Hi,
I have a tags table which will be available to all logged in users. The
table has the following structure:
db.define_table('META_TAG',
Field('tag','string',notnull=True),
Field('root_tag','string',notnull=True),
Field('active_ind','string',length=1,default='Y')
)
This table will be rarely (once a month) updated via an administrative
interface.
I read various web2py based examples and gae examples on using memcache.
Each followed a different approach.
As per my understanding from appengine documentation, I have written the
following helper function in a controller to use memcache:
*from google.appengine.api import memcache*
def get_tags():
"""This function returns cached value for META_TAG table"""
tags = memcache.get("tags")
if not words:
words =
db(db.META_TAG.active_ind=='Y').select(db.META_TAG.tag,db.META_TAG.root_tag)
memcache.add("tags",tags)
return tags
else:
return tags
Will the above code ensure that the correct data is always available in the
memcache ?
