def fixture(fixture_name)
  @fixtures ||= {}
  fixture = @fixtures[fixture_name]
  if fixture
    fixture
  else
    @fixtures[fixture_name] = instantiate_from_fixture(Fixie.fixture(fixture_db_name, fixture_table_name, fixture_name))
  end
end

#fixture_db_name ⇒ Symbol

This method determines which database is used to load the fixture. The default implementation is to check the class to see if it has a namespace, like ‘Foo::Bar’, and if it does, return :foo. If it does not have a namespace, it will return :default.

You should override this method if you have multiple databases in your app and you have a different way of determining the DB name based on the class.

Returns:

  • (Symbol) —

    The db name for this class

    match_data[1].to_sym
  else
    :default
  end
end

#fixture_table_name ⇒ Symbol

This method returns the name of the table that the fixtures for this model should be loaded into/from. The default is to just underscore and pluralize the table name, e.g. City => cities.

Returns:

  • (Symbol) —

    The table name for this class

  end
end

#instantiate_from_fixture(fixture) ⇒ Object

This method is used to get an instance of the model from a fixture hash. The default implementation is to just pass the hash to the model’s constructor.

Parameters:

  • fixture (Hash<String, Object>) —

    The fixture

Returns:

  • (Object) —

    An instance of this class
