It's time for a better solution override get_form method

lets say way have this model

models.py

from django.db import models
from django.contrib.auth.models import User


class Post(models.Model):
    title = models.CharField(max_length=256)
    content = models.TextField()
    author = models.ForeignKey(User, on_delete=models.CASCADE)


    def __str__(self):
        return self.title

admin.py

class PostAdmin(admin.ModelAdmin):
    # you should prevent author field to be manipulated 
    readonly_fields = ['author']

    def get_form(self, request, obj=None, **kwargs):
        # here insert/fill the current user name or id from request
        Post.author = request.user
        return super().get_form(request, obj, **kwargs)


    def save_model(self, request, obj, form, change):
        obj.author = request.user
        obj.author_id = request.user.id
        obj.last_modified_by = request.user
        obj.save()

admin.site.register(Post, PostAdmin)
