Ruby on rails 提取hstore键并将其放入datatable中的列中

我目前正在尝试构建一个表，以显示用户列表，并在单独的列中显示其属性。 有点像：

---

用户1 |用户1电子邮件|用户1管理员角色|用户1组织者角色

---

用户2 |用户2电子邮件|用户2管理员角色|用户2组织者角色

---

用户3 |用户3电子邮件|用户3管理员角色|用户3组织者角色

但是，admin和Organizer属性存储在名为activities的hstore列中

构建数据表时，浏览器返回此错误

DataTables警告：表id=DataTables\u table\u 0-请求的未知 第0行的参数“activities.Organizer”。有关 此错误，请参阅

这是我构建表列的代码 在manage_user_controller.rb中

 private

 def load_columns
  columns = []
  columns << {:data => "id", :title => "ID"}
  columns << {:data => "email", :title => "Email"}
  columns << {:data => "created_at", :title => "Created"}
  columns << {:data => 'activities.organiser', :title => "Organiser Role"}
  columns << {:data => 'activities.admin', :title => "Admin Role"}
  columns << {:data => "id", :title => ""}
  return columns
 end

 def load_columns
  columns = []
  columns << {:data => "id", :title => "ID"}
  columns << {:data => "email", :title => "Email"}
  columns << {:data => "created_at", :title => "Created"}
  columns << {:data => "organiser", :title => "Organiser Role"}
  columns << {:data => "admin", :title => "Admin Role"}
  columns << {:data => "id", :title => ""}
  return columns
 end

private
def load_列
列=[]
列“id”，：title=>“id”}
“电子邮件”列：title=>“电子邮件”}
列“已创建”，：title=>“已创建”}
列“activities.Organizer'，：title=>“Organizer Role”}
列“activities.admin”，：title=>“admin Role”}
列“id”，：title=>“”
返回列
结束

在my users_datatable.rb中

private

 def data
  results = []
  users.each_with_index do |user, index|
   cols = {"id" => "#{user.id}"}
   cols.merge!("email" => "#{user.email}")
   cols.merge!("created_at" => "#{user.created_at}")
   cols.merge!("activities" => "#{user.activities.organiser}")
   cols.merge!("activities" => "#{user.activities.admin}")
   #cols.merge!("activities" => "#{user.activities.admin_events}")
   results << cols
  end
  return results
 end

def data
  results = []
  users.each_with_index do |user, index|
   cols = {"id" => "#{user.id}"}
   cols.merge!("email" => "#{user.email}")
   cols.merge!("created_at" => "#{user.created_at}")
   cols.merge!("organiser" => "#{user.activities.organiser}")
   cols.merge!("admin" => "#{user.activities.admin}")
   #cols.merge!("activities" => "#{user.activities.admin_events}")
   results << cols
  end
  return results
 end

private
def数据
结果=[]
users.each_with_index do| user，index|
cols={“id”=>“#{user.id}”
合并！（“email”=>“#{user.email}”）
合并！（“created_at”=>“#{user.created_at}”）
合并！（“活动”=>“#{user.activities.organizer}”）
合并！（“活动”=>“#{user.activities.admin}”）
#合并！（“活动”=>“#{user.activities.admin_events}”）
结果好的，我设法解决了

在manage_users_controller.rb中

 private

 def load_columns
  columns = []
  columns << {:data => "id", :title => "ID"}
  columns << {:data => "email", :title => "Email"}
  columns << {:data => "created_at", :title => "Created"}
  columns << {:data => 'activities.organiser', :title => "Organiser Role"}
  columns << {:data => 'activities.admin', :title => "Admin Role"}
  columns << {:data => "id", :title => ""}
  return columns
 end

 def load_columns
  columns = []
  columns << {:data => "id", :title => "ID"}
  columns << {:data => "email", :title => "Email"}
  columns << {:data => "created_at", :title => "Created"}
  columns << {:data => "organiser", :title => "Organiser Role"}
  columns << {:data => "admin", :title => "Admin Role"}
  columns << {:data => "id", :title => ""}
  return columns
 end

def load_列
列=[]
列“id”，：title=>“id”}
“电子邮件”列：title=>“电子邮件”}
列“已创建”，：title=>“已创建”}
列“组织者”，标题=>“组织者角色”}
列“admin”，：title=>“admin Role”}
列“id”，：title=>“”
返回列
结束
