Jquery 要使用Django保存在数据库中的本地存储阵列

我对某个代码有问题。我还是Django和Jquery的新手

因此，我有一个表单，所有字段都使用中的views.py直接存储在数据库中，我使用self.request.POST['var'] 对于我在后端保存的每个元素。 它是有效的，但是 我的问题是，如何从本地存储存储多个阵列。因为，我也在使用一个模式，在这里我将输入某些值。这些值存储在itemlist中，并在模式中每次单击add时发布一个表行

我想获取所有这些项目/元素并将其保存在数据库中

我曾尝试使用self.request.POST，但不断出现错误，如MultipleInvalid条目。我会把代码发到这里的，谢谢

代码如下。 我还得到了本地存储的结果，如下所示

我想得到所有的模态元素，因为Print itemdata只给出localstorage的值，所以我想存储每个元素的localstorage的值。 我得到的数据是这样的

[{“受邀者id”：“85”，“受邀者代码”：“01086”，“受邀者描述”：“1/2输入编程”，“充电类型”：“R”，“计量单位id”：“33”，“计量单位代码”：“OT”，“数量”：“1” ，“折扣金额”：“1”，“折扣金额”：“单位成本”：“1231.00”，“总金额”：“1231.00”，“净金额”：“1231.00”，“可增值税”：“0”，“增值税免税”：“1231.00”，“增值税零税率”：“0”，“增值税金额”：“0.00” 分公司id:“5”，“分公司代码：”“HO”，“部门：”“34”，“部门代码：”“CCI”，“员工id:”“647”，“员工代码：”“010019700”，“员工姓名：”“MARIA DORIS ABADILLA”，“备注：”“12312” “}]

我想将这些值按元素存储在数据库中，但我很难删除或更改它们。 我试过self.object.POST['invitem\u id'，通常还有其他的。它说，当我试图检索所有这些内容时，“unicode”对象没有属性“get”

获取itemdata（localstorage值，它是list或dictionary）的Python代码，我需要为每个条目使用self.request.POST

def form_valid(self, form):


    self.object = form.save(commit=False)

    itemdata = self.request.POST['itemdata']

    print itemdata



    self.object.enterby = self.request.user
    self.object.modifyby = self.request.user
    self.object.save()

---

您需要实际显示代码。您是否在使用django表单，或者只是在HTML中创建自己的表单？

def form_valid(self, form):


    self.object = form.save(commit=False)

    itemdata = self.request.POST['itemdata']

    print itemdata



    self.object.enterby = self.request.user
    self.object.modifyby = self.request.user
    self.object.save()
