How build AJAX in follow user functionality
I have big challange with AJAX. I made 'Follow User' functionality and don't know how implement AJAX for this... This is my code: In models.py i have: class UserFollowing(models.Model): following_from = models.ForeignKey("Profile", related_name="following_from", on_delete=models.CASCADE) follow_to = models.ForeignKey("Profile", related_name="follow_to", on_delete=models.CASCADE) created = models.DateTimeField(auto_now_add=True, db_index=True) class Meta: db_table = 'users_userfollowing' constraints = [models.UniqueConstraint(fields=["following_from", "follow_to"], name="unique_followers")] ordering = ("-created",) def __str__(self): return f"FROM:{self.following_from} TO:{self.follow_to}" class Profile(AbstractUser, HitCountMixin): slug = models.SlugField(null=False, unique=True) following = models.ManyToManyField("self", through=UserFollowing, related_name="followers", symmetrical=False) def save(self, *args, **kwargs): if not self.slug: self.slug = slugify(self.username) return super().save(*args, **kwargs) In view.py I made function to follow user: def follow_user(request): user = request.user if request.method == 'POST': user_id = request.POST.get('user_id') user_obj = Profile.objects.get(id=user_id) if user not in user_obj.followers.all(): UserFollowing.objects.get_or_create(following_from=user, follow_to=user_obj) else: UserFollowing.objects.filter(following_from=user, follow_to=user_obj).delete() return redirect('profile', slug=user_obj.slug) And in urls.py urlpatterns = [ path("followers/", follow_user, name="follow_user"), ] At least my html template: {% with total_followers=profile.followers.count %} ({{ total_followers }} Follower) <br> {% endwith %} <form action="{% url 'users:follow_user' %}" method="POST" class="follow-form" id="{{ profile.id }}"> {% csrf_token %} <input type="hidden" name="user_id" value="{{ profile.id }}"> <button type="submit" class="follow-btn{{ profile.id }}"> {% if request.user not in profile.followers.all %} Follow {% else %} Unfollow {% endif %} </button> This works very good.

How can I access my sqlite3 database through the html template using Django?
I have a Django application where most of my backend code is in views.py. In the frontend, I'm using an html template, but currently I have hardcoded options that the user can choose from a drop down menu. Those hardcoded options are all available in the sqlite3 database which is used extensively in views.py. Is there a way that I read those fields of database from the html file directly instead of hardcoding them? -

PostGIS on WSL2 - extension "postgis" has no installation script nor update path for version
I am trying to add PostGIS extension to a postgresql database on my WSL2 (with Ubuntu 20.04) for a django project. I have already installed postgresql, postgis and all dependencies with the following: sudo apt -y install postgresql-12 postgresql-client-12 sudo apt install postgis postgresql-12-postgis-3 sudo apt-get install postgresql-12-postgis-3-scripts And everything worked fine. In postgresql, I have already created my db and connected to it: sudo -u postgres psql -p 5432 -h 127.0.0.1 postgres=# CREATE DATABASE dbname; postgres=# \c dbname; But then, when I try to add the postGIS extension with: postgres=# CREATE EXTENSION postgis; I get the following error: ERROR: extension "postgis" has no installation script nor update path for version "3.0.0" And despite searching for similar questions on stackoverflow, I couldn't find any satisfactory solution for my case. Any idea what it could be wrong and how I can solve it? thank you! -

Fieldset values not displaying properly -django
models.py for member table. class Member(models.Model): fullname=models.CharField(max_length=30) companyname=models.CharField(max_length=30) Email=models.CharField(max_length=50) password=models.CharField(max_length=12) contactno = models.CharField(max_length=30,default='anything') i want to display fullname, email, companyname and company number in profile page. models.py for profile table class Profile(models.Model): fullname=models.CharField(max_length=60) contactno=models.CharField(max_length=10) worknumber=models.CharField(max_length=10) email=models.CharField(max_length=30) companyname=models.CharField(max_length=30) timezone=models.CharField(max_length=20) Instead of manually entering the values(data) for fullname, contactno, companyname and email in the fieldset, It should fetch from member table and displayed here. Can we use OneToOne Field or foreign key here, to implement this concept. Thanking You in Advance. You will be highly appreciate, if you could suggest the implementation. -

Django: Type Error after switching to PostgreSQL from SQLite
I changed settings.py and installed psycopg2==2.8.6. I have validation checks in my models that go something like this. rating = models.PositiveIntegerField( blank=True, null=True, default=0, validators=[MaxValueValidator(10), MinValueValidator(0)] ) quantity = models.PositiveIntegerField( blank=False, null=False, default=0, validators=[MinValueValidator(1)]) When I switch to PostgreSQL, there's this error that didn't appear while I was using SQLite. TypeError: '<=' not supported between instances of 'PositiveIntegerField' and 'int' What should I do?
