django - django ajax POST 上的 405 错误

Question

我有一个带有整数字段的模型，它会在用户点击时增加，比如“投票这个”按钮。

该按钮仅显示在详细信息 View 中。为了增加投票计数，它发送一个 ajax POST。问题是 django 甚至在执行 View 之前返回 405(不允许的方法)错误。什么可能导致这种情况？

这是我的代码:

views.py(不会被执行)

@require_POST
def vote_proposal(request, space_name):

    """
    Increment support votes for the proposal in 1.
    """
    prop = get_object_or_404(Proposal, pk=request.POST['propid'])
    proposal_form = VoteProposal(request.POST or None, instance=prop)

    if request.method == "POST" and request.is_ajax:
        if proposal_form.is_valid():
            vote = proposal_form.cleaned_data['propid']
            vote.support_votes += 1
            vote.save()
            msg = "The vote has been saved."
        else:
            msg = "The vote didn't pass validation."
    else:
        msg = "An error has ocurred."

    return HttpResponse(msg)

jQuery代码:

<script type="text/javascript">
    function upvote(proposal) {
        var request = $.ajax({
            type: "POST",
            url: "../add_support_vote/",
            data: { propid: proposal }
        });

        request.done(function(msg) {
            var cur_votes = $("#votes span").html();
            var votes = cur_votes += 1;
            $("#votes span").html().fadeOut(1000, function(){
                $("#votes span").html(votes).fadeIn();
            });
        });

        request.fail(function(jqXHR, textStatus) {
            $("#jsnotify").notify("create", {
                title:"Couldn't vote the proposal",
                text:"There has been an error." + textStatus,
                icon:"alert.png"
            });
        })
     }
</script>

网址.py

urlpatterns = patterns('e_cidadania.apps.proposals.views',

    url(r'^$', ListProposals.as_view(), name='list-proposals'),

    url(r'^add/$', 'add_proposal', name='add-proposal'),

    url(r'^(?P<prop_id>\w+)/edit/$', 'edit_proposal', name='edit-proposal'),

    url(r'^(?P<prop_id>\w+)/delete/$', DeleteProposal.as_view(), name='delete-proposal'),

    url(r'^(?P<prop_id>\w+)/', ViewProposal.as_view(), name='view-proposal'),

    url(r'^add_support_vote/', 'vote_proposal'),

)

模板

<div id="votes">
    <span style="font-size:30px;text-align:center;">
        {{ proposal.support_votes }}
    </span><br/>
    <button onclick="upvote({{ proposal.id }})" class="btn small">{% trans "support" %}</button>
</div>

问题不会是由相对 URL 引起的 url: "../add_support_vote/"在 $.ajax ?我可以想象可能会调用另一个不允许 POST 的 View 而不是 vote_proposal()取决于您触发 Ajax 调用的页面的位置。
