Exclude models from makemigrations

[Thomas Brightwell]

I'm working with django-salesforce and have salesforce models in my models.py, as well as local models which point to a Postgres database. I am excluding the salesforce models from the migrate command by using managed = False in a meta class on the models. However, makemigrations still generates migrations for the salesforce model which then never get run by migrate. That's ok but seems a little messy. Is there any way to prevent Django generating migrations for particular models? Have searched the django documentation (I think) pretty extensively for a method.
