Ruby on rails 如何对视图中的某些数据进行排序?
我正在使用Ruby 1.8.2和Rails 2.3.11Ruby on rails 如何对视图中的某些数据进行排序?,ruby-on-rails,view,sql-order-by,Ruby On Rails,View,Sql Order By,我正在使用Ruby 1.8.2和Rails 2.3.11 <% @answered_respondents = Inquiry.find(:all, :conditions => ["question_id = (?) AND is_answered = 1 AND is_denied = 0", q.id]) %> <% @answered_respondents.each_with_index do |r, i| %> <% @nene = R
<% @answered_respondents = Inquiry.find(:all, :conditions => ["question_id = (?) AND is_answered = 1 AND is_denied = 0", q.id]) %>
<% @answered_respondents.each_with_index do |r, i| %>
<% @nene = Respondent.find(:all, :conditions => ["id = (?)", r.respondent_id ]) %>
<% @nene.each do |zz| %>
<span class="statis_answered_resp"><%= zz.email %></span>
<% end %>
<% end %>
[“问题id=(?)和被回答=1,被拒绝=0”,q.id])%>
[“id=(?)”,r.responder_id])%>
我想做的是:我想通过电子邮件对我的用户进行排序(zz.email)。如何操作?在模型中创建一个默认范围
Rails2: default_scope :order => 'email ASC'
Rails3: default_scope order('email ASC')
默认值将是所有视图的默认值
对于其他订单,您还可以创建其他范围,例如
Rails2: named_scope :special :order => 'email ASC'
Rails3: scope :special order('email ASC')
要使用therm,只需说ModelName.all.special
至少将ruby升级到1.8.7也是一个好主意
1.9.2也很好,也很好虽然不依赖,但它通常与Rails3一起使用
