<div dir="ltr">I have used engines and I think they're great for separating unrelated code as well as sharing common code. I did struggle a bit at the beginning (lots of googling) with setting up the app, creating database models in the engine and then installing them in the main app, engine versions, etc. But once I got it all working, everything was a breeze. <div><br></div><div>Best,</div><div>Artan<br><div><div><br></div></div></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><div><br></div><div><br></div><a href="http://lugolabs.com" target="_blank">LugoLabs.com</a><br></div></div></div>

I'm wondering whether it would (user interface and code-complexity issues aside) make sense to store them together. It could provide another useful angle on whether keeping things separate makes sense.<br>
<br>
If putting it all in one database sounds good (or at least, doesn't feel uncomfortable) I'd favour the cheapest approach approach to maintain that delivered a good end-user experience.<br>
<br>
I suspect that means I'd favour a single app, organising the code in namespaces, and sharing all the stuff that's common. It's easy to over engineer stuff like this, and force yourself to jump through costly hoops.<br>
<br>
Namespaces are great. In my experience, we Rails developers don't use them enough.<br>
<br>
If you're reluctant to use namespaces, is there a specific problem you'd be trying to avoid?<br>
<br>
