与ORM的Django错误

Question

我已经开始学习django并且使用ORM(DB mysql)进行INSERT查询时遇到问题.我的模特:

class Record(models.Model):
    id         = models.AutoField(primary_key=True, blank=True),
    schema_id  = models.IntegerField(),
    name       = models.CharField(max_length=50),
    desc       = models.TextField(blank=True)

    class Meta:
        db_table = 'keeper_record'

以下代码是view.py中的句柄后查询:

def add_record(request):
    if request.method == 'POST':
        Record.objects.create(
            schema_id  = request.POST.get('schema_id', 1),
            name       = request.POST.get('name', 'd'),
            desc       = request.POST.get('desc', ' ')
        )

        record.save()

    return HttpResponse('')

但是此代码引发错误:

Request Method: POST

Exception Type: TypeError
Exception Value:

我为python安装了mysql驱动程序,并为项目设置了标准设置,但只删除了csrf

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    #'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
)

我的猜测是你的模型定义中的这些逗号.

您正在设置schema_id模型字段的元组.id = (models.AutoField(...),)

删除尾随的逗号,你应该好好去.

class Record(models.Model):
    id         = models.AutoField(primary_key=True, blank=True), # remove ,
    schema_id  = models.IntegerField(), # remove ,
    name       = models.CharField(max_length=50), # remove ,
    desc       = models.TextField(blank=True)

    class Meta:
        db_table = 'keeper_record'
