Rails 3 Active Record query returns "undefined method `loaded?'' for #<Array:0x126a4c>"
I am getting this error on an rspec test:
undefined method `loaded?'' for #<Array:0x126a4c>
When I call:
Practice.includes("practice_members").all
Practice has_many :practice_members
PracticeMember belongs_to :practice
Practice.all returns:
[#<Practice id: 6, name: "Practice One", created_at:
"2010-12-09 15:40:46",
updated_at: "2010-12-09 15:40:46">]
PracticeMember.all returns:
#<PracticeMember id: 9, practice_id: 6, name_last: "Aaaaz",
name_first:
"Aaaba", name_middle: "Aaabb", created_at: "2010-12-09
15:40:46",
updated_at: "2010-12-09 15:40:46">, #<PracticeMember id: 10,
practice_id: 6,
name_last: "Aaabc", name_first: "Aaabd", name_middle:
"Aaabe", created_at:
"2010-12-09 15:40:46", updated_at: "2010-12-09
15:40:46">]
So the association on practice_id is correct on both practice members. It is
unclear to me why this should be failing... am I missing something?
Thanks,
David

But anyway I tried out changing PracticeMember.practice_members to PracticeMember.global_practice_members but still get the same error. By the way as far as documentation and explaining myself, I am a bit confused about the conventions for explaining class methods: I know that I can explain instance methods like: PracticeMember#practice_members --- is this correct, that this would refer to the instance and not the class method? But how do I explain the self.practice_members method?
