如何对f.select进行排序？

Question

<%= f.select(:company_id, Company.all.collect {|company| [company.name, company.id]}) %> 

如何从A-Z中排序？

Answer 1

<%= f.select :company_id, Company.all.collect{|company| [company.name, company.id]}.sort_by{|a, b| a} %> 

或者

<%= f.select :company_id, Company.all.collect{|company| [company.name, company.id]}.sort{|a, b| a[0] <=> b[0]} %> 

UPD

或者只是<%= f.select :company_id, Company.all.map{ |c| [c.name, c.id] }.sort %> - Phrogz
