Rails Validations, number + letters + spaces

Question

Looking for a Rails validation that will only allow letters, numbers, and spaces. This will do letters and numbers, but no spaces. I need spaces.

validates_format_of :name, :with => /^\w+$/i,
:message => "can only contain letters and numbers."

Answer 1

validates_format_of :name, :with => /^[a-zA-Z\d ]*$/i,
:message => "can only contain letters and numbers."

Here is only Number, Letters ans spaces.

Is that exactly what you need ?
