</footer><!-- /.post-info -->      <p>Lately I was playing with ZF2 and Doctrine 2, trying to integrate them into one app. There's a nice <a href="http://www.jasongrimes.org/2012/01/using-doctrine-2-in-zend-framework-2/" title="Using Doctrine 2 in Zend Framework 2"><strong>tutorial</strong></a>. Here I will try to solve the most common problems which are happening during this integration.</p>
<h2>Helper "em"</h2>
<p>First of the problems that can occur is the following one:</p>
<div class="highlight"><pre><span class="p">[</span><span class="n">InvalidArgumentException</span><span class="p">]</span>       
<span class="n">The</span> <span class="n">helper</span> <span class="s">&quot;em&quot;</span> <span class="n">is</span> <span class="n">not</span> <span class="n">defined</span><span class="p">.</span>
</pre></div>


<p>If you'll have the same error it's most probably caused by using wrong command for ORM generation. By default in Doctrine you should use:</p>
<div class="highlight"><pre><span class="n">doctrine</span> <span class="n">orm</span><span class="o">:</span><span class="n">schema</span><span class="o">-</span><span class="n">tool</span><span class="o">:</span><span class="n">create</span>
</pre></div>


<p>But in case of <strong>ZF2</strong> this command won't work. You should call instead of it: </p>
<div class="highlight"><pre><span class="p">.</span><span class="o">/</span><span class="n">vendor</span><span class="o">/</span><span class="n">doctrine</span><span class="o">/</span><span class="n">doctrine</span><span class="o">-</span><span class="n">module</span><span class="o">/</span><span class="n">bin</span><span class="o">/</span><span class="n">doctrine</span><span class="o">-</span><span class="n">module</span> <span class="n">orm</span><span class="o">:</span><span class="n">schema</span><span class="o">-</span><span class="n">tool</span><span class="o">:</span><span class="n">create</span>
</pre></div>


<h2>No Metadata Classes to process.</h2>
<p>Check if for sure you have correct path in your <strong>module.config.php</strong> setup for <strong>Annotation Driver</strong>, it should look like:</p>
<div class="highlight"><pre><span class="cp">&lt;?php</span>
<span class="k">namespace</span> <span class="nx">MyNamespace</span><span class="p">;</span>
<span class="c1">//...</span>
<span class="k">return</span> <span class="k">array</span><span class="p">(</span>
    <span class="c1">//...</span>
    <span class="c1">// Doctrine config</span>
    <span class="s1">&#39;doctrine&#39;</span> <span class="o">=&gt;</span> <span class="k">array</span><span class="p">(</span>

            <span class="p">),</span>
            <span class="s1">&#39;orm_default&#39;</span> <span class="o">=&gt;</span> <span class="k">array</span><span class="p">(</span>
                <span class="s1">&#39;drivers&#39;</span> <span class="o">=&gt;</span> <span class="k">array</span><span class="p">(</span>
                    <span class="nx">__NAMESPACE__</span> <span class="o">.</span> <span class="s1">&#39;\Entity&#39;</span> <span class="o">=&gt;</span> <span class="nx">__NAMESPACE__</span> <span class="o">.</span> <span class="s1">&#39;_driver&#39;</span>
                <span class="p">)</span>
            <span class="p">)</span>
        <span class="p">)</span>
    <span class="p">),</span>
<span class="p">);</span>
</pre></div>


<p>Be sure not to forget the part with namespace!</p>
<div class="highlight"><pre><span class="x">namespace MyNamespace;</span>
</pre></div>


<p>After that you should be able to work with Doctrine!</p>
