Setting Default Value in .build method - ruby-on-rails

Question

Im trying to submit a nested form when you create a school, you can also create a admin with it. When I try to save the form with the default value of owner set to true and status set to active, it saves the form but doesnt save those values in the database
class SchoolsController < ApplicationController
before_filter :authenticate_admin!, except: [:index, :new, :create]
def show
#school = School.friendly.find(params[:id])
end
def new
#school = School.new
#admin = #school.admins.build(:owner => true, :status => "active")
end
def create
#school = School.new(school_params)
if #school.save
redirect_to new_admin_session_path
else
render 'new'
end
end
def edit
#school = School.find_by_slug(params[:id])
end
def update
#school = School.find_by_slug(params[:id])
if #school.update_attributes(school_params)
redirect_to :action => 'show', :id => #school
else
render :action => 'edit'
end
end
def team
#teams = Admin.all
end
private
def school_params
params.require(:school).permit(:school_name, :latitude, :longitude, :radius, admins_attributes: [ :first_name, :last_name, :email, :password, :password_confirmation, :image ])
end
end
class School < ActiveRecord::Base
has_many :admins
accepts_nested_attributes_for :admins
extend FriendlyId
friendly_id :school_name, use: :slugged
def should_generate_new_friendly_id?
school_name?
end
# Validation
validates :school_name, presence: true, uniqueness: true
validates :latitude, presence: true
validates :longitude, presence: true
validates :radius, presence: true, numericality: { only_integer: true }
