Save Python dict to Redis hash

dict_to_redis.py

def dict_to_redis_hset(r, hkey, dict_to_store):
    """
    Saves `dict_to_store` dict into Redis hash, where `hkey` is key of hash.

    >>> import redis

    >>> dict_to_redis_hset(r, 'test', d)

Just learning redis now but wouldn't you want a pipeline here?

hey!
please upload the definition of the function dict_to_redis_hset

hmset is deprecated

Given that hmset is deprecated, for dictionaries we can use hset, like this (do not skip the named mapping arg):

r.hset(hkey, mapping=dict_to_store)

See in redis-py docs.

Does anyone know how to store a dict value? I get this error when I try to map a key to a dict value

DataError: Invalid input of type: 'dict'. Convert to a bytes, string, int or float first.

If someone notices that even with mapping attribute you get DataError: Invalid input of type: 'dict'. Convert to a bytes, string, int or float first. when trying to set dict as value, check that values inside the dict are also ints, bytes or strs. I was trying to hset with ...mapping={'mapping': {'nested_mapping': 'which i have not noticed'}}
