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
