Sort in Ascending Order Rails

Question

Hi I have this model

Model item

class Inventory::Item < ActiveRecord::Base
  has_many :types, :class_name => \"ItemType\"
  attr_accessible :na         


        

Answer 1

For making ASC (Default sorting mode) for name kind of fields (Alphabets),

You can use ORDER BY Clause in MySQL

Hence, In Rails you can simply use

Model.order(:field_name)

Answer 2

To retrieve records from the database in a specific order, you can use the order method:

Item.order(:name)

by default this sorts ascending.

Answer 3

In your query, you can use/add ORDER BY itemType ASC

Answer 4

Something like this should do the trick...

ItemType.includes( :item ).order( 'inventory_items.name DESC' )

Also, if you need to do this in many locations, you can accomplish the same thing by providing an :order parameter to your has_many call, instead - http://apidock.com/rails/ActiveRecord/Associations/ClassMethods/has_many.

Answer 5

You can also set default order in your Model like this:

default_scope order("#{self.table_name}.item_name ASC")

This will sort items by item_name without any change in controller
