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

lets have model enum :

class apt < activerecord::base   enum apt_status: [ :draft, :publish, :unpublish, :waiting ]  end 

and in controller load enum :

@apt_statuses = apt.apt_statuses 

it's working fine, if want load enum values based on user role? lets if admin want load enum values, , if not admin, display 3 enum values

":draft, :unpublish, :waiting"

is possible? please suggest. many thanks.

btw here controller, have no idea how fill

@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 enum in view :

 <%= f.select :apt_status, options_for_select(@apt_statuses.collect { |s| [s[0].humanize, s[0]] }, selected: @apt.apt_status), {} , class: "form-control" %>

i think solve so:

class apt < activerecord::base   enum status: [:draft, :publish, :unpublish, :waiting]    def self.user_specific_statuses(user)     if user.admin? # define method in user model defines this.       apt.statuses     else       apt.statuses.reject { |k, v| k == "publish" } # => except publish     end   end end 

and call this:

apt.user_specific_statuses(admin_user) # => statuses apt.user_specific_statuses(normal_user) # => draft, unpublish, waiting
