it helps some times If you're going to send the parameter as a query param which are the params identified in a url after the ? character, then you'll need to access them via request.query_params. If you want to pass it through the url, then you should adjust your urls.py to:
code :
urlpatterns = [
    re_path(r'^get_board/(?P<pk>\d*)$', views.GetBoard.as_view(), name="get-board"),
]

To fix the issue you can do First thing first, let the DRF create the url's for you (this prevents misconfiguring the urls):
code :
from rest_framework.routers import DefaultRouter
router = DefaultRouter()
router.register(r'snippets', PersonViewSet)

urlpatterns = [
    ...
    url(r'^', include(router.urls)),
]
^persons/$ [name='person-list']
^persons\.(?P<format>[a-z0-9]+)/?$ [name='person-list']
^persons/blank_form/$ [name='person-blank-form']
^persons/blank_form\.(?P<format>[a-z0-9]+)/?$ [name='person-blank-form']
^persons/(?P<pk>[^/.]+)/$ [name='person-detail']
^persons/(?P<pk>[^/.]+)\.(?P<format>[a-z0-9]+)/?$ [name='person-detail']
class PersonViewSet(viewsets.ModelViewSet):
    """
    API endpoint that allows persons to be viewed or edited.
    """
    queryset = Person.objects.all().order_by('-date_joined')
    serializer_class = PersonSerializer
    template_name = 'common/rest_create.html'

    @list_route(renderer_classes=[renderers.TemplateHTMLRenderer])
    def blank_form(self, request, *args, **kwargs):
        serializer = PersonSerializer()
        return Response({'serializer': serializer})
{% load rest_framework %}

<html><body>    
<h1>New Person</h1>

<form action="{% url 'school:person-create' %}" method="POST">
    {% csrf_token %}
    {% render_form serializer %}
    <input type="submit" value="Save">
</form>

</body></html>

I wish this helpful for you This is how you pass the context to the serializer, if you are instantiating it manually.
serializer = MySerializer(data=data, context={'request': 'format': self.format_kwarg, self.request, 'view': self})

I think the issue was by ths following , I have implemented a test method which is like below: , You are passing as kwargs instead of args.
Replace this:
code :
request = self.factory.get(reverse('users:user-details', args=('d6cb0d1850241a04caaae516f27762d0c0cbc716',)))

it helps some times You can use viewsets instead of apiview for this purpose.
Here's an example.

may help you . Personaly I prefer use GenericAPIViews and the suitables mixins, is more verbose but I have more control over the REST action added, and I think it help to others developer that work with my projects.
For manage the rest documentation, you can use drf-yasg that allow tell the serializer for each method.
