ruby on rails 3 - Contextual validations in ActiveRecord using with_options and an array -

-

moving datamapper activerecord , 1 cool feature using contextual validations , using with_options pass array below:

with_options when: [:started, :completed] |v|   v.validates_with_method :has_data, method: :check_data_started? end

which fire validations within block if .valid?(:started) or .valid?(:completed) called.

is there way active record, tried:

with_options on: [:started, :completed] |v|   v.validate :check_data_started? end

which looks blows error saying can't pass array within with_options call, it's expecting 1 context:

/home/vagrant/.rbenv/versions/1.9.3-p327/lib/ruby/gems/1.9.1/gems/activesupport-3.2.12/lib/active_support/callbacks.rb:414: syntax error, unexpected '[', expecting tstring_content or tstring_dbeg or tstring_dvar or tstring_end ...ue && (validation_context == :[:started, :complet...

has done before?

figured out. if else runs problem, please see below solution:

with_options if: -> {[:started, :completed].include?(validation_context)} |v|   v.validates_with_method :has_data, method: :check_data_started? end

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
