Hi,
I am searching for a record using "where":
@profile = Profile.where(:user_id => current_user.id)
This returns:
=> [#<Profile id: 6, user_id: 19, last_subject_id: 6, last_book_id: 2,
last_chapter_id: 1, last_section_id: 1, last_subsection_id: 1,
last_minisection_id: 20, about: nil, image: nil, created_at: "2013-03-13
01:45:44", updated_at: "2014-01-30 02:11:54", students_last_subject_id:
6, students_last_book_id: nil, students_last_chapter_id: nil>]
I am trying to then access "students_last_subject_id" using several
methods including @profile.students_last_subject_id,
but it keeps returning nil. With the enclosing brackets i am guessing
this is not a hash..
Can anyone help?
Thanks,
Dave

Nope. where returns an array containing all the records it finds, even if it's only one. If you know, or at least are pretty sure, your search will only give one row object, you can use find_by, or just pull the first element from the where's array:
@profile = Profile.find_by(:user_id => current_user.id)
@profile = Profile.where(:user_id => current_user.id).first
