@step(STEP_PREFIX<EOL>+ r'<STR_LIT>')<EOL>def _model_exists_positive_step(self, model):
return _model_exists_step(self, model, True)<EOL>
Test for the existence of a model matching the given data.

Column names are included in a query to the database. To check model
attributes that are not database columns (i.e. properties) prepend the
column with an ``@`` sign.

Example:

.. code-block:: gherkin

    Then foos should be present in the database:
        | name   | @bar |
        | badger | baz  |
