Re: [rspec-users] Rails - Mock going out of scope?

2007-07-18 Thread Mikel Lindsaar
Makes total sense.

Thank you _very_ much David :)  All works well and handles another
question I have on a disrelated matter.

By the way, loving RSpec.  Makes testing a lot more interesting and
rewarding.  Thanks for all your work.

Regards

Mikel

Re: [rspec-users] Rails - Mock going out of scope?

2007-07-18 Thread David Chelimsky
D'oh. I should have figured this out on first sighting:

The parent method does a find, so it retrieves a new object from the
db - not the instance of Node you have defined. This new instance has
no language associated with it (because the one you gave it pretends
to exist by sporting an ID, but is never saved to the DB).

Make sense?

So, if you want to mock this, you have to mock a bit more than what
you have in mind. Check out this pastie:

Re: [rspec-users] Rails - Mock going out of scope?

2007-07-18 Thread David Chelimsky
Here are the errors I'm getting now:

1)
NoMethodError in 'Node instance should return it's parent's language
if it is a child'
undefined method `move_to_child_of' for #
./spec/models/node_spec.rb:20:

2)
NameError in 'Node instance should return it's own language if it is root'
undefined local variable or method `parent' for #
/Users/david/projects/ruby/nodes/config/../app/models/node.rb:7:in
`language_name'
./spec/models/node_spec.rb:16:

What version of rails are you using? And is there a plugin you're
using for nested set?

Re: [rspec-users] Rails - Mock going out of scope?

2007-07-18 Thread Mikel Lindsaar
Here are the migrations:

class CreateNodes < ActiveRecord::Migration
  def self.up
create_table ("nodes", :options => 'ENGINE=InnoDB DEFAULT
CHARSET=utf8', :force => true) do |t|
  t.column "title",:string
  t.column "language_id",  :integer
  t.column "parent_id",:integer
  t.column "lft",  :integer
  t.column "rgt",  :integer
  t.column "original_node_id", :integer
  t.column "owner_id", :integer
  t.column "owner_type",   :string
  t.column "root_id",  :integer
end
  end

  def self.down
drop_table "nodes"
  end
end

class CreateLanguagesTable < ActiveRecord::Migration
  def self.up
create_table (:languages, :options => 'ENGINE=InnoDB DEFAULT
CHARSET=utf8', :force => true) do |t|
  t.column :name, :string
end
  end

  def self.down
drop_table :languages
  end
end


The Nodes Model also has a self referrential association, but I don't
think that would be causing any problems.

class Node < ActiveRecord::Base
  belongs_to :language
  belongs_to :owner, :polymorphic => true

  # Self referrential association, nodes have many original nodes - keeps track
  # of all original => translation associations
  belongs_to :original_node, :class_name => "Node", :foreign_key =>
"original_node_id"
  has_many :translated_nodes, :class_name => "Node", :foreign_key =>
"original_node_id"

  acts_as_nested_set :scope => :root_id

  #  + code from the original pastie

end


There are some other associations, but they are all belongs_to or
has_many, so I haven't bothered to put all the tables in here and have
removed the appropriate foreign keys from the nodes table.

Mikel

Re: [rspec-users] Rails - Mock going out of scope?

2007-07-18 Thread David Chelimsky
You might also want to try this w/ another mock framework like mocha
or flexmock (or rr if you're on edge). If you do, please report the
results here.

Thx

Re: [rspec-users] Rails - Mock going out of scope?

2007-07-18 Thread Mikel Lindsaar
Heya David,

Thanks for the reply.

No, that didn't work, get the same error:

NoMethodError in 'Node instance should return it's parent's language
if it is a child'
You have a nil object when you didn't expect it!
The error occurred while evaluating nil.name


If I include the fixture :languages, then replace out @language =
mock_model... with

@language = languages(:one)

it all works dandy.  But I'm trying to ween myself off fixtures :)

Regards

Mikel

It's generally not recommended that you set expectations, invoke them
and then set them again. I'm not sure, but that may be the problem
here. Try this:

  it "should return it's parent's language if it is a child" do #
Fails (message below)
@section1.move_to_child_of(@node)
@chapter1.move_to_child_of(@section1)
@language.should_receive(:name).exactly(:twice).and_return("Japanese")
@section1.language_name.should == "Japanese"
@chapter1.language_name.should == "Japanese"
  end

Does that work?

[rspec-users] Rails - Mock going out of scope?

2007-07-18 Thread Mikel Lindsaar
Hello list,

I think I have a rails related RSpec problem with a mock going out of
scope on a recursive call to a model.

The code is at: http://pastie.textmate.org/79821 if you want to see it
highlighted.  I have pasted it below as well.

Basically, I have an acts_as_nested_set model called "Node", which
works fine.  I have a function which finds the language name of the
node instance.  If the language is nil for the node instance being
queried, it then recursively calles language_name on it's parent until
one of them has the language.  Then this gets returned.

When I do this with a fixture, it works fine.  Ie, a Database call can
be made to a language table and I get the language name.

In the code attached it has a langauge instance being mocked.  I get
the same result if I mock Language.should_receive(:find)...

It SEEMS like the Mock is going out of scope on the recursive call to
parent.  The direct spec to the parent to get language name works
fine.

Any ideas? (the code below is slimmed down to the code needed to run the spec.

Regards

Mikel

CODE::

class Node < ActiveRecord::Base

  belongs_to :language
  acts_as_nested_set :scope => :root_id

  def language_name
self.root? ? language.name : parent.language_name
  end
end

describe Node, "instance" do

  fixtures :nodes

  before(:each) do
@language = mock_model(Language, :name => "Japanese")
@node = Node.create!(:language => @language)
@section1 = Node.create!()
@chapter1 = Node.create!()
  end

  it "should return it's own language if it is root" do  # Passes
@language.should_receive(:name).exactly(:once).and_return("Japanese")
@node.language_name.should == "Japanese"
  end

  it "should return it's parent's language if it is a child" do #
Fails (message below)
@section1.move_to_child_of(@node)
@chapter1.move_to_child_of(@section1)
@language.should_receive(:name).exactly(:once).and_return("Japanese")
@section1.language_name.should == "Japanese"
@language.should_receive(:name).exactly(:once).and_return("Japanese")
@chapter1.language_name.should == "Japanese"
  end
end

NoMethodError in 'Node instance should return it's parent's language
