class CreateBallots < ActiveRecord::Migration
def change
create_table :ballots do |t|
t.references :user
t.references :score
t.references :election
t.string :key
t.timestamps
end
add_index :ballots, :user
add_index :ballots, :score
add_index :ballots, :election
end
end
结果是:
SQLite3::SQLException: table ballots has no column named user: CREATE INDEX "index_ballots_on_user" ON "ballots" ("user")/home/muhd/awesomevote/db/migrate/20130624024349_create_ballots.rb:10:in `change'
我以为
t.references
应该为我处理这个问题?
t.references :user
