Migrations schema_info table, Rails Recipes Bug?

I have the rails recipes book and i was going through the migrations
recipe. Everything seemed to work except for the last part in trying to
do
a rake migrate with a migration file version 1 and the schema_info
version
set to 0. Without the force attribute, the rake migration fails, as
expected.

So the recipe says to run this:

ruby script/runner ‘ActiveRecord::Base.connection.execute(“INSERT INTO
schema_info (version) VALUES(1)”)’

with an INSERT function. however, it said the schema_info table is just
1
column, 1 row. Is this true? Cause if that is true, shouldnt the
command
be to “UPDATE” the version to 1, not inserting another row?

I guess my confusion lies in the definition of schema_info. I think it
makes sense to be just one column, one row, but i’m just a simple minded
programmer.

But anyway, my rake migrations kept failing until i switched to the
update
command:

ruby script/runner ‘ActiveRecord::Base.connection.execute(“UPDATE
schema_info SET version=1”)’

I know its a beta book, so i’m looking to confirm if this is a bug or
not.

Thanks.

Thanks, Manish. I think you’re right. I need to go back through and
make sure that this follows the same flow that I did in the Recipe.
Your comments are appreciated!

I had this very same prob today, but there was some mention on the
user-submitted errata of deleting the 0 (leaving just the 1) – which I
did and this solved the prob., and I’ve since done another migration
without any probs, so that seems the prob.
