按最接近的数字查找订单

Question

How can I arrange order in Model.where(...).order() to sort the items based on proximity of a number field to assign number?

So, when I request to order for 4, (1...6) would be something like this: [4,5,3,6,2,1]

Answer 1

Sounds like you want the absolute value of the difference between a given number and the field value. For example:

User.order("abs(4 - <your-field-name-here>)")
