Rails: Querying a field that contains array

Question

Created a table clients using Postgres database having an order_ids field which is an array field ( array: true ). I want to fetch only those clients whose order_ids field contains value '220'.

Example: order_ids contains ["12","13","220"] . So, in where clause I want to do something like this:

Client.where("order_ids contains(?)",220)

Any idea?

Answer 1

Client.where("220 = ANY(order_ids)")

Answer 2

Have you try like this :

Client.where("? = ANY(order_ids)", 220)

Or

Client.where("order_ids @> ?", '{202}')

or

Client.where("? = ANY(order_ids)", '{220}')
