slack-bot-server's Issues

I'm having to repeat the RemoteControl.new command in the console

I'm able to successfully add a bot to the server and broadcast a message using slack_remote from the console, however I always get an error the first time I use this command in the console:
slack_remote = SlackBotServer::RemoteControl.new(queue: queue)

This is not a critical problem, and it may not be related to the gem. If I repeat the command immediately after it failed, then it works. Here's the console output showing it working:

$ require 'slack_bot_server'
  => true
$ reload!
  Reloading...
  => true 
$ queue = SlackBotServer::RedisQueue.new(Redis.new)
  => #<SlackBotServer::RedisQueue:0x007ff6b3278b50 @key="slack_bot_server:queue", @redis=#<Redis client v3.2.2 for redis://127.0.0.1:6379/0>> 
$ slack_remote = SlackBotServer::RemoteControl.new(queue: queue)

$ slack_remote = SlackBotServer::RemoteControl.new(queue: queue)

$ slack_remote.add_token('the-token-goes-here')
  => 1
$ slack_remote.say('the-token-goes-here', text: 'I have an important announcement to make!')
  => 1

Having to repeat the command is not what I'd expect. Does this indicate that anything is wrong with the gem or with how I've set up this app?

In case it's helpful, here's remote_control.rb:

class SlackBotServer::RemoteControl
  def initialize(queue:)
    @queue = queue
  end

  def add_token(token)
    @queue.push([:add_token, token])
  end

  def remove_bot(key)
    @queue.push([:remove_bot, key])
  end

  def broadcast(key, message_data)
    @queue.push([:broadcast, key, message_data])
  end

  def say(key, message_data)
    @queue.push([:say, key, message_data])
  end

  def say_to(key, user_id, message_data)
    @queue.push([:say_to, key, user_id, message_data])
  end

  def call(key, method, args)
    @queue.push([:call, [key, method, args]])
  end
end

Question about slack-bot-server on Heroku

If this is the Procfile in a Rails app on Heroku...

web: bundle exec puma -C config/puma.rb
worker: bundle exec rake jobs:work
slack_server: bundle exec rails runner bin/slack_server

...then for every Heroku Dyno that spins up, it will have a slack-bot-server instance too, I believe. Is that redundant because there will be multpile slack-bot-servers monitoring each of the Slack teams?

I guess I could stand up slack-bot-server on its own dyno as a separate app, but I'd like to keep it connected to the main Rails app. Any other suggestions?

Logging hooks

suggestion / question

We've started using the slack-bot-server in our product and really like what it does. One improvement I wanted to make was to have it log unhandled exceptions to an error logging component or service of choice, and being able to configure that. At the moment, the only thing the server does is writing errors to the log.

To workaround, I monkey patched the log_error method like below.

module SlackBotServer::Logging
  def log_error(e, *args)
    message = "#{e} - #{e.message}"
    message += " (#{log_string(*args)})" if args.any?

    # note I changes the log levels from the defaults here as well.
    SlackBotServer.logger.error("#{message}")
    SlackBotServer.logger.debug(e.backtrace.join("\n"))

    # do custom error reporting/handling here.
    Rollbar.error(e, message)
  end
end

I went this route after looking at extending the gem sources in a way to make this less of a patch. But I didn't get to a solution that I felt good enough to submit a pull request.

Alternatives I tried were along the same line as what the gem does today in allowing you to override the SlackBotServer.logger or how you allow on_add and other hooks.

Has this been considered? Suggestions?

Based on feedback I'll be happy to work on what I started some more and submit a PR.

