Django通过URL传递kwargs

Question

此部分代码的目的是显示在模板中加入组的所有请求，类似于以下所示：

Request 1 | Add | Delete
Request 2 | Add | Delete
Request 3 | Add | Delete
....

我想要做的是将“添加”和“删除”按钮href设置为视图中的一个功能。但是我想知道将** kwarg从模板传递到视图的正确方法是什么。否则，如果有更好的方法来实现这个目标吗？

模板

{% for asking in requested %}
    <a href={% url 'group_judge_request' group_profile.slug decision=0 %}>Cut {{ asking.user.username }}</a>
    <a href={% url 'group_judge_request' group_profile.slug decision=1 %}>Keep {{ asking.user.username }}</a>
{% endfor %}

URL

url(r'^judge_request/(?P<gslug>[\w-]+)$',
    group_judge_request,
    kwargs={'decision':'decision'},
    name='group_judge_request'),

查看group_judge_restart

def group_judge_request(request, gslug, decision):

查看group_requested_invites

def group_requested_invites(request, gslug):
  ....
  requested = GroupRequestToJoin.objects.filter(group=group_profile.group, checked=False)
  return render(request, "groups/group_requested_invites.html", {
    'requested' : requested,
    })

错误：

Don't mix *args and **kwargs in call to reverse()!

Answer 1

我认为你想使用网址查询。所以你的网址如下：

<a href="{% url 'group_judge_request' group_profile.slug %}?decision=0">Cut {{asking.user.username }}</a>

然后，您可以使用以下命令继续列出查询：

request.META['QUERY_STRING']

Answer 2

我认为没有办法使用内置的url模板标记从模板中传递这样的* kwargs。

有两种方法可以做到这一点，一种是创建两个独立的网址，并将决定作为kwarg传递给视图：

<强> urls.py

url(r'^judge_request_cut/(?P<gslug>[\w-]+)$',
    group_judge_request,
    kwargs={'decision': 0},
    name='group_judge_request_cut'),
url(r'^judge_request_keep/(?P<gslug>[\w-]+)$',
    group_judge_request,
    kwargs={'decision': 1},
    name='group_judge_request_keep'),

<强>模板

{% for asking in requested %}
    <a href={% url 'group_judge_request_cut' group_profile.slug decision=0 %}>Cut {{ asking.user.username }}</a>
    <a href={% url 'group_judge_request_keep' group_profile.slug decision=1 %}>Keep {{ asking.user.username }}</a>
{% endfor %}

或者您可以将整数作为参数传递：

<强> urls.py

url(r'^judge_request/(?P<gslug>[\w-]+)/(?P<decision>\d{1})$',
    group_judge_request,
    name='group_judge_request'),

<强>模板

{% for asking in requested %}
    <a href={% url 'group_judge_request' group_profile.slug 0 %}>Cut {{ asking.user.username }}</a>
    <a href={% url 'group_judge_request' group_profile.slug 1 %}>Keep {{ asking.user.username }}</a>
{% endfor %}
