我正在开发一个反应原生应用程序，作为项目的一部分，我正在使用Ruby on Rails 5在API模式下构建一个API，ActiveAdmin用于管理界面。我已经设置好了一切，而且一切正常。
在想到 API 之前，我得到了一个文件中的数据，我需要使用 rails 复制其结构，这样它就可以进行内容管理。
但我似乎无法正确获得活动记录关联。
这是数据文件的示例...
{
name: 'Scottish Stoics',
days: [
{
day: 'Monday',
meeting: [
{
name: 'Meeting one',
location: 'Test',
startTime: '11.00',
address: 'Test Street',
meetingLength: '1 Hour',
city: 'Edinburgh',
},
{
name: 'Meeting two',
location: 'Test',
startTime: '10.00',
address: 'Test Street',
meetingLength: '1 Hour',
city: 'Edinburgh',
},
{
name: 'Meeting three',
location: 'Test',
startTime: '10.00',
address: 'Test Street',
meetingLength: '1 Hour',
city: 'Edinburgh',
},
],
},
{
day: 'Tuesday',
meeting: [
{
name: 'Meeting one',
location: 'Test',
startTime: '10',
address: 'Test Street',
meetingLength: '1 Hour',
city: 'Edinburgh',
},
{
name: 'Meeting two',
location: 'Test',
startTime: '10',
address: 'Test Street',
meetingLength: '1 Hour',
city: 'Edinburgh',
},
{
name: 'Meeting three',
location: 'Test',
startTime: '10',
address: 'Test Street',
meetingLength: '1 Hour',
city: 'Edinburgh',
},
],
},
],
},
{
name: 'Scottish Cycling Group',
days: [
{
day: 'Sunday',
meeting: [
{
name: 'Meeting one',
location: 'Test',
startTime: '11.00',
address: 'Test Street',
meetingLength: '1 Hour',
city: 'Edinburgh',
},
{
name: 'Meeting two',
location: 'Test',
startTime: '10.00',
address: 'Test Street',
meetingLength: '1 Hour',
city: 'Edinburgh',
},
{
name: 'Meeting three',
location: 'Test',
startTime: '10.00',
address: 'Test Street',
meetingLength: '1 Hour',
city: 'Edinburgh',
},
],
},
{
day: 'Tuesday',
meeting: [
{
name: 'Meeting one',
location: 'Test',
startTime: '10.00',
address: 'Test Street',
meetingLength: '1 Hour',
city: 'Edinburgh',
},
{
name: 'Meeting two',
location: 'Test',
startTime: '10.00',
address: 'Test Street',
meetingLength: '1 Hour',
city: 'Edinburgh',
},
{
name: 'Meeting three',
location: 'Test',
startTime: '10.00',
address: 'Test Street',
meetingLength: '1 Hour',
city: 'Edinburgh',
},
],
},
],
}
我有一个小组模型，一天模型和一个会议模型。
群
belongs_to :day
belongs_to :meeting
会议
has_many :groups
日
has_many :groups
我得到了这个结果。
[
{
id: 1,
name: "Scottish Stoics",
created_at: "2018-03-19T11:47:50.818Z",
updated_at: "2018-04-12T10:50:05.179Z",
day_id: 7,
meeting_id: 81
},
{
id: 2,
name: "Scottish Cycling Group",
created_at: "2018-03-19T11:47:57.498Z",
updated_at: "2018-04-11T22:13:26.656Z",
day_id: 7,
meeting_id: 83
},
]
现在我可以使用 jbuilder 来获取日期名称和会议名称，这很好，但我不能做的是选择一天的多个会议，以及组的多天。这种数据结构在Rails中是否可行？
我无法确定我是否应该使用不同类型的关联，有人能为我阐明这一点吗？
假设顶级嵌套对应于组，您可以形成如下关联：
日
has_many :meetings
belongs_to :group
会议
belongs_to :day
群
has_many :days
has_many :meetings, through: :days
虽然我的印象是在 JSON 中提供的它应该是meetings而不是meeting以保持它休息
