vue --- 07 payments and orders

In order to facilitate the development, and future maintenance of the project, we once again create a sub-application orders to complete the next payment orders and order functions.

cd luffy/apps
python ../../manage.py startapp orders

Registration sub-applications, settings / dev.py, Code:

= INSTALLED_APPS [
     # sub-applications 
    . . . 
    
    ' Orders ' ,
