Question

我正在开发一个 django 应用程序，在该应用程序中，我试图通过 javascript 单击按钮将变量的值发送到后端。

javascript代码：

$(document).on("click", "#filter", function (e) {

      IUPredscorethreshold = 0.4

      $("#ksNetwork").empty();

      ksInteractionNetwork('{% url "camkinetv2:newinteractors_intnet" tab1.caMKipedia_Id IUPredscorethreshold %}');

 });

网址.py

path(

        "dataJson/newinteractors_intnet/<str:geneId>/<str:IUPredscorethreshold>",

        views.newinteractors_intnet,

        name="newinteractors_intnet",

    ),

视图.py

@csrf_exempt

def newinteractors_intnet(request, geneId, IUPredscorethreshold):

    print("IUPredscorethreshold:" + IUPredscorethreshold)

.

.

.

.

.

some computation

    graphData = {"nodes": uniquenodesdata, "links": linksdata}

    response = JsonResponse(graphData)

    return response

当我执行此代码时，我收到以下错误：

NoReverseMatch at /v2/search/SARS_CoV_2/GID1716

Reverse for 'newinteractors_intnet' with arguments '('GID1716', '')' not found. 1 pattern(s) tried: ['v2/dataJson/newinteractors_intnet/(?P<geneId>[^/]+)/(?P<IUPredscorethreshold>[^/]+)$']

Exception Value:    

Reverse for 'newinteractors_intnet' with arguments '('GID1716', '')' not found. 1 pattern(s) tried: ['v2/dataJson/newinteractors_intnet/(?P<geneId>[^/]+)/(?P<IUPredscorethreshold>[^/]+)$']

我究竟做错了什么？我该如何解决这个问题。我仍处于 django 的学习阶段，我无法弄清楚如何解决这个错误。

Answer 1

错误消息说它找不到匹配的 url&nbsp;{% url "camkinetv2:newinteractors_intnet" tab1.caMKipedia_Id IUPredscorethreshold %}。你的 urls.py通过放在它前面来声明IUPredscorethreshold它是一个字符串。str:在您的 javascript 中，您分配0.4给该变量，它是一个整数。因此，您无法解析的网址。将 urls.py 中的路径更改为：&nbsp;path( "dataJson/newinteractors_intnet/<str:geneId>/<int:IUPredscorethreshold>", views.newinteractors_intnet, name="newinteractors_intnet", ),

Answer 2

将您的 Javascript 代码更改为：$(document).on("click", "#filter", function (e) {&nbsp; IUPredscorethreshold = 0.4&nbsp; $("#ksNetwork").empty();&nbsp; let url = '{% url "camkinetv2:newinteractors_intnet" ' + tab1.caMKipedia_Id + ' ' + IUPredscorethreshold + '%}'&nbsp; ksInteractionNetwork(url);});我相信 url 没有正确形成

Answer 3

将javascript行从：更改ksInteractionNetwork('{% url "camkinetv2:newinteractors_intnet" tab1.caMKipedia_Id IUPredscorethreshold %}');&nbsp;为ksInteractionNetwork('{% url "camkinetv2:newinteractors_intnet" tab1.caMKipedia_Id "IUPredscorethreshold" %}'.replace(/IUPredscorethreshold/, IUPredscorethresholdvalues) );以下回答帮助回答
