I am new to ruby and rails development and have this question in mind. If i have a concern with scope created say latest_records which gives me latest data for a customer
Now what is the best practice to use scope in this situation. should scopes be in model or in controller?
I read some online articles and it talks about fat model and skinny controller and since scopes are do database related work then i am guessing they should be in model.
Any suggestions or thoughts?
You guessed it right.
Scopes belong to model and needs active record classs object to work on.
Scopes are nothing but a activerecord query divided in parts and it helps look your query elegant and dry.
e.g.
If you want to get users with confirmed emails, you would:
User.where(confirmed: true)
But with scopes in your user model:
scope :confirmed, -> { where(confirmed: true) }
And you would simply:
User.confirmed
For more detailed please refer this answer here
A scope could only be defined in a model so it would have to be on a model.
