What are some guidelines for structuring cherry applications?

I am writing a cherry application and I was wondering what is the best way to structure my handlers and code for larger applications?

I understand that assignment is simple through cherrypy.root, but what are some methods of writing handlers and their purpose?

(Let me prove my confusion!) My initial thought was to write a standard handler class that runs the template to run based on the current URL combination or class / method. Then I would assign one instance of this handler several times to the page creation path. I do not see this working, as recursive links will not work correctly.

So, given the fact that I am already drawing spaces for what my own source code should look like, I would like some pointers and examples!

Feel free to ask me any detailed questions. Despite the fact that there is a lot of material for the vortex textbook, it tends to only scratch the surface.

This question is wildly subjective, but I will give it a chance.

  • First of all, always keep the database and data code separate from the web code. I have many small files with one class in a folder DB/, all of which are combined into a file Base.py, for example:

    Web /
  Base.py - The main "base" class that includes classes in others
   ,  -  __init__
  Users.py - ,   ,  ,  "DB/Users.py" 
      ..   ( 
       DB)
 ...
DB/
  Base.py -    DB,      DB. 
   SQLAlchemy/      , 
      ..     ,    
  ,     ..   ,  
        
  Users.py -     /  .. DB
 ...
 /
  (HTML-  )
 /
  (  /CSS/javscript   ..)
    , __init__.py , , python

    import Users

    , , from Users import Users , Users.py from Base import x, . , , : -P
