Django2注冊(cè)頁(yè)面`help_text`不能隱藏

環(huán)境：
python3.6 Django2.0

我的注冊(cè)模塊view視圖

class RegisterView(CreateView):
    template_name = 'user/register.html'
    form_class = UserCreationForm

template

{% extends "base.html" %}

{% block main %}
  <h1>Register</h1>
  <form method="post">
    {{ form.as_p }}
    {% csrf_token %}
    <button
        type="submit"
        class="btn btn-primary">
      Register
    </button>
  </form>
{% endblock %}

每一個(gè)表單后都有提示，請(qǐng)問如何隱藏？
