ruby-on-rails - PG::UndefinedTable：错误：关系“房间”不存在

Question

我刚刚从 Sqlite3-local 迁移到 heroku 上的 Postgresql。我的一个工作正常的视图现在显示以下错误：

PG::UndefinedTable: ERROR: relation "rooms" does not exist LINE 8: WHERE a.attrelid = '"rooms"'::regclass ^ : SELECT a.attname, format_type(a.atttypid, a.atttypmod), pg_get_expr(d.adbin, d.adrelid), a.attnotnull, a.atttypid, a.atttypmod, c.collname, col_description(a.attrelid, a.attnum) AS comment FROM pg_attribute a LEFT JOIN pg_attrdef d ON a.attrelid = d.adrelid AND a.attnum = d.adnum LEFT JOIN pg_type t ON a.atttypid = t.oid LEFT JOIN pg_collation c ON a.attcollation = c.oid AND a.attcollation <> t.typcollation WHERE a.attrelid = '"rooms"'::regclass AND a.attnum > 0 AND NOT a.attisdropped ORDER BY a.attnum

控制器很简单：

def index
@rooms = Room.all
end

控制台显示以下内容：

ActiveRecord::StatementInvalid (PG::UndefinedTable: ERROR:  relation "rooms" does not exist)
LINE 1: SELECT  "rooms".* FROM "rooms" LIMIT $1
                               ^
: SELECT  "rooms".* FROM "rooms" LIMIT $1

房间表在数据库中，事件包含一些虚拟数据。请问有人熟悉这个问题吗？谢谢。
