So, I’m gonna jump into the migrations and patch the existing add_index calls to specify a :name => value for all of the existing indexes, so that migrations will actually work and leave me with a database that matches the one in production ….

Figuring out why I suddenly couldn’t build my test database was not exactly the way I meant to spend the last hour ….

Update

Changeset 4768 is responsible for all this. Apparently, to allow reverse parsing of the indexes from the index name. Not alltogether a bad goal, but it still breaks down migrations … (thanks to Devin for find this one)

And, I discovered another problem last night. Seems that all of my text fields have a default value of “empy_clob()” … not the function, but that actual string. Sort of trashes one’s assumptions about unset fields. Apparently (thanks Roy) this has been worked out in ticket 7344 and already applied to Edge. Some sort of thing that only applies to Oracle, because, of course, nobody tests Rails on Oracle, it’s all MySQL. And I can’t really look into the patch attached to the ticket, because I keep getting Trac errors. Shaping up to have been a lovely adventure …

update
Finally got through to the site, and worked out a monkey patch to fix this. For those of you who might be running with oracle, and can’t upgrade to Edge (gee, wonder why not) the patch is below. This is a temporary thing, given that the ticket is closed, and will hopefully be fixed in 1.2.2 …
[ruby]
class ActiveRecord::ConnectionAdapters::OracleColumn
attr_writer :default
end if defined? ActiveRecord::ConnectionAdapters::OracleColumn

class ActiveRecord::ConnectionAdapters::OracleAdapter
def quote(value, column = nil) #:nodoc:
if value && column && [:text, :binary].include?(column.type)
%Q{empty_#{ column.sql_type.downcase rescue ‘blob’ }()}
else
super
end
end

alias columns_orig columns
def columns(*a)
columns_orig(*a).each do |col|
col.default = nil if col.default =~ /^(null|empty_[bc]lob())$/i
end
end
end if defined? ActiveRecord::ConnectionAdapters::OracleAdapter
[/ruby]

This appears to do the trick … a dump of the test schema no longer defaults all of our text columns to “empty_clob()” and tests are again passing …
