -

Issues with JSONField order_by querying fields with punctuations in the name

I am begginer who needs some help. I made custom token authentication, where token was stored in localStorage with expiration date, then to know if user is logged I just check if token exists - simply as that.

After loggin in with form (username, password fields) I can not figure how to check if user has logged in or redirect him from login page.

Combine one-to-one and many-to-many (django)
I have a model named "db_connector" and another one "project_site". A "project_site" can have many to many relation with "db-connector". But the "project_site" should have one default db-connector. What is the best design-pattern for this? Can I combine many to many and one to one like this: Many to many relation for alternative connectors linked to a project_site and one to one for the default connector linked to a project_site?
