Question:
I'm working with cocoon gemfile & following the ERB style of it without haml/slim. I have my github here - The branch I'm working on is "cmodel" - Link.
The error is: Unpermitted parameter: ingredient_attributes
Really what I don't understand is just about everything about the models. I get pluralization is a thing. I get that strong parameters is a thing. My understanding to implement them is a bit fuzzy. I've found the rails guides & edge rails guides too simple for the expanded use here. I've flailed around with 80+ changes and feel like I've borked my install completely.
Some extras that I did:
- adding excessive accepts_attributes_for to blindly in models trying to guess issue
I added a non-pluralized strong parameter to try and find out if this is the issue
added ingredients to the quantities_attributes - blindly hoping this was it
Removed all ingredient(s)_attribute(s)
I have a weird schema now, put stuff into db probably shouldn't have
Pulled the ingredients & quantities from permitted strong parameter list. Then added in quantities_attributes - with no issues. Then tried the same with ingredient(s)_attributes ... the issue still exists.
updated @ 08:29pm - 12/25/15:
Weird side effect ... 15 or 20 tests ago I noticed the 2nd field when you click the add ingredient link worked to add, but the 2nd column does not display when you click edit. Possibly related?
I guess in summary this should all work - it matches another example used by someone else & there's no reason it should fail according to an example.
The code is completely non-responsive to the pluralization in the strong parameters area - it's frustrating. I think my developing method is pretty borked at this point, going to take a break after 4 hours of this junk.

Setup
- I ran the bundle install for the gemfile.
- I made the entry in assests/application.js for the "//= require cocoon". It's been compiled and raked.
- I setup a controller to view ingredient model directly and can add them manually through the ingredient page - but it never saves my ingredient via the Recipe model.
Models:
class Recipe < ActiveRecord::Base
has_many :quantities
has_many :ingredient,
:through => :quantities
accepts_nested_attributes_for :quantities,
:allow_destroy => true
accepts_nested_attributes_for :ingredient
end
class Quantity < ActiveRecord::Base
belongs_to :recipe
belongs_to :ingredient
accepts_nested_attributes_for :ingredient
end
class Ingredient < ActiveRecord::Base
has_many :quantities
has_many :recipes, through: :quantities
accepts_nested_attributes_for :quantities
end

回答1:
Your recipe_params method needs to be changed - you actually have two levels of nesting in your form (Recipe -> Quantity -> Ingredient) so your parameter permitting needs to reflect this.
In your method, remove the ingredient_attributes and ingredients_attributes part - they don't match the format of your submitted params. Instead, you want something like the following:
:quantities_attributes => [:id, :ingredient, :ingredient_id, :recipe_id, :amount,
:_destroy, :ingredient_attributes => [:id, :_destroy, :ingredient_id, :name]]
