没有路由匹配{：action =＆gt;＆＃34; index＆＃34;，：controller =＆gt;＆＃34; admin / genius＆＃34;}，缺少必需的密钥：[：cohort_id]

Question

我有一个activeadmin rails 5应用程序，即使显示路由，我也会收到无路由匹配错误。

Rails路由

new_admin_cohort GET      /admin/cohorts/new(.:format)

我正在尝试将用户资源嵌套在Cohort资源下，在那里我可以共同创建用户和同一个群组或一个群组和一个群组内的多个用户（到目前为止还无法做到）

用户模型

ActiveAdmin.register User do 
belongs_to :cohort, :finder => :find_by_resource_key!#optional: true
permit_params :avatar, :name, :classroom_id, :first_name, :cohort, :last_name, 
:username, :email, :email2, :cell, :password, :password_confirmation, 
:stipend, :address, :benchmarks, :genius, :attendance_id, :users_id, 
:cohort_id, :city, :projects_attributes, avatar_attributes: [:_destroy]
config.batch_actions = true
menu priority: 4
duplicable?

controller do
 def find_resource
  User.find_by(resource_key: params[:id])
 end
end


  index do
    selectable_column
    id_column :cohort_id
    column :first_name
    column :last_name
    column :email
    column :email2
    column :username
    column :address
    column :cell
    column :projects
    column :sign_in_count
    column :created_at
    image_column :avatar, style: :thumb

    actions
  end

 form do |f|
  f.inputs do
   f.semantic_errors *f.object.errors.keys
   f.input :genius
   f.input :cohort_id
   f.input :city
   f.input :cell
   f.input :email
   f.input :password, input_html: { autocomplete: "new-password" }
   f.input :email2
   f.input :username
   f.input :avatar, as: :file
  if f.object.avatar.present?
    f.semantic_fields_for :avatar_attributes do |avatar_fields|
     avatar_fields.input :_destroy, as: :boolean, label: 'Delete?'
  end
end
f.inputs 'Projects' do
    f.has_many :projects, allow_destroy: true,
                              new_record: true do |u|
        u.input :app_name
        u.input :coding
        u.input :project_details
        u.input :start_date
        u.input :github
        #end
       end
   f.actions
        end
       end
     end
   end

队列模型

ActiveAdmin.register Cohort do 
permit_params :city, :cohort_id, :genius, users_attributes: [:last_name, :users_id, :cohort, :username, :genius, :cohort_id, :city, :email, :email2, :cell, :stipend, :project], attendances_attributes: [:present, :absent, :halfday, :class_date], classroom_attributes: [:id, :body, :_destroy]

menu priority: 3
config.batch_actions = true
duplicable?
#active_admin_importable
sortable tree: true

form do |f|
  f.inputs 'Hgp Cohorts', :body
  f.inputs do
    f.input :city, label: "Office Location"
    f.input :cohort, label: "Cohort Number"
  end
  f.inputs "Geniuses" do
    f.has_many :users,allow_destroy: true,
                          new_record: false do |a|
      a.input :genius
      a.input :cell
      a.input :email
      a.input :password, input_html: { autocomplete: "new-password" }
      a.input :email2
      a.input :username
      a.input :avatar, as: :file
      if user.object.avatar.present?
        uuser.semantic_fields_for :avatar_attributes do |avatar_fields|
         avatar_fields.input :_destroy, as: :boolean, label: 'Delete?'
      end
   end
  end
end
  f.actions
end
index do
 selectable_column
 id_column
 column :city
 column :cohort
 actions
end
