我有一个 ruby 应用程序，它连接到 SQL 服务器（工作正常）和 Postgres（中断）。我不知道如何调试这个。我尝试从命令行连接到 postgres 数据库并且它工作（实际上没有密码）。
ActiveRecord::ConnectionNotEstablished它在第一行引发错误：
nti_shipment.line_items.each_with_index do |nti_line_item,i|
#logger.info "\n\nadd line item to shipto: "+nti_line_item.botcode+"****"
product = Web::Product.find_by_nti_product_id(nti_line_item.botcode)
#is_message = (i > 0 && (not product)) ? true : false
is_message = (nti_line_item.productid == 0) ? true : false
if !(is_message)
web_line_item = web_shipment.add_line_item(nti_line_item)
last_item = web_line_item
nti_line_item.itemid = web_line_item.id
nti_line_item.save!
elsif i > 0
last_item.line_item_messages << Web::LineItemMessage.add(last_item,nti_line_item)
end
end
这是我正在使用的 database.yml 文件：
production:
adapter: postgresql
database: mysite_production
username: myuser
password: "password"
options: "-o sslmode=require"
host: localhost
这是完整的跟踪：
