Hello guys!!
I am facing a strange behavior, i dont know if is a bug or miss configuration, i have try a lot of things. 

```ruby
class User < ApplicationRecord
  has_one :consumer, dependent: :destroy
  has_one :power_plant, through: :consumer
end


class Consumer < ApplicationRecord
  belongs_to :user
  belongs_to :power_plant, optional: true
end


class PowerPlant < ApplicationRecord
  has_many :consumers, dependent: :nullify
end
```

When i try to detach a power_plant from user in avo destroy the model consumer too, like:
`User.first.power_plant=nil` destroy consumer.
`User.first.power_plant.destroy!` works, destroy only de power_plant.

can you create a reproduction app which I can try on my machine?

also, with some instructions on what you're doing in Avo?

I was looking deep, i think is not a AVO bug

Its a rails bug, i will publish in rails github

if you figure it out, please post the solution here too 😅
