在Mac 10.8.5上運行Django服務器時出現錯誤

Question

我正在嘗試在Mac上設置Python / Django / Mysql，但在終端中運行此命令時卻不斷收到以下錯誤

Python manage.py runserver

我得到的錯誤是

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

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

我認為您做了類似的事情：

錯誤：

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

正確：

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

因此，您嘗試使用類而不是類實例進行驗證。

Answer 2

您的models.py必須如下所示：

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指示

“未正確聲明模型字段，缺少字段類型名稱后的括號”

您缺少2個字段的括號：

bodytext = models.TextField 
timestamp = models.DateTimeField
