Group objects by specific column in admin page
<pre><code>class Attack(models.Model):
    action_id = models.IntegerField()
    village_id = models.IntegerField()
    unit_name = models.CharField(max_length = 30)
    enemy_village_id = models.IntegerField()
    attack_start = models.DateTimeField()
    created_datetime = models.DateTimeField(auto_now_add = True)
</code></pre>

<a href="https://i.stack.imgur.com/ItcJv.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ItcJv.png" alt=""></a>

<a href="https://i.stack.imgur.com/odB0o.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/odB0o.png" alt=""></a></p>

<p>And when i click on some action id i want to see view like in first screen but only for this id.
I have no idea how to do it... I tried add custom view but it is not that simply so maybe someone know solution for my problem.</p>
