How to save multiple data

hi,

i have 3 models:

class Company < ActiveRecord::Base has_many :company_branches end

class CompanyBranch < ActiveRecord::Base has_many :branch_contacts belongs_to :companies end

class BranchContact < ActiveRecord::Base belongs_to :company_branches end

i am getting following parameter in action: form can add multiple branches and their contacts dynamically

Parameters: {"company"=>{"company_type_id"=>"1", "company_name"=>"c22222222", "head_office_address"=>"cxczxczx", "notes"=>"ewewq"}, "commit"=>"Create", "contact_information"=>{"0"=>["b1c1", "b1c2"], "1"=>["b2c1", "b2c2"]}, "branch_detail"=>{"0"=>"b1", "1"=>"b2"}}

how to save them in respective table

i tried

if @company.save   all_branchs = params[:branch_detail]   all_branchs.each do |q|     param_branch = {:branch_detail => q[1]}     @company_branches = CompanyBranch.new(param_branch)     @company_branches.company_id = @company.id     if @company_branches.save       all_branch_contacts=nil       all_branch_contacts = params[:contact_information]       logger.debug all_branch_contacts.to_yaml       all_branch_contacts.each do |p|         param_hash = {:contact_information => p[1]}         @branch_contacts=BranchContact.new(param_hash)         @branch_contacts.branch_id = @company_branches.id         @branch_contacts.save       end     end   end end

but it's saving junk in contact table.

Thanks in advance
