Could you post your model's definition?, it looks like the association is incorrect

[Kukunin]

Got the same error on Rails 4.2.10. The problem is that my model reflections have string keys:

RSS::Post.reflections
=> {"post"=>
  #<ActiveRecord::Reflection::BelongsToReflection:0x007f90eeab6cc0
   @active_record=RSS::Post (call 'RSS::Post.connection' to establish a connection),
   @association_scope_cache={},
   @automatic_inverse_of=nil,
   @constructable=true,
   @foreign_type="post_type",
   @klass=nil,
   @name=:post,
   @options={:class_name=>"::Post"},
   @plural_name="posts",
   @scope=nil,
   @scope_lock=#<Thread::Mutex:0x007f90eeab6270>,
   @type=nil>,
 "rss_feed"=>
  #<ActiveRecord::Reflection::BelongsToReflection:0x007f90ef356880
   @active_record=RSS::Post (call 'RSS::Post.connection' to establish a connection),
   @association_scope_cache={},
   @automatic_inverse_of=nil,
   @constructable=true,
   @foreign_type="rss_feed_type",
   @klass=nil,
   @name=:rss_feed,
   @options={:class_name=>"RSS::Feed", :inverse_of=>:rss_posts},
   @plural_name="rss_feeds",
   @scope=nil,
   @scope_lock=#<Thread::Mutex:0x007f90ef355908>,
   @type=nil>,

so

    persistize :publisher_id, depending_on: 'rss_feed'

works. But there is another error then:

NoMethodError: undefined method `primary_key_name' for #<ActiveRecord::Reflection::BelongsToReflection:0x007f90fc5bfb78>
Did you mean?  primary_key_value
