==  AddRedirectionsModel: migrating ===========================================
-- create_table(:redirections)
NOTICE:  CREATE TABLE will create implicit sequence "redirections_id_seq" for serial column "redirections.id"
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "redirections_pkey" for table "redirections"
   -> 0.2534s
Creating shortened URL for existing contents, this may take a moment
rake aborted!
An error has occurred, this and all later migrations canceled:

The single-table inheritance mechanism failed to locate the subclass: 'Page'. This error is raised because the column 'type' is reserved for storing the class in case of inheritance. Please rename this column if you didn't intend it to be used for storing the inheritance class or overwrite Content.inheritance_column to use another column for that information.

(See full trace by running task with --trace)
