ruby on rails 把阿里云上的图片资源转移到七牛云上写的一个task 文件 自动转移

先写下关于转移时，配置文件的修改

1 Gemfile中增加

gem 'carrierwave-qiniu'
gem 'qiniu-rs'

2 增加文件 config文件下qiniu-rs.rb

Qiniu::RS.establish_connection! :access_key => 'key',
:secret_key => 'key'

3 avatar_upload.rb中

storage :file 改为 storage :qiniu

4 carrierwave.rb文件中增加

config.storage = :qiniu
config.qiniu_access_key = "key"
config.qiniu_secret_key = "key"
config.qiniu_bucket = " "
config.qiniu_bucket_domain = " "
config.qiniu_block_size = 4*1024*1024
config.qiniu_protocal = "http"

这样配置文件就改好了

接下来就是task 文件了

require 'rake'

namespace :utils do

desc "Deploy all picture in local to QiuNiuCloud"
task :deploy_picture_to_qiniu => :environment do
@coy = Company.all
@tech = Technician.all
@ve = Venue.all
@sm = ServiceMenu.all
@pic = Pic.all
modified_by_shell
upload_to_qiniu(@coy,1)
upload_to_qiniu(@tech,1)
upload_to_qiniu(@ve,1)
upload_to_qiniu(@sm,1)
upload_to_qiniu(@pic,2)
end

desc "update_gemfile"
task :update_gemfile => :environment do
url = Rails.root.to_s+"/Gemfile"
context = "gem \"qiniu-rs\" \\n gem \"carrierwave-qiniu\"" #\\转义符号
`sed -i '4 i #{context}' #{url}`  #ruby中用``执行shell脚本
end
end

def upload_to_qiniu(ava,a)
case a

if !ava.nil?
ava.each do |t|

else

end
end
end
