I'm having trouble with three models that need to play nice together: - entry <- stores diary entries - entry_category <- links a diary entry to a category (entry_id, category_id) - category <- list of category names and attributes
I want to be able to :include => :categories when I perform a find, but I'm not sure if I have the model associations wrong or if my find syntax is wrong or both? An entry should only be able to be a part of one category. Here are the models: class EntryCategory < ActiveRecord::Base belongs_to :entry belongs_to :category end class Category < ActiveRecord::Base has_many :entry_categories has_many :entries, :through => :entry_categories end class Entry < ActiveRecord::Base belongs_to :user has_one :entry_category has_one :category, :through => :entry_category end I want to sum the price of all entries and include the category name. I can get all the entries grouped properly like so.... @entries = Entry.sum(:price, :conditions => ['user_id = 1'], :include => :entry_category, :group => 'entry_categories.category_id') ...how do I also get the category.name? If I try and include categories, the query doesn't work which makes me think i have a problem with my model associations. Any help would be greatly appreciated.
