handling stubbing errors

I wanted to stub a method call to raise an error for a test case, but I ran into an error:

allow_any_instance_of(MyClass).to receive(:foo).and_return("bar")

I got this error message:

Using any_instance to stub a method (foo) that has been defined on a prepended module (#<Module:0x0123>) is not supported.

A super easy fix for that was to create a double instance of my class:

let(:my_class_instance) { double(MyClass, foo: "bar") }

and then:

before do

allow(MyClass).to receive(:new).and_return(my_class_instance)

end

Adding foreign key using strong migrations gem

if the table is small, just wrap everything in a safety_assured block and you can add the foreign key and reference in one single migration.

Just don't forget to run a backfill task to normalize your data!
