# config valid only for Capistrano 3.1
lock '3.1.0'

set :application, 'woi'
set :repo_url, '[email protected]:sanjay-salunkhe/cap.git'
set :branch, "master"
set :deploy_via, :remote_cache
set :stages, ["production"]

# Default branch is :master
# ask :branch, proc { `git rev-parse --abbrev-ref HEAD`.chomp }

# Default deploy_to directory is /var/www/my_app
 set :deploy_to, '/home/webuser/apps/cap/'

# Default value for :scm is :git
# set :scm, :git

# Default value for :format is :pretty

namespace :deploy do

  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      # Your restart mechanism here, for example:
       execute :touch, release_path.join('tmp/restart.txt')
    end
  end

  after :publishing, :restart

  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
      # Here we can do anything such as:
      # within release_path do
      #   execute :rake, 'cache:clear'
      # end
    end
  end


  desc 'precompiling assets..............'
  task :composer_install do
    on roles(:web) do
      within release_path do
        execute :rake, "assets:precompile RAILS_ENV=production"

Finally i manged to deploy my app using capastrano 3.Actually i had not included below two lines in my capfile.

 require 'capistrano/rvm'
require 'capistrano/rails'

After including these two lines my issue has been resolved.
