Question

标题说明了一切。如何定义与我的模型相关联的ActiveStorage::Attachment的关系？我希望comment和react能够photos以及Post。

class Post < ApplicationRecord
  belongs_to :user
  has_many :comments, as: :commentable
  has_many :reactions, as: :reactionable

  has_many_attached :uploads
end

Answer 1

至少你可以通过引入一个中间模型（这将是喜欢/反应的目标并将主持上传）来做到这一点。

class Post
  has_many :likable_photos
end

class LikablePhoto
  has_many :likes, as: :likeable # or however else you decide to store likes
  has_many :reactions, as: :reactionable    

  has_one_attached :upload
end

如何添加喜欢和评论ActiveStorage blob
