Question

I using devise to allow users to register on my website. I have field for them to put in their telephone number when registering.

I however want to split the telephone field into 3 parts so you put in different parts of the number, kind of like a date.

Is it possible in rails to do something similar like you would with a date? When you have a date select on a form it gives the field names:

model[date(1i)]
model[date(2i)]
model[date(3i)]

Is this possible with other fields?

Cheers

I do not believe it is possible to cajole the date_select/select_date family into doing what you want.

You could try to mirror the DateTimeSelector class for your purposes: https://github.com/rails/rails/blob/master/actionpack/lib/action_view/helpers/date_helper.rb

But why not just deal with this in the controller? You can slice and dice the input any way you want. If it’s a one-time thing, I would do it that way. Otherwise, it might be worth your time to solve the problem in general, in which case you can make a gem for the world to use… although I think these ‘i’ suffixes are only useful for dates and times as far as ActiveRecord is concerned.
