Using Ruby Driver to create a complicated query in Rethinkdb's Reql -

-

i using ruby driver rethink db , running problem nested elements has arrays.

i have data structured this

[{"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"},     ]}]

the desired result return row has 'profile_url' link ends "12345". using mix of ruby , javascript, have attempted :

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

however, still not returning result, there clear way use ruby driver???

the desired result be

[{"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"},     ]}]

please , in advance!!! :d

i think want:

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