You&nbsp;should&nbsp;implement&nbsp;the&nbsp;resource_exists()&nbsp;callback;&nbsp;this&nbsp;will&nbsp;let&nbsp;the&nbsp;rest&lt;br&gt;<br>
module&nbsp;pick&nbsp;a&nbsp;200&nbsp;vs&nbsp;201. &nbsp;If&nbsp;the&nbsp;db&nbsp;name&nbsp;was&nbsp;incorrect,&nbsp;I&nbsp;think&nbsp;you&nbsp;are&lt;br&gt;<br>

Hi&nbsp;all,&lt;br&gt;<br>
&lt;br&gt;<br>
1.&nbsp;I&nbsp;would&nbsp;like&nbsp;to&nbsp;use&nbsp;the&nbsp;cowboy_rest&nbsp;protocol&nbsp;with&nbsp;cowboy&nbsp;1.0&nbsp;but&nbsp;I&nbsp;have&lt;br&gt;<br>
a&nbsp;small&nbsp;crash.&lt;br&gt;<br>
&lt;br&gt;<br>
Here&nbsp;is&nbsp;my&nbsp;code:&lt;br&gt;<br>
&lt;br&gt;<br>
&lt;a&nbsp;href=&quot;https://www.friendpaste.com/7O3X4fG4u31gBg9MgW5xg4&quot;&nbsp;target=&quot;_blank&quot;&gt;https://www.friendpaste.com/&lt;u&gt;&lt;/u&gt;7O3X4fG4u31gBg9MgW5xg4&lt;/a&gt;&lt;br&gt;<br>
&lt;br&gt;<br>
Could&nbsp;you&nbsp;tell&nbsp;me&nbsp;if&nbsp;I&nbsp;correctly&nbsp;use&nbsp;cowboy_rest&nbsp;for&nbsp;the&nbsp;PUT&nbsp;verb?&nbsp;I&nbsp;have&lt;br&gt;<br>
seen&nbsp;is_conflict/2,&nbsp;but&nbsp;I&nbsp;don&#39;t&nbsp;know&nbsp;how&nbsp;to&nbsp;use&nbsp;it.&lt;br&gt;<br>
&lt;br&gt;<br>
2.&nbsp;I&nbsp;would&nbsp;like&nbsp;to&nbsp;change&nbsp;the&nbsp;response&nbsp;code,&nbsp;but&nbsp;I&nbsp;get&nbsp;the&nbsp;error.&nbsp;Is&nbsp;it&lt;br&gt;<br>
possible?&lt;br&gt;<br>
&lt;br&gt;<br>
Thank&nbsp;you.&lt;br&gt;<br>
