<p>The channel handler, accessed from this module as CHANNEL_HANDLER is a
singleton that handles the stored set of channels and how they are
represented against the cmdhandler.</p>
<p>If there is a channel named ‘newbie’, we want to be able to just write</p>
<blockquote>
<div><p>newbie Hello!</p>
</div></blockquote>
<p>For this to work, ‘newbie’, the name of the channel, must be
identified by the cmdhandler as a command name. The channelhandler
stores all channels as custom ‘commands’ that the cmdhandler can
import and look through.</p>
<p>&gt; Warning - channel names take precedence over command names, so make
sure to not pick clashing channel names.</p>
<p>Unless deleting a channel you normally don’t need to bother about the
channelhandler at all - the create_channel method handles the update.</p>
<p>To delete a channel cleanly, delete the channel object, then call
update() on the channelhandler. Or use Channel.objects.delete() which
does this for you.</p>

just give the channel’s key or alias to write to it. Whenever a

<p>These methods will all return database objects (or QuerySets)

<p>A Channel is an in-game venue for communication. It’s essentially
representation of a re-sender: Users sends Messages to the

<p>Models for the in-game communication system.</p>
<p>The comm system could take the form of channels, but can also be
adopted for storing tells or in-game mail.</p>
<p>The comsystem’s main component is the Message (Msg), which carries the
actual information between two parties. Msgs are stored in the
database and usually not deleted. A Msg always have one sender (a
user), but can have any number targets, both users and channels.</p>
<p>For non-persistent (and slightly faster) use one can also use the
TempMsg, which mimics the Msg API but without actually saving to the
database.</p>
<p>Channels are central objects that act as targets for Msgs. Accounts can
connect to channels by use of a ChannelConnect object (this object is
necessary to easily be able to delete connections on the fly).</p>
