Get single record on Django Rest Framework based on id

I am getting the following response from my REST API at http://127.0.0.1:8000/api/category/:

[
    {
        "id": "17442811-3217-4b67-8c2c-c4ab762460d6",
        "title": "Hair and Beauty"
    },
    {
        "id": "18a136b5-3dc4-4a98-97b8-9604c9df88a8",
        "title": "Plumbing"
    },
    {
        "id": "2f029642-0df0-4ceb-9058-d7485a91bfc6",
        "title": "Personal Training"
    }
]

If I wanted to access, a single record, I presume that I would need to go to http://127.0.0.1:8000/api/category/17442811-3217-4b67-8c2c-c4ab762460d6 to access:

[
    {
        "id": "17442811-3217-4b67-8c2c-c4ab762460d6",
        "title": "Hair and Beauty"
    }
]

However, when I attempt this, it returns all of the records. How can I resolve this? This is my code so far:

urls.py

urlpatterns = [
    url(r'^category/', views.CategoryList.as_view(), name="category_list"),
    url(r'^category/?(?P<pk>[^/]+)/$', views.CategoryDetail.as_view(), name="category_detail")
]

views.py

class CategoryList(generics.ListAPIView):
    """
    List or create a Category
    HTTP: GET
    """
    queryset = Category.objects.all()
    serializer_class = CategorySerializer


class CategoryDetail(generics.RetrieveUpdateDestroyAPIView):
    """
    List one Category
    """
    serializer_class = CategorySerializer

serializers.py

class CategorySerializer(serializers.ModelSerializer):
    """
    Class to serialize Category objects
    """
    class Meta:
        model = Category
        fields = '__all__'
        read_only_fields = ('id')

models.py

class Category(models.Model):
    """
    Category model
    """
    id = models.UUIDField(primary_key=True, default=uuid4, editable=False)
    title = models.CharField(max_length=255)

    def __str__(self):
        return "%s" % (self.title)

Your first regex, r'^category/', matches both a URL with and without a UUID.

You should anchor it at the end:

r'^category/$'

Additionally/alternatively, you can swap the order of those URL definitions, as Django will take the first one it matches.
