When I try and run rake db:migrate, I get this error: rake aborted! uninitialized constant CreateUsers /Library/Ruby/Gems/1.8/gems/activesupport-2.0.2/lib/active\_support/ dependencies.rb:266:in `load_missing_constant' /Library/Ruby/Gems/1.8/gems/activesupport-2.0.2/lib/active_support/ dependencies.rb:453:in`const\_missing’ /Library/Ruby/Gems/1.8/gems/activesupport-2.0.2/lib/active\_support/ dependencies.rb:465:in `const_missing' /Library/Ruby/Gems/1.8/gems/activesupport-2.0.2/lib/active_support/ inflector.rb:257:in`constantize’ /Library/Ruby/Gems/1.8/gems/activesupport-2.0.2/lib/active\_support/ core\_ext/string/inflections.rb:148:in `constantize' /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active_record/ migration.rb:386:in`migration\_class’ /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active\_record/ migration.rb:363:in `migration_classes' /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active_record/ connection_adapters/sqlite_adapter.rb:351:in`inject’ /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active\_record/ migration.rb:359:in `each' /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active_record/ migration.rb:359:in`inject’ /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active\_record/ migration.rb:359:in `migration_classes' /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active_record/ migration.rb:339:in`migrate’ /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active\_record/ migration.rb:307:in `up' /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active_record/ migration.rb:298:in`migrate’ /Library/Ruby/Gems/1.8/gems/rails-2.0.2/lib/tasks/databases.rake:85 /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:546:in `call' /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:546:in`execute’ /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:541:in `each' /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:541:in`execute’ /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:508:in `invoke_with_call_chain' /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:501:in`synchronize’ /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:501:in `invoke_with_call_chain' /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:494:in`invoke’ /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:1931:in `invoke_task' /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:1909:in`top\_level’ /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:1909:in `each' /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:1909:in`top\_level’ /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:1948:in `standard_exception_handling' /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:1903:in`top\_level’ /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:1881:in `run' /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:1948:in`standard\_exception\_handling’ /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:1878:in `run' /Library/Ruby/Gems/1.8/gems/rake-0.8.1/bin/rake:31 /usr/bin/rake:19:in`load’ /usr/bin/rake:19 I have no idea what is going on.

Actually I missed one reference…fixed it. But now I’m getting this error: rake aborted! No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb) /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:2143:in `raw_load_rakefile' /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:1897:in`load\_rakefile’ /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:1948:in `standard_exception_handling' /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:1896:in`load\_rakefile’ /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:1880:in `run' /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:1948:in`standard\_exception\_handling’ /Library/Ruby/Gems/1.8/gems/rake-0.8.1/lib/rake.rb:1878:in `run' /Library/Ruby/Gems/1.8/gems/rake-0.8.1/bin/rake:31 /usr/bin/rake:19:in`load’ /usr/bin/rake:19 I’m staring at the Rakefile right now…don’t know what could be causing this. ---

_sigh_ nevermind again, the issue isn’t solved…still getting the same error. ---

Nope, I made sure to change the migrations file name too. ---

Mike C wrote: > When I try and run rake db:migrate, I get this error: > > rake aborted! > uninitialized constant CreateUsers If I had to guess, you had a migration named \_create\_users.rb which created a users table. You edited this migration to rename the table, but you left the name of the migration file the same. The only time I’ve seen this sort of error with migrations comes from having a migration file named differently than the migration class. Hope that helps.
