i want to insert data to a model through xml file.There is a many2 one field.My condition is the data should be inserted according to the name i.e sms gateway in the model gateway_setup.How Could i achieve this..?

<field name="gateway_id" eval="obj(ref('kw_sendsms.model_gateway_setup')).name=='sms_gateway'" model="gateway_setup"/>

The above code gives odoo.tools.convert.ParseError: "Record does not exist or has been deleted.

But in my model the name 'sms_gateway' is already present.

i think the code may be wrong.

Could anyone please help me to find out the solution..?
