视图中的按钮，用于调用控制器操作以更新数据库列

当单击按钮时，我正在尝试将用户添加到表列（PostgreSQL）中的数组中。按钮单击将注册，但不会调用控制器方法，也不会给出任何错误。

我有以下带有按钮的视图。

views/users/index.html.erb

<%= form_for(Pairing.new, url: users_path, method: :patch, html: { id: 'my_special_form' }) do |f| %>
  <div class="field">
    <%= f.label :supervisor_id %>
    <%= f.collection_select(:supervisor_id, User.where(role: 1), :id, :name) %>
  </div>
  <div class="field">
    <%= f.label :student_id %>
    <%= f.collection_select(:student_id, User.where(role: 0), :id, :name) %>
  </div>
  <%= f.submit %>
<% end %>

以及另一个文件中的 javascript。

assets/javascripts/pair.js

$("#my_special_form").submit(function(){
  var url = this.action + "/" + this.elements["pairing[student_id]"].value;
  $.ajax(url, {
    beforeSend: $.rails.CSRFProtection,
    data: {
      user: {
        supervisor_id: this.elements["pairing[supervisor_id]"].value
      }
    }
    type: 'PATCH',
    dataType: 'JSON',
    success: function(data, textStatus, jqXHR) {
      console.log('Success', data, textStatus, jqXHR);
    }
  });
  return false; // cancels out the normal form submission
});

我正在尝试在控制器中调用此方法

控制器/users_controller

class UsersController < ApplicationController
  before_action :authenticate_user!
  after_action :verify_authorized
  def index
    @users = User.all
    authorize User
  end
  def show
    @user = User.find(params[:id])
    authorize @user
  end
  def update
    @user = User.find(params[:id])
    authorize @user
    if @user.update_attributes(secure_params)
      redirect_to users_path, :notice => "User updated."
    else
      redirect_to users_path, :alert => "Unable to update user."
    end
  end
  def destroy
    user = User.find(params[:id])
    authorize user
    user.destroy
    redirect_to users_path, :notice => "User deleted."
  end
  def pair
    supervisor = User.find(params[:id1])
    student = User.find(params[:id2])
    studentlist = supervisor.select(:supervised_students)
    studentlist << student.
    supervisor.update_attribute(:supervised_students => studentlist)
    @supervisor.save
  end
  private
  def secure_params
    params.require(:user).permit(:role)
  end
end

add_supervisor迁移

class AddSupervisor < ActiveRecord::Migration
  def change
    add_column :users, :supervisor_id, :integer
  end
end

用户模型

enum role: [:student, :supervisor, :admin]
  after_initialize :set_default_role, :if => :new_record?
  has_many :students, class_name: "Users",
                      foreign_key: "supervisor_id"
  belongs_to :supervisor, class_name: "User"
  def set_default_role
    self.role ||= :student
  end

路线.rb

Rails.application.routes.draw do
  devise_for :users
  resources  :users
  resources  :pairings
  resources  :conversations, only: [:index, :show, :destroy] do
    member do
      post :reply
    end
  end
  resources :conversations, only: [:index, :show, :destroy] do
    member do
      post :restore
    end
  end
  resources :conversations, only: [:index, :show, :destroy] do
    collection do
      delete :empty_trash
    end
  end
  resources :conversations, only: [:index, :show, :destroy] do
    member do
      post :mark_as_read
    end
  end
  resources  :messages, only: [:new, :create]
  devise_scope :user do
    authenticated :user do
      root 'pages#index', as: :authenticated_root
    end
    unauthenticated do
      root 'pages#welcome', as: :unauthenticated_root
    end
  end

  root to: 'pages#index'
end
