ERR unknown command 'url'

[Anthony Scalisi]

Hi folks,

I'm testing Ohm with Sinatra and I'm running into an issue using redis-rb:

Ohm.redis = Redis.new(url: 'redis://127.0.0.1:6379/1', timeout: 2.0, driver: :hiredis)

class User < Ohm::Model
  attribute :first_name
end

class TestController < Sinatra::Base
      get '/new' do
        Ohm.redis.ping
        User.all
        # User.create(first_name: params['first_name'] )
      end
end

Redis logs:

1474582937.388670 [0 127.0.0.1:62349] "select" "1"
1474582937.388811 [1 127.0.0.1:62349] "ping"
1474582937.399781 [1 127.0.0.1:62349] "SMEMBERS" "User:all"

Sinatra logs:

127.0.0.1 - - [22/Sep/2016:15:22:17 -0700] "GET /new?first_name=antho HTTP/1.1" 200 - 0.0255

It appears to be working correctly until I uncomment User.create(first_name: params['first_name'] ):

1474583085.810329 [0 127.0.0.1:62624] "select" "1"

2016-09-22 15:24:45 - Redis::CommandError - ERR unknown command 'url':

Any ideas ? Thanks in advance for helping 🍶

[Michel Martens]

Hello @scalp42, sorry for the delay (I was on a trip). The Redis client has to be compatible with Redic in terms of API, which is not the case for redis-rb. Did you sorted it out?

[Michel Martens]

I'm closing this issue as using a different Redis client is not the intended use, but please reply to this thread so we can figure out what's best for your use case.
