I've tried in vain to get 0.10RC1 to work with Merb, as I get the
following error reported whenever a model is saved to the database:
(this is done through merb -i on a brand new merb-gen'd app with one
table - parents, with :id and :name. The code is ZIP'd and uploaded to
the Google group)
>> p = Parent.new(:name => "Andy")
=> #<Parent @id=nil @name="Andy">
>> p.save
~ (0.000403) SELECT "id" FROM "parents" WHERE "name" = 'Andy' ORDER
BY "id" LIMIT 1
~ parents.id may not be NULL (code: 19, sql state: , query: INSERT
INTO "parents" ("name") VALUES ('Andy'), uri: sqlite3://
sample_development.db)
DataObjects::IntegrityError: parents.id may not be NULL (code: 19, sql
state: , query: INSERT INTO "parents" ("name") VALUES ('Andy'), uri:
sqlite3://sample_development.db)

This is a very odd error, IMO, as it is complaining about the
IntegrityError for the database ID on an INSERT statement, which
doesn't make a great deal of sense to me. I saw a link to some steps
to get a merb app ready for 0.10RC1 -
http://sick.snusnu.info/2009/06/03/migrating-to-datamapper-0100
- that implies there are changes required, presumably in merb-
datamapper, but I'm not sure what. Is there going to be a revised merb-
datamapper gem out too to support 0.10RC1?
Thanks in advance for any help,
Andy
