Question

分配創建軌道上現場紅寶石和最近增加。我認爲這可能與我的能力有關：

class Ability 
    include CanCan::Ability 
    def initialize(user) 
     user ||= User.new 
     can :read, :all 
     if user.role? "admin" 
     can :manage, :all 
    end 
    def initialize(user) 
     user ||= User.new 
     can :read, :all 
     if user.role? "coach" 
     can :manage, :all 
    end 
    def initialize(user) 
     user ||= User.new 
     can :read, :all 
     if user.role? "captain" 
     can :manage, :tournaments 
     can :manage, :results 
    end 
    def initialize(user) 
     user ||= User.new 
     can :read, :all 
     if user.role? "teammember" 
     can :manage, :individualresults 
    end 
    end 
end 

感謝任何幫助。如果你想要額外的代碼讓我知道。

Your ability file大概應該是這樣的：

class Ability 
    include CanCan::Ability 
    def initialize(user) 
    user ||= User.new 
    can :read, :all 
    if (user.role? "admin" || user.role? "coach") 
     can :manage, :all 
    end 
    if user.role? "captain" 
     can :manage, Tournament 
     can :manage, Result 
    end 
    if user.role? "teammember" 
     can :manage, Individualresult 
    end 
    end 
end 

Checking a user action against the defined CanCan rules就像做：

if can?(:create, Table)
