Tengo una aplicación que usa postgres endesarrollo y producción. Recientemente empujé a Heroku y todo estaba funcionando bien. Pude extraer la base de datos de heroku y volver a subir sin problemas. Hoy, sin embargo, intenté quitar la base de datos de heroku y recibí este error

heroku db:pull

Loaded Taps v0.3.24
Auto-detected local database: postgres://postgres:a@127.0.0.1/app_development?encoding=utf8
Warning: Data in the database "postgres://postgres:a@127.0.0.1/app_development?encoding=utf8" will be overwritten and will not be recoverable.

Unable to fetch tables information from http://heroku:osui59a24am79x@taps19.heroku.com. Please check the server log.

Entonces corro heroku logs después:

No tengo idea de dónde buscar una solución, así que espero que alguien pueda ayudar. Acabo de empezar a aprender los rieles, así que recuerda esto cuando trates de ayudar.

Gracias por adelantado.

EDITAR:

He intentado todo tipo: reinstalar heroku, grifos. rehice mi aplicación y empuje a heroku. reinstalado postgres.

Nada parece funcionar. ¡Volviéndome loco!

3 para la respuesta № 1

Encontré algún tipo de solución.
Tengo el mismo problema con mi SHARED_DATABASE en heroku
rubí 1.9.2
gemas:
pg (0.11.0)
heroku (2.32.4)
heroku-api (0.3.5)
grifos (0.3.24)
heroku db: pull terminó con:
No se puede obtener información de tablas de http://...@taps19.heroku.com. Por favor revise el registro del servidor.

Cambié a Ruby 1.8.7 usando rvm y heroku db: pull funciona bien.
Volver de nuevo a ruby ​​1.9.2 para desarrollar mi aplicación.

Espero que esto ayude a alguien hasta que db: pull se arregle con ruby ​​1.9.2.

Acabo de recibir una respuesta de heroku. Dijeron que estaban teniendo algunos problemas con los grifos y que ahora está funcionando nuevamente.

Lo comprobé y confirmo que está funcionando para mí.

(Las instrucciones para PostgreSQL están más abajo en la página)

Una solución temporal sería volcar directamente los datos de su servidor de base de datos y cargarlos manualmente usted mismo. Tengo ambas bases de datos (en Heroku y localmente) en MySQL, así que hice:

1. mysqldump -h host -P port_number -u user_name_to_your_db -p your_db_name > data.sql

Una vez que ejecute el comando anterior con los detalles correctos, se le pedirá que ingrese su contraseña.

NOTA: Nunca ponga su contraseña en su comando de shell ya que se está almacenando en el historial de comandos de shell.

Conseguir su username, password, your_db_name, host y port_number de la configuración de Heroku:

2. heroku config --app your-app-name | grep DATABASE_URL

Tu DATABASE_URL se verá así:

mysql2://username:password@host:port_number/your_db_name

Un ejemplo de un poco más real. DATABASE_URL se verá así (los detalles de inicio de sesión están modificados):

mysql2://afdgsdfghliue:ESIJAFDG-sAFsgiags3464@ec2-34-15-23-232.compute-2.amazonaws.com:5432/9twgsenr8543

En ese caso, los detalles serían respectivamente (recuerde, estos son falsos):

username: afdgsdfghliue:ESIJAFDG
password: ESIJAFDG-sAFsgiags3464
host:     ec2-34-15-23-232.compute-2.amazonaws.com
port:     5432
database: 9twgsenr8543

Cuando corres el mysqldump con detalles correctos como se muestra en 1. tendrás tus datos almacenados en data.sql localmente. Ahora para cargarlo en su base de datos local (todavía estamos hablando de MySQL) deberá ejecutar:

mysql -u your_local_db_username -h 127.0.0.1 -p your_local_db_name < data.sql

Los detalles de inicio de sesión de la base de datos local que debe tener.

PostgreSQL

No he comprobado las instrucciones a continuación, así que úselas junto con su cerebro ;-)

Lo encontré desde

pg_dump --help

que podría ejecutar comandos similares para volcar su base de datos PostgreSQL de Heroku de esta manera:

pg_dump -h host -p port -U username -W your_db_name > data.sql

Tu DATABASE_URL comenzará con postgres:

postgres://username:password@host:port_number/your_db_name

Residencia en

psql --help

Aquí es cómo cargar su base de datos PostgreSQL local desde el data.sql archivo preparado anteriormente:

psql -h 127.0.0.1 -U your_local_db_username -W -d your_local_db_name -f data.sql

Un poco de proceso manual, pero al menos te pone en marcha.
