なんらかの nil エラーが発生しています。これは を呼び出していることnilを'name'示していますが、どこにあるかはわかりません。
ここに私のルートがあります：
# Mobile api
map.namespace :mobile_api do |api|
api.resources :updates, :only => [ :index ]
api.resources :checkouts, :collection => { :reading_progress => :put }
end
postman を使用して API 呼び出しをデバッグしています。
郵便配達員をRawとして、JSONをPUTURL
として送信するデータは次のlocalhost:3000/mobile_api/checkouts/reading_progressとおりです。
{"title":"Awesome post!", "tags": ["blue", "jeans"] }
JSON データを削除し、データなしでリクエストを行うと、コントローラに渡されます。
class MobileApi::CheckoutsController < ApplicationController
def reading_progress
binding.pry
end
end
送信するデータを郵便配達員に追加するとすぐに、次のエラーが発生します。
