How do you go about spec’ing model associations?
There’s an idea on the rspec mailing list.
However, I kind of like using reflect_on_association. Let’s say we have the following model:
class Product < ActiveRecord::Base has_and_belongs_to_many :categories has_many :images has_many :inventories belongs_to :designer end
Then my context and specifications might look like:
context "Product model" do
specify "should respond to inventories" do
Product.reflect_on_association(:inventories).should_not_be_nil
end
specify "should respond to categories" do
Product.reflect_on_association(:categories).should_not_be_nil
end
specify "should respond to images" do
Product.reflect_on_association(:images).should_not_be_nil
end
specify "should respond to designer" do
Product.reflect_on_association(:designer).should_not_be_nil
end
end
This will catch the situation where an association definition is removed or changed.
