Please help. I've tried all i know with no results...
I have an app with a master class using has_many to another class.
When I create a new record with the params showing all fields for
master and the has_many class it seems to work OK. But doing an edit
on the record shows two copies of the has_many class, and checking
mysql shows the two copies.
class Household < ActiveRecord::Base
has_many :people, :dependent => :destroy
has_one :visits, :dependent => :destroy
accepts_nested_attributes_for :people, :allow_destroy => true
accepts_nested_attributes_for :visits
end
class Person < ActiveRecord::Base
belongs_to :household
end
class HouseholdsController < ApplicationController
# GET /households
# GET /households.xml
def index
@households = Household.all
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @households }
end
end
# GET /households/1

def show
@household = Household.find(params[:id])

@v =

@household = Household.new(params[:household])

@visit =
