Re: [web2py] Modelless app no longer works with web2py 2.0.x ???

2012-09-12 Thread Andrew W 
Perfect !  Thanks for the quick response.   
I saw your solution above, but assumed that you had added it to github.  
All's Good.

One more question please (which I asked on web2py slices):
How to use auth.wiki with movuca.   There was a web2pyslices post in 
relation to plugin_wiki, and I was wondering what has changed for 
auth.wiki.  The two together makes sense (I think).

So if I understand you correctly you lighten the server load and get 
quicker sites when you add change db=DAL(...) to 
db=DAL(...,lazy_tables=True)
I like the everything gets better option :)

 imagine you have

 models/db.py

 db = DAL(...)
 db.define_table(table1.)
 db.define_table(table2.)

 ...
 db.define_table(table30.)

 So, for each request (I mean every time user hits an url or click on 
 something) all that 30 tables will be imeddiatelly instantiated even if the 
 requested page does not need to all the 30 tables.

 The process of table definition involves some logic such as instantiate a 
 new Table object, check all the fields, do migrations, check reserved 
 keywords, check the tablename atc...

 Now if you turn

 db = DAL(... lazy_tables=True)

 for each request web2py will just store some data in a dictionary 
 {tablename: {fields: ., options:}, no table will be 
 instantiated ultil needed.

 So when in your program you do 

 db(db.table1),select() # in this time web2py will fire the table 
 instantiation and all the process, so it will happen only for the table you 
 need and you saved 29.

 Thats it.

2012-09-09 Thread Andrew W 
Thanks Bruno for the comments,
I have been looking into the modelless approach so it's interesting to read 
your views on the new lazy_tables feature.I think it is a lot simpler 
creating an app that follows the MVC structure out of the box, so the lazy 
option sounds like a great breakthrough   (although I still don't quite 
really understand what a lazy table is).
