Re: [Rails] Help with find

Person.where.limit returns a collection, you can to use .first, .last, .each. etc to access the element(s) or you can to use Person.find(34) in this case.

Folks
 When im in rails 3.2 console i can do this just fine

 p = Person.last
 p.last_name

 and it prints the last name.

 But when i try to find it by the id, its able to locate the single
record and store it in my variable p, but i cant print the last_name
column. For example.


  p = Person.where(id: 34).limit(1)

  "printing p here shows all the columns"

  p.last_name says this

NoMethodError: undefined method `last_name' for
#<ActiveRecord::Relation:0x000000055f8840>

any help would be appreciated, thanks.
