使用条件在字段上进行ActiveRecord搜索

Question

I'm relatively new to Rails and ActiveRecord. I'm storing phone numbers in ActiveRecord fields (phone_number) that can be in a number of formats "+1 928 929 3829" or "393 938 0293" or "392-937-9283" (you get the idea).

Later I'm capturing a 10 digit phone number (so it will always be like "3939380293") and then trying to match that to my ActiveRecord phone number field. The operation I want to do is match against the last 10 numeric characters of phone_number.

I've tried looking at the different SQL-type query constraints that you can use in queries, but I'm having trouble finding exactly what I need or making the logic leap.

Can anyone offer some advice here?

Answer 1

I would do followings

1 - having a VARCHAR field for phone number, which will save numbers in any format (Ex: "+1 928 929 3829" or "393 938 0293" or "392-937-9283")

2 - Have a Activerecord to select the phone number with a regex .

My most favourite regex writers are rubular , regexper
