how to use aliases in graphene-django

Question

I'm using python 3.5 with

Django==1.11.6
graphene==2.0.dev20170802065539
graphene-django==2.0.dev2017083101
graphql-core==2.0.dev20171009101843
graphql-relay==0.4.5

I have a schema that fetch's single objects like this:

class Query(graphene.AbstractType):
   story = graphene.Field(storyType, category=graphene.String(), id=graphene.Int())
   def resolve_story(self, info, **kwargs):
        category = kwargs.get('category')
        id = kwargs.get('id')
        if category is not None:
            return models.story.objects.get(category=models.category.objects.get(name=category))
        if id is not None:
            return models.story.objects.get(pk=id)
        return None

My problem is that I can't use both story(category:"category") and (id:"id") in one query. I read here that I should use aliases but I don't know how. Thank's for any help.

Is as simple as the example just:

{
  storyId: story(id: 1) {
    name
  }
  storyCategory: story(category: "category_name") {
    name
  }
}

but you can use filter if that is what you mean doing something like:

        if category and id is not None:
            return models.story.objects.filter(id=id, category=models.category.objects.get(name=category))

and in the query something like:

story(id: 1, name: "category_name") {
        name
      }
