当您编辑拥有一个配置文件的用户时，活动管理员删除配置文件并重新创建它，这使得头像图像被回形针删除

我怎样才能让活动管理员只更新嵌套表单而不删除并重新创建它。

这是我的 ActiveAdmin：用户代码

ActiveAdmin.register User do
  menu :priority => 2

  ## Controller
  controller do

    def update
      if params[:user][:password].blank?
        params[:user].delete("password")
        params[:user].delete("password_confirmation")
      end

      if params[:user][:profile_attributes][:avatar].blank?
        params[:user][:profile_attributes].delete("avatar")
      end

      super
    end

    def permitted_params
      params.permit user: [:username, :email, :password, :password_confirmation, :approved, role_ids: [], profile_attributes: [:first_name, :last_name, :date_of_birth, :avatar]]
    end

  end

  #Scopes
  scope :all, default: true
  scope :admins
  scope :editors
  scope :members

  ## Filters
  filter :username
  filter :email

  ## Index
  index do
    column :id
    column :first_name do |user|
      user.profile.first_name unless user.profile.nil?
    end
    column :last_name do |user|
      user.profile.last_name unless user.profile.nil?
    end
    column :username
    column :email
    column :role, :sortable => false
    default_actions
  end

  ## Form
  form :html => {:multipart => true} do |f|

    f.inputs "User Account Details" do
      f.input :username
      f.input :email
      f.input :roles
      f.input :approved
      f.input :password, hint: "leave it blank if you don't want to change it"
      f.input :password_confirmation
    end

    f.inputs "Profile Details",  for:  [:profile, f.object.profile || f.object.build_profile] do |profile_form|
        profile_form.input :first_name
        profile_form.input :last_name
        profile_form.input :date_of_birth, as: :date_select, start_year: Date.today.year-80, end_year: Date.today.year-13

        profile_form.input :avatar, :as => :file, :hint => profile_form.template.image_tag(profile_form.object.avatar.url(:small))
    end

    f.actions
  end

end

这是控制台显示的内容，请注意它删除了配置文件记录并重新创建它，这使得回形针 gem 删除已经更新的图像。

尝试允许 profile_attributes 的 :id 属性

profile_attributes: [:id , ...]

并尝试删除此猴子补丁：

  if params[:user][:profile_attributes][:avatar].blank?
    params[:user][:profile_attributes].delete("avatar")
  end

我有同样的问题。您需要将语义字段用于嵌套属性。这是我的解决方案：

f.inputs "User Fundamentals" do
...
end
if params[:action] == 'edit'
  f.inputs "User Profile" do
      f.semantic_fields_for :profile do |profile_form|
        profile_form.inputs :first_name,:last_name, etc..
      ...
elsif params[:action] == 'new'
  f.inputs :name => "User Profile", :for => [Profile.new] do |profile_form|
        profile_form.inputs :first_name,:last_name, etc..
      ...

希望这可以解决您的问题。
