{% if somevalue %}
  {{form.fieldname}} #<---- how do i set the `somevalue` as value of fieldname here?

In your view, if it is a class-based view, do it like so:

class YourView(FormView):
    form_class = YourForm

    def get_initial(self):
        # call super if needed
        return {'fieldname': somevalue}

If it is a generic view, or not a FormView, you can use:

form = YourForm(initial={'fieldname': somevalue})
