TypeError: can't use a string pattern on a bytes-like object

[sohimankotia]

Hi,

I am using python 3.4 and following code

from rejson import Client, Path

rj = Client(host='localhost', port=6379)

# Set the key `obj` to some object
obj = {
    'answer': 42,
    'arr': [None, True, 3.14],
    'truth': {
        'coord': 'out there'
    }
}
rj.jsonset('obj', Path.rootPath(), obj)

# Get something
response = rj.jsonget('obj', Path('.truth.coord'))
print (response.read().decode('utf-8'))

Value is getting inserted but while reading it is throwing following error

Traceback (most recent call last):
  File "/home/sohanvir/pyhton-workspace/rejsonDemo.py", line 16, in <module>
    response = rj.jsonget('obj', Path('.truth.coord'))

Solved . Hade to enable decode_response

rj = Client(host='localhost',port=6379,db=0,decode_responses=True)

Resolved my self .

I just came across this same error, it seems to me that on python3 Client should set decode_responses=True, having a bad default that makes the simplest jsonget fail isn't very nice.

from __future__ import print_function
from rejson import Client, Path
rj = Client()
# Set the key `obj` to some object
obj = {'answer': 42, 'arr': [None, True, 3.14], 'truth': {'coord': 'out there'}}
rj.jsonset('obj', Path.rootPath(), obj)
print(rj.jsonget('obj', Path('.truth.coord'))) # ok
print(rj.jsonget('obj', Path.rootPath())) # raises :(

@mmlb care to make a PR?

I don't think it's a good idea to close this issue, this kind of error will appear to all newcomers that use Python 3 and @mmlb is right the decode_responses=True should have been added as a default parameter. It's also not documented and that makes it even more difficult to figure out how to solve this problem when you try the rejson-py module for the first time.

👍 to this issue – it took me too long to find #8 (comment). I added decode_responses=True to the example in the README.
