treating 'string'+var as method

[bmgz]

I am a new Ruby recruit (thanks to *ahem*, Rails)..
What is the best way to do this:

* obj.'string'+var as a method?

I am currently using:

* obj.send('string'+var)

...which works fine, but is this correct or bad practice?

That's ok. As Ross pointed out you can also use obj.send("string#{var}").
But I would not use eval - there's just too much that can go wrong
security wise.

Kind regards
