[Answered ]-How to limit choices to Foreign keys in Django admin

To filter statuses by project, you need your story to already exist so django know which project we are talking about. If you set status nullalble, you can do like this (implying, you do save and continue on first save to set status)

class StatusAdmin(admin.ModelAdmin):
    def get_form(self, request, obj=None, **kwargs):
        form = super(StatusAdmin, self).get_form(request, obj, **kwargs)
        if obj and obj.project:
            form.base_fields['status'].queryset = \
                form.base_fields['status'].queryset.filter(project=obj.project)
        elif obj is None and 'status' in form.base_fields: # on creation
            del form.base_fields['status']
        return form
