您好我想在django中提交表单后重定向到上一个。它成功重定向到上一页但没有发生后期操作。如果删除action属性，我可以成功发布数据。
这是我的表单模板。
if (Build.VERSION.SDK_INT>=Build.VERSION_CODES.M) {
// call that method
}
这是views.py文件
{% extends 'musicapp/base.html' %} {% block content %}
<!-- <h1>New post</h1> -->
<form method="POST" action={{ request.META.HTTP_REFERER }} class="post-form">{% csrf_token %}
<div class="add_track_form" >
<div class="col-sm-6">
<section class="panel panel-default">
<header class="panel-heading font-bold">Add Genre</header>
<div class="panel-body">
<form action="{% url 'post_list' %}" role="form">
<div class="form-group">
<label>Title</label>
{{ form.name }}
</div>
<input type="hidden" name="next" value="{{ request.path }}">
<button type="submit" class="btn btn-sm btn-default">Submit</button>
</form>
</div>
</section>
</div>
</div>
</form>
{% endblock %}
这些是URL路由。

看看这个：
<input type="hidden" name="next" value="{{ request.path }}" />
request.path提供当前页面的路径，而不是之前的路径。因此，您当前正在提交表单提交的同一页面的下一个值。
{{ request.META.HTTP_REFERER }}提供引荐页面。那么为什么要将表单发布到上一页呢？但应注意，这可能具有值None（或引用页面可能来自另一个域）。
我假设您有表单的动作参数，并且您的“下一个”隐藏输入的值已切换。否则，您可能会有不必要的复杂逻辑。
答案 1 :(得分：1)
你有两种形式，它们是嵌套的。内部表单使用GET（如果没有指定，则默认使用GET），外部表单使用POST。这纯粹是混乱，你不应该这样做。如果你解决了这个问题，我相信这个bug也会得到解决。
{{ request.META.HTTP_REFERER }}不一定是您考虑的上一页。你不应该这样使用它。我会使用GET（例如使用'?prev=/url/before/form/'）来记住用户来自哪个页面。
答案 2 :(得分：0)
替换你的urls.py
url(r'^$', views.home, name='post_list'),
与
url(r'^postlist/$',views.home, name='post_list'),
并以您的形式
<form action="{% url 'post_list' %}" role="form">
是
<form action="/postlist" role="form" method="POST">

所以我通过比较我们点击链接的URL然后根据之前的设置隐藏字段来解决我的问题
URL (request.META.HTTP_REFERER)并根据我从模板中获取的标志值重定向。
这是我的模板
{% extends 'musicapp/base.html' %} {% block content %}
<!-- <h1>New post</h1> -->
<form method="POST" class="post-form">{% csrf_token %}
<div class="add_track_form" >
<div class="col-sm-6">
<section class="panel panel-default">
<header class="panel-heading font-bold">Add Genre</header>
<div class="panel-body">
<div class="form-group">
<label>Title</label>
{{ form.name }}
</div>
{% if 'track/new/' in request.META.HTTP_REFERER %}
<input class="form-control" type="hidden" value = 0 id="flag" maxlength="50" name="flag" type="text">
{% else %}
<input class="form-control" type="hidden" value = 1 id="flag" maxlength="50" name="flag" type="text">
{% endif %}
<button type="submit" class="btn btn-sm btn-default">Submit</button>
</div>
</section>
</div>
</div>
</form>
{% endblock %}
这是观点功能：
def genre_new(request):
if request.method == "POST":
form = AddGenreForm(request.POST)
if form.is_valid():
post = form.save(commit=False)
redirect_flag = request.POST.get("flag", "") # redirect to different places depending upon where it was clicked
post.save()
genres = Genre.objects.all()
print redirect_flag
if redirect_flag == '0':
return HttpResponseRedirect(reverse('post_new'))
elif redirect_flag == '1':
return HttpResponseRedirect(reverse('genre_list'))
else:
return HttpResponseRedirect('/')
else:
form = AddGenreForm()
return render(request, 'musicapp/genre_edit.html', {'form': form})
有更简单的方法吗？
答案 4 :(得分：0)
我认为我有一个更简单的方法。
模板：
<div hidden>
<input name="url_get" value={{ url_ref }}>
</div>
查看：
url_get = request.POST.get('url_get')
if url_get:
url_ref = url_get
else:
url_ref = request.META.get('HTTP_REFERER')
args['url_ref'] = url_ref
所以，我们总是有第一个网址

这似乎很长一段时间了，但应用了伊恩·普林斯（Ian Prince）的推理。请注意所做的一些更改。
{% extends 'musicapp/base.html' %} {% block content %}
<!-- <h1>New post</h1> -->
<form method="POST" class="post-form">{% csrf_token %}
<div class="add_track_form" >
<div class="col-sm-6">
<section class="panel panel-default">
<header class="panel-heading font-bold">Add Genre</header>
<div class="panel-body">
<form action="{% url 'post_list' %}" role="form">
<div class="form-group">
<label>Title</label>
{{ form.name }}
</div>
<input type="hidden" name="next" value="{{ request.META.HTTP_REFERER }}">
<button type="submit" class="btn btn-sm btn-default">Submit</button>
</form>
</div>
</section>
</div>
</div>
</form>
{% endblock %}
这些更改包括：
action='{{ request.META.HTTP_REFERER }}'
<!-- although this was posted as: action={{ request.META.HTTP_REFERER }} -->
和以下内容的更改：
value="{{ request.path }}"
收件人：
value="{{ request.META.HTTP_REFERER }}"
那解决了我的问题。我希望它能解决您的问题
