Fixtures and associations

Testing RSpec
1

Hello… I want ask for a help in error that don’t understand.

I have properties model and tenants model. Tenant belongs to Property
and
Property has many Tenants… I try this test association but allways get
“not valid” error for association. Anyone can help? I post all my
classes
below:

My Tenant class:
class Tenant < ActiveRecord::Base
belongs_to :property

validates_associated :property
validates_presence_of :property
…

My tenant_spec.rb
describe Tenant do
fixtures :properties

def create_tenant(options = {})
record = Tenant.create({
:property => properties(:two),
:renters => “value for renters”,
:guarantor => “value for guarantor”,
:contact_name => “value for contact_name”,
:contact_phone => “value for contact_phone”,
:contact_email => “[email protected]”,
:end_date => Date.today,
:beginning_date => Date.today,
:initial_value => “9.99”
}.merge(options))
end

before(:each) do
@tenant = create_tenant
end

it “should create a new instance given valid attributes” do
@tenant.errors.should be_blank
end
…

My property_spec.rb
class Property < ActiveRecord::Base
has_many :tenants
…

My properties.yml:
two:
user: aaron
owner: tania
address: Rua de teste
address_number: 250
neighborhood: Bairro ABC
country_state: MG
country: Brasil
city: Belo Horizonte

Hi Daniel,

Are both tenant_spec and property_spec failing? What are the failure
messages you’re getting?

Hello David, the error is only in tenant_spec … in property_spec all
my
examples passed. The error is in “@tenant.errors.should be_empty” line
and
the message is expected empty? to return true, got false
If I use puts to print my @tenant object before the assertion I get
those
values:

#<ActiveRecord::Errors:0x23aabf4
@errors={“property”=>[“is not valid”]},
@base=#<Tenant id: nil,
property_id: 996332877,
renters: “value for renters”,
guarantor: “value for guarantor”,
contact_name: “value for contact_name”,
contact_phone: “value for contact_phone”,
end_date: “2008-12-17”,
beginning_date: “2008-12-17”,
initial_value: #BigDecimal:239a4fc,‘0.999E1’,8(8),
created_at: nil,
updated_at: nil,

Hi Daniel,

What happens when you do

properties(:two).valid?
p properties(:two).errors

It looks like that fixture is not valid.

You are loading the users fixtures. You need to change your fixtures
line to read

fixtures :properties, :users

(and any other models’ fixtures you want to use)

I highly recommend ditching fixtures all together. You avoid funky shit
like this, and you won’t have coupling between tests that occurs with
fixtures, and you’ll be able to create more clear specs because you do
all the setup in the spec itself. If you’re interested, look into
something like fixtures_replacement, factory girl, object daddy, etc.
Personally, I use a little 15-line homebrew framework.

I get cannot be null error user in active record object… like below:
properties(:two).valid? return false, but I don’t understand why…
because
my properties.yml file is like below:

two:
user: aaron
owner: tania
address: Rua de teste
address_number: 250
neighborhood: Bairro ABC
…

and my users.yml is:

aaron:
id: 2
login: aaron
name: aaron lorem
email: [email protected]
…

But my activerecord object return this:

#<ActiveRecord::Errors:0x239be10 @errors={“user”=>[“can’t be blank”]},
@base=#<Property id: 996332877,
user_id: 317248456,
owner_id: 465176508,
address: “Rua de teste”,
address_number: “250”,
neighborhood: “Bairro ABC”,
country: “Brasil”,
city: “Belo Horizonte”,
area: “150m”,
constructed_area: “120m”,
category: “galpão”,
usage: “comercial”,
owner_code: “AS341ADV”,
condominium_value: #BigDecimal:2389274,‘0.0’,4(8),
iptu_value: #BigDecimal:2389238,‘0.905E2’,8(8),
garage: 2,
description: “Casa com 3 quartos”,
observation: nil,
cep: “30566500”,
country_state: “MG”,
created_at: “2008-12-17 20:11:11”,
updated_at: “2008-12-17 20:11:11”,
zoning: “z10” >>

But it is not blank. What i’m doing wrong on my fixtures files? I think
I
don’t get the message yet in other model spec because this is the fist
model
that use properties.yml ( in properties_spec I only use fixtures for
users )

Hello Pat, even I load all my fixtures it still not reading anything
from
users.yml …
I will look at factory_girl but before I need understand what happening.

