Question

Can I filter a queryset based on a model field’s choices?

model:

COLORS = (
    ('BLACK', 'black'),
    ('RED', 'red'),
    ('BLUE', 'blue'),
    //etc..
)

class Thing(Models.model):
    color = models.CharField(max_length=5, choices=COLORS)

view:

def filter_by_color(request):
    q = Thing.objects.filter(???) 

Is there a way to filter Thing based on different color choices? Also, is there a way to write this dynamically, so that all color choices can respond to a single view?

Answer 1

Do you want this?

view

def filter_by_color(request, color):
     q = Thing.objects.filter(color=color)

So when you access http://yoursite/thisview/black you will get Things with black color and when you access http://yoursite/thisview/red you will get Things with red color .
