Can someone tell me what is the equivalent way to do the following line in Rails 4?
has_many :friends, :through => :friendships, :conditions => "status = 'accepted'", :order => :first_name I tried the following:
has_many :friends, -> { where status: 'accepted' }, :through => :friendships , :order => :first_name But I get the following error:
Invalid mix of scope block and deprecated finder options on ActiveRecord association: User.has_many :friends

1 What is Active Record? Active Record is the M in MVC - the model - which is the layer of the system responsible for representing business data and logic. Active Record facilitates the creation and use of business objects whose data requires persistent storage to a database.
2.6 The has_and_belongs_to_many Association A has_and_belongs_to_many association creates a direct many-to-many connection with another model, with no intervening model. This association indicates that each instance of the declaring model refers to zero or more instances of another model.
Polymorphic relationship in Rails refers to a type of Active Record association. This concept is used to attach a model to another model that can be of a different type by only having to define one association.
what is dependent :destroy. Dependent is an option of Rails collection association declaration to cascade the delete action. The :destroy is to cause the associated object to also be destroyed when its owner is destroyed.
Needs to be the second arg:
class Customer < ActiveRecord::Base has_many :orders, -> { where processed: true } end http://edgeguides.rubyonrails.org/association_basics.html#scopes-for-has-many
RESPONSE TO UPDATE:
Put the order inside the block:
has_many :friends, -> { where(friendship: {status: 'accepted'}).order('first_name DESC') }, :through => :friendships If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
