python初学，为什么我的HTML页面form表单提交的数据，django存不到数据库啊？

form表单代码段如下

<form class="form-horizontal form-material" >
                        <span>添加卡牌</span>
                        <div class="form-group" style="margin-top: 10px">
                            <label class="col-md-12" style="font-size: 20px">卡牌名</label>
                            <div class="col-md-12">
                                <input id="c_cid" type="text" placeholder="不超过16个字" class="form-control form-control-line">
                            </div>
                        </div>
                        <div class="form-group" style="margin-top: 10px">
                            <label class="col-md-12" style="font-size: 20px">卡牌图案</label>
                            <div class="col-md-12">
                                <input id="c_photo" type="file"  accept = "image/*">
                            </div>
                        </div>
                        <div class="form-group" style="margin-top: 10px">
                            <label class="col-md-12" style="font-size: 20px">卡牌功能</label>
                            <div class="col-md-12">
                                <input id="c_content" type="text" placeholder="卡牌实战功能" class="form-control form-control-line">
                            </div>
                        </div>
                        <div class="form-group" style="margin-top: 10px">
                            <label class="col-md-12" style="font-size: 20px">卡牌背景</label>
                            <div class="col-md-12">
                                <input id="c_back" type="text" placeholder="卡牌背景故事" class="form-control form-control-line">
                            </div>
                        </div>

                        <div class="form-group">
                            <div class="col-sm-12">
                                <button id="publishk" class="btn btn-success" >添加</button>
                            </div>
                        </div>

                    </form>

form表达的js代码：

    function deletek(ths) {
        var c_cid = $(ths).attr("iddd");
        $.ajax({
            url: window.location.href,
            type: "POST",
            data: {'type': 'delete', 'c_cid': c_cid},
            beforeSend: function (xhr, settings) {
                xhr.setRequestHeader("X-CSRFToken", "{{ csrf_token }}");    // csrf
            },
            success: function (data) {
                // data是服务器端返回的字符串
                var dic = JSON.parse(data)
                if (!dic.status) alert(JSON.parse(data).msg);
                else window.location.href = "/card-manage";
            }
        });
    }

    $('#publishk').click(function () {
        var c_cid = $('#c_cid').val();
        $.ajax({
            url: window.location.href,
            type: "POST",
            data: {'type': 'create',
                'c_cid': c_cid,
                'c_photo': this.c_photo,
                'c_back': this.c_back,
                 'c_content': this.c_content},
            beforeSend: function (xhr, settings) {
                xhr.setRequestHeader("X-CSRFToken", "{{ csrf_token }}");    // csrf
            },
            success: function (data) {
                // data是服务器端返回的字符串
                var dic = JSON.parse(data);
                if (!dic.status) alert(JSON.parse(data).msg);
                else window.location.href = "/card-manage";
            }
        });
    });

django代码：

def card_manage(request):
    # 验证登录
    if not request.session.get('admin_uid'):
        return redirect('/my-admin')

    if request.method == 'GET':
        # get返回所有卡牌
        cards = models.Card_List.objects.filter()
        response = {
            'cards': cards,
        }
        return render(request, 'card-manage.html', response)
    if request.method == 'POST':
        p_type = request.POST.get('type')
        response = {'msg': '', 'status': False}
        # 删除卡牌
        if p_type == 'delete':
            c_cid = request.POST.get('c_cid')
            models.Card_List.objects.filter(id=c_cid).delete()
            response['status'] = True

        # 添加卡牌
        if p_type == 'create':
            c_cid = request.POST.get('c_cid')
            c_content = request.POST.get('c_content')
            c_back = request.POST.get('c_back')
            models.Card_List.objects.create(c_cid=c_cid,c_content = c_content,c_back = c_back)
            response['status'] = True
            # 存卡牌图片
            c_photo = request.FILES.get('c_photo', None)
            c_photo_path = 'static/img/c_photo/' + str(c_cid) + '_' + c_photo.name

            if c_photo:
                # 保存文件
                import os
                f = open(os.path.join(c_photo_path), 'wb')
                for line in c_photo.chunks():
                    f.write(line)
                f.close()

            # 吧图片路径存入数据库
            models.Card_List.objects.filter(id=c_cid).update(c_photo='/' + c_photo_path)


        return HttpResponse(json.dumps(response))

程序是个博客系统，想给管理员添加个功能出了问题，每次运行以后页面成功显示，就是form表单的数据存不到数据库里。数据库用的MySQL8，python3.7.。

你调试一下，看看views中进入的是GET还是PSOT，如果是POST，看看是否获取到了前端返回的数据
