How to use grape-entity without grape-api?

Question

I am trying to use grape-entity without the grape-api gem. So just use it as a serializers for raw rails controllers.

When trying to present my resource by doing:

present User.all, with: Entities::User

I get that the present method is undefined

How am I suppose to present those resources using the entity? The documentation says to use present

can you try `Entities::User.represent User.all` ? – Chris Feb 27 '17 at 12:39 — Chris, Feb 27 '17 at 12:39

I needed to use Grape Entity as well, outside of Grape (in a basic Rails controller), and I ended up using Chris suggestion:

Entities::MyResource.represent MyResource.first

It works like a charm, thanks!

Additional tip: Once you have an instance of the entity representing the object, you can call `serializable_hash` on it – Allison Sep 04 '20 at 07:04
