NameError: uninitialized constant User
<p>I am using the rails-devise apps with Rails composer. Everything seems fine until I try to interact with the model in the console.
I tried the commands:</p>

<pre><code>rails console
User.all
</code></pre>

<p>And I get the following error from the console:</p>

<pre><code>NameError: uninitialized constant User
