Where i should put data managers
<p>What is good practice for put data persisters in one place. For now i put model.save() in every controller when i save this object. But i think it is not good resolve, because it can make code duplicates.
I found in ember we have services <a href="https://guides.emberjs.com/v2.8.0/applications/services/" rel="nofollow">https://guides.emberjs.com/v2.8.0/applications/services/</a>, but according documentation it is place for not use data store.</p>

<p>My question is what is best practice for not duplicate data persist code?</p>
