我有以下模型
class Command(models.Model):
server = models.ForeignKey(Server)
user_login = models.CharField(max_length=100)
user_run = models.CharField(max_length=100)
host = models.CharField(max_length=100)
ip = models.CharField(max_length=100)
session = models.CharField(max_length=100)
command = models.TextField()
ts = models.DateTimeField(auto_now_add=True)
version = models.CharField(max_length=100)
type = models.CharField(max_length=100)
我有以下搜索查询
cmds = Command.objects.filter(Q(user_login__contains=form.cleaned_data['loguser']),
Q(user_run__contains=form.cleaned_data['runuser']),
Q(host__contains=form.cleaned_data['loghost']),
Q(command__contains=form.cleaned_data['command']),
Q(server__contains=form.cleaned_data['host']),
Q(session__contains=form.cleaned_data['session'])) \
.order_by('-id')[:100]
我需要通过以下字符串搜索 server.host
如果我尝试添加以下内容，就会出错
Q(server__contains=form.cleaned_data['host']),
Exception Type: TypeError
Exception Value:
Related Field has invalid lookup: contains
Exception Location: /usr/lib/python2.5/site-packages/django/db/models/fields/related.py in get_db_prep_lookup, line 156
form.cleaned_data['host']将包含一个主机名的文本字符串。
