Mailboxer: cannot destroy object

Question

I am trying to destroy an object within my ROR app.

But I get the following error:

ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR:  relation "mailboxer_conversation_opt_outs" does not exist
LINE 5:                WHERE a.attrelid = '"mailboxer_conversation_o...

I'm guessing this is related to this mailboxer_conversation_opt_outs table I don't have within my app.

I'm using Rails 4.2 and:

mailboxer (0.13.0)
  carrierwave (>= 0.5.8)
  foreigner (>= 0.9.1)
  rails (>= 3.2.0)

Is there a migration file I somehow missed?

Anyway, how come my object is connected to this table while the actual object cannot send messages?

Thanks

Answer 1

Yes, see itsnikolay's answer and the Upgrading section of the documentation.

Anyway, how come my object is connected to this table while the actual object cannot send messages?

Your Model class is probably still calling the acts_as_messageable method, which includes the Mailboxer::Models::Messageable Module into your ActiveRecord class, which declares several extra associations on your model. If you don't care about upgrading Mailboxer and just want to disconnect your model from Mailboxer entirely, just delete the acts_as_messageable line and you should be able to destroy your records without any more failed association issues.

Answer 2

It looks like you use previous version of Mailboxer.

Try to migrate on new one:

$ rails generate mailboxer:namespacing_compatibility
$ rails generate mailboxer:install -s
$ rake db:migrate
