Rails 4 未采用参数列表 - 控制台出错 - actionView::Template::error
Rails 4 not taking parameter list - error in console - actionView::Template::error
更新：我在这里有两个问题 - 控制台中列出的那个与我发布的标题不匹配。 actionView::Template::error 的问题实际上是由于缺乏复数引起的 - 我在下面给出了最完整的答案 - 谢谢！
原题：
我正在使用 cocoon gemfile 并在没有 haml/slim 的情况下遵循它的 ERB 风格。我这里有我的 github - 我正在处理的 b运行ch 是 "cmodel" -Link。我自己解决了一个错误 - 但最后一个错误是难以捉摸的 - 也很奇怪 - 我丢失了通常显示成分和数量的字段 - 回到重点...
我的问题是...因为当我在 github 上搜索我的回购时 "ingredient_attributes" 并且仅在我的控制器参数中看到它...错误来自哪里以及如何修复它？
"Unpermitted parameter: ingredient_attributes"
或
"Unpermitted parameter: ingredients" 来自...我设法使它大部分工作 - 这是最后一个元素，我已经处理了大量文件并声明复数等，并尝试了 3 或 4 accept_parameters_for 的格式，然后是 ingredient_attributes.
的格式
当前错误的控制台输出：

设置
- 我运行 gemfile 的捆绑包安装。
- 我在 assests/application.js 中输入了“//= require cocoon”。它已经过编译和整理。
- 我设置了一个控制器来直接查看配料模型，并可以通过配料页面手动添加它们 - 但它从不通过配方模型保存我的配料。
型号：
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
控制器：
class RecipesController < ApplicationController
before_action :set_recipe, only: [:show, :edit, :update, :destroy]
# GET /recipes/1/edit
def edit
@recipe = Recipe.find(params[:id])
end
# POST /recipes
# POST /recipes.json
def create
@recipe = Recipe.new(recipe_params)
respond_to do |format|

声明关联 class 配方 与 has_many 关系时出错。
尝试在 配方模型
中更改与以下内容的关系
has_many :ingredients
作为 Praveen George 答案的补充，如果您按照屏幕上的说明（大部分时间）进行操作，则可以相对简单地调试 Rails：
No association found for name `ingredients'. Has it been defined yet?
这基本上意味着您没有在您调用的模型中定义 ingredients 关联。
正如Praveen所指出的，您的问题出在Recipe模型上。您必须以复数名称来称呼该协会：
#app/models/recipe.rb
class Recipe < ActiveRecord::Base
has_many :ingredients
accepts_nested_attributes_for :ingredients
end
