在我的 Django 应用程序中,我有以下 models.py:
from django.db import models
import datetime
class Job(models.Model):
name = models.CharField(max_length = 250, null = False)
user = models.CharField(max_length = 30, null = False)
command = models.CharField(max_length = 1000, null = False)
whenToRun = models.DateTimeField('Run Date', null = False)
output = models.CharField(max_length = 100000, null = True)
class Host(models.Model):
jobs = models.ManyToManyField(Job, blank = True)
name = models.CharField(max_length = 100, null = False)
hasRun = models.BooleanField(default = False)
我在https://docs.djangoproject.com/en/dev/topics/db/examples/many_to_many/的指导下在 Host 类中添加了作业分配。我能够毫无问题地添加主机(从管理页面),但是当我尝试添加作业时,出现以下错误:
Exception at /admin/Minion/job/add
<class 'Minion.models.Host'> has no ForeignKey to <class 'Minion.models.Job'>
我也尝试向 Job 类添加 ManyToManyField 分配,但它告诉我名称 Host 未定义。有谁知道我可以做些什么来使这个领域正常运作?提前感谢您的帮助。
