没有路线匹配[GET]＆＃34; /session.json" rails + backbone

Question

我在rails中的会话有问题，我也在使用backbone.js - 看起来rails正在寻找一个名为/sessions.js的路由，此外，当我查看控制台时我可以在网络响应中看到NoMethodError in SessionsController#create。此时用户无法登录该站点，但我可以在控制台中看到会话ID。

 class SessionsController < ApplicationController
    respond_to :html #:json

  def new

  end

   def create
      user = User.find_by(email: params[:sessions][:email])
          if user && user.authenticate(params[:sessions][:email])
                session[:current_user_id] = user.id
                log_in user  

                @notice    = true 
          else
                 @notice = false
          end

            respond_to do |format|
                  format.html {render(:text => "not implemented")}
                  # format.js
              end
    end 
# Confirms the correct user.
    def correct_user
      @user = User.find(params[:id])
      redirect_to(root_url) unless current_user?(@user)
    end

      # Remembers a user in a persistent session.
    # def remember(user)
    #     user.remember
    #     cookies.permanent.signed[:user_id] = user.id
    #     cookies.permanent[:remember_token] = user.remember_token
    # end

    #destroys user's session - logout
    def destroy
        log_out if logged_in?
        redirect_to root_path
    end 
end

这是我的会话助手：

    module SessionsHelper

    # Logs in the given user.
  def log_in(user)
    session[:user_id] = user.id
  end

  # returns current user to be easily accessed later
  def current_user
     @current_user ||= User.find_by(id: session[:user_id])
  end

  # is the user even logged in?
  def logged_in?
    !current_user.nil?
  end

  def log_out
    session.delete(:user_id)
    @current_user = nil
  end

end

不确定这是否是问题的一部分，但这是我在Backbone中使用session的视图：

    App.Views.LoginView = Backbone.View.extend({
  el: '#login-view',
  events: { 'submit form':   'authorize' },

  authorize: function () {
    // if (this.submitButton.hasClass('disabled') && !(this.form.data('user-authorized') === true)) {
    //   return false;
    // } else {
    //   this.submitButton.addClass('disabled');
    // }
        var self = this,
         attrs = {
          email: this.emailField.val(),
          password: this.passwordField.val()
        };

    User.authorize(attrs, function (err, user) {
      if (err) { self.loginFailure(); }
      else { self.loginSuccess(); }
    });
    return (this.form.data('user-authorized') === true);
  },

  loginSuccess: function () {
    this.form.data('user-authorized', true);
    this.form.submit();
  },

  loginFailure: function () {
    this.$el.animate({left: '-=20'}, 100);
    this.$el.animate({left: '+=40'}, 100);
    this.$el.animate({left: '-=40'}, 100);
    this.$el.animate({left: '+=40'}, 100);
    this.$el.animate({left: '-=20'}, 100);
    this.emailField.focus();
  },

  initialize: function () {
    this.template = HandlebarsTemplates['login'];
    this.render();
    this.form = this.$el.find('form');
    this.emailField = this.$el.find('#login-email');
    this.passwordField = this.$el.find('#login-password');
    this.submitButton = this.$el.find('#login-button');
  },
  render: function(){
    this.$el.html(this.template);

    $('#login-view').append(this.$el);
  }

});

感谢任何帮助。

在NETWORK选项卡内，在控制台中：

NoMethodError in SessionsController#create

undefined method `[]' for nil:NilClass
    <div class="source " id="frame-source-0">
      <div class="info">
        Extracted source (around line <strong>#9</strong>):
      </div>
      <div class="data">
        <table cellpadding="0" cellspacing="0" class="lines">
