Accepts Nested Attributes For - edit form displays incorrect number of items ( + !map:ActiveSupport:
- by Brightbyte8
Hi,
I have a teacher profile model which has many subjects (separate model). I want to add subjects to the profile on the same form for creating/editing a profile. I'm using accepts_nested_attributes for and this works fine for creation. However on the edit page I am getting a very strange error - instead of seeing 3 subjects (I added three at create and a look into the console confirms this), I see 12 subjects(!).
#Profile model
class Profile < ActiveRecord::Base
has_many :subjects
accepts_nested_attributes_for :subjects
end
#Subject Model
class Subject < ActiveRecord::Base
belongs_to :profile
end
#Profile Controller (only showing deviations from normal RESTFUL setup)
def new
@profile = Profile.new
3.times do
@profile.subjects.build
end
end
#Here's 1 of three parts of the subject output of = debug @profile
errors: !ruby/object:ActiveRecord::Errors
base: *id004
errors: !map:ActiveSupport::OrderedHash {}
subjects:
- &id001 !ruby/object:Subject
attributes:
exam: Either
name: "7"
created_at: 2010-04-15 10:38:13
updated_at: 2010-04-15 10:38:13
level: Either
id: "31"
profile_id: "3"
attributes_cache: {}
# Note that 3 of these attributes are displayed despite me seeing 12 subjects on screen
Other info in case it's relevant.

I've never had so much difficulty with a bug before - I've already lost about 8 hours to it. Would really appreciate any help!
Thanks to any courageous takers
Jack
