在我的 Rails(仅限 api)学习项目中,我有 2 个模型,Group 和 Album,它们具有一对多的关系。当我尝试使用嵌套的(已经存在的)专辑保存组时,我收到以下错误,ActiveRecord::RecordNotFound (Couldn't find Album with ID=108 for Group with ID=)
. 我正在使用jsonapi-serializer gem。下面是我目前的设置。任何帮助表示赞赏。
楷模
class Group < ApplicationRecord
has_many :albums
accepts_nested_attributes_for :albums
end
class Album < ApplicationRecord
belongs_to :group
end
组控制器#create
def create
group = Group.new(group_params)
if group.save
render json: GroupSerializer.new(group).serializable_hash
else
render json: { error: group.errors.messages }, status: 422
end
end
GroupsController#group_params
def group_params
params.require(:group)
.permit(:name, :notes, albums_attributes: [:id, :group_id])
end
序列化器
class GroupSerializer
include JSONAPI::Serializer
attributes :name, :notes
has_many :albums
end
class AlbumSerializer
include JSONAPI::Serializer
attributes :title, :group_id, :release_date, :release_date_accuracy, :notes
belongs_to :group
end
示例 JSON 有效负载
{
"group": {
"name": "Pink Floyd",
"notes": "",
"albums_attributes": [
{ "id": "108" }, { "id": "109" }
]
}
}
