Fecha de formato de los carriles

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

Utilizar

 Model.created_at.strftime("%FT%T") 

dónde,

 %F - The ISO 8601 date format (%Y-%m-%d) %T - 24-hour time (%H:%M:%S) 

A continuación, se incluyen algunas de las listas útiles de formatos de Date y Time que se pueden usar con frecuencia, que puede especificar en el método strftime :

 Date (Year, Month, Day): %Y - Year with century (can be negative, 4 digits at least) -0001, 0000, 1995, 2009, 14292, etc. %C - year / 100 (round down. 20 in 2009) %y - year % 100 (00..99) %m - Month of the year, zero-padded (01..12) %_m blank-padded ( 1..12) %-m no-padded (1..12) %B - The full month name (``January'') %^B uppercased (``JANUARY'') %b - The abbreviated month name (``Jan'') %^b uppercased (``JAN'') %h - Equivalent to %b %d - Day of the month, zero-padded (01..31) %-d no-padded (1..31) %e - Day of the month, blank-padded ( 1..31) %j - Day of the year (001..366) Time (Hour, Minute, Second, Subsecond): %H - Hour of the day, 24-hour clock, zero-padded (00..23) %k - Hour of the day, 24-hour clock, blank-padded ( 0..23) %I - Hour of the day, 12-hour clock, zero-padded (01..12) %l - Hour of the day, 12-hour clock, blank-padded ( 1..12) %P - Meridian indicator, lowercase (``am'' or ``pm'') %p - Meridian indicator, uppercase (``AM'' or ``PM'') %M - Minute of the hour (00..59) %S - Second of the minute (00..59) %L - Millisecond of the second (000..999) %N - Fractional seconds digits, default is 9 digits (nanosecond) %3N millisecond (3 digits) %6N microsecond (6 digits) %9N nanosecond (9 digits) %12N picosecond (12 digits)

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 ).

De APIdock:

Crea un inicializador para ello:

 # config/initializers/time_formats.rb 

Agregue algo así a esto:

 Time::DATE_FORMATS[:custom_datetime] = "%d.%m.%Y" 

Y luego úselo de la siguiente manera:

 post.updated_at.to_s(:custom_datetime) 

Your️ Tienes que reiniciar el servidor de Rails para que esto funcione.

Consulte la documentación para obtener más información: http://api.rubyonrails.org/v5.1/classes/DateTime.html#method-i-to_formatted_s

Como I18n es la característica principal de Rails a partir de la versión 2.2 , puede usar su método de localización . 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)
