我希望能够搜索用户,并将其指向所有用户的列表。
当我尝试搜索功能时,收到此错误:相关字段无效查找:icontains。
它追溯到这一行:
clients = LessonCount.objects.filter(user__icontains=q)
有什么想法吗?提前谢谢!
views.py:
def search(request):
try:
q = request.GET.get('q')
except:
q = None
if q:
clients = LessonCount.objects.filter(user__icontains=q)
context = {
'query': q,
'clients': clients
}
template = 'clients.html'
else:
context = {}
template = 'contact.html'
return render(request, template, context)
models.py:
class LessonCount(models.Model):
user = models.OneToOneField(settings.AUTH_USER_MODEL)
lesson_current_amount = models.PositiveIntegerField(default=0, verbose_name='Current Number of Lessons')
def __unicode__(self):
return str(self.user.username)
class Meta:
ordering = ['-user']
def update_lesson_count(self):
if self.lesson_current_amount > 0:
self.user.is_member = True
self.user.save()
elif self.lesson_current_amount <= 0:
self.user.is_member = False
self.user.save()
else:
pass
答案 0 :(得分:2)
(user__icontains=q)
正在调用用户对象上的icontains查找。我认为你应该做的是(user__username__icontains=q)
,它会对用户的名字进行查询。
