编辑:问题解决了,现在我又遇到了另一个问题。当应该返回“OK”或“EXISTS”时,数据变量不返回任何内容。
我有一个带叠加效果的模板。 income.html模板有一个表单和一个“添加新类别”按钮,当您单击它时,将显示一个带有小窗体的新窗口(叠加效果)。我不知道为什么,但这个类别没有被创建。看来我在html脚本中遇到了一些错误,但我无法识别它们。
income.html:
(document).ready(function(){
$("#new_cat").live("click", ( function() {
var cat_name = $("#nc").val();
if (cat_name) {
$.get("/cashflow/new_cat/0/", { name: cat_name, account: {{ account }} },
function(data){
if (data == "OK") {
$("#id_category").val(cat_name);
}
if (data == "EXISTS") {
var error = "The category already exists";
alert(error);
}
});
}
else {
var error = "Please enter a name";
alert(error);
}
}))
});
</script>
...
<form>{% csrf_token %}
<label for="name">Name:</label><input type="text" id="nc" />
<input type="submit" value="Submit" id="new_cat" />
</form>
views.py:
@login_required
def income(request, account_name):
account = account_name
if request.method == 'POST':
form = TransForm(user=request.user, data=request.POST)
if form.is_valid():
income = form.save(commit=False)
income.type = 0
income.account = Account.objects.get(
name = account_name,
user = request.user)
income.name = form.cleaned_data['name']
income.category = form.cleaned_data['category']
income.save()
uri = ("/cashflow/account/%s") % str(account_name)
return HttpResponseRedirect(uri)
else:
form = TransForm(user=request.user)
context = {
'TransForm': form,
'type': '0',
'account': account,
}
return render_to_response(
'cashflow/income.html',
context,
context_instance = RequestContext(request),
)
def new_cat(request, tipo):
if request.method == u'GET':
GET = request.GET
if GET.has_key(u'name'):
name = request.GET[u'name']
account = request.GET[u'account']
c = Category.objects.filter(namee=name, account=account)
if c:
s = "EXISTS"
else:
c = Category(name = name, user = request.user,
type = type, account = account)
c.save()
s = "OK"
return HttpResponse(s)
答案 0 :(得分:2)
这看起来有点狡猾:
{ name: cat_name, account: {{ account }} }
请记住,这是在Javascript块中呈现的。 cat_name
是一个JS变量,因此将被正确评估。但{{ account }}
呈现为字符串,因此就JS而言,它是一个文字。所以它需要在引号中:
{ name: cat_name, account: "{{ account }}" }
答案 1 :(得分:1)
在new_cat视图中(我认为tipo等于类型)。
除此之外,我猜错误就在这里:
account = request.GET[u'account']
c = Category.objects.filter(name=name, account=account)
帐户是一个unicode字符串,但您需要一个帐户实例来过滤类别。这样的事应该可以正常工作:
account_st = request.GET[u'account']
account = Account.objects.get(name=account_st)
c = Category.objects.filter(name=name, account=account)
