@keithepleyのコメントの後に答えを変更しました
#Post.find(:all, :conditions => { :approved => true })
Post.where(:approved => true).all
#Post.find(:first, :conditions => { :approved => true })
Post.where(:approved => true).first
or
post = Post.first or post = Post.first!
or
post = Post.last or post = Post.last!
この場所から詳細を読むことができます
Post.find(:all, :conditions => { :approved => true })
Post.all(:conditions => { :approved => true })
named_scope :approved, :conditions => { :approved => true }
Post.approved.all
Post.scoped(:conditions => { :approved => true }).all
Rails 3-4 での方法は次のとおりです。
Post.where(approved: true) # All accepted posts
Post.find_by_approved(true) # The first accepted post
# Or Post.find_by(approved: true)
# Or Post.where(approved: true).first
Post.first
Post.last
Post.all
Use the new ActiveRecord::Relation
stuff that was added in Rails 3. Find more info here: http://guides.rubyonrails.org/active_record_querying.html
Instead of #find
, use #first
, #last
, #all
, etc. on your model, and the methods that return a ActiveRecord::Relation, like #where
.
#User.find(:first)
User.first
#User.find(:all, :conditions => {:foo => true})
User.where(:foo => true).all
