Auto select current user in Django admin form

May 13, 2015 · Updated: Jul 12, 2021 · by Tim Kamanin

For example, we have the following model with an author field and we want automatically set this value to current user in the admin form:

models.py 
class Post(models.Model):
    title = models.CharField(max_length=255)
    content = models.TextField()
    date = models.DateField()
    author = models.ForeignKey(settings.AUTH_USER_MODEL)

Implement admin class in admin.py with following methods:

admin.py 
class PostAdmin(admin.ModelAdmin):
    def formfield_for_foreignkey(self, db_field, request, **kwargs):
        if db_field.name == "author":
            kwargs["queryset"] = get_user_model().objects.filter(
                username=request.user.username
            )
        return super(PostAdmin, self).formfield_for_foreignkey(
            db_field, request, **kwargs
        )

    def get_readonly_fields(self, request, obj=None):
        if obj is not None:
            return self.readonly_fields + ("author",)
        return self.readonly_fields

    def add_view(self, request, form_url="", extra_context=None):
        data = request.GET.copy()
        data["author"] = request.user
        request.GET = data
        return super(NotesAdmin, self).add_view(
            request, form_url="", extra_context=extra_context
        )


admin.site.register(Post, PostAdmin)
