Accessing has_many model records - ruby-on-rails

Question

I have the following 2 tables defined in migrations
class CreateUsers < ActiveRecord::Migration
def self.up
create_table :users do |t|
t.string :name
t.string :phone
t.string :email
t.string :address
t.string :resume
t.timestamps
end
end
end
Class CreateResumeSections < ActiveRecordMigration
def self.up
create_table :resume_sections do |t|
t.string :section_name
t.string :html
t.timestamps
end
end
end
I have following 2 models
class User
has_many :resume_sections, :dependent => :destroy
attr_accessor :section_layout
after_save :save_sections
private
def save_sections
self.section_layout = ###Someother logic here that sets this variable
end
end
class ResumeSection
belongs_to :user
end
In my users_controller, I have the following code
class UserController < ApplicationController
def create
#user = User.new(params[:user])
#user.save
#user.section_layout.each {|key,value|
rs = ResumeSection.new(:section_name => key, :html => value, :user => #user)
rs.save
}
end
end
In my view I have the following code
<% #user.resume_sections.each do |section| %>
<%= section.section_name %>
<%= section.html %>
<% end %>
I get Undefined method error for Nil:NilClass in the view. The expression #user.resume_sections is not returning to me the records that I just created and saved in the UsersController. Instead it returns nil to me. When I check the database the records are there.
Is the expression #user.resume_sections the correct expression to access these records?
Thanks

It seems to me that your you missed something in you migrations. ResumeSection needs to have and integer field called user_id. Just create a new migration that has something like this in it:
def change
add_column :resume_section, :user_id, :integer
end
