                    <description>&lt;p&gt;Right now, you can only do a $set on an update.  It would be helpful to be able to delete or rename a field as well.&lt;/p&gt;</description>

&lt;p&gt;$unset : &lt;/p&gt;
{ &apos;comments.5&apos;  : TRUE }</comment>
                            <comment id="10236" author="wouter" created="Wed, 8 Jul 2009 11:03:13 +0000"  >&lt;p&gt;I would like $unset/$rename too.&lt;/p&gt;

&lt;p&gt;Let&apos;s say we have &lt;/p&gt;
{ _id : 1, toberemoved : &apos;hello&apos;, dontremove : 
&apos;world&apos; }
&lt;p&gt; &lt;/p&gt;

&lt;p&gt;1) $db.foo.save( &lt;/p&gt;
{ _id : 1, dontremove : &apos;world&apos; }
&lt;p&gt;); &lt;br/&gt;
Could have concurrency issues. &lt;/p&gt;

&lt;p&gt;2) $db.foo.update( &lt;/p&gt;
{ _id : 1, toberemoved : &apos;hello&apos;, dontremove : 
&apos;world&apos; }
&lt;p&gt;, &lt;/p&gt;
{ _id : 1, dontremove : &apos;world&apos; }
&lt;p&gt; ); &lt;br/&gt;
Will fail if another process already changed the object. &lt;/p&gt;

&lt;p&gt;3) $db.foo.update( &lt;/p&gt;
{ _id : 1 }
&lt;p&gt;, { $unset : &lt;/p&gt;
{ toberemoved : 1 }
&lt;p&gt; } ); &lt;br/&gt;
This will never fail nor have any concurrency issues &lt;del&gt;ideal behavior&lt;/del&gt;, &lt;/p&gt;</comment>
