I want to use the ruby redis client to subscribe to a channel. When subscription was successful I want to start an ActiveJob (Sidekiq is used) job using perform_later. This Job will then do some work and produce a result which will be published to the channel Redis channel.This produces the following error:
Processing by Api::LocationController#yyy as */* Parameters: {"zip_code"=>"503400"}[ActiveJob] Failed enqueuing XXXJob to Sidekiq(default): NoMethodError (undefined method `call_pipeline' for #<Redis::SubscribedClient:0x00007fd9222cdf78 @client=#<Redis::Client:0x00007fd921e1b890 @options={:url=>"redis://localhost?db=xxx", :scheme=>"redis", :host=>"localhost", :port=>6379, :path=>nil, :read_timeout=>0, :write_timeout=>5.0, :connect_timeout=>5.0, :timeout=>5.0, :username=>nil, :password=>nil, :db=>0, :driver=>Redis::Connection::Ruby, :id=>nil, :tcp_keepalive=>0, :reconnect_attempts=>1, :reconnect_delay=>0.0, :reconnect_delay_max=>0.5, :inherit_socket=>false, :logger=>nil, :sentinels=>nil, :role=>:master, :_parsed=>true}, @reconnect=true, @logger=nil, @connection=#<Redis::Connection::Ruby:0x00007fd921df08c0 @sock=#<Redis::Connection::TCPSocket:fd 26>>, @command_map={}, @pending_reads=-3, @connector=#<Redis::Client::Connector:0x00007fd921e1a2d8 @options={:url=>"redis://localhost?db=xxx", :scheme=>"redis", :host=>"localhost", :port=>6379, :path=>nil, :read_timeout=>5.0, :write_timeout=>5.0, :connect_timeout=>5.0, :timeout=>5.0, :username=>nil, :password=>nil, :db=>0, :driver=>Redis::Connection::Ruby, :id=>nil, :tcp_keepalive=>0, :reconnect_attempts=>1, :reconnect_delay=>0.0, :reconnect_delay_max=>0.5, :inherit_socket=>false, :logger=>nil, :sentinels=>nil, :role=>:master, :_parsed=>true}>, @pid=54943>>)Completed 500 Internal Server Error in 26ms (Allocations: 2374)NoMethodError (undefined method `call_pipeline' for #<Redis::SubscribedClient:0x00007fd9222cdf78 @client=#<Redis::Client:0x00007fd921e1b890 @options={:url=>"redis://localhost?db=xxx", :scheme=>"redis", :host=>"localhost", :port=>6379, :path=>nil, :read_timeout=>5.0, :write_timeout=>5.0, :connect_timeout=>5.0, :timeout=>5.0, :username=>nil, :password=>nil, :db=>0, :driver=>Redis::Connection::Ruby, :id=>nil, :tcp_keepalive=>0, :reconnect_attempts=>1, :reconnect_delay=>0.0, :reconnect_delay_max=>0.5, :inherit_socket=>false, :logger=>nil, :sentinels=>nil, :role=>:master, :_parsed=>true}, @reconnect=true, @logger=nil, @connection=#<Redis::Connection::Ruby:0x00007fd921df08c0 @sock=nil>, @command_map={}, @pending_reads=-3, @connector=#<Redis::Client::Connector:0x00007fd921e1a2d8 @options={:url=>"redis://localhost?db=xxx", :scheme=>"redis", :host=>"localhost", :port=>6379, :path=>nil, :read_timeout=>5.0, :write_timeout=>5.0, :connect_timeout=>5.0, :timeout=>5.0, :username=>nil, :password=>nil, :db=>0, :driver=>Redis::Connection::Ruby, :id=>nil, :tcp_keepalive=>0, :reconnect_attempts=>1, :reconnect_delay=>0.0, :reconnect_delay_max=>0.5, :inherit_socket=>false, :logger=>nil, :sentinels=>nil, :role=>:master, :_parsed=>true}>, @pid=54943>>):app/controllers/api/location_controller.rb:10:in `block (3 levels) in yyy'app/controllers/api/location_controller.rb:8:in `block in yyy'app/controllers/api/location_controller.rb:5:in `yyy'The yyy function is part of a controller that gets called on a GET request:
def yyy REDIS_POOL.with { |r| data = r.get("key") if data.nil? r.subscribe("channel") { |on| on.subscribe { XXXJob.perform_later(params) } on.message { |_, message| puts message render json: message r.unsubscribe("channel") } } else render json: data end } endIt seems to me like there's some context being lost from the Redis subscribe block which is important for the perform_later function. The same code works if I move the XXXJob.perform_later(params) call above the r.subscribe("channel") call and thus outside of the block. I however want to make sure that the job is only started after the subscription to the Redis channel was successful. Is there any way to achieve this?
