我想把异步工作变成同步的。我使用couchbase中数据的id作为redis中的键。我再次upsert couchbase并将redis的值作为其值。当以同步方式运行时，它运行良好，但异步执行时会失败。"最初的回答"

cluster.authenticate(authenticator)
bucket_test = cluster.open_bucket('ATLAS-DEV')
redis_db = redis.StrictRedis(host='--', port=6379, db=10, decode_responses=True)
map_api = osmapi.OsmApi()
N1QLQuery.timeout = 3600
def deep_get(dictionary, keys, default=None):
return reduce(lambda d, key: d.get(key, default) if isinstance(d, dict) else default, keys.split("."), dictionary)
query = N1QLQuery("SELECT meta().id, * FROM `ATLAS-DEV` WHERE class_type = 'REGION' AND (codes.osm IS NOT NULL OR codes.osm != '') LIMIT 20")
for k in bucket_test.n1ql_query(query):
# print("k : ")
# print(k)
document_id = k.get("id")
# print("document_id : " + document_id)
osm_id = deep_get(k, "ATLAS-DEV.codes.osm")
polygon = redis_db.hget(name="osm:polygons", key=osm_id)
if polygon is not None:
k['ATLAS-DEV'].update({'boundaries': polygon})
bucket_test.upsert(document_id, k['ATLAS-DEV'])
这是我的同步工作。它运行良好，可以插入/更新Couchbase。
但是这里是我的Celery作业代码。
from app.jobs.task import each_k
query = N1QLQuery("SELECT meta().id, * FROM `ATLAS-DEV` WHERE class_type = 'REGION' AND (codes.osm IS NOT NULL OR codes.osm != '') LIMIT 5")
for k in bucket_test.n1ql_query(query):
# print("k : ")
# print(k)
each_k.delay(k)
# /app/jobs/task.py
def deep_get(dictionary, keys, default=None):
return reduce(lambda d, key: d.get(key, default) if isinstance(d, dict) else default, keys.split("."), dictionary)
@app.task
@provide_redis
def each_k(redis_db, k):
print("레디스 디비 : ")
print(redis_db)
document_id = k.get("id")
print("document_id : " + document_id)
osm_id = deep_get(k, "ATLAS-DEV.codes.osm")
polygon = redis_db.hget(name="osm:polygons", key=osm_id)
print("폴리곤 : ")
print(polygon)
if polygon is not None:
k['ATLAS-DEV'].update({'boundaries': polygon})
bucket_test.upsert(document_id, k['ATLAS-DEV'])
