Question

我有一个django模型，包含多个字段，如下所示：

class Sponsor(CommonInfo, Person):
    signature_code = models.CharField(max_length=20, blank=True)
    account = models.ForeignKey(Account)
    department = models.ForeignKey(Department)
    product = models.ManyToManyField(Product, null=True, blank=True, through = 'ProductSponsor')
    accounts = models.ManyToManyField(Account, null=True, blank=True, through = 'AccountSponsor', related_name='sponsoraccounts')

我的观点有：

class SponsorEdit(UpdateView):
    model = Sponsor
    template_name = 'sponsoredit.html'
    fields = ('account', 'department', 'exp_date', 'last_name', 'first_name', 'signature_code', 'comments', 'product', 'accounts')

当我通过在Many to MAny关系中添加一些字段来编辑条目时，我收到以下错误：

AttributeError at /irms/sponsoredit/2
Cannot set values on a ManyToManyField which specifies an intermediary model.  Use irms.ProductSponsor's Manager instead.

问题出在哪里？

Answer 1

在您的模型中，您使用的是function setCellValue(cellName, value) { var ss = SpreadsheetApp.getActiveSpreadsheet(); var sheet = ss.getActiveSheet(); var cell = sheet.getRange(cellName); cell.setValue(value); } setCellValue("A1","Approved");和AccountSponsor。它们是关系的自定义中间表，当您保存ProductSponsor对象时，需要手动设置中间“Sponsor”和“ProductSponsor”对象。类似的东西：

AccountSponsor

Django使用通用视图保存了许多条目
