刚添加了使用gem s3_direct_upload直接上传到Amazon S3的功能.
不幸的是,现在它没有处理我喜欢的额外图像大小调整.
:styles => { :thumbnail => "200x200#" }
查看文档后,我无法找到任何涉及此问题的内容.我还使用本教程来正确设置每个设置.如何让图像样式与Direct_upload一起使用？

User Load (1.0ms) SELECT "users".* FROM "users" WHERE "users"."id" = 29 ORDER BY "users"."id" ASC LIMIT 1
(0.3ms) BEGIN
Update Exists (0.5ms) SELECT 1 AS one FROM "updates" WHERE "updates"."id" = 730128 ORDER BY created_at DESC LIMIT 1
SQL (12.2ms) INSERT INTO "updates" ("created_at", "description", "direct_upload_url", …这是我的哈希:
{"graph"=>[{"1"=>16, "2"=>44, "3"=>53, "4"=>53, "5"=>80, "6"=>71, "7"=>63, "8"=>54, "9"=>53, "10"=>44, "11"=>76, "12"=>82, "13"=>66, "14"=>59, "15"=>64, "16"=>39, "17"=>19, "18"=>14, "19"=>5, "20"=>6, "21"=>5, "22"=>7, "23"=>6, "24"=>7}]}
我正在尝试获取每个值并将它们加在一起.长而不正确的方法是获取每个值并将它们添加到一起如下:
first_number = json["graph"][0]["1"]
second_number = json["graph"][0]["2"]
如何简化此计算以获得总计数？
