Environment is REE(2011.12) on rvm, rspec 2.8.0, rails 3.0.6, and pg 0.13.2. Using PostgreSQL 8.3.17 on CentOS 5.6. The db:migrate have work correctly. But rspec have got follow
This usually happens when you have rspec running while migrating (usually via guard). A simple solution is to quit guard, do the migration and restart guard.
It typically indicates that there is another open PostgreSql connection. To bubble up the right error try % rake db:test:prepare
Running test prepare showed the following below and when the open connection (PGAdmin in my case) was closed the issue was resolved.
rake aborted!
PG::Error: ERROR: database "xyz_test" is being accessed by other users
DETAIL: There are 1 other session(s) using the database.
: DROP DATABASE IF EXISTS "xyz_test"
Tasks: TOP => db:test:load => db:test:purge
(See full trace by running task with --trace)
I've run into this in two instances (updated 6/13/2012):
I haven't yet migrated my test database...
rake db:migrate
...which you need to do before both db:test:prepare
and db:test:load
.
When you invoke rspec it should prepare
and load
your database for you anyway. You shouldn't have to do that by hand.
A typo in my migration. I accidentally reversed my table and column names in the parameter list.
A migration on a Rails 3.1 project:
def change
add_column :had_import_errors, :studies, :boolean, :default => false
add_column :import_data_cache, :studies, :text
end
...which is wrong, because has_import_errors
and import_data_cache
are my column names, and they therefore should come second, not first.
The correct migration, with the table name first was:
def change
add_column :studies, :had_import_errors, :boolean, :default => false
add_column :studies, :import_data_cache, :text
end
Just hit this same error, nothing worked but dropping and re-creating the database, this fixed it for me.
rake db:drop db:create db:migrate
