继续获取ActiveRecord :: AssociationTypeMismatch(Keep getting ActiveRecord::AssociationTypeMismatch)

 我一直在努力解决这个问题好几天。 我一直收到错误： 
 
ActiveRecord::AssociationTypeMismatch in SatellitesController#create

Satellite(#70098878574220) expected, got String(#70098849353340)
 
 我看过这个网站，但似乎没有任何帮助。 这是我到目前为止在我的代码中所拥有的： 
 
 在我的new.html.erb文件中： 
 
<%= form_for( @satellite ) do |f| %>
<div class="field">
    <%= f.label :parent_id %></br>
    <%= f.select( :parent_id, Satellite.all.collect { |s| [ s.name, s.id ] }, { :include_blank => '-select-' } ) %>
</div>
 
 这就是我正在使用的关联： 
 
class Satellite < ActiveRecord::Base

  validates :name, :presence => true, :uniqueness => true

  has_many :satellites, class_name: 'Satellite', foreign_key: 'parent_id'
  belongs_to :parent_id, class_name: 'Satellite', foreign_key: 'parent_id'
end
 
 任何帮助将不胜感激！ 

I have been working on fixing this problem for days. I keep getting the error:
 
ActiveRecord::AssociationTypeMismatch in SatellitesController#create

Satellite(#70098878574220) expected, got String(#70098849353340)
 
I have looked all over this site but nothing seems to help. This is what I have in my code so far:
 
In my new.html.erb file:
 
<%= form_for( @satellite ) do |f| %>
<div class="field">
    <%= f.label :parent_id %></br>
    <%= f.select( :parent_id, Satellite.all.collect { |s| [ s.name, s.id ] }, { :include_blank => '-select-' } ) %>
</div>
 
And this is the association I am using:
 
class Satellite < ActiveRecord::Base

  validates :name, :presence => true, :uniqueness => true

  has_many :satellites, class_name: 'Satellite', foreign_key: 'parent_id'
  belongs_to :parent_id, class_name: 'Satellite', foreign_key: 'parent_id'
end
 
Any help would be GREATLY appreciated!
