Initial migration fails

[larsknausenberger]

Hi, thanks a lot for the tutorial :-)

I cloned the project to give it a try and stumbled upon an error when running the initial migration with

python manage.py migrate

This raised the following exception

django.db.utils.OperationalError: no such table: myapp_people

So I think the issue lies here:

tutorial-django-crispy-range-slider/myproject/src/myapp/filters.py

Lines 17 to 31 in dfebe9d

	class AllRangeFilter(RangeFilter):
	def __init__(self, *args, **kwargs):
	super().__init__(*args, **kwargs)
	values = [p.age for p in People.objects.all()]
	min_value = min(values)
	max_value = max(values)
	self.extra['widget'] = CustomRangeWidget(attrs={'data-range_min':min_value,'data-range_max':max_value})
	class PeopleFilter(FilterSet):
	age = AllRangeFilter()
	class Meta:
	model = People
	fields = ['age']
	form = PeopleFilterFormHelper

In line 26, the AllRangeFilter is instantiated. This causes a database query in line 20.

It seems like filters.py is imported when running the migration and thus the data base query is executed. I could work around the issue by temporarily commenting line 26.

Best regards,
Lars