Cannot use `call` command

I am trying to use https://github.com/exciting-io/slack-bot-server/blob/master/lib/slack_bot_server/remote_control.rb#L57. My invocation looks like:

server.call(key, 'users.list', [])

When process_instruction handles this, the following occurs:

    1: class SlackBotServer::Server
    2:   def process_instruction(instruction)
 => 3:     binding.pry
    4:     type, *args = instruction
    5:     bot_key = args.shift
    6:     if type.to_sym == :add_bot
    7:       log "adding bot: #{bot_key} #{args.inspect}"
    8:       add_bot(bot_key, *args)

[1] pry(#<SlackBotServer::Server>)> instruction
=> ["call", ["XXX", "users.list", []]]
[2] pry(#<SlackBotServer::Server>)> type, *args = instruction
=> ["call", ["XXX", "users.list", []]]
[3] pry(#<SlackBotServer::Server>)> args
=> [["XXX", "users.list", []]]
[4] pry(#<SlackBotServer::Server>)> args.shift
=> ["XXX", "users.list", []]

The entire array content is being used for bot_key rather than just the key part of it. The call command fails due to this.

I'm using ruby 2.3.1.

Failing test in circleci

when i run rspec error comes

Server crashes on boot-up when bad token is included.

Using the advanced example, we loop through the bot tokens in our database and add them before the server starts. However, if there is a bad token, the whole server crashes. The server should instead log a warning for the bad token, and continue to boot.

Code

queue = SlackBotServer::RedisQueue.new

server = SlackBotServer::Server.new(queue: queue)

server.on_add do |token|
  VinnyBot.new(token: token)
end

User.find_each do |user|
  server.add_bot(user.bot_token) if user.bot_token.present?
end

server.start

Gaps in the README

After a bit of messing around I was finally able to get this working. A few things that seem to be missing in the documentation/README:

I had to manually require the library in my gemfile gem 'slack-bot-server', :require => 'slack_bot_server'
It looks like the library is dependent on the redis gem, but not included in the libraries Gemfile so I needed to add that to my Gemfile as well gem 'redis'
in order to access the remote control library I had to first manually require it require 'slack_bot_server/remote_control'
in order to retrieve a bot token I need to include the bot scope when authenticating with Slack
in order to send messages from my bot I need to include the chat:bot:write scope
in order to use the remote control say feature I needed to provide a channel with :channel => 'some-channel-name'

Redis::CannotConnectError: Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED)

queue = SlackBotServer::RedisQueue.new(redis: Redis.new)
slack_remote = SlackBotServer::RemoteControl.new(queue: queue)
slack_remote.add_bot('user-accounts-slack-api-token')

when i try to add_bot then above error comes on heroku but it is working fine in local please help

interactive message support

I plan to use this as my bot server but I would need interactive message support.

How would I be able to support that? If you don't have time to do it yourself, could you point some way and I will try to add it, it is important for me that I can do interactive messages.

Talking to main app

Hey guys,

Slack-bot-server is exactly what I've been looking for! Awesome work :)

I'm trying to figure out how I can interact with my main app from inside of slack-bot-server. At the moment I have my code living in lib/slackbots/ and I load it via forman with slackbot: ./lib/slack-bot-server.

Do you have any suggestions on how I would do it?

Cheers

Josh

Error with using 'reply' in the on :message block

Hi,

I got an error when I try to use the on :message hook.

I, [2016-03-30T01:46:44.693127 #2228]  INFO -- : [BOT/bot] {:error=>#<NoMethodError: undefined method `[]' for nil:NilClass>}
I, [2016-03-30T01:46:44.693604 #2228]  INFO -- : [BOT/bot] {:backtrace=>["/Users/K/.rvm/gems/ruby-2.2.1/gems/slack-bot-server-0.4.2/lib/slack_bot_server/bot.rb:116:in `reply'",

Inside my bot class, I did this:

  on(:message) do |data|
    reply text: "Hello."
  end

It looks like the @last_received_data in the reply method (line 116 in bot.rb) is nil for some reason. Any idea what's wrong here?

Support to handle file uploads in IM

My bot will handle files that get sent to the bot in IM, and now it gives an error message when I send a file to the bot.

