It appears that DataMapper.auto_upgrade! is attempting to re-create the columns of a base STI model, for every descendent of that base model. This results in duplicate column errors when calling auto_upgrade!. This error does not occurr when running DataMapper.auto_migrate!.

I did some research into this test today, but I haven’t been able to narrow down the cause. I think it’s something inside DO or SQLite causing the problem. Here’s what I do know:

  • The path to the file in the example is not writable on most systems, so SQLite defaults to using an in-memory database. If you specify "sqlite::memory:" you will see the same bug.
  • If you change the path to a writable location, a file will be created, and the bug will not occur.
  • A CREATE TABLE statement is issued, creating the table, then a PRAGMA table_info query runs immediately after and returns no records. That means that the columns created are not seen by the system.
  • Performing an ALTER TABLE statement and adding in a column that already exists will cause an explosion. So even though SQLite does not report any columns in the table, it won’t allow you to add them.
  • At first I thought it was a problem with pooling, like maybe one connection would create the table, and the other connection wouldn’t see it, because of how in-memory DBs are not sharable across connections. However, I checked the object_id of the Connection objects both when the CREATE TABLE and PRAGMA queries were executed, and they were the same.

At this point I am unsure what the solution is. I think this will require more research, so I am removing it from the 1.0.0 milestone.

@dirkjan: Can you think of anything that would cause this behaviour?

I'm getting this issue too.

1.9.2-p290
dm-core 1.2.0
dm-migrations 1.2.0

/Users/darren/.rbenv/versions/1.9.2-p290/lib/ruby/gems/1.9.1/gems/dm-migrations-1.2.0/lib/dm-migrations/adapters/dm-do-adapter.rb:70:in `execute_non_query': duplicate column name: id (DataObjects::SyntaxError)

Same deal as you, auto_migrate! works.

I was able to work around this issue with this
DataMapper::Model.descendants.each {|m| m.auto_upgrade! if m.superclass == Object}

as a replacement for DataMapper.auto_upgrade!

I'm getting the same issue. It's especially annoying when adding a new index, since it tries to add it twice.

It also seems to happen with DataMapper.auto_migrate! as well:

require 'rubygems'
require 'dm-core'
require 'dm-migrations'

DataMapper::Logger.new($stdout, :debug)
DataMapper.setup(:default, 'sqlite::memory:')

class Shape
  include DataMapper::Resource

  property :id,    Serial
  property :type,  Discriminator
  property :name,  String, :index => true

end

class Circle < Shape
end

DataMapper.finalize
DataMapper.auto_migrate!

When fresh it runs correctly, but the tables are being created twice:

 ~ (0.000048) SELECT sqlite_version(*)
 ~ (0.000097) DROP TABLE IF EXISTS "shapes"
 ~ (0.000011) PRAGMA table_info("shapes")
 ~ (0.000426) CREATE TABLE "shapes" ("id" INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, "type" VARCHAR NOT NULL, "name" VARCHAR(50))
 ~ (0.000129) CREATE INDEX "index_shapes_name" ON "shapes" ("name")
 ~ (0.000163) DROP TABLE IF EXISTS "shapes"
 ~ (0.000009) PRAGMA table_info("shapes")
 ~ (0.000144) CREATE TABLE "shapes" ("id" INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, "type" VARCHAR NOT NULL, "name" VARCHAR(50))
 ~ (0.000123) CREATE INDEX "index_shapes_name" ON "shapes" ("name")

However, if the table already exists and I run auto_upgrade! instead, I get a duplicate column name error when it tries to add the index the second time.

I'm using data_mapper (1.2.0).

Thanks for the workaround @charlieschwabacher
