[chef] Bug/difference in Chef manage vs. knife for data bag IDs?

[o haya < >]

Hi,

I found that if I use "knife data bag" to create an item in a data bag, the 
item id can include both upper and lower-case letters, but if I use the web 
app to try to create a data bag, it doesn't allow upper-case characters in 
the item id?

The reason I ran across this is that I have a recipe that uses 
node['hostname''] to get the hostname which I then use to select the item in 
the data bag, and in Windows at least, the node['hostname'] seems to be 
returning the (short) hostname in all caps.

In other words, if the hostname is "foo", then node['hostname'] is returning 
"FOO", so I need to make the item IDs in the data bag with caps.

Is this a bug in the web app?

Also, is there a way that I can lower-case the node['hostname'], something 
like lowercase(node['hostname'])?

Thanks,
Jim
