[Myghty-users] Caching a part of a module component

[Ben B. <bba...@am...>]

I have a module component which does some rather CPU and database 
intensive queries, it then passes the results of those queries onto its 
original request. So the process sorta looks like this:
** Do heavy CPU / Database operations **
** Pass objects into component call, save output **
** Pass output of component into m.subexec **

How do I cache the first two parts, so that rather than doing the 
database/comp call, I just check for the cached comp, and pass its 
value directly into the subexec?

I currently am doing something like this with no luck:

             cache = m.cache(component='/dynamic_directory_content.myt')
             if not cache.has_key('diroutput'):
                 del cache
                 # WHOLE BUNCH OF DATABASE STUFF HERE
                directoryContent = 
m.scomp('/dynamic_directory_content.myt', OBJECTS, **params)
                 m.subexec(path, directory_content = directoryContent, 
**params)
             else:
                 dirContent = cache.get_value('diroutput')
                 m.subexec(path, directory_content = dirContent, 
**params)

I have a m.cache_self inside dynamic_directory_content, setting the key 
'diroutput'. The error it gives is:
Myghty Template Error

Error:
Error: 'diroutput'

File:
/path/components/dynamic_directory_content.myt line 347

Context:
  344: aggregateTotals
  345: </%args>
  346: <%init>
347: m.cache_self(key='diroutput',expire_time=600)
  348: from datetime import date
  349: </%init>
  350:

Or is there a better approach to caching a chunk of a module component?

Thanks,
Ben
