我试图在django中使用formset动态添加多个表单 . 我使用ajax发送客户端添加表单的请求 . 我创建了一个add_another按钮来添加formset . 每当用户单击此按钮时，将进行计数增量，并通过ajax将请求发送到服务器（到我的django的视图） . 我的代码如下所示：
views.py
def trial_balance(request):
formcount = 1
if request.is_ajax():
count = request.POST.get('mycount', formcount)
formcount = count
myformset = formset_factory(DateRangeForm,extra=formcount)
if request.method == "POST":
f = myformset()
if f.is_valid():
else:
f = myformset()
args['formcount'] = formcount
args['myformset'] = f
return render(request, 'trial_balance.html', args)
trial_balance.html
<script>
$(document).ready(function(){
$("#add_another").click(function(){
count = {{ formcount }};
count++;
alert(count);
$.ajax({
url: "/report/trial-balance",
data: { 'mycount' : count}
}).done(function() {
alert("DONE");
}).fail(function() {
alert("FAIL");
});
});
});
</script>
<div>
<form action="" method="POST"> {% csrf_token %}
{{ myformset.as_p }}
<button id="add_another">add another</button>
<input type = "submit" value = "See Results" id = "daterangeresult">
</form>
我总是得到失败警报，当从views.py打印formcount的值时，即使单击该按钮，我也总是得到值1 .
