ActiveAdmin 自定义表单
ActiveAdmin的表单定义，，用的是Formtastic
基础示例ActiveAdmin.register Post do form do |f|f.inputs ‘Details’ dof.input :titlef.input :published_at, label: ‘Publish Post At’endf.actions endend
f.inputs 会显示一个Panel，上面将显示 f.inputs 内定义的所有元素。 f.input 一个输入元素，类似的还有：f.action 操作按钮。 f.actions 操作集合，里面可以定义一个或多个 f.action。
input类型
f.input可以定义多种类型，如check_boxes、select、radio、datalist。 用法：
f.input :authors, :as => :check_boxes, :collection => User.order(“last_name ASC”).all f.input :authors, :as => :check_boxes, :collection => current_user.company.users.active f.input :authors, :as => :check_boxes, :collection => [@justin, @kate] f.input :authors, :as => :check_boxes, :collection => [“Justin”, “Kate”, “Amelia”, “Gus”, “Meg”] f.input :author, :as => :select,:collection => Author.all f.input :author, :as => :select,:collection => Author.pluck(:first_name, :id) f.input :author, :as => :select,:collection => Author.pluck(Arel.sql(“CONCAT(`first_name`, ‘ ‘, `last_name`)”), :id) f.input :author, :as => :select,:collection => Author.your_custom_scope_or_class_method f.input :author, :as => :select,:collection => { @justin.name => @justin.id, @kate.name => @kate.id } f.input :author, :as => :select,:collection => [“Justin”, “Kate”, “Amelia”, “Gus”, “Meg”] f.input :author, :as => :radio,:collection => User.all f.input :author, :as => :radio,:collection => [@justin, @kate] f.input :author, :as => :radio,:collection => { @justin.name => @justin.id, @kate.name => @kate.id } f.input :author, :as => :radio,:collection => [“Justin”, “Kate”, “Amelia”, “Gus”, “Meg”] f.input :admin, :as => :radio,:collection => [“Yes!”, “No”] f.input :book_id, :as => :select,:collection => Hash[Book.all.map{|b| [b.name,b.id]}] f.input :fav_book,:as => :datalist , :collection => Book.pluck(:name)
更多设置 1、设置标签 :label f.input :categories, :label => “类别”
