How to make Django models refer to each other bidirectionally?
I am trying to create a relationship where a blog post can be assigned any number of tags, and a tag can be associated with any number of blog posts. But I'm having difficulty setting up this bidirectional relationship. Right now, to create a blog post and assign any number of tags, here is my model for the posts: class Post(models.Model): title = models.CharField(max_length=200, unique=True) slug = models.SlugField(max_length=100, unique=True, null=True, blank=True) author = models.ForeignKey(User, on_delete=models.CASCADE) updated_on = models.DateTimeField(auto_now=True) tags = models.ManyToManyField("Tags", blank=True) content = RichTextUploadingField() created_on = models.DateTimeField(auto_now_add=True) And the model defining the tags: class Tag(models.Model): name = models.CharField(max_length=20, unique=True) This works. I can log into the admin interface and create a bunch of tag objects, then create a post object and assign it any number of those tags. But let's say I also want to do the opposite. I want to be able to log into the admin interface, select a tag object, and then associate it with any number of post objects. I tried to do this by defining a ManyToManyField in the Tag model like so: class Tag(models.Model): name = models.CharField(max_length=20, unique=True) posts = models.ManyToManyField("Post", blank=True, related_name="posts") This does show a list of posts on the change … -

Django adding and removing form ManyToMany field: AttributeError: 'QuerySet' object has no attribute 'add'
I am trying to add users to a many to many fields in my course model buy I am getting an error: Course.course_dislikes.through.objects.filter(course__course_code=code,course__course_university=university).add(request.user) AttributeError: 'QuerySet' object has no attribute 'add' My intention is to filter my Course model based on course code and add a user to like a field or remove it when the user dislikes. Now I know I cannot use get since there may be two objects with the same course code. Currently, I am trying to do this by: Course.course_likes.through.objects.filter(course__course_code=code).remove(request.user) I have tried with get but it gaves me an error that two objects with the same name exist which is understandable since get has to return one unique object.

Stack Inline Multiple Django Models in Admin with indirect relationship
I have the following three models class Participant(models.Model): participant_id = models.AutoField(primary_key=True) pin = models.CharField(unique=True, max_length=4, validators=[RegexValidator(r'^\d{1,10}$')]) class Teacher(models.Model): teacher_id = models.AutoField(primary_key=True) participant_id = models.OneToOneField(Participant, on_delete=models.CASCADE) email = models.EmailField() compensation_id = models.OneToOneField(Compensation, on_delete=models.CASCADE) class Compensation(models.Model): compensation_id = models.AutoField(primary_key=True) wage = models.DecimalField(max_digits=6, decimal_places=2) To summarize, Participant has different types one of them is Teacher (OneToOne relation). The teacher is one type of employee that is compensated with and it's related (OneToOne relation) with Compensation Model I want to create an admin form by stacking Participant Teacher Compensation The problem: I am using Participant as a primary model and stacking teacher to it. However, when I try to stack compensation to it, it apparently doesn't work due to missing foreign key relation between Participant and Compensation models. An easy way out would be to have the fields of the Compensation model in the Teacher Model. However, it would create redundancy when I want to associate other types of Participants to it. What could potentially be a solution to this? I am open to altering the model if it makes thing any easier or less complicated. P.S. There are also other types of participants (Child, Parent) that I have not mentioned. -

How to add to the database outside of the admin site in django

Why is clang failing when building wheel for psycopg2?
I know this question or various forms of it has been asked. I am just trying to follow the Django tutorial on Heroku - which involves installing django-heroku, which has psycopg2 as a dependency. I am running MacOS Catalina, 10.15.3. I know one work around is to download the binary with pip install psycopg2-binary, but then I don't know how to get pip to recognize psycopg2-binary and stop trying to install psycopg2 from source when I run pip install django-heroku. So I suppose if someone could help me figure out that workaround, that would also suffice - although at this point I think I'm just gonna use Node. In any case, I feel like it's most likely just another instance of Catalina breaking things, but it would be nice to know how to fix this in case I ever have to use django-heroku/psycopg2. I have upgraded homebrew, reinstalled pyenv/python3.7.4, updated pip. I have openssl 1.1.1g installed (homebrew). I recently reinstalled XCode - but just to be sure it wasn't my compiler's fault, I installed homebrew clang using brew install llvm.

How does Django decrypt EncryptedCharField fields?
So I've got a field in my Postgres database that is a bytea type. I know the decrypted value and also the key, but can't figure out how to get from that raw database value to the decrypted string. I believe I'm looking for the algorithm that Django uses to decrypt these values and how I can use that to encrypt another string. Django supposedly uses the package Keyczar, which mentions using Crypter package to encrypt/decrypt things. I'm unable to install that package so I'm not sure how to go about this in another way. I ultimately want to update a value in the EncryptedCharField field in my database since it is not valid anymore - is there a way to get this encrypted value online or within Python?
