Django 前端

<div class="container">

      <form class="form-signin" method="post">{% csrf_token %}
        <h2 class="form-signin-heading">PerfectCRM</h2>
        <label for="inputEmail" class="sr-only">Username</label>
        <input type="text" id="" name="username" class="form-control" placeholder="Username" required autofocus>
        <label for="inputPassword" class="sr-only">Password</label>
        <input type="password" name="password" class="form-control" placeholder="Password" required>
         <span style="color: red">{{ error_msg }}</span>
        <div class="checkbox">
          <label>
            <input type="checkbox" value="remember-me"> Remember me
          </label>
        </div>
        <button class="btn btn-lg btn-primary btn-block" type="submit">Sign in</button>
      </form>

</div> <!-- /container -->

　　如果想給每條視圖函數加驗證只需要導入

　　from django.contrib.auth.decorators import login_required

　　給每個視圖函數加上@login_required
