FOS Elastica -- getting string representation of query

Question

I am unit-testing a repository that uses FOS Elastica and I was wondering if anyone knows how to get the string version of a query, rather than in array form. Here is my repository method:

    /**
     * Creates query object by either first or last name, with given parameters
     *
     * @param $name
     *
     * @param array $params
     *
     * @return Query
     */
    public function findByFirstOrLast($name, array $params)
    {
        $queryString = new QueryString();
        $queryString->setQuery($name);
        $queryString->setFields(array('firstName', 'lastName'));


        $query = new Query();
        $query->setQuery($queryString);
        $query->setSort(array($params['sort'] => array('order' => $params['direction'])));

        return $query;
    }

Assuming $name = 'foo'; (and that I am sorting on id), I believe the corresponding FOS Elastica query should be

{
    "query":
    {
        "query_string":
            {
                "query":
                    "foo",
                    "fields":["firstName","lastName"]
            }
    },
    "sort":
    {
      "id":
          {
              "order":"asc"
          }
    }
}

Does anyone know how to get this json-string representation of the query? It doesn't necessarily have to be in this pretty format either, it can be a one-line string.

Answer 1

I see you no longer are using this but I ended up needing the same thing.

Right before return $query you can use json_encode($query->getQuery()->toArray()) and that should give you what you need as a single line string.
