浏览器刷新后Rails Session不会持续存在答案

【问题标题】：Rails Session not persisting after browser refresh浏览器刷新后Rails Session不会持续存在

【问题描述】：

在应用程序内导航和重定向都很好，它只是在浏览器刷新时用户必须重新登录。我只希望会话在浏览器关闭而不是刷新时过期..

我的 session_store.rb

Rails.application.config.session_store :cookie_store, key:
'_workspace_session'

我的会话控制器新建和创建操作：

def new

end


def create
    merchant = Merchant.find_by(email: params[:email])

    if merchant && merchant.authenticate(params[:password])
        session[:merchant_id] = merchant.id
        log_in(merchant)
        flash[:success] = "You were logged in successfully"
        redirect_to merchant_path(merchant.id)
    else
        flash.now[:danger] = "Snap! either your email or password is 
        incorrect. Try again"
        render 'new'
    end

end

【解决方案1】：

这可能是因为您没有会话助手来添加登录商家凭据的 cookie 并在每次重新加载页面时检查它们：首先，将您的 sessions_helper.rb 添加到您的主控制器：

 class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
  include SessionsHelper
end

这是您的会话助手：

 module SessionsHelper

  # Returns the user corresponding to the remember token cookie.
  def current_merchant
    if (merchant_id = session[:merchant_id])
      @current_merchant ||= Merchant.find_by(id: merchant_id)
    elsif (merchant_id = cookies.signed[:merchant_id])
      merchant= Merchant.find_by(id: merchant_id)
      if merchant && merchant.authenticated?(cookies[:remember_token])
        log_in merchant
        @current_user = merchant
      end
    end
  end

 #logs the merchant in.I don't know what your log_in method does there in the    question, if it does the same, you are doing it two times.

 def log_in(merchant)
    session[:merchant_id] = merchant.id
 end


end
