NYC Standup 04/24/2012: Loading OBJECTS through associations..

Cathy O'Connell

Tuesday, April 24, 2012

Interesting Things

When you load objects through associations, you should be aware of how the objects are being loaded. If a where statement is used the calls are being translated to SQL and always hitting the database.

example

it "should whatever" do
      foo.bars.where(something: true).each { |bar|        bar.modify_something }
      foo.bars.each { |bar| bar.expect_something_to_be_modified }
end

This will fail as the first call is not only limiting the association but also loading different objects to the second foo.bars collection.
Choosing first on a has_many association is dangerous. There are two ‘first’ functions a class and an array one. Depending on whether the association is loaded, a different method is called.

example

it "should do something with the first element" do
    foo.bars.first.modify_something
    foo.bars(:force_load).first
end

To ensure loading occurs and thus the object is the same on every call, you can provide any value that evaluates to true as part of the association call. Here :force_load symbol, evaluates to true and forces a database load for bars.

No answer yet. It was tested by confirming a method that the base method referenced was called. Solution welcome.

Ask for Help

Rails Validates uniqueness allows nils. The database (psql and mysql) allows unlimited nils.
*BUG – The app did not allow unlimited nulls.
*Cause – The development structure had an allow nil false but the model file had allow nil true. This caused odd behaviour.
