Hello,
In User model: has_many :projects, :through => :authorizations
In view: render :partial => @user.projects
This blows up because HasManyThroughAssociation inherits from AssociationProxy and not AssociationCollection.
Partial logic checks if @user.projects === AssociationCollection which returns false.
Quick workaround is: render :partial => @user.projects.to_a
(actionpack/lib/action_view/partials.rb rev8129 line 122):
def render_partial(partial_path, object_assigns = nil, local_assigns = nil) #:nodoc: case partial_path ... when Array, ActiveRecord::Associations::AssociationCollection ...
Should it be changed to "when Array, ActiveRecord::Associations::AssociationProxy" or HasManyThroughAssociation should inherit from AssociationCollection?
