老师，您好，html中没有生成输入框，代码如下： <form class="form-horizontal" action="." method="post"> {% csrf_token %} <!-- {{ form.as_p }} --> <div class="form-group"> <label for="{{ form.username.id_for_label }}" class="col-md-5 control-label" style="color:red"><span class="glyphicon glyphicon-user"></span>Username</label> <div class="col-md-6 text-left">{{ form.username }}</div> </div> <div class="form-group"> <label for="{{ form.password.id_for_label }}" class="col-md-5 control-label" style="color:blue"><span class="glyphicon glyphicon-floppy-open"></span>Password</label> <div class="col-md-6 text-left">{{ form.password }}</div> </div> <input type="submit" value="Login"> </form> 查看网页时，只显示了username和password的字段我中，没有显示输入框，请老师指点一二。谢谢。
