home.html

{% extends 'base.html' %}


<!DOCTYPE html>

  <head>
    {% block head %}
    <title>home</title>
    {% endblock %}
  </head>

  {% block body %}
    <div class="container">

    <form  method="post">
      {% csrf_token %}
      {{ form.as_p  }}

      <button type="submit" >Submit</button>
    </form>
  </div>

{% endblock %}
</html>

和浏览器网址

我的问题是 home.html 文件中的 {{ form }} 没有被渲染。{{ form.as_p }} 也不起作用。

表单标签(输入)无法出现在网页(浏览器)中。

终端中没有显示任何错误。

请帮我找出错误。

Answer 1

其工作原理是将类更改为函数。

def HomeView(request):
    form = HomeForm()
    return render(request, 'accounts/home.html', {'form': form})

也改变了

url(r'^$',views.HomeView)

在 urls.py 中
