Question

我遇到与HABTM关系的情况，必须将shop和event模型实例传递给ShopEventsController才能将事件分配给商店。

路由配置如下：

resources :shops, except: [:create, :destroy] do
  resources :events, controller: 'shop_events', only: [:index, :create, :destroy]

什么为我们提供了以下终点：

/shops/:shop_id/events
/shops/:shop_id/events/id

ShopEventsController具有strong_params的定义如下：

def shop_event_params
  ActiveModelSerializers::Deserialization.jsonapi_parse!(params,
   only: [
    :shop,
    :event
  ])
end

我不知道如何从RSpec请求规范中传递有效参数...

简而言之，我认为我需要：

ActiveModelSerializers::SerializableResource.new(event).to_json和ActiveModelSerializers::SerializableResource.new(shop).to_json传递给请求：

let(:event) { create(:unpublished_event, country: country, language: language) }
let(:valid_params) do
  {
    shop: ActiveModelSerializers::SerializableResource.new(shop),
    event: ActiveModelSerializers::SerializableResource.new(event)
  }.to_json
end

expect {
      post "/shops/#{shop.id}/events", params: valid_params, headers: headers
}.to change(shop.events, :count).by(1)

但是失败了：

ActiveModelSerializers::Adapter::JsonApi::Deserialization::InvalidDocument:
Invalid payload ({:data=>"Expected hash"}): ...

如果我通过在每个模型上添加valid_params来更改to_json：

let(:valid_params) do
 {
    shop: ActiveModelSerializers::SerializableResource.new(shop).to_json,
    event: ActiveModelSerializers::SerializableResource.new(event).to_json
 }
end

它也不起作用，并因另一个解析错误而失败：

ActionDispatch::Http::Parameters::ParseError:
       765: unexpected token at 'shop=%7B%22data%22%3A%7B%2....

以下是创建时发布的内容：

Parameters: {"data"=>{"relationships"=>{"shop"=>{"data"=>{"type"=>"shops", "id"=>"613"}}, "event"=>{"data"=>{"type"=>"events", "id"=>"46"}}}, "type"=>"shop-events"}, "shop_id"=>"613"}

ShopEventsController具有strong_params的定义如下：

def shop_event_params
      ActiveModelSerializers::Deserialization.jsonapi_parse!(params,
        only: [
          :shop,
          :event
        ])
    end

和shop_event_params仅返回2个ID：

shop_event_params: {:shop_id=>"613", :event_id=>"46"}

这是怎么了？谢谢。
