如何在控制器中添加屬性到rails params並傳遞到不同的控制器

Question

upload_controller 
def create 
    file = @upload.file 
    content = File.read file 
    params['content'] = content 
end 
end 

這裏params['content']有適當的文件內容。

book_controller 
def create 
    @book.description = params['content'] 
    @book.save 
end 
end 

但params['content']在book_controller.rb回報nil

如何傳遞從上傳內容控制器預訂控制器？

Answer 1

可能這項工作

content = File.read file 
    redirect_to url_you_want_to_redirect(content: content)
