A proxy for the association. Calling an array method will load the associated objects and call the method on the associated object array. Calling any other method will call that method on the association’s dataset.
Constants
| DEFAULT_PROXY_TO_DATASET | = | proc do |opts| array_method = array.respond_to?(opts[:method]) if !array_method && opts[:method] == :filter Sequel::Deprecation.deprecate "The behavior of the #filter method for association proxies will change in Ruby 2.6. Switch from using #filter to using #where to conserve current behavior." end !array_method end |
Default proc used to determine whether to send the method to the dataset. If the array would respond to it, sends it to the array instead of the dataset. |
Public Class methods
new(instance, reflection, proxy_argument, &proxy_block)
Set the association reflection to use, and whether the association should be reloaded if an array method is called.

Public Instance methods
method_missing(meth, *args, &block)
