What property is used to define this?** * label * help_text * required * initial 16. **When models are created and registered in Django and all the migrations are properly run, how are initial permissions created in Django Admin?** * The model must specifically define the permissions. * An additional command must be run from the command line. * A “staff” user must login to Django Admin and create them. * They are create automatically. 17. **What is the modern, native API used in Javascript used to interact with APIs?** * Axios * XMLHttpRequest * jQuery * fetch 18. **On an existing HTML page, all** `
