Question

代码：模型

class A1(models.Model):
    user = models.ForeignKey(User)
    field1 = models.CharField(max_length=200)
    field2 = models.CharField(max_length=200)

class A2(models.Model):
        user = models.ForeignKey(User)
        field1 = models.CharField(max_length=200)
        field2 = models.CharField(max_length=200)
        field3 = models.CharField(max_length=200)

用法：

def insertRecord(modelName, fields, user)
    record = modelName(User=user, **fields)
    record.save()

错误：＆＃39; unicode＆＃39;对象不可调用。

输入： modelName：A2 字段：{u＆＃39; field1＆＃39 ;: u＆＃39; d2d2d2＆＃39;，u＆＃39; field2＆＃39;：u＆＃39; e2e2e2＆＃39;，u＆＃39; field3＆＃39;：u＆＃ 39; f2f2f2＆＃39;}类型（字段）：＆＃39; dict＆＃39;

任何解决方案/解决这个问题吗？谢谢，

您必须设置属性：

def insertRecord(modelName, fields, user)
    if modelName == "A1":
        record = A1(User=user)
    else:
        record = A2(User=user)

    for field, value in fields.iteritems():
        setattr(record, field, value)

或简单地说：

def insert_record(model_name, fields, user):
    cls = A1 if model_name == 'A1' else A2
    return cls(User=user, **fields)

循环更新Python记录
