Search over a nested / multi-level Postgres JSON type using Active Record

Question

Suppose I have the json object below

:response_body => {
    \"status\" => \"ok\",
    \"um\" => {
        \"a\" => \"a\",
        \"b\" => {
         


        

Answer 1

If you are using the Postgres as database and the column really is a json type, you can use a search in Rails like this:

LogService.where("response_body#>>'{status}' = 'ok'")

This #>> will walk over the json path and make the search. If you use only #> (with just one >), it will return the remaing json.

Another example, if you want to get the "c" => "ok"

LogService.where("response_body#>>'{um, b, c}' = 'ok'")

I think that´s it.
