ng-if change value in view
<p>I'm new in angularJS, here is my issue:
 I would like to know what is the syntax for doing this:
i would like to put the value to <code>'0'</code> if <code>user.fields[5].value=undefined</code> I tried this with <code>ng-if</code> but it's not working, i don't know the syntax and i don't know if <code>ng-if</code> is appropriate for doing this. Maybe <code>ng-init</code> is better, i don't know can you help me pls ?</p>

<p>Here is my code:</p>

<pre><code>ng-if="user.fields[5].value==undefined[user.fields[5].value='0']"&gt;{{user.fields[5].value}} 
</code></pre>
