rails_admin: error when searching on a model with no name field

I posted this problem on the email list, and @bbenezech suggested i make a ticket.

I have a model that does not have a name field. I have it under rails_admin with the default config-- it’s listed in “included_models” and does not have any custom configuration.

When I try to do a search on my other models, it works as expected.

When I try to do a search on this one model, I get the bellow error. this is the only model that does not have a “name” column, hence my guess that that is the culprit. I haven’t dug very deep into the rails_admin code to chase this.

undefined method `name' for nil:NilClass

{"sort_reverse"=>"false",
 "utf8"=>"✓",
 "model_name"=>"email_addresses",
 "sort"=>"id",
 "query"=>"consumer"}
