Question

我正在使用ruby驱动程序来重新思考db并且我遇到了包含数组的嵌套元素的一些问题。

我的数据结构如下

[{"family_name"=>"Adam"},
 {"family_name"=>"Bobby"},
 {"family_name"=>"Crissy",
  "groups"=>
   [{"logo_url"=>"https://www.logourl.com/1111.png",
     "name"=>"Sample Name 1",
     "profile_url"=>"https://www.profileurl.com/groups?gid=1111"},
    {"logo_url"=>"https://www.logourl.com/2222.png",
     "name"=>"Sample Name 2",
     "profile_url"=>"https://www.profileurl.com/groups?gid=2222"},
    {"logo_url"=>"https://www.logourl.com/3333.png",
     "name"=>"Sample Name 3",
     "profile_url"=>"https://www.profileurl.com/groups?gid=3333"},
   ]},
 {"family_name"=>"Bobby"},
 {"family_name"=>"Hillton",
  "groups"=>
   [{"logo_url"=>"https://www.logourl.com/4444.png",
     "name"=>"Sample Name 1",
     "profile_url"=>"https://www.profileurl.com/groups?gid=4444"},
    {"logo_url"=>"https://www.logourl.com/5555.png",
     "name"=>"Sample Name 2",
     "profile_url"=>"https://www.profileurl.com/groups?gid=55555"},
    {"logo_url"=>"https://www.logourl.com/6666.png",
     "name"=>"Sample Name 3",
     "profile_url"=>"https://www.profileurl.com/groups?gid=12345"},
    ]}]

所需的结果是返回具有＆＃39; profile_url＆＃39;的行。链接以＆＃34; 12345＆＃34;结尾。使用Ruby和Javascript的混合，我试过这个：

'r.table("profiles").filter{ |row| row['groups'].contains(r.js('function(group) { return group('profile_url').match("12345$") }'))}.run(conn)'

然而，它仍然没有返回结果，是否有一个明确的方法与ruby驱动程序一起使用???

期望的结果是

[{"family_name"=>"Hillton",
  "groups"=>
   [{"logo_url"=>"https://www.logourl.com/4444.png",
     "name"=>"Sample Name 1",
     "profile_url"=>"https://www.profileurl.com/groups?gid=4444"},
    {"logo_url"=>"https://www.logourl.com/5555.png",
     "name"=>"Sample Name 2",
     "profile_url"=>"https://www.profileurl.com/groups?gid=55555"},
    {"logo_url"=>"https://www.logourl.com/6666.png",
     "name"=>"Sample Name 3",
     "profile_url"=>"https://www.profileurl.com/groups?gid=12345"},
    ]}]

请提前帮助和谢谢！：d

Answer 1

我认为这会做你想做的事情：

r.table('profiles').filter {|row|
  row['groups'].contains {|group|
    group['profile_url'].match('12345$')
  }
}

使用Ruby Driver在Rethinkdb的Reql
