[web2py] Re: DAL query CONVERT field
In the trunk pyDAL version this should be possible:
db(db.table1.field1.cast('text').like('%somestring%')).select(db.table1.ALL)
While that's not available:
from pydal.objects import Expression
dialect = db._adapter.dialect
db(Expression(db, dialect.cast, db.table1.field1, dialect.types['text'],
'text').like('%somestring%')).select()

[web2py] Re: Issue with defaultdict(list)
Drew most likely what's happening is a variation of this
g = defaultdict(list)
g['foo'] = {'id': 1} # this could be any dictionary
g['foo'].append('someValue')
AttributeError: 'dict' object has no attribute 'append'
Note that defaultdict only gives you the default if the key doesn't have a
value already .

[web2py] Re: Issue with defaultdict(list)
I think I've narrowed it down to having an error somewhere in my 'students' controller. 1. If I remove all other functions within that controller, it works. 2. If I create a new controller and only have that function, it works. 3. If I put the same exact code in another existing controller, it works. I will have do some more testing to figure out where my actual problem lies.Will report back with any results. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

I was doing some testing and it seems to work perfectly fine when I run it
from default.py. However, any time I try to run it from the controller I
need it in, it doesn't work. I even created the "test" function that worked
for you, and I still get the "AttributeError: 'dict' object has no
attribute 'append'". This one has really got me scratching my head.

Not sure what you mean. Where does the session ID produced by the function come from, and how is the "real value" defined? What are you suggesting different from Massimo's approach.

What if I cache on disk the result of a function that returns the session id and I check if it corresponds to the real value? In this case how can I force to logout all other user logged in with the same username? I would prefer to give precedence to the last one who login.

This controller worked fine for me:

g = defaultdict(list)
g['somekey'].append('somevalue')
return response.json(g)
You probably have a bug in your view. You can show us the code if you want.
