ruby-on-rails - Forem Group 有徽章

Question

我正在尝试完成一个系统，我可以将用户放入名为“主持人”的组中，他们将获得一个带有文本主持人和组面板中指定颜色的引导徽章。

然后假设我将成员放在一个捐赠者组中，他们也会获得徽章。我还计划让他们的用户名由最高优先级组（在组面板中设置的优先级）着色，这将在帖子视图和主题视图中为他们提供该颜色。

我并不是要求实现这一点，只是想自己弄清楚如何去做。

Answer 1

  class User < ActiveRecord::Base
    has_and_belongs_to_many :groups  # a user can be associated to a group that doesn't have a corresponding badge
    has_many :badges  # the association to a group through a badge is also possible but due to business constraints, this may not neccessarily be so
  end


class Badge < ActiveRecord::Base
    belongs_to :user
    belongs_to :group
  end

class Group < ActiveRecord::Base
    has_and_belongs_to_many :users;
  end
