Assert_equal Test - how to test updates

Rails
1

I am testing an update via assert_equal and it does not seem to work.

I have this fixture:
bob1:
id: 1000001
login: bob
glogin: [email protected]
session_token: 77a38

Here is my test method:
class Guser < ActiveRecord::Base
def self.update_token(glogin, login, stoken)
u=find(:first, :conditions=>[“glogin = ? AND login = ?”, glogin,
login])
return nil if u.nil?
if u.session_token != stoken
u.session_token = stoken
u.save
return u
end
#nil
end
end

Here is where I call the method, where I match the ‘glogin’ and ‘login’
column values and if they match I want to update the session token.

require File.dirname(FILE) + ‘/…/test_helper’
class GuserTest < ActiveSupport::TestCase
self.use_instantiated_fixtures = true
fixtures :users
def test_match_login
assert_equal @bob1, Guser.update_token(“[email protected]”, “bob”,
“77a38”)
end

The first time even if there is no record in the database it inserts and
gives a success message:
1 tests, 1 assertions, 0 failures, 0 errors, 0 skips

Then I run it again by changing the method argument like this to update
the
sesison token
assert_equal @bob1, Guser.update_token(“[email protected]”, “bob”,
“77a138”)
It still gives a success message: 1 tests, 1 assertions, 0 failures, 0
errors, 0 skips

The new value of session token is never updated in the table column from
‘77a38’ to ‘77a38’ . Can you please tell me how to update the sesison
token
if my glogin and login fields are found to match

I meant it does not update the value from ‘77a38’ to ‘77a138’

assert_equal uses the == method to compare the two objects, and == on
activerecord doesn’t compare attributes: it only compares the id of
the object (ie do the compared objects represent the same row in the
database)

Thank you.
To perform an update I have to find if the existing attribute(database
column) value is equal to new value that I pass, and then overwrite it
if it
does not match. How can I test this situation - can you please tell me?

A small addition: it obviously also compares class and there’s some
fiddly stuff around handling the cases of unsaved objects

This tell me that we have make sure IDs are unique across fixtures from
different models. That is confusing each model has to have its own space.

if you are using instantiated fixtures, then yes, each fixture needs
its own label, but no one does that any more. If you want the bob
fixture from users write users(:bob) and for the other one gusers
(:bob)

That is why I had this issue. I had two fixtures users.yml and
gusers.yml.
Both had ‘bob’ defined with same record ID. Now users.yml was referred
by
user controller and gusers.yml was referred by gusers controller.
However
when I did assert_equal using gusers it pulled the record from the users
model instead of gusers model. I could not understand that behavior.
When I changed the gusers.yml ‘bob’ to ‘bob1’ it pulled the record from
the
correct gusers model.

This tell me that we have make sure IDs are unique across fixtures from
different models. That is confusing each model has to have its own
space.
