python中mongodb的list查詢
阿新 • • 發佈:2018-12-26
這裡topic_question中的topic_list是一個數組,需要查詢topic_list中匹配給定兩個元素的條目
listf=list() results = db.topic_questions.find({'$and': [{'topic_list':source}, {'topic_list': target}]}) for result in results: listf.append({'question': result['title'], 'answers_count': result['answers_count']})
