Installation

installation is simple

pip install lfs-criterion-extra

or

pip install git+https://github.com/suvit/lfs-criterion-extra

After instalation of the package you should add lfs_criterion_extra to INSTALLED_APPS before lfs app. This is because, this app overwrite lfs templates.

After that you needed to add tables in db

python manage.py syncdb

That`s all.

• ManualDeliveryTimeCriterion

• FullUserCriterion (AdvancedUserCriterion)

You may choose new criterions from criterion`s tab of delivery and payment methods.

Added own criterions

You may inherit Criterion or NumberCriterion

from lfs_criterion_extra.models import Criterion, NumberCriterion

class FooCriterion(NumberCriterion):

foo = models.DecimalField(‘FOO’)

‘may be other model fields’

value_attr = ‘foo’ # from that attribute get value to compare content_type = ‘foo’ # internal id of the criterion name = ‘Foo’ # displayable value

def is_valid(self, request, product=None):

how_many_foo = product.name.count(‘foo’) return self.test_value(how_many_foo)

that`s all, your criterion is appeared in the criterion list.

TODO

• move monkey.py to lfs.criterion.core (merge or move to lfs 0.8)

• write tests
