_destroy doesn't work

It might be good to mention in the readme the need for :allow_destroy => true in the accepts_nested_attributes_for call.

That's strange, I'm not sure what the issue could be. Do you have attr_accessible in the image model? You can try adding _destroy there but you shouldn't have to.

You can check out the nested_form branch of the complex-form-example project for a working example.

How can I debug "the model" to find the problem? I use the following in the parent model:

attr_accessible ..., :avatars_attributes

has_many :avatars, :as => :avatarable, :dependent => :destroy   
accepts_nested_attributes_for :avatars, :allow_destroy => true

[SOLVED] Problem solved. I have moved the code above to the superclass. If the code is in the subclass model than the destroy doesn't work!

[ryanb]

Glad you got it solved, that's a strange bug but thank you for reporting.

[ryanb]

Good point. I'll reopen this for that readme addition.

i had the same problem in rails 3.1.0.rc8 - but to add :allow_destroy => true does the trick - also today in rails 3.1 …
thanks for this gem :)
