Using Odoo External API, is it possible to filter by a field that is equal to array of values?

Question

I know how to filter by value , but I don't know how to filter by array of values (ie the field that the filter is applied to contains array).
I use Odoo 15.0 and XML-RPC to get external access to its database.
In this doc I found out how to get records filtered by a value :

XmlRpcClient client = new XmlRpcClient();
XmlRpcClientConfigImpl common_config = new XmlRpcClientConfigImpl();
String path = "https://my-domain.odoo.com";
common_config.setServerURL(new URL(String.format("%s/xmlrpc/2/common", path)));
int uid = (int) client.execute(common_config, "authenticate", 
        asList(db_name, login, password, emptyMap()));

final XmlRpcClient models = new XmlRpcClient() {{
    setConfig(new XmlRpcClientConfigImpl() {{
        setServerURL(new URL(String.format("%s/xmlrpc/2/object", path)));
    }});
}};

List<Object>listProds = asList((Object[]) models.execute("execute_kw", asList(
    db_name, uid, password,
    "product.pricelist.item", "search_read",
    asList(asList(
        asList("fixed_price", "=", 0.09) // <-- filter setting
    )),
    new HashMap() {{
        put("fields", asList(
            "id", "pricelist_id", "fixed_price", "name"
        ));
        put("limit", 300);
    }}
)));
System.out.println("Read some fields for the products: " + listProds2);

For instance, using the code above I get all rows with fixed_price = 0.09 :

But I need to filter by pricelist_id equals [2, Catalogue Price (CAD)] , which is String representation of Object[] . The value is an array itself, and here I'm stuck.
I tried different variants of filter syntax but none of them worked.

asList("pricelist_id", "=", asList(2, "Catalogue Price (CAD)")) 
// or
asList("pricelist_id", "=", new Object[] {2, "Catalogue Price (CAD)"}) 

give

psycopg2.errors.InvalidTextRepresentation: invalid input syntax for type integer: "%Catalogue Price (CAD)%" LINE 1: ...ND ("product_pricelist_item"."pricelist_id" in (2,'%Catalogu...

And the following variants of syntax have no effect as if the filter is absent:

asList("pricelist_id", "=", (new Object[]{2, "Catalogue Price (CAD)"}).toString())

asList("pricelist_id", "like", "%Catalogue Price (CAD)%")

asList("pricelist_id", "=", "2, Catalogue Price (CAD)")

asList("pricelist_id", "=", "[2, Catalogue Price (CAD)]")

It would be fine to filter by pricelist_id containing "Catalogue Price (CAD)" (one of the array values is enough because they are unique).

Answer 1

By default, Odoo will return (record id, record display_name) when reading a many2one field

To filter the result using a many2one field, you need to use the database id ( 2 ), example:

("pricelist_id", "=", 2)

You can also filter by a list of price list ids using the in operator:

("pricelist_id", "in", list_of_ids )
