home.html的

{% 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}}没有呈现。 {{form.as_p}}也无效。

表单标签（输入）无法出现在网页（浏览器）中。

并且终端中没有显示任何错误。

请帮我找错。

Answer 1

它通过改变类来运作。

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

html文件中的{{form}}未被呈现
