我有一个需要非常复杂的表格的场景,我需要帮助。
我有三张桌子
create_table "permissions", :force => true do |t|
t.boolean "can_read"
t.boolean "can_create"
t.boolean "can_edit"
t.boolean "can_delete"
t.integer "role_id"
t.integer "resource_id"
t.datetime "created_at"
t.datetime "updated_at"
end
create_table "resources", :force => true do |t|
t.string "class_name"
t.string "class_action"
t.text "description"
t.integer "parent_resource"
t.datetime "created_at"
t.datetime "updated_at"
end
create_table "roles", :force => true do |t|
t.string "name"
t.text "description"
t.datetime "created_at"
t.datetime "updated_at"
end
与模型和协会
class Role < ActiveRecord::Base
has_many :user_roles
has_many :users, :through => :user_roles
has_many :permissions
def to_s
self.name
end
end
class Resource < ActiveRecord::Base
has_many :permissions
has_many :children, :class_name => "Resource", :foreign_key => "parent_resource"
scope :root, lambda {
{
:conditions => "parent_resource IS NULL"
}
}
end
class Permission < ActiveRecord::Base
belongs_to :role
belongs_to :resource
end
假设我们有 2 个角色,管理员,用户,这一次,我需要一个类似于此链接中的图像的表单结构
我怎样才能制作这个表格?提前致谢。
