ruby on rails - How to subscribe a Pubnub channel asynchronous? -

-

I want my rail app to subscribe to a global channel, so everything happens on the client, Will be published in I want it to be asynchronous because there will be a lot of messages through that channel, and I want to run it with the rail process. Currently, I can not get it to work, I can call it the initializers / pubnub Rb is inserted: 

  $ pubnub.subscribe (channel: 'global', callback: -> (envelope) {do_something})

I do not get any incoming messages.

Just one usage example in my test app: 

  $ pubnub = Pubnub.new (: subscribe_key = & gt; "demo" ,: publish_key => demo ",: heartbeat => 10,: logger = & gt; Rails.logger) ActiveRecord :: base.establish_connection $ pubnub .subscribe (: channel = & gt;: demo) {| e | Message.create (: content => e.msg)}

This works just fine. Trying to run the code in the callback?

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
