Question

提交表单时，它不会发布表单数据，而只是重新加载表单。它事先已经在工作，但是我不确定我所做的更改不能使它工作了。通过管理员发布数据仍然可以正常工作。

我只能在终端中看到“错误”消息： which can be seen here

它也发送get请求而不是post请求。我还测试了删除JS和引导CDN的方法，但是问题仍然相同。

我的代码如下：

这是我的观点。py

def create(request):
if request.method == 'POST':
    form = EventCreateForm(request.POST, request.FILES)
    if form.is_valid():.
        instance = form.save(commit=False)
        instance.author = request.user
        instance.save()
        instance.save_m2m()
        return redirect('event:home')
else:
    form = EventCreateForm()
return render(request, 'event/create.html', {'form': form})

create.html

{% extends "base.html" %}

{% load crispy_forms_tags %}


{% block content %}

{{ form.media }}
<div class="container-fluid">
    <div class="col-md-4">
        <div class="page-header">
            <p> Create an event!</p>
        </div>
        <form  method="post" action="" enctype="multipart/form-data">
                {% csrf_token %}
            {{ form | crispy}}

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



{% endblock %}

Answer 1

您可能已删除了操作。尝试重新添加网址？

  <form  method="post" action="{% url "event:create" %}" enctype="multipart/form-data">

Answer 2

我也遇到过这样的问题。我通过去掉一个包含引导类（更准确地说是 <div class="form-group>"）的 div 标签解决了这个问题。