Help getting started

After fixing the gem name, I got the server up and running, but I can't get it to recognise a bot

Unknown bot: XXXX-21908568258-mgPBY9xwF9xdhHzF7q1n602E

This is (obfuscated above) a valid Bot token in slack - but just throws this error

The problem is made slightly trickier by not having a any 'good' way to debug - putting puts or debugger in the .on method doesnt get hit - it seems to fail long before that proc is even called

Any suggestions here?

edit: probably should add, running under Rails 4.2, with spring stop;bin/rails runner bin/slack_server
edit: using the sample bot SimpleBot and sample SlackServer

Replace slack-api with slack-ruby-client, remove need for web API

The implementation of say is using the web client, which is wasteful at the very least. Replace the underlying library with https://github.com/dblock/slack-ruby-client, and reimplement say to use the websocket connection.

Questions about How to Use

Hello, thanks for writing this gem.

I'm looking through the documentation and these are the questions that come to mind:

To use Foreman to start the SimpleBot server, I'm assuming we add a line to the Procfile. What would that line look like?
For the Advanced Example to work, do we have to install anything extra such as a Gem to make Harmonia work? In other words, what is this connecting to...

require 'harmonia/slack_bot'

Handle migration_in_progress error from Slack

Slack can respond to rtm.start with migration_in_progress error, slack-bot-server should handle this error.

Looks like the best option is to wait 1 second and try to reconnect.

Example from slack-ruby-bot
https://github.com/dblock/slack-ruby-bot/blob/6ab072fbf1e34f05f5d6ea3e55cd5185b1f39769/lib/slack-ruby-bot/server.rb#L25

Bot keeps disconnecting and reconnecting twice

Hey,
First, thank you for implementing this awesome library 👍

Somehow my Slackserver is quite unstable. I keep getting disconnects (which is fine by itself), but after that, TWO Bots connect. So every incoming message is getting processed twice by my system. And this effect keeps stacking, so I ended up with 7 connections sometimes, that then lead to the Too Many requests� API error.
I stumbled upon slack-ruby/slack-ruby-client@9934f02 but not sure if related.

Do you have an idea how to fix this?

Thank you,
Mirko

Versions

Using slack-ruby-client 0.14.2
Using slack-bot-server 0.4.7

Extend docs to explain how to use an Add to Slack button with slack-bot-server

The docs have a brief passage re: creating a Slack App, but it doesn't provide hints on what needs to be added to our applications to get an Add to Slack button to work. The docs of slack-bot-server don't seem to explain from where we're supposed to get team tokens.

Presumably we'd need an endpoint in our greater application where the auth code can be posted and then use a Slack::Web::Client#oauth_access to get the token.

(BTW, slack-ruby-bot-server has this built-in … but it's dependencies on Mongo make it a non-starter – I know they're trying to abstract that out though)

Error w/ slack-api gem's faye-websocket dependency

I got this gemfile conflict:

slack-bot-server (>= 0) ruby depends on
    slack-api (>= 1.1) ruby depends on
        faye-websocket (~> 0.9.2) ruby

slack-ruby-client (>= 0) ruby depends on
    faye-websocket (0.10.1)

I forked the slack-ruby gem at https://github.com/LucasCioffi/slack-ruby-gem/blob/dev/slack.gemspec and changed the faye dependency:

"faye-websocket", ">= 0.9.2"

I tried including this fork of the slack-ruby gem into my fork of slack-bot-server at https://github.com/LucasCioffi/slack-bot-server/blob/master/slack_bot_server.gemspec but this format didn't work for specifying the git source:

spec.add_dependency "slack-api", :git => "https://github.com/LucasCioffi/slack-ruby-gem"

...so then I commented it out and manually included the files in this order in my gemfile:

gem "slack-api", :git => "https://github.com/LucasCioffi/slack-ruby-gem"
gem 'slack-bot-server', :git => 'https://github.com/LucasCioffi/slack-bot-server'

The error is gone, but this is a suboptimal solution. Anything else that can be done?
