Question

尝试将我的MYSQL数据库转换为postgreSQL，以便它可以很好地与heroku一起使用。我安装了gem mysql2psql并运行它。当我运行它时，我得到......

mysql2psql
Creating table breads...
Created table breads
Creating table sammiches...
Created table sammiches
Creating table schema_migrations...
Created table schema_migrations
Counting rows of breads... 
Rows counted
Loading breads...

33 rows loaded in 0min 0s
Counting rows of sammiches... 
Rows counted
Loading sammiches...

161 rows loaded in 0min 0s
Counting rows of schema_migrations... 
Rows counted
Loading schema_migrations...

4 rows loaded in 0min 0s
Indexing table breads...
Indexed table breads
Indexing table sammiches...
Indexed table sammiches
Indexing table schema_migrations...
Indexed table schema_migrations
Table creation 0 min, loading 0 min, indexing 0 min, total 0 min

如果我在pg：psql我可以运行查询，我知道列正确导入到表中，但是没有条目......

我试过了 -

heroku rake db:migrate
WARNING: `heroku rake` has been deprecated. Please use `heroku run rake` instead.
Running `rake db:migrate` attached to terminal... up, run.6669

但它仍然是空的。清空likeeeee

dbl77pdgmr9l10=> select * from sammiches;                                                                                                                        id | name | image | country | description | created_at | updated_at 
----+------+-------+---------+-------------+------------+------------
(0 rows)

# if tables is given, only the listed tables will be converted.  leave empty to convert all tables.
#tables:
#- table1
#- table2
# if exclude_tables is given, exclude the listed tables from the conversion.
#exclude_tables:

# if supress_data is true, only the schema definition will be exported/migrated, and not the data
supress_data: false

# if supress_ddl is true, only the data will be exported/imported, and not the schema
supress_ddl: false

# if force_truncate is true, forces a table truncate before table loading
force_truncate: false

Answer 1

检查您的database.yaml配置

suppress_data: true

可能不会移动数据，只能移动架构
