I have the current models setup in my Rails app:
Recipe has_many :items, :through => :item_linkers has_many :item_linkers, inverse_of: :recipe ItemLinker belongs_to: recipe, inverse_of: :item_linkers belongs_to: item, inverse_of: :item_linkers Item has_many :recipes, through: :item_linkers has_many :item_linkers, inverse_of: :item
In my show page I currently display all recipes that use a particular ingredient like this:
<% @item.item_linkers.each do |item_linker| %> <% item_linker.recipe.name %> <% end %>
This is not the most elegant way imo and would like to do something like this in the controller:
@recipes = @item.recipes
Followed by this in the show page:
<% @recipes.each do |recipe| %> <% recipe.name %> <% end %>
But that doesn't seem to work. I get the following error. Any solutions on achieving this?
Cannot have a has_many :through association 'Item#recipes' which goes through 'Item#item_linkers' before the through association is defined.
