Sanitising a Phone Number input

Rails
1

I want to sanitise a phone number input.

In my UsersController.rb file I have written a method that will take a
string and reduce it to numbers only.

This works find if I call it manually, but in the interests of keeping
DRY I would like to ensure that the code sanitisation method is called
whenever the data is edited (I’m using standard scaffolidng for this
test).

Is there anyway I can do this and keep the code overhead low?

My current sanitisation method looks like this:

private
def numericalise!(*number)
for n in number.phone do
n.gsub!(/[^0-9]/, ‘’)
end
end

Thanks in advance for your time and help.

Why not use

validates_format_of

I want to remove thr formatting, not check for it. It’s to be expected
that user may put spaces, commas, periods and parenthisis in a phone
number and I don’t want to force them in to a particular format.

If I sanitise the code first (then validate it for completeness) then
I’m happy with the data and the user finds the input easy.

Then just call your sanitizer on the attribute in question in the update
or create methods of your controller.

You could use the before_validation callback to clean the data before it
gets validated.
