【问题描述】：
create_table "drugs", options: "ENGINE=InnoDB DEFAULT CHARSET=utf8", force: :cascade do |t|
t.integer "item_seq"
t.string "name"
t.string "short_description"
t.string "short_notice"
t.json "package_insert"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
我正在尝试更新我的模型Drug，如上所示。它有大约 50,000 行数据，我正在使用 ruby 代码使用从单独的 api 服务器获取的数据更新模型中的项目。
我要更新的列是package_insert，其类型为json。
我只是想更新package_insert(BAR_CODE, EDI_CODE) 的某些键。
我遇到的问题是我无法更新多行，因为它在对第一行执行提交后会引发错误。
ruby 代码如下所示。
require 'json'
require 'net/http'
require 'active_support/core_ext/hash'
for i in 1..501
response = Net::HTTP.get_response(URI.parse(ENV["API_SERVER"])).body
hashed_response = Hash.from_xml(response)
hashed_response['response']['body']['items']['item'].each do |item|
#select drug to be updated
drug_to_change = Drug.find_by(item_seq: item['ITEM_SEQ'])
unless drug_to_change.nil?
package = JSON.parse(drug_to_change.package_insert)
package['DRB_ITEM']['BAR_CODE'] = item['BAR_CODE']
if !item['EDI_CODE'].nil?
package['DRB_ITEM']['EDI_CODE'] = item['EDI_CODE']
end
drug_to_change.update(package_insert: package.to_json)
else
new_item = Drug.new
new_item.item_seq = item['ITEM_SEQ']
new_item.name = item['ITEM_NAME']
#update
a = Hash.new
a["DRB_ITEM"] = item
new_item.save
end
end
end

rails 控制台结果中的相同代码：

我猜这个问题是由于 mysql 提交时间太长。我该如何解决这个问题？提前致谢。
SHOW CREATE TABLE drugs;
【问题讨论】：
-
你能发布一个真实的
SHOW CREATE TABLE drugs输出吗？一些示例数据和预期结果请参见Why should I provide a Minimal Reproducible Example for a very simple SQL query?。同时调试 ruby on rails 以便您知道查询为 ActiveRecord 生成的“模糊”查询？如果您知道查询运行EXPLAIN query并在此处发布。
