rails enum, load enum values based on condition is it possible? - ruby-on-rails

Question

lets say i have a model with enum like this :
class Apt < ActiveRecord::Base
enum apt_status: [ :draft, :publish, :unpublish, :waiting ]
end
and in my controller i load my enum like this :
#apt_statuses = Apt.apt_statuses
it's working fine, but what if i want to load my enum values based on user role?
so lets say if i am an admin i want to load all my enum values, and if i am not an admin, i only display 3 enum values
":draft, :unpublish, :waiting"
is it possible? please suggest. many thanks.
btw here is my controller, i really have no idea how to fill my
#apt_statuses
in else condition
ishaveprivilage = Usermaster.joins(:rolemasters, :rolemasters).where(id: #current_user.id, rolemasters: {name: "Super Admin"})
if ishaveprivilage
#apt_statuses = Apt.apt_statuses
else
end
i use my enum in view like this :
<%= f.select :apt_status, options_for_select(#apt_statuses.collect { |s| [s[0].humanize, s[0]] }, selected: #apt.apt_status), {} , class: "form-control" %>

Answer 1

I think I would solve this like so:
class Apt < ActiveRecord::Base
enum status: [:draft, :publish, :unpublish, :waiting]
def self.user_specific_statuses(user)
if user.admin? # define a method in your user model which defines this.
Apt.statuses
else
Apt.statuses.reject { |k, v| k == "publish" } # => all except publish
end
end
end
And then you could call it like this:
Apt.user_specific_statuses(admin_user) # => all statuses
Apt.user_specific_statuses(normal_user) # => only draft, unpublish, waiting

Answer 2

i don't know is this an ideal way to do this or not but i solved it with this approach :
i changed my model enum definition to this :
model : enum apt_status: { draft:0, publish:1, unpublish:2, waiting:3 }
and in my controller i did this :
ishaveprivilage = Usermaster.joins(:rolemasters, :rolemasters).where(id: #current_user.id, rolemasters: {name: "Super Admin"})
if !ishaveprivilage.blank?
#apt_statuses = Apt.apt_statuses
else
temp = Apt.apt_statuses.reject { |k,v| v == 1 } #remove Publish option for non super admin
#apt_statuses = temp
end
if you guys have a better approach, please advise.
