我有食谱、成分Ingredient_Recipe模型
食谱有
has_many :ingredient_recipes
has_many :Ingredients, :through => :RecipeIngredient
成分有
has_many :ingredient_recipes
has_many :Recipes, :through => :RecipeIngredient
Ingredient_Recipe有
belongs_to :recipes
belongs_to :ingredients
在我的 UI 中,这不再有效
<% @recipe.ingredients.each do |ingredient| %>
编辑
ActionView::Template::Error (uninitialized constant Recipe::Ingredients):
97: </td>
98: <tr>
99: <td >
100: <% @recipe.ingredients.each do |ingredient| %>
101: ingredient.name
102: <% end %>
103: </td >
更改:
has_many :Ingredients, :through => :RecipeIngredient
自
has_many :ingredients, :through => :ingredient_recipes
不要大写 :ingredients,并且 :through 需要引用您正在经历的关联而不是模型。
对于 :食谱:
has_many :recipes, :through => :ingredient_recipes
