Web development -

Caution: boring question

Have anyone worked on anything like a form builder like by giving a name generating a table with default columns and new folder for controller , models inheriting a base class that can provide a CRUD functionality ?

In my company they have a cool module builder that allow you to add any field email ,file, password,connector field - connect two modules one 2 one relationship clonable field many to many built on php.

I tried and created one using python Flask framework but without restarting app the routes are not getting registering asked in stack overflow got downvoted

Any thoughts?
