问题描述
可能与此问题有关使用OPA MongoDB高级API的基本GROUP BY语句.
我希望能够检索名称"字段值包含给定字符串的文档列表.
I want to be able to retrieve a list of documents which "name" field value contains a given string.
这是我的文件清单:
{name: "Charles-Hugo"},{name: "Jean Pierre"},{name: "Pierre Dupont"},
{name: "Charles-Hugo"},{name: "Jean Pierre"},{name: "Pierre Dupont"},
我希望只能检索名称包含"Pierre"字符串的文档:Jean Pierre和Pierre Dupont.
I want to be able to only retrieve documents which name contains the "Pierre" string: Jean Pierre, and Pierre Dupont.
我知道MongoDB高级API不可能做到这一点.我已经研究了低级API函数，但是我不知道以安全的Opa类型检索文档的最简单方法是什么.
I know this isn't possible with the MongoDB high-level API.I've looked in the low-level API functions but I don't know what's the easiest way to retrieve my documents in safe Opa type.
我还要在查询中添加跳过/限制选项.
Also I'd like to add skip/limit options to my query.
有什么主意吗?
推荐答案
Opa中的DbGen自动化机制对此提供了支持:
The DbGen automation mechanism in Opa has support for this:
DbSet.iterator(/path/data[name =~ pattern])
