Question

我正在尝试在我的Mac上设置Python / Django / Mysql，但是当我在终端中运行此命令时，我一直收到以下错误

Python manage.py runserver

我得到的错误是

Marks-MacBook-Air:FirstBlog mmillar$ python manage.py runserver
Validating models...

TypeError: Error when calling the metaclass bases
unbound method contribute_to_class() must be called with TextField instance as first argument (got ModelBase instance instead)

models.py

from django.db import models 
# Create your models here. 

class post(models.Model): 
    author = models.CharField(max_length=30) 
    title = models.CharField(max_length=100) 
    bodytext = models.TextField 
    timestamp = models.DateTimeField

Answer 1

我认为你做过类似的事情：

错误：

class Foo(models.Model):
    bar = models.TextField

正确的：

class Foo(models.Model):
    bar = models.TextField()

因此，您尝试使用类而不是类实例进行验证。

Answer 2

你的models.py必须如下：

from django.db import models 
# Create your models here. 

class post(models.Model): 
    author = models.CharField(max_length=30) 
    title = models.CharField(max_length=100) 
    bodytext = models.TextField()
    timestamp = models.DateTimeField()

Cause ：unbound method contribute_to_class() TypeError - 表示

“模型字段未正确声明，括号后面字段类型名称缺少“

您有两个字段缺少括号：

bodytext = models.TextField 
timestamp = models.DateTimeField
