In the toward examples we just pass a ``package`` parameter to
:func:`~pyramid_formalchemy.configure`. By default the function will try to
load ``package.models`` ``package.models.DBSession`` and ``package.forms`` but

Custom views per model
----------------------
You can also register custom CRUD views per ModelListing::
config.formalchemy_model_view('admin',
model='pyramidapp.models.Foo',
context='pyramid_formalchemy.resources.ModelListing',
renderer='templates/foolisting.pt',
attr='listing',
request_method='GET',
permission='view')

model='pyramidapp.models.Foo',
context='pyramid_formalchemy.resources.Model',
name='',
renderer='templates/fooshow.pt',
attr='show',
