Does not work with models with `.` in table name

[westonganger]

In some of my Rails apps I connect to multiple databases. In that way I define my models like so:

class Project < OtherDatabaseModels
  self.table_name = "other_db.projects"
end

It is outputting the following error in the file after running the annotations

# Could not dump table "other_db.projects" because of following NoMethodError
#   undefined method `[]' for nil:NilClass

The error is for having the . in the table name. Its not related not to using the second database.
