hi all,

i am getting the following warning for "numeric_slug = /^[0-9]+$/" this
line in my model class,
"warning: character class has `-' without escape"

can anyone know the what is the escape character used in regex ?
i am using Ruby:1.8.7,gem:1.6.2,Rails:2.3.11.
Also, i want to up grade my current version of Ruby ,Rails and gem with
latest one ,but i don't know what are compatible and stable latest version
for ruby and rails with
rubygem ?
can anyone have any suggestion on this for up gradation of the
environment ?
