Re: [typo] db migrate failure in new 6.0.5 Matijs van Zuijlen Tue Jul 05 03:00:34 2011

Hi Alan,

Sadly, this is a known bug :-(. I'm working on an overhaul of the migrations, many of which were created in prehistory, but I'll try to rush a fix for this particular problem today.

In the mean time, you can take a look at


The patch there apparently works (though I have not tested it myself), but DO be sure to remove it once the migration is done.

An error has occurred, 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.

Tasks: TOP =>  db:migrate
(See full trace by running task with --trace)


What am I missing?  I can't imagine there is/was a problem with the
database as I'm staring with a fresh empty database.  Any thoughts?
