我在Interbase中有一个数据库,我想使用ActiveRecord直接从我的Rails应用程序访问它.我该怎么做?
我已经使用http://guides.rubyonrails.org/i18n.html中指定的指令 来翻译我的模型的字段,但标签没有翻译.我做错了什么.
我有一个User该领域的模型,name我想把它翻译成巴西葡萄牙语(pt_br),所以我得到了我的pt_br.yml:
pt_br:
errors: "Erro!"

user: "Usuário"

name: "Nome"
address: "Endereço"

我在 Rails 应用程序中有几个带有外键约束的表。例如,每个订单都属于一个客户。订单表中有一个costumer_id列。
当我删除已下订单的客户时,由于数据库限制,MySQL 返回错误:
Mysql::Error: 无法删除或更新父行:外键约束失败 (
orders, CONSTRAINTorders_ibfk_2FOREIGN KEY (customer_id) REFERENCEScustomers(id))
屏幕上弹出丑陋的错误,所有堆栈跟踪和那些 ActiveRecord::StatementInvalid 在 DevicesController#destroy ...
我想知道是否有一种优雅的方法来处理这些约束错误,比如“你可以删除这个对象,因为它与 X 相关联”
我怎么能做到?
有没有办法在Android上运行echoprint-codegen或者是否有Java实现?
Eithop上的Echoprint codegen:https://github.com/echonest/echoprint-codegen
有一个C++实现吗?我只是无法弄清楚如何将它移植到Java,以便我可以在Android设备上运行它,假设Android 2.2及以上.
有没有人下载过EchoPrint的iOS版演示版?这是一个音频指纹识别开源软件.
我刚刚下载了它,但似乎缺少框架......任何可以获得功能版本的地方?

我有一个应用程序可以执行很多 batchGets(主要是大约 2000 个键)。这是我使用的代码:
AerospikeClient aerospike = new AerospikeClient("10.0.240.2", port)
public byte[][] getBatch(byte[][] keys) {
Key[] aeroKeys = new Key[keys.length];
for (int i = 0; i < keys.length; i++) {
aeroKeys[i] = new Key(NAMESPACE, setName, keys[i]);
}
Record[] records = aerospike.get(batchPolicy, aeroKeys);
byte[][] response = new byte[keys.length][];
for (int i = 0; i < keys.length; i++) {
if (records[i] != null) {
response[i] = (byte[]) records[i].getValue(DEFAULT_BIN_NAME);

}
return response;
