You can override the .save_model(…) method [Django-doc] to set the .updated_by and .created_by fields, depending on whether change is True or False:

from django.contrib import admin

class LinkAdmin(admin.ModelAdmin):
    
    def save_model(self, request, obj, form, change):
        if not change:
            obj.created_by = request.user
        obj.updated_by = request.user
        return super().save_model(request, obj, form, change)

admin.site.register(Links, LinkAdmin)

If you need this for a large number of models, you can make a mixin, and then use that for all sorts of models:

class CreateUpdateUserAdminMixin:
    
    def save_model(self, request, obj, form, change):
        if not change:
            obj.created_by = request.user
        obj.updated_by = request.user
        return super().save_model(request, obj, form, change)

and then use the mixin with:

class LinkAdmin(CreateUpdateUserAdminMixin, admin.ModelAdmin):
    pass

class OtherModelAdmin(CreateUpdateUserAdminMixin, admin.ModelAdmin):
    pass

admin.site.register(Links, LinkAdmin)
admin.site.register(OtherModel, OtherModelAdmin)

Note: normally a Django model is given a singular name, so Link instead of Links.
