Getting user's tweets using tweestream gem

Hello,

I’m using the ‘twitter’ gem and the following code [1] to collect user
tweets. I wonder if there is any way to achieve the same result using
‘tweestream’.

Tweestream gem seems able to ‘track’ in real time anything that goes on
twitter, it’s awesome for gathering random (or less random) data but
apparently
there is no way to get grab all user tweets at once and disconnect.

Is that so or am I missing something?

thanks
