Rails - Aug 2006 - Convert currency into number

1) A user enters $100 into a textfield and submits, I need to strip off 
the $ sign before it gets saved to the db.

2) The name of the field is "price", why does params[:price] upon 
submitting have nil value?

1.

value = params[:price].gsub(/$\$/, '''')  # strip off a dollar
sign if it''s
the first character

2. Not sure. What does you log say? is the param :price => $100 or is it
:model_name => {:price => $100}

1.  "$100.00".scan(/[.0-9]/).to_s will return 100.00.  If you
don''t want
decimal values then remove the period, but know that it will return 
10000

2.  You need the model in front of it.  e.g. 
params[:your_model_name][:price]

Hope this helps.  Perhaps there is a better way to achieve number one, 
but that was the quickest thing I thought of.

Regards,

Michael
