Fecha de formato de los carriles (4)
Estoy publicando una fecha en una API y el formato requerido es el siguiente:
2014-12-01T01:29:18
Puedo obtener la fecha del modelo así:
Model.created_at.to_s
Eso vuelve:
2014-12-01 01:29:18 -0500
¿Cómo puedo usar Rails o Ruby para formatearlo como el formato requerido con la T y eliminar el -0500?
Gracias
Como I18n es la característica principal de Rails a partir de la versión 2.2 , puede usar su método de localize . Al aplicar las % -variables de% de tiempo antes mencionadas , puede especificar el formato deseado en config/locales/en.yml (o cualquier idioma), en su caso de esta manera:
time:
formats:
default: ''%FT%T''
O si desea utilizar este tipo de formato en algunos lugares específicos, puede referirlo como una variable como esta
time:
formats:
specific_format: ''%FT%T''
Después de eso, puedes usarlo en tus vistas de esta manera:
l(Mode.last.created_at, format: :specific_format)
En
environment.rb
puedes agregar algo como esto:
Time::DATE_FORMATS[:custom_datetime] = "%d.%m.%Y"
y luego úselo de la siguiente manera:
post.updated_at.to_s(:custom_datetime)
`
Prueba esto:
created_at.strftime(''%FT%T'')
Es una función de formato de tiempo que le proporciona una forma de presentar la representación de cadena de la fecha. ( http://ruby-doc.org/core-2.2.1/Time.html#method-i-strftime ).
