[英]Form to submit file to controller upload action in rails
控制器:
class SongsController < ApplicationController
.
.
.
def upload
bucket = find_bucket
file = params[:file] edit: previously was file = :file
if bucket
AWS::S3::S3Object.store(file, open(file), bucket)
redirect_to root_path
else
render text: "Couldn't upload"
end
end
private
.
.
.
def find_bucket
AWS::S3::Bucket.find('kanesmusic')
end
end
在索引視圖中上傳表單:
<h2>Upload a new MP3:</h2>
<%= form_tag upload_path, :method => "post", :multipart => true do %>
<%= file_field_tag :file %>
<%= submit_tag "Upload" %>
<% end %>
錯誤(已編輯):
TypeError in SongsController#upload...can't convert AWS::S3::Bucket into String
我正在嘗試創建可以從用戶硬盤驅動器中選擇文件並上傳的表格。
您需要使用參數。 存放所有變量的位置。
像這樣:
params[:file]
但是對於使用文件上傳 (略有不同),請查看文檔
