Hi ,

I have a table called streams which contain the columns:  
id name resolution framerate bitrate

i have created a web application which is working fine.  
Here are my doubts:

1)i want to give a tag to my table to find the data from the table.i  
tried like below but i am not able to give throwing errors on console:

befor giving the tag i have created an instance and then i applied  
tagging.can give me idea to clear this?

> > s = Stream.find(1)  
> > =\> #\<Stream id: 1, name: “dust.mpeg2”, resolution: “1920x1080”,  
> > codecname: “mpeg2”, framerate: “30fps”, created\_at: “2008-12-04  
> > 16:23:23”, updated\_at: “2008-12-04 16:23:23”\>

> > s.tag\_with(‘d1 cif 720p’)
