Question

只需测试wagtaildemo，在本地ubuntu pc上使用runserver命令就可以运行良好。

在文件“wagtaildemo / demo / wagtail_hooks.py”中找到了@ hook.regist decorate函数，但是在admin site lest tab和其他地方没有找到函数入口。为什么呢？

var Server = require('bittorrent-tracker').Server

var server = new Server({
  udp: true, // enable udp server? [default=true]
  http: true, // enable http server? [default=true]
  ws: true, // enable websocket server? [default=true]
  stats: true, // enable web-based statistics? [default=true]
  filter: function (infoHash, params, cb) {
    // Blacklist/whitelist function for allowing/disallowing torrents. If this option is
    // omitted, all torrents are allowed. It is possible to interface with a database or
    // external system before deciding to allow/deny, because this function is async.

    // It is possible to block by peer id (whitelisting torrent clients) or by secret
    // key (private trackers). Full access to the original HTTP/UDP request parameters
    // are available in `params`.

    // This example only allows one torrent.

    var allowed = (infoHash === 'aaa67059ed6bd08362da625b3ae77f6f4a075aaa')
    if (allowed) {
      // If the callback is passed `null`, the torrent will be allowed.
      cb(null)
    } else {
      // If the callback is passed an `Error` object, the torrent will be disallowed
      // and the error's `message` property will be given as the reason.
      cb(new Error('disallowed torrent'))
    }
  }
})

// Internal http, udp, and websocket servers exposed as public properties.
server.http
server.udp
server.ws

server.on('error', function (err) {
  // fatal server error!
  console.log(err.message)
})

server.on('warning', function (err) {
  // client sent bad data. probably not a problem, just a buggy client.
  console.log(err.message)
})

server.on('listening', function () {
  // fired when all requested servers are listening
  console.log('listening on http port:' + server.http.address().port)
  console.log('listening on udp port:' + server.udp.address().port)
})

// start tracker server listening! Use 0 to listen on a random free port.
server.listen(port, hostname, onlistening)

// listen for individual tracker messages from peers:

server.on('start', function (addr) {
  console.log('got start message from ' + addr)
})

server.on('complete', function (addr) {})
server.on('update', function (addr) {})
server.on('stop', function (addr) {})

// get info hashes for all torrents in the tracker server
Object.keys(server.torrents)

// get the number of seeders for a particular torrent
server.torrents[infoHash].complete

// get the number of leechers for a particular torrent
server.torrents[infoHash].incomplete

// get the peers who are in a particular torrent swarm
server.torrents[infoHash].peers

正如docs所说：

钩

加载时，Wagtail将搜索包含该文件的任何应用程序   wagtail_hooks.py并执行内容。这提供了一种方法   注册你自己的函数在Wagtail的某些点执行   执行，例如保存Page对象或主菜单时   是建造的。

因此，此函数是一个钩子，它在创建管理编辑器页面时执行，并将一个link标记添加到CSS文件以对流场进行样式化。 insert_editor_css hook会插入其他CSS文件或片段。

@ hook.regist装饰不起作用
