Question

içeren ben şu modeli

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) 

Ben aşağıdaki arama sorgusu

Ben ise server.host

için aşağıdaki dize tarafından aramanıza gerek

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] 

bir hatayı olsun aşağıdakileri eklemeyi deneyin

Q(server__contains=form.cleaned_data['host']), 

Exception Type:  TypeError 
Exception Value:
