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，我不断收到以下错误

Python manage.py runserver

我得到的错误是

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

模型.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

我认为你做了这样的事情：

错误的：

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。

您的 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()

原因：unbound method contribute_to_class() TypeError- 表示

“模型字段未正确声明，字段类型名称后的括号丢失”

您缺少 2 个字段的括号：

bodytext = models.TextField 
timestamp = models.DateTimeField
