I have the following STI table:
def self.up create_table :distributions do |t| t.string :type t.integer :simulation_id t.string :dist_name t.string :desc, :default=> 'fixed' t.float :param1, :default => 5.0 t.float :param2, :param3 t.timestamps
#fields for RscDist t.integer :resource_id
#fields for LoadDist t.integer :load_id end end
My model file looks like this:
class Distribution < ActiveRecord::Base
validates_presence_of :desc, :param1 validates_uniqueness_of :dist_name, :scope => "simulation_id" validates_inclusion_of :desc, :in => %w{fixed exponential normal uniform triangular}, :message => "should be 'fixed', 'exponential', 'normal', 'uniform', 'triangular'" validates_numericality_of :param1, :param2, :param3
def to_s "desc = " + desc + " param1 = " + param1.to_s + " dist_name = " + dist_name + " type = " + type.to_s end
protected def validate #desc can be fixed, exponential, normal, uniform, triangular errors.add("need 2nd parameter") if desc == 'normal' || desc == 'uniform' || desc == 'triangular' errors.add("need 3rd parameter") if desc == 'triangular' end
end
class LoadDist < Distribution
validates_uniqueness_of :dist_name, :scope => "load_id"
belongs_to :load end
class RscDist < Distribution validates_uniqueness_of :dist_name, :scope => "resource_id"
belongs_to :resource end
In my unit tests I can't seem to get a valid object. Here's my setup:
def setup @s1 = simulations(:base) @rsc1 = resources(:rsc1) @d1 = RscDist.new @d1.simulation_id = @s1.id @d1.resource_id = @rsc1.id end
and then the test:
def test_params_exp
@d1.desc = 'exponential'
assert !@d1.valid?
@d1.param1 = 14 @d1.dist_name = 'dist1' puts @d1.to_s assert @d1.valid? end
The final line "assert @d1.valid?" fails, even though I have a :desc field that is properly spelled, a numerical :param1, and a unique :dist_name. The message is:
1) Failure: test_params_exp(DistributionTest) [test/unit/distribution_test.rb:35:in `test_params_exp' c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.1.0/lib/active_support/testi ng/setup_and_teardown.rb:33:in `__send__' c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.1.0/lib/active_support/testi ng/setup_and_teardown.rb:33:in `run']: <false> is not true.
What am I doing wrong?
