新增 Neo4j 圖的關係

results = News.objects.todays_news()
for r in results:
    article = graph.merge_one("NewsArticle", "news_id", r)
    if 'LOCATION' in results[r].keys():
        for loc in results[r]['LOCATION']:
            loc = graph.merge_one("Location", "name", loc)
            try:
                rel = graph.create_unique(Relationship(article, "about_place", loc))
            except Exception, e:
                print e

create_unique 對於避免重複是很重要的。但除此之外它是一個相當簡單的操作。關係名稱也很重要，因為你可以在高階情況下使用它。
