Rails Console: reload! not reflecting changes in model files? What could be possible reason?

Earlier it was working fine. I have been playing little bit config. So may be i have changed some config unknowingly.

here is config of environment/development.rb

  config.cache_classes = false

  # Log error messages when you accidentally call methods on nil.
  config.whiny_nils = true

  # Show full error reports and disable caching
  config.consider_all_requests_local       = true
  config.action_view.debug_rjs             = true
  config.action_controller.perform_caching = false

  # Don't care if the mailer can't send
  config.action_mailer.raise_delivery_errors = false

  # Print deprecation notices to the Rails logger
  config.active_support.deprecation = :log

  # Only use best-standards-support built into browsers
  config.action_dispatch.best_standards_support = :builtin

  # migration prefix with sequence #s
  config.active_record.timestamped_migrations = false

  #time zone
  config.time_zone = 'UTC'

Here is config section of application.rb

 # Configure the default encoding used in templates for Ruby 1.9.
 config.encoding = "utf-8"

 # Configure sensitive parameters which will be filtered from the log file.
 config.filter_parameters += [:password]

 config.active_record.schema_format = :sql

when i run reload! on rails console it return true

reload! only reloads the latest code in the console environment. It does not re-initialize existing objects.

This means if you have already instantiated any objects, their attributes would not be updated - including newly introduced validations. However, if you create a new object, its attributes (and also validations) will reflect the reloaded code. more here

Are you reloading the object from the database?

For example:

>> a = User.last
=> #<User id: 16, email: "[email protected]">
>> reload!
Reloading...
=> true

'a' won't reflect any changes to your model until you reload it from the db.
