Django App - allowing users to save their favorite posts to their profile for quick access
I'm working on a Django app that is essentially a database for different gym workouts. It allows users to search for workouts, and I anticipate that as scale increases, it would be annoying to keep searching for the same workout the user wants to learn about. Is there functionality in Django to let the user 'save' a certain workout so it appears on their profile page, almost like a playlist of sorts? -

SQLAlchemy: limit select depth for self referencing table
I have two SQLAlchemy models: Comment and User, defined as following: Comment class Comment(Base): __tablename__ = 'comment' id = Column(Integer, primary_key=True,autoincrement=True , index=True) .... owner_id = Column(String, ForeignKey("user.id"), nullable=False) item_id = Column(Integer, ForeignKey("item.id"), nullable=False) original_comment_id = Column(Integer, ForeignKey("comment.id"), nullable=True) #relationship owner = relationship("User", back_populates="comments") item = relationship("Item", back_populates="comments") replies = relationship("Comment", backref=backref('parent', remote_side=[id])) User class User(Base): __tablename__ = 'user' id = Column(String, primary_key=True, index=True ) .... comments = relationship("Comment", back_populates="owner") As shown above, each comment can be a reply to another comment. I want to get a list of all comments for a given item, and each comment should contain its immediate parent only, if it has one. To achieve that, I'm using the following code comments = db.query(Comment).filter(Comment.item_id == item_id)\ .options( joinedload(Comment.owner).options(load_only("display_name")), joinedload(Comment.parent).options(joinedload(Comment.owner).options(load_only("display_name")))\ ) But it's not giving me just the immediate parent, but grandparents too. How can I limit the depth to immediate parents only ? -

Override a save function to always update or create Django
I want to override the function for saving the profile inside the actual model. Here is my attempt so far: class Profile(models.Model): # others def save(self, *args, **kwargs): # Object is a new profile if email does not exist if not Profile.objects.filter(email = self.email).exists(): # save return super().save(*args, **kwargs) #object is an existing profile else: # update return super().update(*args, **kwargs) Simply update if its on the db. I'm doing this because I can't do the usual update_or_create from ImportExportModelAdmin. Any answer or link is appreciated. -

How to store a dictionary in a Django database model's field?

How to change django-phonenumber-field error messages
I am using django-phonenumber-field. Everyone who uses this app probably knows that any prefix has the same example "Enter a valid phone number (e.g. +12125552368)." Enter a valid phone number (e.g. +12125552368). So, I don't like it and I wanted to change it but I could not change this text, I thought I would change it in html like this: {% if form.phone.errors %} <p class="alert-p"></p>Incorrect International Calling Code or Mobile Number!</p> {% endif %} Incorrect International Calling Code or Mobile Number! But when I changed it I realized that this method would not work for me because there was a likelihood that users would enter the same phone number and could not understand why it would not save if it did not send the appropriate error message. (phone number is unique) Now there is a problem, in one case, when the user enters the wrong number in the prefix, this time I want my built-in text to drop out as an error message, but when users enter the same number I want to drop out the django-phonenumber-field default Error message Account with this Phone already exists. I will take any advice on how I can solve this problem. -

Send scheduled email django
I have made a small django app to fit all my needs. I will use it on my company level to track simple tasks of couple mehanical engineers. Now, only thing left is to send scheduled emails (every day at noon, if someone is behind with work, he would get an email). Since I'm using Windows and I'll deploy this app on Windows, I can't use cron job (this only works on Linux, as I've seen on forums), which is simple and easy. Only way I found so far was using django-celery-beat. This is not so easy to set up, and I need to run 'worker' each time I run my server. This is a bit above my level and I would need to learn a lot more (and it needs to have a message broker, like RabbitMQ, which I also need to run and learn to implement). I was wondering is there a more easy way to send a simple email every day at noon? I don't want to install additional apps, I wish to keep it simple as possible. -

How to view slideshow in django?
I am building a side project in Django where I have the following feature. There is a list of projects which a name and 10 images associated to it. When the user clicks on the name, there should be a pop up, having the slideshow of all the images associated to that particular project. I am using plain HTML for the templates along with the Django templating language. Can someone please help me out in doing this? My models.py is like class Project(models.Model): project_id = models.AutoField project_name = models.CharField(max_length=100, blank=False) project_img1 = models.ImageField( upload_to='project_images', blank=True, null=True) project_img2 = models.ImageField( upload_to='project_images', blank=True, null=True) project_img3 = models.ImageField( upload_to='project_images', blank=True, null=True) project_img4 = models.ImageField( upload_to='project_images', blank=True, null=True) project_img5 = models.ImageField( upload_to='project_images', blank=True, null=True) project_img6 = models.ImageField( upload_to='project_images', blank=True, null=True) project_img7 = models.ImageField( upload_to='project_images', blank=True, null=True) project_img8 = models.ImageField( upload_to='project_images', blank=True, null=True) project_img9 = models.ImageField( upload_to='project_images', blank=True, null=True) project_img10 = models.ImageField( upload_to='project_images', blank=True, null=True) def __str__(self): return self.project_name PS: The url remains same. It's just a pop-up/modal that opens/closes on button click. I am doing so by using the display:none property in CSS.
