node.js - callback to handle completion of pipe -


I am using the following node. Js code to download documents from some URL and save it in disk. I should be informed about the document when the document has been downloaded. I have not seen any callback with pipes. Or is there any 'end' event that can be captured upon completion of the download? 

  request (some_url_doc) .pip (fs.createWriteStream ('xyz .doc'));    
 
 
 is the stream  EventEmitter  s so you can hear something . As you said, there is a  finish  event for the request (first  end ).  
  var stream = request (...). Pipe (...); Stream.on ('finish', function () {...});   
 For more information, you can test which incidents are available.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no.

Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
