Add a slug field to models using the model mixin SearchSlugModelMixin. Specify the fields and/or properties to include in the slug in search_slug_fields:

class TestModel(SearchSlugModelMixin, models.Model):

    search_slug_fields = ['f1', 'f2', 'f3']

    f1 = models.CharField(max_length=25, null=True)
    f2 = models.DateTimeField(null=True)
    f3 = models.IntegerField(null=True)
    f4 = models.CharField(max_length=25, null=True)

Fields in the search_slug_fields are converted to string in the slug:

>>> obj = TestModel.objects.create(f1='run rabbit run!', f2=get_utcnow(), f3=12345)
>>> obj.slug
'run-rabbit-run!|2017-06-02 19:08:32.163520+00:00|12345'

Fields not listed are not included:

>>> obj = TestModel.objects.create(f1='slug me', f4='don\'t slug me')
>>> obj.slug
'slug-me||'

Null fields are converted to '':

>>> obj = TestModel.objects.create()
>>> obj.slug
'||'

You can use dotted syntax:

class TestModel(SearchSlugModelMixin, models.Model):

    search_slug_fields = ['f1', 'name.first', 'name.last']

    f1 = models.CharField(max_length=25, null=True)

    def name(self):
        return FullName(first='Gore', last='Vidal')

>>> obj = TestModel.objects.create()
>>> obj.slug
'|Gore|Vidal'
