Rails 3.0.3 has many#create does not create a record

Reported by Rob Westgeest | January 22nd, 2011 @ 10:55 AM

Given a these models

class OrganizingCity < ActiveRecord::Base
  has_many :tables
end
class Table < ActiveRecord::Base
  belongs_to :organizing_city
end

and the specs (using FixtureReplacement)

describe OrganizingCity do
  describe "create a table" do
    it "through tables#create add a table to the has_many association" do
      organizing_city = create_organizing_city
      organizing_city.tables.create new_table.attributes
      organizing_city.reload
      organizing_city.tables.size.should == 1
    end
    it "through creating a new table adds a table to the has many association" do
      organizing_city = create_organizing_city
      Table.create organizing_city.tables.create new_table(:organizing_city => organizing_city).attributes
      organizing_city.reload
      organizing_city.tables.size.should == 1
    end
  end
end

then the first one fails and the second one passes.

    This won't be a Rails problem. Its likely that new_table.attributes is returning a hash which has a key :organizing_city_id with a value of nil, causing the table to get saved without the foreign key.

    You're right!. changing the first spec to:

        it "through tables#create add a table to the has_many association" do
      organizing_city = create_organizing_city
      table_attributes = new_table.attributes
      table_attributes.delete "organizing_city_id"
      organizing_city.tables.create table_attributes
      organizing_city.reload
      organizing_city.tables.size.should == 1
    end

    makes it pass.

    Sorry to have poluted this list with a worthless ticket. This can be closed.
