Alphabetical order Ruby on Rails

Sorting can be done this way:

@posts_categories = Admin::PostCategory.order(name: :asc)

That's if the poss_categories table has the "name" field. If not, just replace with the name of the field to use as sorting criteria.

The asc says that the sort will be done ascending (A-Z or 0 - 10 ...)
