How to stub a has_many relationship in Rails 2.3.5

We have a test that has been working find until we upgraded to rails
2.3.5.
I’m not too familiar with mocks/stubs so maybe there is an easy
solution.

Here is a simple example of our scenario.

Class Person < ActiveRecord::Base

has_many :aliases, :dependent => :nullify

before_destroy :mark_aliases_as_deleted

def mark_aliases_as_deleted

self.aliases.each do |alias|

  alias.mark_as_deleted

end

end

end

This is a test to ensure that when the Person is destroyed that all of
their
Aliases get their mark_as_deleted method called. I know this example
isn’t
very practical, but it is the simplest way I could think of to describe
our
problem.

it “should trigger mark_as_deleted in related aliases” do

aliases = []

3.times do |i|

alias = mock("alias #{i}")

alias.should_receive(:mark_as_deleted)



aliases << alias

end

@person.stub!(:aliases).and_return(aliases)

@person.destroy

end

So the problem we are encountering in our scenario is that we get a
NoMethodError exception (undefined method `owner_quoted_id’ for
#Array:0x9a0608c) when trying to destroy the Person because the
stubbed
Aliases return an array and it appears it is expecting some sort of
association object that responds to owner_quoted_id

Like I said, we didn’t have any problems until upgrading from Rails
2.3.4 to
Rails 2.3.5

In case your interested, it is the configure_dependency_for_has_many
method
that calls: “#{reflection.primary_key_name} =
#{record.#{reflection.name}.send(:owner_quoted_id)}”

Any help would be greatly appreciated!

There are two ways I would try to go on this. One would be to add the
aliases to the actual association:

it “should trigger mark_as_deleted in related aliases” do
3.times do |i|
alias = mock(“alias #{i}”)
alias.should_receive(:mark_as_deleted)
@person.aliases << alias
end

@person.destroy
end

The other would be to stub owner_quoted_id on the array:

it “should trigger mark_as_deleted in related aliases” do
aliases = []
aliases.stub(:owner_quoted_id)

3.times do |i|
alias = mock(“alias #{i}”)
alias.should_receive(:mark_as_deleted)
aliases << alias
end

@person.stub!(:aliases).and_return(aliases)

@person.destroy
end

I’m not sure that either would work :slight_smile: But that’s where I’d start.
