Heroku "Lo sentimos, pero algo salió mal"

En primer lugar, soy bastante novato en rails/heroku, ¡así que perdona la felicidad con antelación!Heroku "Lo sentimos, pero algo salió mal"

Hice el tutorial Rails (http://guides.rubyonrails.org/getting_started.html) y generé una aplicación de "blog" similar a la de "post", la inserté en github y luego la inserté en heroku.

Mi aplicación funciona bien a nivel local, pero cuando intento ejecutarla en línea, tiene el mensaje "Lo sentimos, pero algo salió mal" en la fuente roja.

Aquí es los registros de Heroku:

En pocas palabras, f.name es un objeto que representa una entrada en la base de datos (por lo que es la mayor parte de la información para f)

El "indefinido el error del método `name '" me parece extraño, ya que funciona perfectamente a nivel local.

Mi hipótesis es que la base de datos no está vinculada correctamente entre heroku y mi aplicación. Sin embargo, no sé cómo puedo solucionar/controlar este problema.

Mi aplicación está utilizando la "base de datos compartida" de forma predeterminada en este momento.

¿Alguna pista sobre qué cheque? Algo que me perdí?

EDITAR 1: base de datos de migración. La tabla 'publicaciones' parece estar ya 'detectada'. Aquí hay un rastreo:

Lo más probable es que no hayas migrado tu base de datos. No estoy seguro si heroku toolchain se encarga de eso. –

si no te importa la producción de db puedes probar algo como 'heroku run rake db: drop' y luego ejecutar nuevamente tus migraciones en Heroku. –

Definitivamente parece un problema en la migración CreatePosts. Publicar eso? – MBHNYC

Resulta que mi base de datos en heroku estaba siendo referenciada incorrectamente. Esto es lo que hice: db

rastrillo: caída - esta matado a ambas tablas de prueba y desarrollo
re-creado las dos bases de datos en PosgreSQL lo tengo local, así
rastrillo db: migrate - por lo que en este punto localhost está trabajando nuevamente después de 1.
complementos heroku - compartida de base de datos se debe mostrar
heroku pg: restablecer SHARED_DATABASE - no puede hacer db: restablecer en heroku debido al permiso emite
heroku carrera de rake db: migrate - remigrar la producción db

Aunque solo los pasos 5 y 6 fueron los únicos que abordaron mi problema principal directamente.

Gracias a todos !!!

No tengo idea de lo que acabo de hacer, pero funcionó. ¡Gracias! – IIllIIll

Quizás quiso migrar su base de datos?

intente ejecutar:

heroku run rake db:migrate

del directorio de su proyecto.

Sí, pero obtengo algo como esto: PG :: Error: ERROR: la relación "publicaciones" ya existe (agregará trazas en la publicación original en breve) – mhz

Parece que tiene más de una migración para crear el modelo post. Vería las migraciones primero.

hmmmm, solo hay un archivo en db/migrate/... if eso es lo que quieres decir. El archivo está en EDIT 3 – mhz
