i have buying , selling rails app, users have 2 roles buyers , sellers want show records on homepage how many buyers there on site , how many sellers on site. using user.count shows user registered on site

my seeds.rb

['buyer', 'seller'].each |role|   role.find_or_create_by({name: role}) end

models

role.rb

class role < activerecord::base     has_many :users end

users.rb

   belongs_to :role    def has_role? test_role        role.id == 2        role.id == 1    end

using role object count role:

role = role.find_by(name: 'buyer') user.where(role: role).count

or can include roles table , query through users:

user.includes(:role).where(role: {name: 'buyer'}).count

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
