Defining the current user in views (using custom fields)

Question

Basically, I want to know if there is a request.user replacement when using user users in Django.

My posts / models.py file has the following:

 class Post(models.Model): text = models.TextField() user_id = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='posts') class EduUser(AbstractUser): # additional field 

In my settings file:

 AUTH_USER_MODEL = 'posts.EduUser' 

In my views file:

 if request.method == 'POST': Post.objects.create(text = request.POST['post_content'], user_id = request.user ) 

---

Of course, this returns an error saying "Post.user_id" must be a "EduUser" instance. Any ideas on what needs to replace request.user ? Any help is much appreciated!
