rake db:test:prepare 不創建所有表

Question

注意：使用 Rails 3.0.7、Postgresql 8.4.4-1、rake 0.8.7。

試圖讓 Rails 測試工作。

命令 rake db:test:prepare 似乎工作正常——

$ rake db:test:prepare -t
(in /home/beau/looked)
** Invoke db:test:prepare (first_time)
** Invoke db:abort_if_pending_migrations (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:abort_if_pending_migrations
** Execute db:test:prepare
** Invoke db:test:load (first_time)
** Invoke db:test:purge (first_time)
** Invoke environment 
** Execute db:test:purge
** Execute db:test:load
** Invoke db:schema:load (first_time)
** Invoke environment 
** Execute db:schema:load
NOTICE:  CREATE TABLE will create implicit sequence "slugs_id_seq" for serial column "slugs.id"
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "slugs_pkey" for table "slugs"

但是有些表沒有被創建。

這些是“發展”表：

$ psql -d looked -U admin -c '\d'

               List of relations
 Schema |       Name        |   Type   | Owner 
--------+-------------------+----------+-------
 public | businesses        | table    | admin
 public | businesses_id_seq | sequence | admin
 public | categories        | table    | admin
 public | categories_id_seq | sequence | admin
 public | schema_migrations | table    | admin
 public | slugs             | table    | admin
 public | slugs_id_seq      | sequence | admin
(7 rows)

rake:db:prepare 為測試環境創建的表——

$ psql -d looked_test -U admin -c '\d'
               List of relations
 Schema |       Name        |   Type   | Owner
--------+-------------------+----------+-------
 public | categories        | table    | admin
 public | schema_migrations | table    | admin
 public | slugs             | table    | admin
 public | slugs_id_seq      | sequence | admin
(4 rows)

如您所見，它創建了一些表，但沒有創建企業、businesss_id_seq 或 categories_id_seq。

我不知道為什么，有人可以幫助我嗎？

首先確保在rake db:test:prepare之前運行rake db:migrate 。

如果這不起作用，請在某處備份您的schema.rb ，將其刪除，然后在運行rake db:test:prepare rake db:schema:dump 。 這將確保您的schema.rb文件完全反映您的數據庫。
