Hi guy, I'm using web2py version 2.7.2 with ubuntu 12.04.
I made a simple db.py:
state = db.define_table('state',
Field('name','string',label=T('State')))
city = db.define_table('city',
Field('name','string',label=T('City')),
Field('state_id','reference state',required=True,
requires=IS_IN_DB(db,'state.id', lambda reg: '%(city)s -
%(state)s' % dict(city=reg.name,state=reg.country_id.name))))
When I make a query:
db(db.city.name.contains('rio')).select(db.city.name,db.city.id,
db.state.name,join=db.city.on(db.city.state_id == db.state.id))
it takes 180ms, but when i make
db(db.city.name.contains('rio') & db.city.state_id == db.state.id).select(
db.city.name,db.city.id,db.state.name)
it takes 24 seconds waiting and 5 seconds to retrieve.
Looking inside, I saw that web2py is making a WHERE clause instead of a
JOIN.
It's normal?
