Install bot to a team event

[vovanmozg]

I need to send initial message to the user after adding my application to his team.
I solve this problem with is monkey patching of the file https://github.com/dblock/slack-bot-server/blob/22a215eec2/slack-bot-server/api/endpoints/teams_endpoint.rb after team activating

# == My code start ==
SlackBotServer::Service.start!(team)

client.token = rc['access_token']
information = client.auth_test({token: rc['access_token']})

client2 = Slack::Web::Client.new(token: token)
# always try to create new DM
new_dm = client2.im_open(user: information[:user_id])
channel_id = new_dm.channel.id

# send message
client2.chat_postMessage(
  channel: channel_id,
  text: "Hello <@#{information[:user_id]}>. Nice to meet you! Type 'help'",
  as_user: true
)

client2 = nil
# == My code end ==

Is there right way, to send message to user immediately after he install the bot? Can you give me advice on how to do better, or leave like that?

thanks

I don't think there's a "right" way at this point. You probably want to do this in a callback after a connection has been established the first time on start, to avoid re-creating a connection twice, then remember that you sent a welcome message. But this works too.

I'll leave this open, I'd like an "official" way of doing this, but probably mostly in https://github.com/dblock/slack-ruby-bot.

I've implemented lifecycle callbacks in dblock@325eb94 and dblock@3bfcb30. You should be able to do this:

instance = SlackRubyBotServer::Service.instance

instance.on :created do |team, server, error|
  server.client....
end

I think we need to make .client public in slack-ruby-bot. There's a discussion about this in https://github.com/dblock/slack-ruby-bot/issues/63, would love a PR.

Give it a try?
