Rails Eager Loading on All Finds

Question

OK, I've been playing around with some of the eager loading things, and have 2 models something like: ``` Class Recipe < ActiveRecord::Base belongs_to :cookbook has_many :recipetags end ``` and ``` Class Cookbook < ActiveRecord::Base has_many :recipes, :include => [:recipetags] end ``` Which is working out well, when I find a Cookbook, then I eager load the recipes, and in turn the recipes eager load the :recipetags: ``` cb = Cookbook.find(10590, :include => [:recipes]) ``` But what I want to also do is whenever I open a recipe, have it pull in all of it's eager associations automatically - basically I want to do: ``` rec = Recipe.find(123) ``` and have it eager load the :recipetags in that case as well. I realize this seems trivial, but in actuality I have about 4-5 associations on Recipe, I'm just not showing them here, and rather than having to explicitly do the :include on every find call I'd like it to just happen. I'm assuming I can override Recipe.find to do it in the Recipe mo…

Accepted Answer

I've been using default_scope to do it on selected models where I always want to eager load:

```
class Post < ActiveRecord::Base
  has_many :comments
  default_scope :include => :comments, :order => ["title ASC"]
  ...
end
```