I try this:

require File.expand_path(File.dirname(FILE) + ‘/…/spec_helper’)

describe Tenant do
fixtures :properties, :users , :owners

def create_tenant(options = {})
record = Tenant.create({
:property => properties(:two),
:renters => “value for renters”,
:guarantor => “value for guarantor”,
:contact_name => “value for contact_name”,
:contact_phone => “value for contact_phone”,
:contact_email => “[email protected]”,
:end_date => Date.today,
:beginning_date => Date.today,
:initial_value => “9.99”
}.merge(options))
end

before(:each) do
@tenant = create_tenant
end

it “should create a new instance given valid attributes” do
p properties(:two).errors
properties(:two).should be_valid
# @tenant.errors.should be_empty
end

end

Hello Pat, the error still the same.@errors={“user”=>[“can’t be blank”]}

But if we look on @base we have user:
@base=#<Property id: 996332877, user_id: 317248456, owner_id: 465176508,
…

And my code is:
describe Tenant do
fixtures :properties, :users ,:owners

def create_tenant(options = {})
record = Tenant.create({
:property => properties(:two),
:renters => “value for renters”,
:guarantor => “value for guarantor”,
:contact_name => “value for contact_name”,
:contact_phone => “value for contact_phone”,
:contact_email => “[email protected]”,
:end_date => Date.today,
:beginning_date => Date.today,
:initial_value => “9.99”
}.merge(options))
end

before(:each) do
@tenant = create_tenant
end

it “should create a new instance given valid attributes” do
properties(:two).valid?
p properties(:two).errors
# @tenant.errors.should be_empty
end

And my fixtures still the same… I don’t know what’s happening, when I
try
run on console or in browser everything ok… I think is something
strange
with fixtures.

Just a small tip. Always, always use create! in specs. You want an error
to
be raised in case creation is unsuccessful, and create doesn’t do that -
it
just returns false.

I know… I just don’t use create!, in this special case, because it
will be
more complicate to know what field have the error .
I’m still scratching my head, my @tenant instance var on spec has values
for
user_id and owner_id and don’t understand why my validates_associated
:property raise an error.

And if I mock model on model spec will not be a good thing.

No it won’t. The error message tells you what field has the error, and
if
creation is unsuccessful you need to know about it. Otherwise you’ll
get
tons of false positives. I can’t think of a single case where it makes
sense
to use create inside a spec.

Aslak

I think I was misunderstood. I am not saying to use create rather than
create! … In this case, I just use it because will help me with puts
for
debug my own error in spec.
In this case a really don’t know what is going on, if I use create! I
can’t
store the value in a var and then try to look what is the message of the
failed attribute with puts.
I using puts to print the error object to debug who is the wrong
attribute.
If I use create! I will have this message:
Validation failed: Property is not valid => and cant use puts to know
the
content of @errors

If I use create and print the result of fixture I will get:

<ActiveRecord::Errors:0x23af4b0 @errors={“user”=>[“não pode ser
vazio”]},
@base=#<Property id: 996332877, user_id: 317248456, …

And find the problem, it is just for debugging and help me to find where
is
the problem, after fix this I will change to create! again.

–

Anyone can figure why even property_id and owner_id are defined still
raise
“can’t be blank” ?

Thanks a lot for all help.

What error are you getting now? Please post whatever error you’re
experiencing…when we change this code, I expect a different error,
and would not know what it is. If it’s the same, that’s strange.

Also, I noticed you have
p properties(:two).errors
properties(:two).should be_valid

That’s not going to show you anything, because errors don’t get added
until you call #valid? So change that to

properties(:two).valid?
p properties(:two).errors

I really don’t know what’s going on with those hell fixtures, and start
thinking I will never find… I will try migrate all my fixtures to
factory-girl, the only problem are my six hundred examples and no time
to
change all. Somebody have any link about rspec + factory-girl ? or maybe
link to any project on github that use factory-girl and rspec ?
Thanks for all help.

You don’t have to change all your fixtures to factories right now, of
course, and, indeed, you should not. Just change the ones that are
giving
you problems for now; and later, maybe, change each on as you work on
it.

So, I think the problem is my fixture became crazy with id’s and not
assign
the right id for the right object in association when I try use Rails 2
sintax for fixtures ( omitting the ids and using the name of the fixture
in
the association instead of id ) … when I change everything to fixed id
in
my yml files everything works.
Crazy. I’m still want to migrate to factory-girl, if anybody has
material or
links on github about projects using rspec and factory-girl will help
alot.
