Hi there, Anybody knows how to use regex to validate street name field? I want to avoid things like "st asdkskjfls çsdfksçf".

I don''t think a regex can save you here. Ask yourself a higher-level question. Why are you gathering the address information, and why isn''t it optional? If it''s to send something of value to the person you''re requesting it from by postal mail, or if you''re using it to help them find something they need nearby their home, then rest assured they will enter it with care. If it''s anything less, you invite this sort of abuse, and you should either just stop asking the question, or realize that a significant percentage of entries will be "undeliverable" (to use the Post Office''s bloodless euphemism). By the way, I believe the USPS has an address checker API, IIRC, I''ve used it from PHP before, and there may be a Gem wrapper for it as well. Ditto FedEx if you''re using them for delivery.

Walter Im using address to geocoding. Do you know if exists an address check plugin or gem to do this work?

+1 to everything Walter has said, as well.
I haven''t thought about this a lot, but doesn''t this apply to
everything in
terms of user input? Doesn''t this really enter the realm of a basic
guideline, principle, or law for UI? (I remember something like this being
applied to database design.)
Don''t make people enter data that they don''t care about.
Don''t make people enter data that doesn''t affect
anything.
Carefully evaluate whether people really need to enter data.
If people feel free to enter garbage in a field, should that data
really be asked for?
Aren''t there, potentially, corollaries to this? For instance, Always
allow
the people entering data to easily correct or remove their data.
