Hello
In my migration, I created index as follows:
def self.up
add_index :users, :facebook_id
add_index :references, [:referencing_user_id, :created_at]
…
and
def self.down
remove_index :users, :facebook_id
remove_index :references, [:referencing_user_id, :created_at]
working fine when creating …
== 7 AddIndexes: migrating
– add_index(:users, :facebook_id)
-> 0.0067s
– add_index(:references, [:referencing_user_id, :created_at])
-> 0.0063s
but when reverting , I get an error :
== 7 AddIndexes: reverting
– remove_index(:users, :facebook_id)
-> 0.0485s
– remove_index(:references, :referencing_user_id)
rake aborted!
Mysql::Error: #42000You have an error in your SQL syntax; check the
manual that corresponds to your MySQL server version for the right
syntax to use near ‘references’ at line 1: DROP INDEX
index_references_on_referencing_user_id
ON references
the generated sql is :
DROP INDEX index_references_on_referencing_user_id_and_created_at
ON REFERENCES
which doesn’t work at all !!! 42000 is a syntax error !!!
why, the index has been created, … how can I delete it ? is it a
rails’ bug ? (using 2.0)
thanks
