new - No se puede migrar la base de datos después del andamio. Sección 2.2 Ruby on Rails Tutorial Michael Hartl
rails scaffold (3)
Estoy trabajando en el tutorial de Hartl ruby on rails (sección 2.2) y tengo problemas para migrar la base de datos. Todo parecía estar funcionando, y luego ejecuté los rails generate scaffold User name:string email:string
Después intenté ejecutar bundle exec rake db: migrate y obtuve el siguiente mensaje de error:
$ bundle exec rake db:migrate

== 20141125234257 CreateUsers: migrated (0.0080s) =============================
rake aborted!

Tasks: TOP => db:migrate
(See full trace by running task with --trace)
Intenté volver a una confirmación anterior y ejecutar todo nuevamente, pero recibo el mismo mensaje de error. ¿Hay más archivos que debería agregar que puedan ayudar con esto?
He resuelto esto con
rake db:reset
Después de esto
rake db:migrate
trabajó.
Me encontré con esto también. Esto se debe a que ActiveRecord 4.2.0.beta4 pasa un parámetro a Arel::Nodes::BindParam.new
. Arel 6.0.0 acaba de ser lanzado hoy . En esta versión, BindParam
no acepta ningún parámetro en su inicializador.
ActiveRecord ya ha arreglado esto en la rama master
. Hasta que libere beta5, deberá bloquear su Gemfile
en gem ''arel'', ''6.0.0.beta2''
.
con la solución anterior de cambiar gemfile.
gem ''arel'', ''6.0.0.beta2''
Recibí el siguiente mensaje de error.
You have requested:arel = 6.0.0.beta2
The bundle currently has arel locked at 6.0.0.
Try running `bundle update arel`
Después
bundle update arel
funcionó
