線static_controller.rb的31呼籲id你希望成爲一個ActiveRecord對象的東西，但其實nil期間。找出原因。

（該錯誤消息指出nil，不會過分ActiveRecord對象，僅具有紅寶石內部id字段，這始終是4爲nil）。

in static_controller.rb文件我hav包含空間電影的ID。 @header_movie = PAPERCLIP_STORAGE_PATH +「videos/header_movies /#{header_movie.id}/#{header_movie.header_movie_file_name}」 – manijain

在這種情況下，Rails似乎在抱怨'header_movie'（_not_'@ header_movie'）是'nil '。也許你從來沒有設置它？除非您可以將該方法發佈到static_controller.rb中，否則我無法再提供幫助。 – Chowlett

但一旦我加載歡迎頁面，然後我得到一些MIME類型錯誤與視頻文件格式相關。 .......就像這樣...... 不支持「text/html」的HTTP「Content-Type」。媒體資源http：// localhost：3000/videos/header_movies/1/big-buck-bunny_trailer.webm的加載失敗。 PLZ指南爲這一個。 – manijain
